(54) DEVICE FOR ROLLING AND ROLLING OF THE CLOTH

one

The invention relates to the rubber and textile industry and is intended, in particular, for unrolling and seaming machines when processing cord and technical fabrics.

A device for seaming and web rolling is known, comprising clamping heads with tips for product rollers, hydraulic cylinders with rods for axial movement of the heads, roller bearings, a brake and a drive (1.

In this device, the mechanism for reversing heads is made in the form of pneumatic cylinders and a system connected with the head of levers, which complicates the design, increases the size, but does not impair reliability in operation, for example, when installing rolls of technical fabrics that have significant weight, load, disrupting operation of pneumatic cylinder elements.

In addition, this device cannot be applied to work with commercial rollers having square holes and serving for iiociOBKH tire cord and other technical fabrics.

In order to simplify the construction in the proposed device, each of the heads is mounted inside the rod of the pneumatic cylinder, and the tip

It has the shape of a tetrahedral viiogram of a truncated pyramid

FIG. 1 is a diagram of the proposed device; in fig. 2 - section A-A in FIG. 1, a pneumatic cylinder with a tip for a product roller; in fig. 3 is a view along arrow B in FIG. 1, clamping head with tip and roller bearings.

The device is mounted on racks 1, on which the pkevmoshshindry 2 to 3 are fixed. In the rods of 4 pneumatic cylinders there are clamped heads 5, made in the form of axes mounted on bearings 6.

On the zazhimik heads 5 are located the brake pulley 7 and the drive wand 8.

KoiJ№i of the clamping heads 5 are provided with removable tips 9 for fixing the position of the product roller 10, and for precise installation of the latter serve roller bearings 12 mounted on a chip board 11 and directed 13.

Claims (1)

In order to work with commodity rollers having a square opening, removable tips 9 of clamping heads 5 have the shape of a four-sided twisted-shaped truncated pyralette, which allows fixing the roller 10 without prior orientation of the square opening relative to the axis of the clamping head 5. During operation, in the original the position, the pneumatic cylinders 2 and 3 retracted the clamping heads 5 to the extreme positions, leaving the space between the pillars I and the heads 5 to install the product roller Young roller bearings 12. Then pneumatic ilindry include on roller clamp, the clamping head 5 together with rods 4 are moved in opposite directions and clamped trademark roller. When the clamping heads are supplied to the product roller, the base of the tip 9 is first inserted into the roller hole, the dimensions of which are smaller than the roller hole, so that the shroud has the shape of a truncated pyramid, and as the clamping heads move further, they freely rotate inside the rods 4 in bearings 6, at the same time, the spiral-shaped four-tip nozzles 9 allows them to freely find the exact position in the square hole of the product roller 10. The link of the axis with an asterisk 8 and a pulley 7 is made on the Hiliz joint and dopuskayupem longitudinal movement of the clamping heads at a fixed pulley and sprocket. The tips 9 are made removable, which allows the use of product rolls with different square openings. Claim device for rolling and rolling a web containing clamping heads and tips for product rollers, pneumatic cylinders with rods for moving axial heads, roller bearings, brake and drive, characterized in that, in order to simplify the design, each head is mounted inside the rod pneumosink lindra, and the tip has the form of a four-rotor helical truncated pyramid.
