Description

The invention relates to the production of pneumatic tires and can be used in the tire industry, in particular for assembling radial tires, as well as for diagonal tires.

The known line for assembling frame bracelets for tires of pneumatic tires is auth. No, containing a rotary rotor with assembly drums mounted on it by means of shafts, a device for supplying and superimposing frame bracelets, devices for transferring blanks and actuators for rotating the rotor and for rotating the assembly drums, where the shafts of the assembly drums are located tangentially relative to the rotary rotor .

The disadvantage of this line is that the movement of transport devices for the removal of collected

frame bracelets on monorails located above the devices for supplying and overlaying the workpieces make it difficult to maintain the latter, require the use of specialized fencing devices and lengthen the transport routes of the assembled frame bracelets.

In addition, the constant positioning (permanently selected) of the assembly drums on the rotary rotor during its operation complicates the arrangement of such a line with the line of the final assembly of tires and limits its versatility.

The aim of the invention is to improve the conditions of service and operation of the device for feeding, laying and transferring the frame bracelets blanks.

This goal is achieved by the fact that the lines for assembling tire bracelets for tires of pneumatic tires are equipped with rotary faceplates mounted on the rotor with rotational drive drives, and assembly drum shafts are mounted on faceplates. The axes of the rotary faceplates are mounted parallel to the axis of rotation of the rotor. FIG. 1 shows a line, a view in plan) in FIG. 2 - the same, a side view (conventionally, two assembly drums are shown and feeding carriages are not shown) in FIG. 3 - the same, end view of one of the drums (the remaining drums are conventionally not shown), in FIG. - section aa in figure 1; in fig. 5 is a view of the mechanism for rotating the faceplate; in Fig. 6 is a top view in Fig. 55 in Fig. 7-1; 15 is a longitudinal section of a bracelet assembled on a line. The line for assembling frame bracelets contains a rotary rotor 1 (Figures 1 and 2) mounted on platform 2 and equipped, for example, with ten assembly drums 3, each of which is mounted on shaft k. The shafts are installed in bearings bearing fixed to rotary faceplates 5, which are mounted with their axes 6 (figure 4). by means of bearings 7-9 on the rotor 1, to rotate the faceplate 5 on the platform 2, a rotation mechanism is mounted, made in the form of an L-shaped lever 10 (fig. 5.6) pivotally connected to the pneumatic cylinder rod 11 and interacting with the roller 12 , zip on platform 2 and bracket 13 of faceplate 5. Return of faceplate 5 to its original position is carried out by means of, for example, tension or torsion springs, fixing faceplate 5 in two positions by means of fixator 14 mounted on rotor 1. Axis of the p-shanshib 5 mounted on parallel to the axis of rotation of the rotor 1. The line is equipped with devices 15 (Fig. 2, 3) for feeding blanks, fed by transport carriages 1b with cord blanks and details of the frame to be assembled. The rotor 1 is equipped with a rotation drive 17 and drives for rotating the assembly drums 3. The devices 15 are provided with a lifting table 19, which is moved relative to the drum 3 by means of a drive 20. A drive 22 is mounted in the frame 21 to raise the table 19. The carriages 1b at work positions interact with the drives 23 for rolling stock material from carriage reels. For the transfer of the workpiece 2k through the first transport carriage, for example, a roller conveyor 25 is installed. I will remove the assembled bracelet from the assembly side. The main drum 3 of the rotor 1 at the pickup position and transferring it to the device for final assembly of tires of pneumatic tires can be carried out using the device 2b, which can be moved, for example, along the monorail 27. For example, the line has ten positions, one of which serves to remove the assembled bracelet. If necessary, the number of positions for the removal of the collected bracelets may be more, for example two. At the same time, these positions are redundant with an increase in the number of parts in the bracelet at these positions it is also possible to carry out the imposition of parts. Lini works as follows. The manufacture of the skeleton bracelet begins when the assembly drums 3 are fixed above the devices 15. Thereafter, the actuator 22 is turned on to lift the table 19 until it contacts the assembly drum 3, then the drives 18 and 20 are turned on and the drum 3 rotates and the table 19 moves. At the same time, the end of the blank is held on the drum 3. The blank is transferred from the table 19 to the drum 3 and the first layer of the bracelet is formed. In this case, the first layer is the sides 28 (Fig. 7). After the first operation, the rotor 1 is turned. Assembly bararan 3 moves to the second position where overlapping side strips 29 are applied (Fig. 8). In the next position they impose side metal cord tapes 30 (Fig. 9), in the fourth position they impose tapes of monofilament 31 (Fig. 10), on the fifth sealing layer 31 (Fig. 11), on the sixth layer - cord 33 (Fig. 12 ), on the seventh - the second layer of cord 3 (FIG. 13, on the eighth and ninth shaped sections of the breaker 35 (FIG. 1) .. o) The result is a “frame bracelet Zb (FIG. 15), which is removed from the assembly drum 3 For example, at position ten by means of device 2b. Before removing the bracelet 36, at position ten, the faceplate 5 is turned The left corner and the shaft 4 with the assembly drum 3 are installed radially with respect to the rotor 1. The rotation of the faceplate 5 is carried out after turning and fixing the rotor 1 by turning on the pneumatic cylinder 11 (Fig. 5.6), which moves the L-shaped lever 10 along the roller 12 and sets it in a horizontal position (the initial and "intermediate position of the lever 10 in Fig. 5. are shown in dashed lines). The lever 10 interacts with the bracket 13 and rotates the faceplate 5 to the desired angle. Then include latch I, which fixes the faceplate 5 in this position. The pneumatic cylinder 11 is switched to reverse, returning the L-shaped lever 10 to its original position. After removing the strap bracelet, drum 3 is returned to its original position, i.e. again positioned tangentially with respect to the rotary rotor 1. The return of the drum 3 to its initial position is carried out either at the static position of the rotor 1, or at the time of its rotation after deactivating the latch 1 when the faceplate 3 returns to its initial position by spring force. The proposed line design for assembling frame bracelets while ensuring the assembly of multilayer bracelets makes it possible to expand the possibilities of using such devices by making it more versatile, improves service conditions, reduces the production area by improving the layout of both the device and other devices for final assembly. tires pneumatic tires.
