Abstract
A device and a method for storing an elongated plastically deformable member are provided in which, even if an elongated plastically deformable member and a liner are stored in a state of being superposed together and wound on a take-up reel, deformation of portions of the elongated plastically deformable member and non-uniformity of deformation of the elongated plastically deformable member can be suppressed. When a liner and an unvulcanized tread member are taken-up on and stored on a reel, the reel is supported by a driven roller and a drive roller, and the reel is stored in a state of being rotated constantly. As a result, during storage, a load caused by the wound tread member itself is applied uniformly to an entire wound circumference. Therefore, collapsing deformation caused thereby is made uniform along a longitudinal direction, and differences in a configuration of the tread member at respective wound layers do not arise.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a device and a method for storing an elongated plastically deformable member which use a take-up reel on which an elongated plastically deformable member is taken-up in a state of being superposed together with a liner.




2. Description of the Related Art




Conventionally, in order to store unvulcanized, green rubber used for the tread or the sidewalls or the like of a tire, there are methods in which an elongated green rubber member, which is extruded from an extruder and has a constant cross-sectional configuration, is stored in a state of being taken-up (wound) on a reel.




At this time, because the green rubber is tacky, if it is taken-up as is, the outer side of one layer of the wound green rubber sticks to the inner side of another layer of the wound green rubber.




As a result, generally, the green rubber member extruded from the extruder is taken-up in layers via a liner. That is, the liner is disposed between the respective wound layers of the green rubber, which prevents the layers from sticking to one another.




Generally, because an unvulcanized, green rubber is plastic, it tends to deform when mechanical stress is applied thereto. When the green rubber is taken-up together with the liner, the configuration of the green rubber deforms due to the tension of the liner and the weight of the green rubber itself.




In particular, the deformation caused by the weight of the green rubber itself which is rolled in layers is great. Such deformation in the green rubber causes troubles in molding in a later process, and the uniformity of obtained products is markedly poor.




Thus, as illustrated in

FIG. 15

, an elongated member storing device has been proposed in which a spacer


102


is mounted to and integral with either end of a liner


103


. A space d is formed between the outer side portion of a green rubber member


101


, which is taken-up onto the reel via the liner


103


, and the inner side portion of the liner


103


, so as to prevent deformation of the green rubber member


101


.




Further as illustrated in

FIG. 16

, an elongated member storing device has been proposed in which receiving members


204


,


205


are provided, along a swirled line having a standard interval k around a center axis C of the reel, at opposing sides of a pair of opposing rotating members


202


,


203


. Due to the receiving members


204


,


205


, an elongated member


201


is wound via a liner


206


, and a space d is formed between the outer side portion of the wound elongated member


201


and the inner side portion of the liner


206


. In this way, plastic deformation of the green rubber product can be prevented.




In the device in which the spacers


102


are made integral at the both ends of the liner


103


(see

FIG. 15

) and the device provided with the pair of receiving members


204


,


205


disposed along a swirled line having standard intervals between respective wound layers (see FIG.


16


), plastic deformation of the green rubber product is prevented due to the space d being formed between the outer side portion of the wound elongated product and the inner side portion of the liner.




There are green rubber products of various different thicknesses, and thus, in the above-described storing devices illustrated in

FIGS. 15 and 16

, the spiral interval d is determined on the basis of the thickest green rubber product.




As a result, when a thinner green rubber member is wound, the interval d is large and the wound length of the green rubber member is short, and thus, the winding efficiency is poor.




In order to overcome this problem, a plurality of types of liners


103


whose spacers


102


have different thicknesses may be readied, or a plurality of types of devices having different spiral intervals d may be readied. However, this results in drawbacks such as increased costs and poor efficiency of use.




SUMMARY OF THE INVENTION




In view of the aforementioned, an object of the present invention is to provide a device and a method for storing an elongated plastically deformable member in which, even if an elongated plastically deformable member such as green rubber or the like is stored in a state of being wound in superposed layers, deformation of portions of the elongated plastically deformable member and non-uniform deformation of the elongated plastically deformable member can be suppressed.




In order to achieve the above object, a first aspect of the present invention is a device for use in storing an elongated plastically deformable member wound on a take-up reel with a thin-plate-shaped liner superposed with the elongated plastically deformable member, the take-up reel having an axis which is substantially horizontal, the device comprising a rotating means adapted to rotate the take-up reel at least one of constantly and intermittently.




Further, a method of the present invention for storing an elongated plastically deformable member wound on a take-up reel together with a thin-plate-shaped liner superposed with the elongated plastically deformable member, the take-up reel having an axis which is substantially horizontal, comprises the step of rotating the take-up reel at least one of constantly and intermittently.




