Description

one

The invention relates to devices for transporting glass sheets and can be used in the glass and building materials industries.

The roller tables are known, consisting of the bearing structure of the drive and the drive rollers, the rotation of which drives the load placed on them when hauling from the roll table at an angle to the main direction of movement of the load 1.

A roller table section is also known for transferring sheet glass from one conveyor to another at an angle thereto, comprising a support frame, horizontal rollers mounted on the frame rotatably driven, and rollers 2.

The drawbacks of such devices are the large waste of glass sheets due to damage to their surface during the transfer from the main conveyor to another at an angle to it. On the surface of the sheets there are scratches, rubbing that worsens the surface of the glass.

The purpose of the invention is to improve the quality of the glass by reducing the hauling effort.

This is achieved by the fact that in the section of the roller table for transferring sheet glass from one conveyor to another, at an angle to it, contains a supporting frame, horizontal rollers mounted on the frame rotatably driven, and the rollers, rollers are provided with clips, each of which, on the axis, there is a roller made with a spherical rim, iric, the axis of the roller is located in a plane perpendicular to the longitudinal axis of the roll.

FIG. 1 shows the proposed roller table section, plan view; in fig. 2 - the same, side view; in fig. 3 shows section A-A in FIG. one.

The rolls 1 are fixed in the frame 2 and are driven in rotation by means of a drive (not shown in the drawing).

Rolls 1 consist of a yoke 3 in which rollers 5 with a spherical rim are fixed on the axis x 4.

A piece weight, for example a sheet 6 of glass, shifting in the direction indicated by the arrow is placed on the roller table. The angles of inclination of the axes of the rollers are chosen so that each roll always contacts the glass sheet at least at two points.

The device works as follows.

When the rollers rotate in the direction indicated by the arrow (counterclockwise), the yoke 1 with the axles 4 fixed in it and the rollers 5 rotates continuously. At the same time, the frictional forces that occur as the contact between the surfaces of the rollers 5 and the sheet 6 are located in the planes of the axes 4,

without creating a rotating moment on the rollers 5, which ensures the transportation of the sheet 6 in the main direction.

When the sheet 6 is rolled back at an angle to the main transport direction, the speed of the rolls 6 in the direction of the rollback is subtracting the speed circumferentially in the direction of rotation of the rolls 1 (transfer speed), as a result of which the rollers 5 contacting the sheet 6 rotate around their own axes 4 with circumferential relative speed equal to

VOT open - in

where FOTK is the absolute speed of the contact point;

FB is the transfer speed at the point of contact (circumferential speed of the roll). Since the sheet 6 during haulage moves along the rotating rollers 6, its sliding along the rolls is eliminated, which leads to a decrease in the haulage resistance and, consequently, to a decrease in the haulage force.

The application of the invention will increase the yield of products by eliminating scrap on the surface of a portable load, such as sheets of glass.
