(54) GUIDING MACHINE FOR ASSEMBLY FOR ASSEMBLY OF HOSE PRODUCTS

one

The invention relates to the production of rubber products, in particular to the production of rubber sleeves, can be used for winding the power yarn layer on the base of the sleeves.

According to the main author. St. N ° 821193 is a known winding machine for a bag assembly unit, comprising a vertical stand mounted on the base with a sleeve, on which is mounted a faceplate rotatable in a vertical plane with a reel radially mounted on both its sides and a protective casing, located on one side of the faceplate nitenate resident and guides for supplying the yarns to the latter, located on the other side of the faceplate drive for rotating the latter and a mechanism for axial movement of the sleeve product, in which the protective the casing for reels is made in the form of two cylindrical shells installed concentrically to the faceplate, and the reels are located between the shells 1.

However, in such a machine, when rotating the faceplate, it is possible to discharge some of the turns of the threads from the reel, which at high speed of rotation of the G1lan1 pushes are pressed against

the inner surface of the outer shell and slide outwards, which leads to its breakage when grazing the fixed parts of the planetary fence. This prevents the use of the coiling plate of this design for rotation speeds in excess of 300 rpm.

The aim of the invention is to increase the reliability when the device operates at the highest rotation speed of the faceplate.

This goal is achieved by the fact that the navigating machine is equipped with annular restrictive collars mounted on the inner wall of the outer shell at its ends.

FIG. 1 depicts a coiling machine included in an assembly assembly.

15 sleeve products, cut; in fig. 2 is a view A of FIG. one.

The coiling machine contains mounted on the base of 1 vertical rack 2, on which by means of bearings 3

20, a sleeve 4 is installed, on the latter, with a possibility of rotation in a vertical plane, a plate washer 5 is installed, on which, by means of axles 6, spools 7 radially mounted on its two sides are fixed,

placed in a protective casing, made in the form of two cylindrical shells 8 and 9, which are mounted concentric to the faceplate 5. On the inner wall of the outer shell .9, limiting flanges 10 are installed at its ends. To supply the threads from the reels to the sleeve blank on either side of the plate, opposite each the spools are guides 11, made in the form of staples, on one side of the faceplate are mounted ring nats 2, and on the other side are tube guides 13 for threads. On the butt ends of the reels 7 facing the plate, fur pads 14 are installed. The machine also includes a drive (not shown) for rotating the faceplates, a swiveling mechanism (not shown) for axial movement of the sleeve blank, a device (not shown) for applying the sleeve section and a selection device (not shown).

Navivochna machine works as follows.

The yarns 15 from the bobbins 7 are guided through the brackets 11 to the ring tensions 12, and then onto the sleeve blank (not shown). In this case, the threads 15 of the group of reels 7 on one side of the faceplate 5 are wound on the back: yutka directly through the brackets 11 and the ring tensioner 12, and the threads of the group of reels 7 of the other side of the faceplate go to the ring tensioner 12 through the brackets 11 and guides 13, made in the form of tubes.

At the turning of the faceplate 5, the threads 15 are wound onto a sleeve blank displaced in a horizontal direction, simultaneously with the thread winding

a rubber layer is applied with a device, then a second layer of threads is rolled in opposite directions onto the sleeve blank, the assembled sleeve is thus taken away with a device and transferred to subsequent operations (application of the outer rubber layer, vulcanization, etc.).

Cylindrical shells 8 and 9, between which reels 7 are located, prevent the ejection of the yarns under the action of centrifugal and wind forces, but to avoid accidental ejection of the yarn from the sheath under the action of m. restrictive shoulder 10.

The use of the invention allows to increase the reliability of the winding machine.
