Description
Device for ply-tread case transportation in radial tyre manufacturing Technical field
The invention relates to a device for transportation of a ply-tread case utilized in a building line when manufacturing radial tyres, wherein transportation is carried out by means of an annular ring having fastening segments, which fix the transported ply-tread case in a required position.
Background art
During the manufacturing process of radial tyres a ply-tread case is transported from a ply-tread drum over a steel-belt or building drum, where a steel-belt case is formed and subsequently connected with the ply-tread case.
The ply-tread case typically consists of a plurality of steel-carcass plies, a spiral ply and a tread wound up on a ply-tread drum. After winding up the respective components the ply-tread case is fastened by means of transportation device segments after transporting the ply-tread case transportation device over the ply- tread drum. Subsequently, after gripping the ply-tread drum, transportation of the case by the ply-tread case transportation device occurs. After transportation of the ply-tread case over the building drum the carcass case is formed and the carcass case is connected with the ply-tread case. Subsequently, the ply-tread case is released in the transportation device and transportation device is displaced so that the required space is cleared for bringing up the stitching rollers. The connecting of individual tyre layers occurs by final rotation of the building drum at simultaneous pressing of the stitching rollers. Since the entire process of ply-tread case transportation, forming and stitching of a tyre is a sequencing process, it can sum up to presence of idle time having a negative impact on the resulting time cycle of the building line. If the time losses are eliminated by positioning the segments fixing the ply-tread case so that a
space for bringing up the stitching rollers is created, the significantly negative effect occurs in the uniformity of manufactured tyres.
Up to the date the known devices for ply-tread case transportation in the building process have consisted of an annular ring having circumferential ly positioned segments holding the ply-tread case described in document US2012256434 (A1 ). Movement of the segments in the radial direction is provided by separate actuators having brakes or alternatively the segments are mechanically coupled and their radial movement or the movement along the trajectory are centrally controlled. Their own holding segments may be positioned symmetrically or alternatively with a slight asymmetry.
The advantage of said system is a sufficient amount of segments fixing the ply- tread case; the disadvantage is the necessary relocation of the transportation device prior to the supply of stitching rollers, thereby increasing the cycle time of the building line.
Another known devices for the ply-tread case transportation in the building process, for example according to document EP 0 880 436 B1 they consist of an irregular annular ring having respective gates or alternatively consist of an asymmetric annular ring having openings necessary for supplying stitching rollers. Optimal positioning of the holding segments is thereby disrupted causing the ply- tread case being insufficiently held and subsequently, its deformation may occur. Improvement of cycle time is an advantage of this system, the disadvantage being an insufficient number of segments holding the ply-tread case having a significantly negative effect on uniformity of the manufactured tyres.
It is an objective of the present invention to provide a device for the ply-tread case transportation in the building process, which would fail to have a negative effect on uniformity of manufactured tyres. Accordingly, the task is to provide the device for ply-tread case transportation, where the ply-tread case is transported by a system of optimally positioned holding segments and simultaneously the down time slots are eliminated and thus the cycle time of the building line is improved.
Summary of the invention
The aforementioned drawbacks of the device in the state of the art for the ply- tread case transportation in the building process of radial tyre manufacturing are eliminated by the device according to the present invention. The device according to the invention contains a ring for ply-tread case transportation and a means of transportation thereof. The ring consists of two firmly connected portions, namely of an incomplete annular frame and a bracing frame shaped similarly to a horizontal letter U. The bracing frame provides for the ring stiffness and consists of two horizontal arms connected by a vertical part, while the horizontal arms are arranged perpendicularly to a vertical plane A-A and the vertical portion is parallel thereto. Thus, the bracing frame is formed outside the vertical plane A-A. In other words, the bracing frame enjoys a shape similar to the horizontal letter U, where the free ends of the bracing frame are connected to the free ends of the incomplete annular frame perpendicularly to the vertical plane A-A, wherein the bracing frame complements the incomplete annular frame to a ring from the perspective perpendicular to the plane A-A. The ring has spaced apart segments holding the ply-tread case in regular intervals along the inner circumference. Said segments are symmetrically positioned with respect to a central vertical plane B-B passing through the ring.
The central vertical plane B-B is understood to be the vertical plane dividing the ring into two semi-rings. The vertical plane A-A is understood to be the vertical plane getting along the entire circumference of the incomplete annular frame in the midst of its thickness dividing said frame into two incomplete frames of a half thickness. Transportation of the ply-tread case over the building drum, the carcass case of the manufactured radial tyre is located thereon, is carried out by means of the ring positioned on the inner circumference provided with at minimum 6 holding segments arranged radially displaceably on said ring. Wherein, at minimum one
holding segment is positioned on the bracing frame and other holding segments are positioned on the incomplete annular frame. The holding segment positioned on the bracing frame additionally enjoys a possibility of separate axial displacement from the base position. The base position of said holding segment is the operational position, wherein the holding segment is positioned in the plane A- A. The holding segment is displaceable along the horizontal arms of the bracing frame into the holding-off position. Displacement of said holding segment in axial direction is provided by a separate actuator. Instead of one holding segment, the incomplete annular frame may contain a central stitching roller. The central stitching roller is positioned in the bottom part of the ring at the point of passing the central vertical plane B-B and it simultaneously performs the function of the holding segment, since it is also positioned radially displaceable. The radial displaceable positioning of the central stitching roller enables the radial displacement from the base position when performing the function of the holding segment and into the telescopic position when performing the function of the central stitching roller. The advantage of said configuration lies in the fact that immediately after releasing the standard holding segments the drum starts spinning and the central part of the tread is being stitched, thus time required for moving said stitching roller forward is eliminated.