In this first aspect of the present invention, when a take-up reel, on whose outer peripheral surface are wound a superposed thin-plate-shaped liner and an elongated plastically deformable member, is set in a state in which the axis of the take-up reel is substantially horizontal with respect to a setting surface, the take-up reel is rotated at least one of constantly or intermittently by the rotating means.




Because the take-up reel is rotated constantly or intermittently, during storing, the load of the wound elongated plastically deformable member itself is applied uniformly to the entire wound circumference and does not concentrate at particular portions, even after time passes. Therefore, collapsing deformation caused thereby is made uniform along the longitudinal direction, and differences in a configuration of the elongated plastically deformable member between the respective wound layers do not arise.




Here, “always rotated” or “constantly rotated” means “continuously rotated”, but may include stopping for an instant such as when reversing rotation (a period of time in which configurational differences which adversely affect the uniformity of the product are not caused between the respective wound layers of the elongated plastically deformable member; this time varies in accordance with the wound amount, the flexibility, and the like of the elongated plastically deformable member).




In a second aspect of the present invention, in the device for use in storing an elongated plastically deformable member according to the first aspect, the rotating means rotates the take-up reel over a given angle in a first direction of rotation, and thereafter, the rotating mechanism rotates the take-up reel in another direction, and alternately repeats rotating in said first direction and said another direction of rotation.




Further, a method of the present invention for storing an elongated plastically deformable member wound on a take-up reel together with a thin-plate-shaped liner superposed with the elongated plastically deformable member, the take-up reel having an axis which is substantially horizontal, comprises the step of rotating the take-up reel at least one of constantly and intermittently.




The member which is being taken-up and stored with the liner is an elongated plastically deformable member such as a green rubber product. An unvulcanized green rubber is plastic, and is easily deformed when mechanical stress is applied thereto. Therefore, if, during storage, the take-up reel is continuously rotated in the same direction as the direction in which the green rubber product is wound, the winding of the wound green rubber product will tighten. If the take-up reel is continuously rotated in the direction opposite the direction in which the green rubber product is wound, the winding of the wound green rubber product will loosen.




In accordance with the present aspect, after the take-up reel is rotated over a given angle, the direction of rotation is changed, and this rotation and changing of the direction of rotation are repeated. Therefore, tightening of the winding or loosening of the winding of the elongated plastically deformable member taken-up on the take-up reel can be prevented.




Here, it is preferable that the given angle is 180° or an integer multiple of 180°.




In a third aspect of the present invention, in the device for storing an elongated plastically deformable member, the rotating means has pair of rollers which abut the take-up reel.




In the present aspect, the take-up reel is disposed on the pair of rollers, and by rotating the rollers, the take-up reel is rotated.




In a fourth aspect, one roller of the pair of rollers is a drive roller connected to a rotating driving means, and the other roller is a driven roller.




In accordance with the present aspect, the drive roller is rotated by the rotating driving means, and the take-up reel is thereby rotated. Due to the rotation of the take-up reel, the driven roller abutting the reel rotates.




In a fifth aspect of the present invention, the driven roller is connected to a moving means, and when the driven roller is moved from a first position to a second position, the take-up reel is raised up off of the setting surface by the driven roller and the drive roller.




In accordance with the present aspect, the driven roller is provided so as to be able to be moved by the moving means. When the driven roller is positioned at the first position, the take-up reel is disposed on the setting surface. As a result, the take-up reel can be loaded in and removed from the device for storing an elongated plastically deformable member by being rolled on the setting surface. At the next stage, when the take-up reel is disposed between the driven roller and the drive roller, the driven roller is moved from the first position to the second position and the take-up reel is raised up off of the setting surface by the driven roller and the drive roller. As a result, the take-up reel is supported and rotated by the driven roller and the drive roller.




In a sixth aspect of the present invention, the driven roller is removably provided.




In accordance with the present aspect, if the driven roller gets in the way when the take-up reel is attached or removed, the driven roller is removed, so that the work of attaching or removing the take-up reel is facilitated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




First Embodiment




A first embodiment of the present invention will be described hereinafter with reference to the drawings.





FIG. 4

is a schematic illustration of, as an example, a tread member take-up device


60


for taking-up an unvulcanized tread member used in manufacturing a tire.




