Description

 The invention relates to equipment for assembling tires of pneumatic tires, both diagonal and radial, mainly for passenger cars and can find application in the tire industry, in particular in assembly shops.

Known installation for the assembly of tires of pneumatic tires, containing an assembly drum, a template for side rings, a mechanism for crimping and control panel [1]
However, it is not possible to assemble radial tires with this installation, with the exception of only the carcasses of these tires.

Another installation for assembling tires of pneumatic tires is known, comprising a carcass assembly device including an assembly drum and a bead ring template, a parallel device for assembling belt-tread bracelets and forming carcasses with coaxially assembled assembly drums mounted on the frame, storage and supply means tire parts for assembly drums, a drive for the preparation of treads, a means for feeding the blanks of the tread to the drum and a means for feeding the blanks of the tread from tool storage ring to their supply to the drum, mounted between the device for assembling frames and assembly apparatus belt-tread molding and perpendicular to their longitudinal axes, means of transport and parts of carcasses of radial tires within the facility [2]
However, the known installation is complex and occupies a large production area, and it is also impossible to assemble diagonal tires on this installation.

 The technical result of the image is the creation of a more universal design with advanced technological capabilities with less space requirement.

 To achieve a technical result in an installation for assembling tires of pneumatic tires, comprising a carcass assembly device including an assembly drum and a bead ring template, a parallel device for assembling belt-tread bracelets and forming carcasses with coaxially assembled assembly drums mounted on the frame, storage means and feeding tire parts to assembly drums, a drive for blanking the treads, means for feeding the blanks of the tread to the drum and means for feeding the zag the removal of treads from the drive to the means for feeding them onto the drum, mounted between the device for assembling frames and the device for assembling belt-tread bracelets and molding perpendicular to their longitudinal axes, means for transporting parts and frames for radial tires within the installation, according to the invention, means for storing and feeding parts the frame and the bracelet and the means for feeding the tread blanks to the drum are mounted on a common movable bed, the means for feeding the blanks protect The ora from the drive to the means of feeding them to the drum is made in the form of a transporting blank of the tread of an organ moving along a guide located above the means of storage and supply of tire parts to assembly drums. Means for transporting radial tire carcasses are made in the form of a closed chain conveyor with suspensions. A device for assembling the belt-tread bracelets and forming the assembled frame is mounted on a common basis. The store of blanks of protectors is made with the possibility of quick replacement with a new one.

 In FIG. 1 shows a general view of the installation in plan; in FIG. 2, view A in FIG. one; in FIG. 3 view B in FIG. one.

 The installation includes a device 1 for assembling tires of diagonal construction or carcasses of type “P” tires, a device 2 for assembling belt-tread bracelets and forming carcasses of type “P” tires, means 3 for storing and supplying carcass parts to the assembly drum, means 4 for storing and feeding belt parts for a bracelet; means 5 (roller table) for feeding the tread blanks or the running part of the tread to the assembly drum, a mobile drive 6 of the tread blanks or the running part of the tread, means 7 for transferring (transferring) the tread blanks from the drive 6 to the roller table 5, the device 8 for removing the assembled tire or carcass with the drum of the device 1, the means 9 for transferring the belt-tread bracelets between the drums of the device 2, the means for transporting the frames of the radial tires between the devices 1 and 2 in the form of a closed chain conveyor 10 with pendants 11.

 The tire assembly device 1 includes a replaceable assembly drum 12 for assembling tire frames of either diagonal construction or type “P”, patterns 13 and 14.

 The device 2 contains a drum 15 for assembling the belt-tread bracelets and a drum 16 for forming radial frames. The drums are mounted on a common axis.

 Means 3, 4 and 5 are mounted between devices 1 and 2 perpendicular to their longitudinal axes on a common frame 17, which can be moved along devices 1 and 2 using a drive (not shown).

 Installation works as follows.

 Assume that diagonal tires are assembled at the installation. In this case, all the assembly work is carried out on the device 1. The collector takes the tape parts of the frame one by one from the tool 3, which is installed opposite the drum 12. At this time, the carrier 7 takes the next tread blank on the drive 6 and puts it on the rolling table 5.

 Upon completion of the assembly of the frame, before applying the bracelet part, the frame 17 along with the means 3, 4 and 5 moves along the drum 12 to the left until the means 4 and 5 stand opposite the drum. After that, the collector takes the breaker parts from means 4 and puts them on the frame. Then he takes a tread blank from the rolling table 5. When the assembly ends, the assembly tire is pressed and removed from the drum 12 by means 8.

 When type “P” tires are assembled, device 2 comes into operation, and means 4 and 5 are tuned to service this device. The assembly is carried out simultaneously on devices 1 and 2. On the device 1 using the means 3, which is installed opposite the drum 12, the frames of the radial tires are assembled. On the drum 15 with the help of means 4 and the rolling table 5, which are installed opposite the drum, belt-tread bracelets are assembled. In this case, the carrier takes from the drive 6, which is made mobile, that is, mobile in the workshop, to the tread blanks, and the blanks of the running part of the tread.

 The frames assembled on the device 1, removed from the drum 12, are hung by the collector on the suspensions 11 of the conveyor 10 and then fed to the device 2. The assembler working on it removes the next frame from the suspension 11 and puts it on the forming drum 16. Before that, the carrier 9 has moved onto drum 15 and received from it a belt-tread bracelet assembled before it and then transferred it to drum 16. The latter, in the process of forming the skeleton put on it, matches it with the bracelet.

 After completion of the molding and assembly of the tire, it is removed from the drum 16 by the device 9 and then fed to the vulcanization. The cycle ends.

 Thus, thanks to this design of the installation, in which the storage and supply devices for tire parts are made universally transformable, i.e. capable of storing and delivering to the assemblers the nomenclature of parts used in tires of type “D” and type “P”, as well as for each of the assembly devices, either simultaneously or separately: both assembly devices are interconnected by a transport system, which is also the custodian of the stock of frames, there is a mobile a drive for protectors or their running parts, which can be quickly replaced with a new one, provides a wide universality of the installation, its high flexibility with a relatively small footprint.