A space for moving the stitching rollers forward serving in particular for stitching side walls of the tyre is formed even during stitching operation of the central part of the tyre by the central stitching roller by means of moving away the respective segment. Thereby, the negative impact on uniformity of manufactured tyres is eliminated, since the ply-tread case is optimally held during its transportation and cycle time of the building line is not increased.
Distribution of standard holding segments on the circumference of the ring with respect to the position of the central stitching roller in the bottom position is determined by optimization respecting the vertical position of the ply-tread case, its stiffness and weight, for example based on the finite element method (Finite Element Method) so that the maximum uniformity of manufactured tyres is
maintained. Displacement of standard holding segments and the central stitching roller in radial direction so as to enable holding and releasing the ply-tread cases is performed by separate actuators. Displacement of the ply-tread case transportation device between the building drums is carried out along a bearing or alternatively along a gantry of the building line by means of a transporter.
The ring may be provided with at least two arms arranged perpendicularly to the vertical plane A-A. Each arm is provided with an accessory holding segment. Said accessory holding segments serve the purpose of holding, transportation and release of the manufactured tyre.

Detailed description of the invention
The device for transportation of the ply-tread case 3 used in radial tyre manufacturing according to Figs. 1 a and 1 b consists of a vertically positioned ring 1, positioned on transportation means 5 in the form of a transporter. Ring 1 consists of two constituent part, namely of an incomplete annular frame l a and of bracing frame 1_b, fixed perpendicularly on the incomplete annular frame 1_a and complementing the incomplete annular frame l a into ring 1 from the perspective in the direction of the central axis of ring 1 Said bracing frame 1_b consists of two equally long horizontal portions, connected by the vertical part, protruding from the ends of the incomplete annular frame l a perpendicularly to the vertical plane A-A.
Along the inner circumference of the incomplete annular frame l a there are regularly spaced 9 radial moveably arranged holding segments 2J_ to 29, for holding, transportation and release of the ply-tread case 3.
Bracing frame 1_b is provided with holding segment 20, so as to complement holding segments 21_ to 29. Holding segments 20 to 29 are spaced at regular intervals and symmetrically with respect to the central vertical plane B-B. Holding segment 20 is transversally axially displaceable with respect to the vertical plane A-A from the base position to the holding position along the horizontal arms of bracing frame 1_b by means of a respective actuator to make space for moving stitching rollers 9J_ and 92 forward.
The central stitching roller 4 that simultaneously fulfils the function of the holding segment is positioned at the bottom part of ring 1 at the point of passing the central vertical plane B-B.
Ring 1 is attached to a transporter. The transporter provides for the movement of ring 1 and thus transportation of the ply-tread case 3 between building drums and transportation of manufactured tyre 10 to an unloading position.
Ring 1 is provided with two arms. Each arm carries one accessory holding segment 61, 62. Said accessory holding segments 6J_, 62 serve for holding the manufactured tyre, release thereof from building drum Y\_ and transportation for further treatment.
The carcass case is formed on building drum 1J_. The carcass case is connected with the ply-tread case 3 held in ring 1 by holding segments 20 to 29. Subsequently, holding segments 20 to 29 release the ply-tread case 3, as depicted in Fig. 2. Subsequently, holding segment 20 is displaced from the base position into the holding position as shown in Fig. 3.
Immediately after releasing the ply-tread case 3 the phase of spinning of building drum and instant stitching by the central stitching roller 4_ensues. Space for moving stitching rollers 9 and 92 forward was formed by releasing and subsequent axial displacement of holding segment 20 to the holding position. Said stitching rollers 91, 92 serve in particular for rolling sidewalls of the ply-tread case 3 already during rolling the central part of the ply-tread case 3 by the central stitching roller 4, as shown in Fig. 4.
After completion of stitching of the central part of the ply-tread case 3 and after returning the central stitching roller 4 into the base position, axial displacement of stitching rollers 9J_ and 92 from each other continues, as shown in Fig. 5.
Immediately after returning the central stitching roller 4 into the base position the entire ply-tread case transportation device is displaced beyond A-A axis, according to Fig. 6 so as to form sufficient space for axial displacement of stitching rollers 91 and 92 required for completion of the stitching process.
Subsequently, according to Fig. 7 completed tyre 10 is held by accessory segments 61 and 62 and it is displaced into the unloading position after being released by the building drum 1J_. Simultaneously, the axially displaceable segment 20 is returned into the base position by the respective actuator.