The tread member take-up device


60


includes a conveying belt


64


for conveying an unvulcanized tread member


62


which has been extruded from an extruder (not shown), conveying rollers


66


around which the conveying belt


64


is trained, a roller


70


for supplying a liner


68


which is formed from synthetic resin or the like, and a rotating shaft


74


which supports a reel


72


for taking-up the tread member


62


via the liner


68


.




As illustrated in

FIG. 3

, the reel


72


has a flange


78


at either end of a drum


76


which takes-up the tread member


62


.




The tread member


62


, which is extruded out from the extruder, is conveyed by the conveying belt


64


, and is taken-up by the reel


72


.




At this time, the liner


68


which is wound around the roller


70


is also taken-up by the reel


72


. Thus, the tread member


62


is taken-up in a state of being adhered to the liner


68


due to the tackiness of the tread member


62


. As a result, respective layers of the wound tread member


62


do not stick to one another.




As illustrated in

FIG. 3

, usually, the cross-sectional configuration of the tread member


62


is a so-called contour configuration in which a recess is formed in the central portion and both sides thereof project. When the tread member


62


is taken-up and stored, collapsing of this counter configuration must be suppressed.




Next, a storing device


10


for storing the reel


72


on which the tread member


62


is wound will be described.




As shown in

FIGS. 1 through 3

, the storing device


10


includes a frame


14


on a setting surface


12


.




A plurality of shaft supporting portions


16


are mounted to the arrow R direction side of the frame


14


along the directions of arrows F and B. Shafts


18


are supported so as to be freely rotatable by the shaft supporting portions


16


. The shafts


18


are connected to one another by couplings


20


.




A pulley


22


is mounted to the shaft


18


at the arrow F direction side.




A motor


24


is attached to the frame


14


, and a pulley


26


is attached to the shaft of the motor


24


.




A belt


28


is trained around the pulley


22


and the pulley


26


. Due to the driving of a motor


24


, the shafts


18


rotate.




Drive rollers


30


are attached to the shafts


18


.




A moving roller device


32


is provided at the arrow L direction side of each drive roller


30


.




The moving roller device


32


includes a pair of shaft supporting portions


34


at the arrow L direction side of the frame


14


. Substantially L-shaped links


36


are rotatably supported at these shaft supporting portions


34


.




The arrow L direction side end of one link


36


is connected to the arrow L direction side end of another link


36


by a shaft


38


. A driven roller


40


is supported at the shaft


38


so as to be freely rotatable.




A flange


42


is attached to each end portion of the driven roller


40


. The flanges


42


are disposed at the outer sides of the flanges


78


of the reel


72


, and function to restrict axial direction movement of the reel


72


.




An air cylinder


44


is provided at the arrow R direction side of the shaft supporting portion


34


.




A cylinder main body


46


of the air cylinder


44


is supported so as to be freely swingable at a shaft supporting portion


48


provided at the frame


14


.




The arrow R direction side end of the link


36


is connected to a piston rod


50


of the air cylinder


44


via a pin


52


.




When the piston rods


50


of the air cylinders


44


are extended, the links


36


rotate counterclockwise, and the driven rollers


40


enter into concave portions


54


provided at the setting surface


12


, as illustrated by the two-dot chain line in FIG.


1


. (This is the first state of the present invention.)




Further, when the piston rods


50


of the air cylinders


44


are pulled in, as illustrated by the solid lines in

FIG. 1

, the links


36


rotate clockwise, and the driven rollers


40


are positioned a predetermined dimension above the setting surface


12


. (This is the second state of the present invention.)




Here, when the reel


72


is placed on the drive roller


30


and the driven roller


40


in a state in which the driven roller


40


is positioned a predetermined dimension above the setting surface


12


, the bottom end of the reel


72


is positioned above the setting surface


12


such that the reel


72


is supported by the drive roller


30


and the driven roller


40


.




In the state in which the driven roller


40


has entered into the concave portion


54


, the bottom end of the reel


72


abuts the setting surface


12


, and the reel


72


can be rolled on the setting surface


12


.




Next, operation of the storing device


10


of the present first embodiment will be described.




First, the tread member


62


formed by being extrusion molded from the extruder (not shown) is conveyed by the conveying belt


64


and, together with the liner


68


, is taken-up onto the reel


72


.




When the winding of a predetermined length of the tread member


62


has been completed, the reel


72


is removed from the rotating shaft


74


, and is taken to the storing device


10


by being rolled on the setting surface


12


or the like.




In the storing device


10


, first, as shown by the two-dot chain line in

FIG. 1

, the driven roller


40


is set in a state of being entered into the concave portion


54


(the first state of the present invention), and the reel


72


is rolled from the arrow L direction side toward the arrow R direction side in

FIG. 1

so as to abut the drive roller


30


.




