RU2381857C1 - Overhung device for clamp of reel at unwinding - Google Patents

Abstract

FIELD: metallurgy.

SUBSTANCE: invention relates to metalworking production field and can be used in lines for sheet unwinding from the reel at manufacturing of roof covering, and also independently for other purposes. Device contains frame, supporting and reciprocal bearings, hollow tube with grooves in cantilever arm, implemented on the miter 120 to each other, screw with bearing, nut, mechanical drive, electric motor, reducer, chain gear and drive chain. For clamp of reel at hollow pipe in grooves there are installed three framework mechanism, consisting of brackets with pivots, links and force clamp. Drive of reel clamp contains screw with nut, by its brackets through pivots connecting to force clamps.

EFFECT: invention provides design simplification and reduction of preparation time of reel to unwinding.

Description

The invention relates to the field of metalworking and can be used in lines for unwinding a sheet from a roll in the manufacture of roofing, as well as autonomously for other purposes.

The famous "Clamping mechanism of the roll during unwinding", ed. M.I. Martynyuk et al., A.S. No. 1805090, bull. No. 12 dated 03/30/93, stated on 12/13/90, B65H 16/06.

It consists of racks, movable chucks with clamping cones, a chuck drive, a screw with a worm gear, a belt drive housing and an electric motor, a brake element, a disk spring package, a support sleeve, a mandrel, and support disks.

Disadvantages: complex device.

It is also known "Device for unwinding roll material", ed. E.I. Khodko et al., A.S. No. 1678731, bull. No. 35 dated 09/23/91, declared 09/10/89., B65D 16/06.

It consists of a frame, a drive, pulling rolls, racks, supports, an axis, a bearing drum, for holding a roll, a slide, a device for controlling horizontal roll with a tripod, level slider and an indicator for controlling runout, floating bearings, a shell, a brake axis, and roll centering regulators .

Disadvantages: complex device.

The prototype of the present invention adopted "Device for unwinding roll material", ed. E.I. Khodko et al., A.S. No. 1678731, bull. No. 35 of 23. 09.91, stated 09.10.89., B65D 16/06.

The technical task of the “Cantilever device for clamping the roll during unwinding” is to simplify the design, reduce the time it takes to prepare the roll for unwinding.

The technical problem is achieved by the use of three devices of the frame structure, located at an angle of 120 ° on the hollow carrier pipe, mounted on the frame in the bearing bearing, the end part fixed in the reciprocal bearing bearing.

The proposed device contains (Figs. 1 and 2) a frame 1, a hollow pipe 2, a bearing 3, a counter bearing 4, a hollow pipe 2 in the cantilever part has three slots 5 made at an angle of 120 °, a screw is installed in the axial part of the hollow pipe 2 6, having a threaded part 7 with a 7.1 thread, for changing the diameter d1 and d2 of the seat with a nut 8, a mechanical drive 9, while the screw 6 in the drive part rotates in the bearing 10 and due to the connections 11 in the amount of nine pieces, through hinges with brackets 12 in the amount of fifteen pieces, changes the position of the frame console traction due to three power clamps 13, changing the distance to the axis of the hollow pipe 2; the drive device consists of an electric motor 14, a gearbox 15, an asterisk 16, a drive chain 17, an asterisk 18, the shutter 19 performs a preventive role, the roll 20 is shown in a fixed state.

An example of a specific implementation: the roll 20 is placed as a seat on the power clamps 13, after which the mechanical drive 9 and during the rotation of the screw 6, due to the increase in diameter from d1 to d2, with the participation of the brackets and hinges 10 and 11, the roll is secured and fixed. The technological process begins after turning on the equipment 14-15-16-17-18-2.
