RU2376135C1 - Method of auto tires utilisation - Google Patents

Abstract

FIELD: motor-car construction industry.

SUBSTANCE: as disclosed by the invention, the method provides for auto tires collecting in a package and supplying by conveyor to milling by cutting. The package is formed by vertical auto tires stacking. Then it is compressed by tension puller placed inside auto tires package. The milling cutter is installed tangentially to package surface being processed, while milling cutter spanning axis is placed in the plane crossing longitudinal axis of package and biased to the above longitudinal axis of package. Face milling cutter is used as milling element with removable cartridges being placed on its face surface. Hard-alloy cutting plates are fixed along concentric circles in the removable cartridges. In addition, auto tires package rotates simultaneously with milling cutter.

EFFECT: simplified technology of processing, reduced size and weight of milling plant allowing for placing it on self-moving vehicle and, consequently, wide range of auto tires can be processed directly in places of their accumulation.

Description

The invention relates to the field of material processing, namely to the processing and disposal of tires.

A known method for the disposal of tires is that the tires are fed to the grinder, the crumbs obtained by grinding are sucked off and fed to a cyclone, from which it is fed to a magnetic separator to separate the metal, then a large fraction of the powder and textiles are separated from the fine fraction of the powder (patent RF №2091225, IPC В29В 17/00, publ., September 27, 1997).

The disadvantages of this method are the complexity of its implementation and the bulkiness of the equipment used.

A known method of processing worn tires is that the tires are collected in a bag, fed to the conveyor for grinding, for example, by milling (RF patent No. 2145541, IPC VB 17/00, publ. 02.20.2000).

The disadvantages of this method are the low unification of auxiliary equipment for the processing of tires of different diameters, as well as its complexity and significant dimensions.

The technical result of the claimed invention is to simplify the processing process, increase the reliability of equipment when expanding the range of processed tires.

The task is achieved in that the tires are collected in a bag, fed to the conveyor for grinding, for example, by milling, according to the invention, a bag of tires is formed by installing them one on the other in the vertical direction, the whole bag is compressed using a clamping device located inside the tire bag and the cutter is set tangent to the surface to be machined by the tire pack with the axis of rotation of the mill in a plane intersecting the longitudinal axis of the tire pack and with the offset of the axis of rotation of the mill from rodolnoy axis of tire package and operate the cutter with an end arranged at its end surface interchangeable cassettes on which are mounted tungsten carbide cutting plate along concentric circles while simultaneously rotating cutter is rotated relative to the cutter package of tires.

The task is also achieved by the fact that the cutting surface of the plates can be performed with a radius corresponding to the radius of the tire in the zone of contact with the latter.

The task is also achieved by the fact that before assembling the tires into a package, each of them can be centered when moving on a conveyor using spring-loaded guides.

The task is also achieved by the fact that after centering the tires can be put on one another on the guide rod of the coupling device, and after assembly of the package of tires they are pulled along the guide rod.

The invention is illustrated by drawings.

Figure 2 - installation diagram in plan;

Figure 3 shows the relative position of tires and cutters;

Figure 4 is the same, view A in figure 3;

Figure 5 is a view B of figure 3 on the end surface of the cutter.

Figure 6 shows a diagram of a clamping device of tires in the state of assembly of the package;

In Fig.7 - the same, in a state of constriction of a package of tires. The installation, which implements the claimed method, comprises a conveyor 1 with spikes 2 fixed on its flexible tape, fixed guides 3 located along the conveyor 1. Guides 5, spring-loaded with springs 4, are pivotally connected to the fixed guides 3. On the side of the spring-loaded guides 5 is installed loading table 6 with a clamping device 7. Directly at the loading table is an end mill 8 with a drive shaft 9. The mill 8 is installed tangentially to the surface to be machined pack this tire 10 with the location of the axis of rotation 11 of the shaft 9 of the cutter 8 in a plane intersecting the longitudinal axis 12 (located, for example, vertically) of the tire package (for example, in a horizontal plane) and with an offset of the axis 11 from the axis 12. Cutter 8 is placed on its end surface with interchangeable cartridges 13, on which carbide cutting inserts 14 are fixed along concentric circles.

The cutting surface of the plates 14 is made with a radius corresponding to the radius of the tire in the zone of contact with the latter.

The clamping device is made in the form of a guide rod 15, consisting of several links 16, connected pivotally with the formation, for example, of a hinged four-link. In the state of formation of tires in the package, links 16 are elongated along the longitudinal axis 12, and to tighten the package, the top of the four-link is stretched towards the loading table 6 with the possibility of pressing tires to it with links 16.

Installation works as follows. Tires 10 are moved using conveyor 1. Spikes 2 on a flexible conveyor belt 1 engage a tire whose edges interact with fixed guides 3. At the exit from the fixed guides 3, spring-loaded guides 5 center each tire 10 before it hits the loading table 6. At the same time, each the tire 10 is put on the guide rod 15 (see Fig.6). After the formation of the package of tires 10, the latter are pulled together and pressed against the loading table 6 by a clamping device (as shown in Fig. 7).

Then, the entire package is milled using the cutter 8, while the loading table 6 is rotated together with the package of tires 10 around axis 12. With this organization, the tires are processed with minimal losses and with the formation of crumbs of the best quality with minimal installation dimensions and simplicity of the device.

The implementation of the milling cutter 8 cassette allows you to use carbide cutting elements 14 with the selection of their relative position on the cartridge 13 depending on the type of tires and processing mode.

Thus, when using the described processing method, the technological process is simplified, the design is simplified, the dimensions and weight of the entire installation are reduced, which allows you to place the entire installation on a self-propelled vehicle. With this solution to the problem, it is possible to process tires directly in places of their accumulation.
