Description

  The present invention mainly relates to a winding roll for winding a belt-shaped member, and particularly relates to a winding roll for an adhesive member for winding a sticky member.

When molding green tires before vulcanization, generally, an inner liner rubber member is wound on a cylindrical drum, and a carcass ply with a cord covered with rubber is wound on it, followed by bead reinforcement from both sides. A method in which a member is fitted and fixed, a side tread is wound after the carcass ply is folded back, and finally a belt and a top tread are attached (for example, see Patent Document 1).
FIG. 10A shows a cord-containing rubber member 3 in which a cord 1 is covered with a rubber member 2, such as a layer member formed by wrapping a rubber member containing a nylon cord around the carcass ply, the belt end, and the belt outer layer. In such a schematic diagram, such a belt-like corded rubber member 3 is usually made of resin or wood having a square hole 5a to which the rotary shaft 4 is connected at the center as shown in FIG. 9B. After being wound spirally on the side surface of the cylindrical winding roll 5 and temporarily stored, it is unwound together with the inner liner rubber member, belt, etc. and sent to the molding process.

Reference numeral 13 denotes an insertion portion 13a having the same cross-sectional shape as the through-hole 10S, and a widening portion 13b having an expansion / contraction slope 13k and protruding from the insertion portion 13a toward the semi-cylindrical members 11A and 11B. The first widening member 14 inserted from one bottom of the BOX roll main body 11 is a second widening member inserted from the other bottom of the BOX roll main body 11, and this second widening member 14 Has the same outer shape as the widened portion 13b and has an insertion hole 14a for inserting the insertion portion 13a of the first widened member. In addition, the first and second widening members 13 and 14 can be inserted into the first and second widening members 13 and 14 so that the slide grooves 11m and 11n can be inserted more smoothly. Introducing portions 13s and 14s whose cross sections are made smaller toward the tip side are provided.
The connecting member 12 is configured such that the connecting plate 12a is attached to one semi-cylindrical member 11A by pin members 12b and 12c, and is attached to the other semi-cylindrical member 11B by pin members 12d, thereby the two semi-cylindrical members 11A. 11B at this time, if the insertion hole of the pin member 12d formed in the connection plate 12a is a long hole 12e, the insertion of first and second widening members 13, 14 to be described later When the distance between the two semi-cylindrical members 11A and 11B, that is, the distance between the slide grooves 11m and 11n is expanded, the pin member 12d can move along the elongated hole 12e. Two semi-cylindrical members 11A and 11B can be guided in the vertical direction of FIG.
Further, 13p is a lock hole provided at the tip of the semi-cylindrical member 11A, 14p is a fixing bracket provided in the semi-cylindrical member 11B, and the first widening member 13 is replaced with the second widening member 14. When the first widening member 13 is inserted into the insertion hole 14a of the semi-cylindrical member 11B, the distal end of the fixing fitting 14p is engaged with the locking hole 13p and fixed. To do.

When the corded rubber member 3 such as a carcass ply is wound using the BOX roll 10 according to the present invention, the first widening member 13 inserted from one bottom side of the BOX roll main body 11 is Insert until the portion 13b reaches the inside of the BOX roll body 11. Since the widened portion 13b has an expansion / contraction slope 13k, the first widening member 13 can be smoothly inserted into the slide grooves 11m and 11n. Next, the second widening member 14 is inserted into the slide grooves 11m and 11n from the other bottom side of the BOX roll body 11. At this time, the insertion portion 13a of the first widening member 13 protruding outside the BOX roll main body 11 is inserted into the insertion groove 14m of the first widening member 14 and inserted into the slide grooves 11m and 11n. . Since the cross-sectional shape of the second widening member 14 is the same shape as the widening portion 13b of the first widening member 13, the outer diameter of the BOX roll body 11 is increased by twice the height of the widening portion 13b. can do.
After the insertion of the second widening member 14, the first widening member 13 is fixed to the second widening member 14 by engaging the tip of the fixing bracket 14p with the lock hole 13p. The semi-cylindrical members 11A and 11B are connected. Thereby, as shown in FIG.1 (b), the outer diameter of the BOX roll 10 can be enlarged.
Further, after the winding, if the first and second widening members 13 and 14 are extracted from the slide grooves 11m and 11n, the BOX roll body 11 becomes the original cylinder as shown in FIG. Return to. That is, the outer diameter of the BOX roll 10 can be reduced. Therefore, even if the corded rubber member 3 is reduced by tightening, the corded rubber member 3 does not adhere to the surface of the BOX roll 10. Accordingly, if the corded rubber member 3 is stored in this state, the wound corded rubber member 3 can be used without waste to the core.

