Description

SURFACE WINDING ON AN A-FRAME WINDER
Technical Field
This invention relates to winding a strip of sheet material such as a tire component on a spool which is transported to a tire building machine for building a tire. The spool may be mounted on a cart which also supports a liner shell for a liner which is interposed between the material wrapped around the wind-up shell of the spool of material. Background Art
Server systems, such as that shown in U.S. Patent No. 4,951,892 for storing and delivering stock material are used in the tire manufacturing process. The handling, storage and transporting of the tire components on a spool mounted on an A-frame cart has obvious convenience advantages. There are also disadvantages such as the distortion of the material during winding on the spool. This is particularly true in winding a tread, where the contours of the tread are important and may be distorted in the winding- storage process. Belts that are wound on a spool may also be distorted and the ends-per-inch count of the wires in the belt may be altered such that the stored belt does not meet specifications and must be rejected. Also because the components are wound with a liner separating the layers, it has been found that the "square woven" components may be crushed and separation from the liner becomes difficult, if not impossible. Where calendered material is wound on the spool it may be distorted and flattened at the center of the roll and may have to be cut away from the liner, wasting expensive liner material and delaying the manufacturing process. These problems are believed to be due in part to the distortion caused by undue pressure applied in the wind up and storage process. Heretofore, center driven winders have been used to wind the spool by a motor which rotates a shaft connected to the wind-up shell of the spool. Winding tension control for applying and varying the tension applied to the component being wound on the spool is important because it must be varied as the spool grows in size and diameter during wind up.
Surface winders have also been used in some cases wherein the component is wound through contact with the surface of the spool by a moving belt. With traditional surface winders the spool is supported on a driving belt and the weight of the spool distorts the material unless an adjustable support is provided to lift the spool and take the weight off the driving belt. This is not desirable because the entire weight of the spool must be carried by the adjusting means.
In accordance with one aspect of the invention there is provided apparatus for winding a strip of sheet material on a rotatable spool of sheet material comprising a surface winder having belt means movable into engagement with the strip of sheet material for application to the spool and for rotating the spool characterized by pressure means for moving the surface winder and the belt means toward the spool to urge the strip of sheet material against the spool, and belt drive means engageable with the belt means for delivering the strip of sheet material to the spool and rotating the spool to wind the strip of sheet material on the spool. In accordance with another aspect of the invention, there is provided a method of winding a strip of sheet material on a rotatable spool comprising:
(a) conveying the strip of sheet material on a belt to a surface winder at the spool; characterized by
(b) urging the surface winder and the belt toward the spool to press the strip of material against the spool; and
(c) driving the belt to wind the strip of sheet material on the spool and to rotate the spool.

Fig. 4 is an end view like Fig. 1 showing the apparatus with the surface winder retracted for cart removal. Detailed Description of the Invention
Referring to Figs. 1, 2 and 3, a wind-up apparatus 10 is shown having a movable cart frame 12, supported on a floor by wheels 11, for transporting a spool 14 of sheet material 16 from a wind-up position, such as that shown in the drawings, to a delivery or server position spaced from the wind-up position. Where the sheet material 16 is a tire component, such as a tread or ply, the sheet material may be conveyed to the wind-up position on a belt conveyor 18, where it is carried on a belt 20 to a position spaced from a sheet material applier frame 22 positioned adjacent to the movable cart frame 12.
The sheet material applier frame 22 has side plates 24 and 26 supporting a driving pulley
28 driven by a motor 30 , or other driving means for driving a driving belt 32. The driving belt 32 is trained around the driving pulley 28, a take-up pulley 34 and a pair of spaced pulleys 36 and 38 of a surface winder 40. The take-up pulley 34, may be mounted on pressure controlled air cylinders 35,35 fastened to each of the side plates 24 and 26 with the weight of the take-up pulley and the pressure controlled air cylinders maintaining the driving belt 32 in tension.
The surface winder 40 has a pressure means such as a pair of piston cylinder assemblies 43 and 44 fastened to the side plate 24 and side plate 26 of the applier frame. The piston cylinder assemblies 43 and 44 have piston rods 47 and 48 attached to mounting plates 50 and 52 spaced apart and positioned at opposite ends of the spaced pulley 36 and spaced pulley 38 of the surface winder 40. The piston rods 47 and 48 are pivotally mounted to the mounting plate 50 and mounting plate 52 whereby the spaced pulley 36 and spaced pulley 38 are radially movable to conform to the contour of the spool 14. Movement of the surface winder 40 towards the spool 14 is provided by the piston-cylinder assemblies 43 and 44.
The movable cart frame 12 of the wind-up apparatus 10 may have spaced bearings 58 and 60 for rotatably supporting a shaft 62 of a wind-up shell 64. Liner support arms 66 are mounted on the movable frame 12 and extend to a spaced apart position for supporting a liner shell 68 of a liner roll 69 in bearing 70. Also supported on the floor are liner support members 71 attached to the movable cart frame at either side thereof for supporting a lead in roller 72, precision guide
74 and a lead out roller 76.
The wind-up apparatus 10 shown in Fig. 3 illustrates the apparatus with the spool 14 at the end of the wind-up operation.
The wind-up apparatus 10 shown in Fig. 4 illustrates the apparatus with the spool 14 after the sheet material 16 and a liner 78 have been wrapped in a spool which may be transported to another location for delivering the sheet material or for storage. The location where the movable cart frame 12 is located, as shown in the drawings, is then open and available for another movable cart frame to be parked, and another spool wound up on an apparatus like that shown in Figs. 1, 2 and 3. In operation, the diameter of the spool 14 at the beginning of the wind-up operation is the diameter of the wind-up shell 64 as shown in Figs. 1 and 2. The diameter of the liner roll 69 on the liner shell 68 is substantially greater than that shown in Fig. 1, but with the outer diameter spaced from the wind-up shell 64. The surface winder 40 maintains contact with the spool 14, as shown in Fig. 1, so that the spaced pulleys 36 and 38 urge the sheet material 16 on the driving belt 32 against the sheet material into contact with the liner 78 and rotate the spool 14 in a clockwise direction R, as shown in Fig. 1. The pivotal mounting of the spaced pulleys on the mounting plates 50 and 52 cause the driving belt 32 to conform with the surface of the spool 14 pressing the material 16 against the surface and at the same time, driving the spool in a clockwise direction. In this condition, the take-up pulley 34 is in a raised position as shown in Fig. 1.
As shown in the drawings, the driving belt 32 not only carries the sheet material 16 to the spool 14, but also remains in contact with the sheet material as it is applied to the spool. This provides the desired friction for mrning the spool 14 with a controlled pressure from the piston- cylinder assemblies 43 and 44. The liner 78, which has one end wrapped around the spool 14, is pulled from the liner shell 68 over the lead in roller 72 through the precision guides 74 and over the lead out roller 76 so that it will be positioned accurately on the spool 14.
The conveyor 18, which may convey the sheet material 16 from a suitable source, such as an extruder or calender, may be driven by a separate drive and a festoon 80 is preferably provided between the conveyor belt 20 and the driving belt 32 to accommodate differences in the rate at which the sheet material is supplied by the conveyor 18 and the rate it is applied to the spool 14 by the driving belt 32. These differences in speed may be determined by the position of the festoon 80 as registered by photo eyes 82 and 84. The driving speed of the motor 30 connected to the driving pulley 28 and the driving speed of the motor for the conveyor 18 may then be adjusted accordingly.
While certain representative embodiments and 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. Having thus described the invention, it is now claimed:
