Description

TO RETA OF TWO DRUMS FOR RING ASSEMBLY Turrets have been designed which have two drums for tire building machines hitherto to provide for the set of rim components and perform other rim construction operations in two different positions. When the drums have been rotated 180 degrees from a first position to a second position, a deep well has been required in the soil so that the drums are at an appropriate height above the floor to perform manual assembly operations. tire. When the drum trees have been coaxial, a reinforced turret construction has been required to support the weight of the drums that are to carry substantial adrests from the axis of rotation of the turret determined by the length of the trees. drum. Until now, the rotation of the turret, including the drums and auxiliary equipment has stopped when the drive motor has stopped. The turret was then held in position by braking handles propelled toward engagement with slots in a disk connected to the shaft that rotates the turret. There were no provisions to uncouple the engine turret to stop the turret if the engine does not stop. This and important when turntable rotating parts can weigh as much as 2,721.60 ilosgrams. In accordance with the present invention, there is provided a two-drum turret having revolving drums with deviating parallel axes. With this construction, the length of the trees supporting the drums is reduced to a minimum so that a compact turret of minimum weight can be used to support the drums. Also the deflected drums provide means for positioning one of the drums at a lower height than the other drum which is desirable for the operator to move to the drum in the lower position. Security features are also incorporated into the turret if you have excessive turret travel, the drive pinion of the motor will be uncoupled from the semi-circular gear rack and the turret will be stopped by a shock absorber. With the deviated two-shaft turret of this invention, the depth of the well in the ground is reduced to a minimum and different working positions of the drum height are made possible for increased efficiency. In accordance with one aspect of the invention, there is provided a rim construction apparatus comprising a rotating -turn around a turret shaft, a first drum extending outward from a first side of the turret and rotating around a first axis, a second drum extending outward from a second side of the turret and setting around a second axis parallel to and spaced from the first axis and means for rotating the turret to move the first drum from a first position at a first height to a second position at a second height and moving the second drum from the second position to the first position providing access to the first drum and second drum by an operator at a first height Will give ripple component and at a height lower above a floor surface. In accordance with another aspect of the invention, there is provided a method of assembling rim components in a turret that comprises: (a) applying the initial rim components in a first turret-mounted drum in a first position having a first height above a floor surface, (b) rotating the turret to transfer the first drum and rim components to a second position at a-second height above the floor surface, (c) simultaneously with the application of the additional rim components in the first drum in the second position, apply the rim components in a second drum mounted in turret in the first position; and (d) separating the rim assembly from the first drum. To relate to persons experienced in the techniques most closely related to the present invention, a certain preferred embodiment of the present invention is described herein which illustrates a better mode now contemplated for putting the invention into practice, by and with reference to the attached drawings that are part of the specification. The embodiment shown and described herein is illustrative and as will be apparent to those experienced in these branches, may be modified in many ways within the scope of the invention defined in the claims herein. in the Drawings Figure 1 is a front elevation of a two-drum turret assembly that odalizes the invention. Figure 2 is a side elevation of the tether assembly, taken along line 2-2 in Figure 1 with the drums removed. Figure 3 is a rear elevation of the turret assembly, taken along line 3-3 in Figure 2 with legs being broken. Figure 4 is a fragmentary top view of the tire, taken along the line 4-4 in Figure 1. With reference to Figures 1, 2 and 3, a base 10 mounted on a surface 12 of floor and fastened to a turret support housing 14 by bolts 16 or other appropriate fasteners. Bearings 18 are mounted on the housing 14 which provide bearings to support a turret drive shaft 20. A turret 22 is mounted on an exterior of the shaft 20 and includes a turret support plate 24. Referring to Figures 1 and 4, a Drum tam bor 26 is rotatably mounted on the turret support plate 24 and extends outwardly from a first side 28 of the turret 22 for rotation about an axis AA in a first position X. The Drum Drum 26 is also known as the satellite tam and is mounted on a satellite shaft 30 rotatably supported on a satellite bearing 32 mounted on the support plate 24. A satellite drum drive motor 34 is also mounted on the support plate 24 and is in a driving relationship with the satellite shaft 30 through a satellite band 36 extending around the