Detailed Description

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a side view schematically showing a conveyance system 1 of the present embodiment, and fig. 2 is a plan view of the conveyance system 1 of fig. 1. As shown in fig. 1 and 2, a conveyance system 1 of the present embodiment is a system for conveying a strip-like material G to a tire building drum 2. The belt-like material G is, for example, a rubber belt for molding a tread ring of an airless tire. The belt-like material G may be a rubber belt used for molding a tread rubber of a pneumatic tire.

The conveyance system 1 of the present embodiment includes: a conveyor 3 that conveys the strip-shaped material G; a plurality of supply devices 4 that supply the belt-like material G to the transport device 3; and a cutting device 5 that cuts the strip material G.

The tire building drum 2 of the present embodiment is used to build a tire by winding a belt-like material G around its outer circumference by rotating around its rotation axis 2 a. The tyre building drum 2 may for example comprise a rigid core. The tire building drum 2 is preferably supported to be movable in the axial direction a and the vertical direction b. The tire building drum 2 can wind the belt-like material G into a predetermined tire shape by repeatedly winding the belt-like material G while moving the winding position of the belt-like material G in the axial direction a.

Here, the axial direction a is a direction in which the rotation axis 2a of the tire building drum 2 extends, that is, a direction indicated by an arrow a in fig. 2. The up-down direction b is a direction perpendicular to the axial direction a and the conveying direction c, i.e., a direction indicated by an arrow b in fig. 1. The conveyance direction c is a moving direction of the belt-like material G on the conveyor 3, i.e., a direction indicated by an arrow c in fig. 1 and 2.

The conveyor 3 according to the present embodiment is used to place the belt-like material G on the conveyor 3 and convey the belt-like material G to the tire building drum 2. Preferably, the conveyor 3 includes 1 system of main conveyor portions 6 and a plurality of systems of sub conveyor portions 7. Such a conveying device 3 can compactly arrange the main conveying portion 6 and the sub conveying portion 7, and can reduce the installation space of the conveying system 1.

The main conveyor 6 of the present embodiment is located on the tire building drum 2 side. The main conveying unit 6 includes, for example, a feeding unit 6a that feeds the belt-like material G to the tire building drum 2. Such a main conveyor 6 can smoothly feed the belt-like material G to the tire building drum 2 with a simple configuration, and can suppress the manufacturing cost.

The sub-conveying section 7 of the present embodiment is located between the main conveying section 6 and the plurality of supply devices 4. The sub-conveying section 7 is preferably connected to each of the plurality of supply devices 4. The sub-conveying section 7 can smoothly receive the plurality of kinds of strip-shaped materials G from the plurality of supply devices 4 and convey the strip-shaped materials G to the main conveying section 6.

The cutting device 5 of the present embodiment cuts the strip material G conveyed on the main conveying portion 6. Such a cutting device 5 can be disposed above the main conveying portion 6, and the installation space of the conveying system 1 can be reduced. Further, since the cutting device 5 is disposed above the 1-system main conveyor 6, it is possible to cut a plurality of types of the strip-like materials G supplied from the plurality of supply devices 4 by the 1 cutting device 5. Therefore, the cutting device 5 may be provided in 1 transport system 1, and the manufacturing cost can be reduced. In addition, maintenance of the cutting device 5 is also easy.

Next, a more preferred embodiment of the conveyance system 1 according to the present embodiment will be described.

The plurality of supply devices 4 of the present embodiment include a 1 st supply device 8 and a 2 nd supply device 9. Preferably, the 1 st supply device 8 and the 2 nd supply device 9 each comprise at least 1 reel 10 for pre-winding the band-like material G. In fig. 1 and 2, a reel 10 for replacement is shown by a two-dot chain line in addition to the reel 10 attached to the supply device 4. Such a supply device 4 can easily supply a new strip-like material G by replacing the reel 10.

The strip-like material G includes, for example, a 1 st strip-like material G1 supplied from a 1 st supply device 8 and a 2 nd strip-like material G2 supplied from a 2 nd supply device 9. Preferably, each tape-like material G is wound on the reel 10 together with the interleaving paper M. The tape-like material G of the present embodiment is peeled off from the backing paper M by the feeding device 4 and then fed to the secondary conveying portion 7. Such a tape-like material G is not adhered to each other when wound around the reel 10, and can be smoothly supplied to the conveyor 3.