Next, the piston rods


50


of the air cylinders


44


are retracted so that the links


36


are rotated in the clockwise direction. In this way, the driven roller


40


rises (the second state of the present invention), and the reel


72


is raised up so as to be separated from the setting surface


12


and so as to be supported by the drive roller


30


and the driven roller


40


.




Thereafter, the motor


24


is rotated, and the reel


72


is rotated at slow speed, for example, 180° clockwise (in the direction of arrow CW). After being rotated 180° clockwise, the direction of rotation is changed and the reel


72


is rotated 180° counterclockwise. After the reel


72


is rotated 180° counterclockwise, the direction of rotation is again changed, and the same opposite operations are repeated until the tread member


62


is to be used.




While the tread member


62


is being stored, the load caused by the wound tread member


62


itself is applied uniformly along the entire wound circumference in accordance with the rotation of the reel


72


. Thus, collapsing deformation of the tread member


62


caused by the load of the wound tread member


62


itself is made uniform along the entire longitudinal direction, such that no difference in configuration arises between the respective wound layers.




Accordingly, because the gauge within one tread which is molded as a tire is uniform along the longitudinal direction, there are no effects on uniformity.




Further, the take-up reel


72


is not rotated continuously in one direction. After the reel


72


is rotated 180°, the direction of rotation is changed. By repeating these operations, tightening up of the winding or loosening of the winding of the reel member


62


can be prevented.




By making the rotational speed slow, the setting and removal of the take-up reel


72


can be carried out safely even if the rotation of the driving rollers


30


is not stopped.




Further, the reel


72


does not have to be rotated constantly, and forward rotation and reverse rotation may be repeated intermittently.




An amount of rotation of the take-up reel


72


which is sufficient for making the deformation of the protruding portions of the tread member


62


, caused by the pressing of the weight of the tread member


62


itself, uniform throughout the respective wound layers is an integer multiple of 180°. Accordingly, after the reel


72


is rotated 360° (one rotation) for example, the rotational direction may be changed, and these operations may be repeated.




Here, a more preferable condition for operating the storing device


10


is that, each time the take-up reel is rotated 180° at a slow rotational speed, the rotational direction is changed. Here, “slow rotational speed” means a speed which is less than or equal to one-half of a rotation per minute.




Using a tire for a regular passenger vehicle as an example, the range of thicknesses of the thickest portions of treads of various sizes is usually 8 to 15 mm. In conventional methods, the winding interval is set to 15 mm or more in order to obtain a gap d between the liner and the tread. However, by using the present method, winding is carried out by using a generally used method. Thus, comparing the present invention with the conventional methods, in the case of a tread member having a relatively thin thickness of around 8 mm, the present invention allows a length of the tread member


62


which is 1.8 times that in the conventional art to be wound around the take-up reel


72


. In the case of a tread member having an average thickness of about 10 mm, the present invention allows a length of the tread member


62


which is about 1.5 times or less that in the conventional art to be wound around the take-up reel


72


.




As a result, the number of reels


72


and the amount of the liner


68


held can be made about ⅔ of that in the conventional art.

12


.




A substantially U-shaped notch


80


is formed in the distal end of the piston rod


50


. The shaft


38


at which the driven roller


40


is provided can be inserted into the notch


80


. One end side of the shaft


38


is inserted into the notch


80


of the piston rod


50


of one air cylinder


44


, whereas the other end of the shaft


38


is inserted into the notch


80


of the piston rod


50


of another air cylinder


44


.

82


are disposed on rails


84


provided at the setting surface

72


applied to the driven roller

is raised up, moves apart from the setting surface

In the above-described fifth and sixth embodiments, a tire tread member is given as an example of the elongated plastically-deformable member. However, the present invention is applicable to any rubber product or intermediate member which is elongated and plastically deforms easily, such as a side rubber, an inner liner, a chafer, or the like.




As described above, in accordance with the device and method for storing an elongated plastically deformable member of the present invention, a take-up reel, on which an elongated plastically deformable member is wound, is stored while being rotated constantly or intermittently by a rotating means. Thus, the load caused by the wound elongated plastically deformable member itself can be applied uniformly to the entire wound circumference in accordance with the rotation of the take-up reel. Thus, local deformation of the elongated plastically deformable member, and non-uniform deformation in particular, can be prevented. Further, the elongated plastically deformable member is taken-up together with a liner onto the take-up reel. As the winding efficiency is improved and thus the device as a whole can be made simpler, the cost for manufacturing/maintaining the entire device can be reduced.