pulleys mounted on the satellite shaft 30. and the sa.t? lite motor drive motor shaft 34. Mounted on the second side 38 of the turret 22 is a second drum 40 of rim construction rotatable about a second axis BB in a second position Y. The second drum 40 of rim construction is also known as the drum The master is mounted on a master shaft 42 supported on a master bearing 44 mounted on the support plate 24. The master shaft is driven by the other master drum drive 46 mounted on the support plate 24 and connected by a master band 48 to the master shaft through drive pulleys. As shown in Figure 1, the axis AA of the first drum 26 and the axle BB of the second drum 40 are in parallel relation so that in the operating position the first drum 26 is at a first height 50 of about 101.6. cms. Dor above the floor surface 12 which is less than a second - height 52 of approximately 127 centimeters from the second drum -40 above the floor surface. This is important when manual operations are required to apply the rim components to the drum 26, the drums 26 and 40 need to be close to the floor surface 12 so that the operator can reach the drums. In addition to the axes AA and BB which are parallel, the turret construction provides for the deviation of the satellite shaft 30 from the master shaft 42 which minimizes the distance of the first drum 26 and the second drum 24 extend outward from the first side 28 and second side 38 of the turret. This configuration reduces the space required to rotate the turret 22 and the depth of a well 54 necessary to allow rotation of the turret around the axis of the turret drive shaft 20. It is important for the effective operation of the two-drum turret assembly of this invention that the first tambour 26 and the second drum 40 have axes A-A and B-B that are symmetrical about the axis C-C of the turret drive shaft 20. In accordance with the invention, the master bearing 44 is mounted on the support plate 24 in a predetermined position. This is achieved by driving the edges of the master bearing 44 with the registers 55 and 56 in the plate 24 with screw screws 57 threaded into the plate. Then the position of the satellite bearing 32 is adjusted by the adjusting screws 58 and screwed on the plate 24 so that the axis AA of the first drum 26 is parallel with the axis BB of the second drum 40 as well as being symmetrical about the axis CC of the turret drive shaft 20. With this setting, the first drum 26 and the second drum 40 will be in identical positions when the first position X and the second position Y so that the rim components applied to the drums are applied in identical positions regardless of which drum is in a particular position. Referring to Figures 2 and 3, a drive gear -60 is mounted on the rear end of the turret drive shaft 20. The drive gear 60 has a semicircular gear grid 61 engageable with a pinion gear 62 driven by a turret drive motor 63 mounted in the housing 14. Referring to Figure 3, the drive gear 60 is rotated. from the position shown in Fig. 3 in a clockwise direction 180 Q so that the turret support plate 24 as shown in Fig. 1 will rotate 180 Q in a left-handed direction by moving the first drum 26 from the first position X shown in Figure 1 a - the second position Y shown in Figure 1 and moving the second drum 40 from the second position Y shown in Figure 1 to the first position X shown in Figure 1. In the two positions X and Y of operation, a cam roller 64 driven by a clamp y and pneumatic extends towards a tapered slot or slot 70 in the operating positions of the turret 22 to hold the turret in a position operation. In case the motor 63 does not stop to allow actuation of the cam roller 64 by the fastener 66 - pneumatic, the length of the semicircular gear rack 61 is predetermined to disengage the pinion 60 after which the shaft 20 it will continue to rotate and the arm 72 mounted on the shaft and extending outwardly therefrom is positioned to engage the dampers 74 mounted on the housing 14. One of the dampers 74 is provided on each side of the housing 14 to limit rotation of the turntable support plate 24 in any direction by engagement with the arm 72. In a typical tire construction operation, the Duede rim components are applied to the first drum 26 and the second drum 40 by rotating the drums through the drum. drive of the satellite drum drive motor 34 and the master drum drive motor 3 in response to appropriate controls connected to the motor is. After application of the rim components the cam roller 64 can be lively and the turret drive motor 63 driven in response to appropriate controls to rotate the turret 22 in 1805 by which the first drum 26 moves to the second position Y and the second drum 40 moves to the first position X as shown in Figure 1. Simultaneously with the application of additional rim component in the first drum 26 in the second DOSE Y in the second height 52 , the rim components can be provided in the second drum 40 of rim construction in the first position X as shown in Figure 1. It is understood that the first drum 26 and the second drum 40 are identical, however, they can replace different drum sizes and types by these drums and be adaptable for different rim construction operations. While a certain embodiment and representative details have been shown for the purpose of illustrating the invention, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the scope of the invention.