  As described above, according to the best mode 1, the BOX roll 10 that winds the corded rubber member 3 is divided into two cylinders each provided with a through-hole 10S for inserting a rod-like member in the center. The two semi-cylindrical members 11A and 11B are connected by the connecting member 12 so that the distance between the two semi-cylindrical members 11A and 11B, that is, the distance between the slide grooves 11m and 11n can be expanded and contracted. A first widening member 13 having a BOX roll body 11, an insertion portion 13a having the same cross-sectional shape as the through hole 10S, and a widening portion 13b for expanding and contracting a slope 13k, in the slide grooves 11m and 11n; The second widening member 14 has the same outer shape as the widened portion 13b and has an insertion hole 14a for inserting the insertion portion 13a. The material 13 is inserted into the slide grooves 11m and 11n from one bottom portion of the BOX roll main body 11, and the second widening member 14 is inserted from the other bottom portion so that the outer diameter of the BOX roll main body 11 is increased. Since the first and second widening members 13 and 14 are extracted from the slide grooves 11m and 11n after winding, the outer diameter of the BOX roll body 11 can be reduced. Further, it is possible to prevent the cord-containing rubber member 3 wound up from sticking. Accordingly, since the corded rubber member 3 can be used up to the core, productivity can be improved.

In the first embodiment, the outer diameter of the BOX roll body 11 is increased by extending the distance between the semi-cylindrical members 11A and 11B using the first and second widening members 13 and 14. Even if one member is used, the outer diameter of the BOX roll body 11 can be increased by using a member having a wide range of the insertion portion 13a.
Moreover, in the said example, although it was set as the structure which inserts the insertion part 13a of the 1st widening member 13 protruded outside the said BOX roll main body 11 in the insertion hole 14a of the 1st widening member 14, the said BOX roll From both bottom sides of the main body 11, rod-like members having a widened portion similar to the widened portion 13 b and having a length equal to or less than half the length of the BOX roll main body 11 are inserted into the slide grooves 11 m and 11 n, respectively. It may be.

Embodiment 2. FIG.
FIG. 2 is a diagram showing a schematic configuration of a BOX roll 20 according to Embodiment 2 of the present invention, in which 21 is a roll body made of resin and 22 is spirally wound around the outer periphery of the roll body 21. The silicon tube 23 is a plurality of plates attached to the outside of the silicon tube 22 at predetermined intervals, and 24 is a pressure regulator connected to a gas cylinder 25 for filling the silicon tube 22 with gas at a predetermined pressure. A valve 26 is an open valve for releasing the gas in the silicon tube 22 into the air.
When the corded rubber member 3 such as a carcass ply is wound using the BOX roll 20 according to the present invention, the pressure adjusting valve 24 is opened to bring the gas from the gas cylinder 25 into the silicon tube tube 22 to a predetermined pressure. Fill until That is, as shown in FIG. 3A, the corded rubber member 3 is wound in a state where the silicon tube 22 is filled with gas and expanded to increase the outer diameter of the BOX roll 20. And after winding, the said open valve 26 is open | released and the pressure in the said silicon tube tube 22 is returned to atmospheric pressure. As a result, as shown in FIG. 3B, the outer diameter of the BOX roll 20, that is, the surface connecting the outer circumferences of the plates 23 is reduced, so that the corded rubber member 3 is reduced by tightening. However, the corded rubber member 3 does not adhere to the surface of the BOX roll 20 (here, the surface of the plate 23). Accordingly, if the corded rubber member 3 is stored in this state, the wound corded rubber member 3 can be used without waste to the core.

Embodiment 3 FIG.
FIG. 4 is a diagram showing a schematic configuration of a BOX roll 30 according to Embodiment 3 of the present invention. In FIG. 4, 31 is a cylindrical roll core member, and 32 is a cylinder divided in parallel to the axial direction. A widening member extending in the length direction of the roll and having a substantially fan-shaped cross section, and 33 is a linear actuator that is a slide mechanism for sliding the widening member 32 radially outward. The cylinder 33a is fixed to the bottom surface of the core member 31, and the tip of the cylinder rod 33b, which is a movable portion, is fixed to the mounting portion 32b protruding from the bottom surface of each of the widening members 32. When the corded rubber member 3 is wound, as shown in FIG. 5 (a), the cylinder rod 33b is extended and the widening members 32 are slid outward in the radial direction of the BOX roll 30, and the outer diameter thereof is increased. Increase Further, after winding, the cylinder rod 33b is reduced. As a result, as shown in FIG. 5B, the outer diameter of the BOX roll 30 is reduced. If the corded rubber member 3 is stored in this state, the corded rubber member 3 is stored. Can be prevented from coming into close contact with the surface of the BOX roll 30.
As the slide mechanism, a linear guide having no drive mechanism may be used instead of the linear actuator 33. However, in this case, when a stopper member is separately provided and the diameter of the BOX roll 30 is increased, the position of the linear guide is fixed, and the stopper member is opened after winding. Since the position of the linear guide is returned to the position before extension, the outer diameter of the BOX roll 30 is reduced.