The sub-conveying section 7 of the plurality of systems of the present embodiment includes: a 1 st sub-conveying unit 11 connected to the 1 st supply device 8; and a 2 nd sub-conveying section 12 connected to the 2 nd supply device 9. The 1 st sub conveyor 11 includes, for example, a 1 st sub conveyor 13. The 2 nd sub-conveyor 12 includes, for example, a 2 nd sub-conveyor 14. The 1 st sub-conveyor 13 and the 2 nd sub-conveyor 14 are constituted by, for example, belt conveyors having the same width in the axial direction a as each other. The 1 st sub-conveyor 13 and the 2 nd sub-conveyor 14 may be constituted by a plurality of belt conveyors divided in the axial direction a.

The 2 nd sub conveyor 14 of the present embodiment is positioned above the 1 st sub conveyor 13. It is preferable that the length of the 2 nd sub-conveyor 14 in the conveying direction c is longer than the length of the 1 st sub-conveyor 13 in the conveying direction c. Such a sub-conveying section 7 can be arranged compactly, and the installation space of the conveying system 1 can be reduced. The sub-conveying section 7 can smoothly convey a plurality of types of strip-shaped materials G to the main conveying section 6.

Fig. 3 is a partially enlarged view of fig. 1. As shown in fig. 3, the transport device 3 preferably further includes a transport driving unit 15, and the transport driving unit 15 moves the plurality of sub transport units 7 in a direction intersecting the transport direction c. The conveyance driving unit 15 of the present embodiment moves the sub-conveying unit 7 in the vertical direction b. Preferably, the conveyance driving unit 15 moves the 1 st sub-conveyance unit 11 and the 2 nd sub-conveyance unit 12 in the vertical direction b in synchronization with each other.

The conveyance driving unit 15 connects any one of the plurality of sub-conveying units 7 to the main conveying unit 6, for example. Fig. 3 shows a state where the 1 st sub-conveying portion 11 is coupled to the main conveying portion 6. Fig. 1 shows a state in which the 2 nd sub conveying portion 12 is coupled to the main conveying portion 6. The transport driving unit 15 can change the sub-transport unit 7 connected to the main transport unit 6 with a simple configuration, and can reduce the manufacturing cost.

Fig. 4 is a plan view schematically showing the carrying device 3 and the cutting device 5. As shown in fig. 3 and 4, the main conveying unit 6 of the conveying device 3 of the present embodiment includes: a main conveyor 16 that conveys a belt-like material G; and a table 17 having a smooth upper surface. The main conveyor 16 is constituted by a belt conveyor, for example.

The main conveyor 16 includes, for example: a 1 st main conveyor 18 including a delivery portion 6 a; and a 2 nd main conveyor 19 disposed adjacent to the table 17 in the axial direction a. The main conveyor 16 of the present embodiment includes 1 st main conveyor 18 and two 2 nd main conveyors 19.

It is preferable that the width of the 1 st main conveyor 18 in the axial direction a is equal to the width of the 1 st sub conveyor 13 and the 2 nd sub conveyor 14 in the axial direction a. It is preferable that the width of the 2 nd main conveyor 19 in the axial direction a is smaller than the width of the 1 st main conveyor 18 in the axial direction a. Such a main conveyor 16 can be compactly arranged as a whole. In addition, the 2 nd main conveyor 19 is locally in contact with the strip-shaped material G on the table 17, so that the strip-shaped material G can be smoothly conveyed.

Fig. 5 is a perspective view of the conveyor 3 and the cutting device 5 of fig. 4. As shown in fig. 3 to 5, the table 17 includes, for example, a main table 20 and a sub-table 21 that is separated from the main table 20 in the conveying direction c. Preferably, the main table 20 includes a 1 st main table 20A on the upstream side in the conveyance direction c and a 2 nd main table 20B on the downstream side. In addition, the sub-table 21 is lightly colored in each drawing for easy understanding.

As shown in fig. 4 and 5, the 1 st main table 20A is distinguished from the sub table 21 at, for example, the 1 st main end portion 20A. The 2 nd main table 20B is separated from the sub table 21 at, for example, the 2 nd main end 20B. The main table 20 is disposed with the sub table 21 interposed therebetween in the conveyance direction c, and the band-shaped material G described later can be cut with high accuracy.

