Description

The invention relates to the production of rubber products, namely to the production of rubber hoses, and can be used for winding a power thread layer on the base of the hoses.

A winding machine is known comprising a vertical stand mounted on a base with a sleeve, on which a bearings are mounted on a rotary plate with bobbins, a thread tensioner, guides for feeding threads from bobbins to it, a drive for rotating _the plate and an axial mechanism Movement of a hose product £ 1J.

In such a machine, the bobbins are open, as a result of which, under the action of centrifugal forces, the threads consumed from the bobbins are ejected beyond the plan- * 1 washer, cling to the stationary parts of the equipment, which leads to frequent breaks.

A winding machine is also known to an assembly for assembling tubular products, comprising a vertical stand mounted on a base with a sleeve, on which a faceplate is rotated in a vertical plane with bobbins radially mounted on both sides with a protective casing, a thread tensioner located on one side of the faceplate and _ guides for supplying yarns to the latter, located on the other side of the faceplate, the drive for rotating the latter and a mechanism for axial movement of the sleeve iedeyu ^lija ·

In this machine, the casing is made closed on all sides and individual for each bobbin, which prevents the ejection of threads under the action of centrifugal forces when the washer plan15 is rotated, it falls off under the action of its own weight pj.

The disadvantages of this machine are the complication of the design of the machine, which makes it difficult to visually observe the clips and reload them, and that when the faceplate is rotated and threads are used from bobbins, the threads fall under the action of centrifugal forces between the faceplate disks and the ends of the bobbins facing the latter, and this leads to jerking and breaking the thread.

The purpose of the invention is to simplify the design of the machine and increase the convenience of its maintenance, as well as to prevent tension and breakage of the threads.

This goal is achieved by the fact that in a winding machine to an assembly for assembling tubular products containing a vertical stand with a sleeve mounted on the base, on which a faceplate rotatable in a vertical plane is mounted with reels radially mounted on both sides with a protective casing located on one side of the faceplate thread tensioner and guides for feeding threads to the latter located on the other side of the faceplate, a drive for rotating the latter and a mechanism for axial movement of the sleeve Elia, protective cover for the bobbins configured in the form of two cylindrical shells mounted concentrically faceplate and the bobbin are disposed between the shells ..

In addition, at the ends of the bobbins facing the faceplate disk, fur pads are installed.

In FIG. 1 shows a winding machine as part of an assembly for assembling tubular products, a general view; in FIG. 2, section A-A in FIG. 1; In FIG. 3 - section BB in figure 2.

The winding machine 1 comprises vertical racks 3 mounted on the base 2, on which sleeves are fastened by bearings 4. On the latter, faceplates 6 are mounted with the possibility of rotation in a vertical plane. They are strengthened on both sides of each faceplate 6 by means of axes 7. bobbins 8, placed between two cylindrical shells 9 and 10, mounted concentrically on the faceplate 6. To supply threads from the bobbin to the sleeve blank on both sides of each faceplate, guides made in the form of a bracket 11 are placed against each bobbin, while the ring faces 6 are fixed on one side tensioners 12, and on the other hand, made in the form of tubes guides 13 for threads. Fur pads 14 are installed on the ends of the reels 8 facing the faceplates. The machine also includes a drive 15 for rotating the faceplates 6, a feeding mechanism 16 for axial movement of the sleeve blank, a device 17 for applying a sleeve layer and a selection device 18.

The winding machine operates as follows.

The thread 19 from the bobbins 8 is fed through the brackets 11 to the ring tensioners 12, and then to the sleeve blank 20. In this case, the threads 19 of the bobbin group 8 on one side of the winding faceplates 6 are wound onto the sleeve blank directly through the brackets 11 and the ring tensioner 12, and the threads of the bobbin group 8 on the other side of the winding plan • washers 6 are fed to the ring ^{3 on 4 of the} weight 12 through the brackets 11 and guides 13. ' When the faceplates 6 are rotated in the opposite direction relative to each other, the threads 19 are wound onto the sleeve blank 20 moved in the horizontal direction by means of the mechanism 16.

The cylindrical shells 9 and 10 between which the bobbins 8 are placed, prevent the ejection of the threads 19 under the action of centrifugal and wind forces and its subsidence under the influence of its own weight, and the fur pads 14, without putting pressure on the rear ends of the bobbins and without hooking the threads, prevent dropping, jerking under tension and breakage of the thread.

Simultaneously with the winding of threads on the sleeve blank 20 by the device 17, a rubber layer is applied. A second thread layer is wound on the sleeve blank in the opposite direction, and then the assembled sleeve is taken off by the device 18 and transferred to subsequent operations (applying a rubber layer, vulcanization, etc.).

Using the proposed machine will improve the convenience of its maintenance by providing visual monitoring of all the bobbins on one side of the winding plate at the same time during operation and the possibility of timely replacement of used bobbins, and will also lead to reduced rejects and increased productivity of the machine by reducing recharge time .