Moreover, although the said Embodiment 1-3 demonstrated the case where the rubber member 3 with cords, such as a carcass ply which is a tire part, was wound up and stored, it is not restricted to this, It is like a tread member of a tire. The present invention can also be applied to winding and storage of adhesive members such as rubber members, inner liners, or adhesive tapes.
In the above example, the first and first slide grooves 11m and 11n provided at the center of the BOX roll body 11 formed by connecting the two semi-cylindrical members 11A and 11B so that the distance between them can be expanded and contracted. Two widening members 13 and 14 are inserted and used to increase the outer diameter of the BOX roll main body 11, or a silicon tube 22 is wound around the outer periphery of the roll main body 21 to adjust the amount of gas filled in the tube 22. Then, the outer diameter of the BOX roll 20 is expanded or contracted, or a BOX roll 30 composed of a plurality of widening members 31 slidable in the radial direction is produced, and the widening member 31 is slid to change the diameter of the BOX roll 30. However, the structure of the BOX roll according to the present invention is not limited to this, and after winding the adhesive member, As long as it can be stored the tacky member in the state of being reduced, it may be other configurations.
For example, as shown in FIGS. 6 (a) and 6 (b), a roll body 41 of a BOX roll 40 is configured by two members 41a and 41b connected by hinges 42 in the radial direction. If the gap between the two members 41a and 41b is widened with the hinge 42 as a fulcrum, and the gap is reduced after winding, the adhesiveness can be reduced with the outer diameter of the BOX roll 40 reduced. These members can be stored.
Further, as shown in FIGS. 7A and 7B, widening members 52 a and 52 b having a semicircular cross section obtained by attaching R to a sheet metal and being bent on both outer sides of a cylindrical roll body 51, for example, A slidable mechanism 52 such as a linear actuator is slidably mounted in the radial direction of the roll main body 51. When winding, the widening member 52a is slid radially outward to increase the outer diameter of the BOX roll 50. After winding, the widening member 52b may be returned to its original position to reduce the outer diameter of the BOX roll 50.
Alternatively, as shown in FIG. 8, an expansion member 62 such as a cloth-filled bladder is disposed on the side surface of a cylindrical roll body 61, and the expansion member 62 is filled with gas to increase the outer diameter of the BOX roll 60. In addition, after the winding, the outer diameter of the BOX roll 60 may be reduced by removing the gas.

  Further, as shown in FIGS. 9A and 9B, the BOX roll 70 is inserted into the spring member 71 bent into a cylindrical shape and the opening of the spring member 71, and the outer diameter thereof is The bottom surface members 72a and 72b having a cross-sectional shape that expands toward the outside of the spring member 71 are connected to the bottom surface members 72a and 72b, and the distance between the bottom surface members 72a and 72b is adjusted. The adjusting bolt 73 may be configured. That is, by adjusting the insertion length of the adjusting bolt 73, the distance between the bottom surface members 72a and 72b can be expanded and contracted to change the insertion depth of the bottom surface members 72a and 72b into the spring member 71. With this configuration, at the time of winding, the outer depth of the BOX roll 70 can be increased by increasing the insertion depth and expanding the spring member 71. In addition, after winding the adhesive member, if the insertion depth is reduced, the spring member 71 returns to its original state, and the outer diameter of the BOX roll 70 is reduced. Therefore, after winding the adhesive member, the adhesive member can be stored with the outer diameter of the BOX roll 70 reduced, so that the adhesive member is placed on the surface of the BOX roll 70. It can prevent sticking.

Since the shrinkage amount of the adhesive member varies depending on the material, how much the outer diameter of the BOX rolls 10 to 70 is reduced is determined by measuring the actual shrinkage amount.
Benchmark was put before winding the corded member A, cut out after winding and the shrinkage was measured, and the shrinkage was 2-3mm / 300mm.
On the other hand, when the roll diameter is 100 mm, the circumference is L = 200 × π≈628 mm. Therefore, when the cord-containing member A is wound around the roll, it is expected that the winding is tightened by about 6 mm when considered in a lenient manner. The Therefore, a BOX roll having the same structure as the BOX roll 10 (reducing the outer diameter by less than 1 mm) that can secure the reduction amount of 6 mm is produced, and the cord-containing member A is wound around the BOX roll and left for 5 days. Then, when the close contact state was examined, it was confirmed that there was no close contact and that all of the wound products could be used.

  Thus, according to the present invention, since the adhesion of the adhesive member to the roll can be greatly reduced, the adhesive member can be used up to the core, and productivity is improved. Can do.