The main table 20 of the present embodiment is positioned between the 1 st main conveyor 18 and the sub-conveying portion 7 in the conveying direction c. The main table 20 is formed, for example, in a substantially crank shape in its upper surface shape. The main table 20 of the present embodiment is adjacent to the 2 nd main conveyor 19 in the axial direction a and the conveying direction c. That is, the two 2 nd main conveyors 19 are located at a portion where the substantially crank-shaped main table 20 is not formed.

Therefore, the main table 20 is formed in a substantially rectangular shape together with the two 2 nd main conveyors 19 in a plan view. The connection between the main table 20 and the 1 st main conveyor 18 and the sub-conveyor 7 is smooth, and the strip-shaped material G can be smoothly conveyed. In addition, since the strip-like material G on the main table 20 is carried by the 2 nd main conveyor 19, the strip-like material G does not stay on the main table 20.

As shown in fig. 3 and 5, the sub table 21 of the present embodiment is configured to be movable in the vertical direction b. The table 17 preferably includes a table driving unit 22 for moving the sub-table 21 in the vertical direction b. The table driving unit 22 of the present embodiment moves the sub table 21 between a 1 st position (shown in fig. 3) having the same height as the main table 20 and a 2 nd position (shown in fig. 5) below the main table 20.

As shown in fig. 4, the sub table 21 is separated from the main table 20 at, for example, a 1 st sub end 21a on the upstream side in the conveying direction c and a 2 nd sub end 21b on the downstream side. The 1 st minor end 21a preferably has substantially the same shape as the 1 st major end 20 a. The 2 nd minor end 21b preferably has substantially the same shape as the 2 nd major end 20 b. The gap between the main table 20 and the sub table 21 of the table 17 is small, and the band-shaped material G is not caught.

The 1 st sub-end 21a of the present embodiment includes a 1 st straight portion 21c, and the 1 st straight portion 21c extends linearly while being inclined with respect to the conveyance direction c. The 2 nd sub-end portion 21b includes a 2 nd straight portion 21d at a position opposed to the 1 st straight portion 21c in the conveying direction c, and the 2 nd straight portion 21d extends linearly while being inclined with respect to the conveying direction c.

Preferably, the angle θ 1 of the 1 st linear portion 21c with respect to the conveying direction c is different from the angle θ 2 of the 2 nd linear portion 21d with respect to the conveying direction c. Such a sub table 21 allows the cutting angle to be changed by the cutting device 5 described later in detail, and can cut the strip G at an angle suitable for the strip G.

The 1 st sub-end portion 21a of the present embodiment includes a 3 rd linear portion 21e, and the 3 rd linear portion 21e extends linearly while being inclined at an angle different from that of the 1 st linear portion 21c with respect to the conveying direction c. Preferably, the 3 rd linear portion 21e extends continuously from the 1 st linear portion 21 c. The 2 nd sub-end portion 21b includes a 4 th straight portion 21f at a position opposed to the 3 rd straight portion 21e in the conveying direction c, and the 4 th straight portion 21f extends linearly while being inclined at an angle different from that of the 2 nd straight portion 21d with respect to the conveying direction c.

Preferably, an angle θ 3 of the 3 rd linear portion 21e with respect to the conveying direction c is equal to an angle θ 2 of the 2 nd linear portion 21d with respect to the conveying direction c. Preferably, the angle θ 4 of the 4 th linear portion 21f with respect to the conveyance direction c is equal to the angle θ 1 of the 1 st linear portion 21c with respect to the conveyance direction c. Such a sub table 21 enables the cutting device 5 to cut at different cutting angles more smoothly.

The 1 st minor end portion 21a may be formed only by the 1 st linear portion 21 c. Similarly, the 2 nd minor end portion 21b may be constituted only by the 2 nd straight portion 21 d. In this case, the upper surface of the sub table 21 is preferably formed in a substantially trapezoidal shape. Such a sub-table 21 has a simple shape, and can be manufactured at a low cost.

As shown in fig. 3 to 5, the cutting device 5 of the present embodiment is located above the sub-table 21. Preferably, the cutting device 5 is movable in the vertical direction b by a vertical position changing unit (not shown). The cutting device 5 may be lowered when cutting the strip G and raised when conveying the strip G.

The cutting device 5 may be fixed at a height capable of cutting the strip material G, for example, without moving in the vertical direction b. In this case, the cutter 23 of the cutting device 5 is preferably movable to the outside in the axial direction a of the main conveying unit 6.

The cutting device 5 of the present embodiment includes a cutter 23 that advances in the cutting direction. Preferably, the cutter 23 cuts the strip-shaped material G by positioning the tip of the cutter 23 below the upper surface of the main table 20 in a state where the sub table 21 has moved to the 2 nd position (shown in fig. 5). Preferably, the cutter 23 travels along either the 1 st major end 20a or the 2 nd major end 20 b. Such a cutter 23 can cut the strip material G reliably and with high accuracy.

In the present embodiment, since both sides in the conveying direction c of the cutting position of the strip-shaped material G are supported by the 1 st main table 20A and the 2 nd main table 20B, the strip-shaped material G is less likely to move during cutting, and the cutting accuracy can be further improved.

The cutting device 5 of the present embodiment includes an angle changing unit 24, and the angle changing unit 24 changes the cutting angle of the strip G with respect to the conveyance direction c. The angle changing unit 24 can change the cutting angle to, for example, the 1 st angle at which the cutter 23 advances above the 1 st linear portion 21c and the 4 th linear portion 21f and the 2 nd angle at which the cutter 23 advances above the 2 nd linear portion 21d and the 3 rd linear portion 21 e. Preferably, the angle changing unit 24 rotates the cutting device 5 about a position where the length of the sub table 21 in the conveying direction c is the smallest. Such a cutting device 5 can cut the strip material G at an angle suitable for the strip material G.

Next, the operation of the conveying system 1 according to the present embodiment when the strip-shaped material G is conveyed and cut will be described with reference to fig. 1 to 5.

In the transport system 1 of the present embodiment, first, the strip material G is mounted on the supply device 4 in a state of being wound around the reel 10 in advance. The 1 st supply device 8, for example, mounts the spool 10 to move in the axial direction a. The 2 nd supply device 9 mounts, for example, the reel 10 to move in the carrying direction c. Such a supply device 4 facilitates replenishment of the strip G, and can shorten the operation time.

Next, for example, the strip material G is supplied from the 1 st supply device 8 or the 2 nd supply device 9 to the 1 st sub-conveying portion 11 or the 2 nd sub-conveying portion 12 of the sub-conveying portion 7. In this case, the conveyance driving unit 15 preferably connects one of the 1 st sub-conveyance unit 11 and the 2 nd sub-conveyance unit 12 to the main conveyance unit 6. The 1 st sub-transport portion 11 or the 2 nd sub-transport portion 12 connected to the main transport portion 6 can transport the strip G to the main transport portion 6. Such a sub-transport section 7 can smoothly transport an arbitrary belt-like material G from among a plurality of kinds of belt-like materials G.

Next, the main conveyor 16 of the main conveying section 6 of the present embodiment conveys the strip-shaped material G by a predetermined length in a state where the sub table 21 is moved to the 1 st position (shown in fig. 3). The main conveyor 16 preferably conveys the strip material G in synchronization with the 1 st sub conveyor 13 of the 1 st sub conveyor 11 or the 2 nd sub conveyor 14 of the 2 nd sub conveyor 12.

At this time, the strip material G fed out from the feeding portion 6a of the main conveyor portion 6 is wound around the tire building drum 2 rotating in synchronization with the main conveyor 16 to form a tire. Such a main transport unit 6 can smoothly transport the strip G without the strip G being caught on the table 17.

For example, when the main conveyor 16 conveys the strip material G by a predetermined length, the conveyance is stopped. In the present embodiment, the belt-like material G that has stopped being conveyed is cut after the cutting device 5 and the sub table 21 have moved downward. At this time, the cutter 23 of the cutting device 5 preferably runs along the 1 st main end 20a or the 2 nd main end 20 b. Since the portion of the cutting device 5 near the cutting position is supported by the 1 st main end 20a or the 2 nd main end 20b, the cutting accuracy can be improved.

While the above description has been made on the particularly preferred embodiments of the present invention, the present invention is not limited to the above embodiments, and may be implemented in various forms.
