Description

  The present invention relates to a method for holding and storing an unvulcanized tire (raw tire after molding treatment and before vulcanization treatment), a method for holding and storing an unvulcanized tire, and a tire (product tire used by putting air). Regarding the manufacturing method, even if it is a large unvulcanized tire, even if it is stored until vulcanization without causing deformation, distortion or damage to the unvulcanized bead part (the part that becomes the bead part in the product tire) Deformation and distortion of the unvulcanized tread part (the part that becomes the tread part of the product tire), the unvulcanized sidewall part (the part that also becomes the sidewall part) and the unvulcanized shoulder part (the part that also becomes the shoulder part) It is related with the holding | maintenance storage tool which can also reduce and can be conveyed (transfer) and stored easily.

  Conventionally, unvulcanized tires that have been assembled and molded from tire parts and inserted out of the molding machine are used from molding machines to vulcanizers (such as vulcanizing unvulcanized tires from the molding processing section in the manufacturing plant). In the vulcanization section, it is inserted into a vulcanizer and vulcanized, and is subjected to a tread pattern process and a marking process as necessary to obtain a product tire. At this time, the unvulcanized tire may be stored while being transported and held, or transferred to a storage tool, for example, for about one day to one week until vulcanization is performed.

  As a conventional technique for holding unvulcanized tires, particularly large-sized tires used in aircraft, construction vehicles, and transportation vehicles, and transporting them from a molding machine to a vulcanizer, a vertical posture (vertical installation) is not used. There has been a case in which an L-shaped or key-shaped hook is engaged with an unvulcanized bead portion of a vulcanized tire and is suspended and conveyed in a vertical posture.

  In addition to the above, regarding the prior art for transporting an unvulcanized tire from a molding machine to a vulcanizer, there are the following. A holder has been proposed in which an uncured tire in a horizontal position (horizontal position) is wound around the entire circumference with an annular body incorporating an electromagnet, and this annular body is suspended in a horizontal position by an inverted Y-type suspension cable. (For example, refer to Patent Document 1).

  In addition, an annular tube is disposed on the carriage in advance, and a large-sized tube is provided on the annular tube so that the unvulcanized shoulder portion is in contact with the unvulcanized bead portion. A support has been proposed in which an unvulcanized tire is placed in a horizontal posture, and a cart on which the large unvulcanized tire is placed horizontally is moved by an operator's human power (see, for example, Patent Document 2).

  Furthermore, the unvulcanized tires inserted from the molding machine are placed in a vertical position (vertically placed) on a hammock-type carriage by the operator's human power, and this cart is vulcanized by the operator's human power. And then gripping the unvulcanized tire in a vertical position by engaging an L-shaped hook with the unvulcanized bead portion of the unvulcanized tire on the carriage and transferring it to the vulcanizer A transfer machine has been proposed (see, for example, Patent Document 3).

  Further, a holding and conveying machine has been proposed in which an L-shaped hook is engaged with an unvulcanized bead portion of an unvulcanized tire in a horizontal posture, suspended and held in a horizontal posture (for example, see Patent Document 4). . In addition, in the production line for large tires used in aircraft, construction vehicles, and transportation vehicles, the unvulcanized tires are installed vertically, taking into account the convenience of holding and transporting large unvulcanized tires in a vertical position. A molding machine that can be inserted in a posture and a vulcanizer that can insert an unvulcanized tire in a vertical posture have been used or developed.

  However, as in the above prior art, hooking a hook on the unvulcanized bead and holding it suspended, transporting and transferring, especially in the case of large tires such as tires of aircraft, construction vehicles and transportation vehicles In some cases, the unvulcanized bead portion hook is deformed or damaged at the portion where the hook is engaged. In addition, this may cause a reduction in production yield of product tires.

  Furthermore, if it is necessary to store unvulcanized tires, hook the hooks to the unvulcanized beads and store them in a vertical position. It may be deformed into a ring shape, or distortion may occur in the unvulcanized tread portion. As a result, the production yield of product tires may be further reduced.

  Further, in the above-described conventional technology, the unvulcanized tire is turned from the vertical posture to the horizontal posture, or vice versa, or further, the unvulcanized tire is transferred to the carriage after turning or in the vertical posture. Work is required, but in the case of heavy unvulcanized tires, it is difficult to perform these operations manually by the operator.

  In addition, a large space is required for one unvulcanized tire in order to hold, convey and store the large unvulcanized tire in a horizontal posture. Conventional supports for placing unvulcanized tires in a horizontal position on an annular tube arranged in advance on the carriage, conventional holders for holding and transporting other unvulcanized tires in a horizontal position, etc. Then, since a large horizontal space is required for each unvulcanized tire, it is difficult to store many unvulcanized tires in a storage compartment in a compact manner.

  The storage time of unvulcanized tires is generally longer than the time required to hold and transport from the molding machine to the vulcanizer without storage, so a large horizontal space must be secured in the unvulcanized tires during storage. The fact that it does not become a demerit in the construction of the tire production line. Moreover, in the conventional holder using the reverse Y-type suspension cable, since it is necessary to incorporate an electromagnet in the torus, the structure of the holder becomes complicated, and along with the holding work of the unvulcanized tire Since an electromagnet connection / disconnection operation is required, the holding operation is complicated.

  As described above, it is difficult to say that the above-described conventional holders and the like are suitable for holding and conveying large unvulcanized tires, and particularly for storage. The present invention has been made in order to solve such a conventional problem, and in particular, even in a large unvulcanized tire, deformation of an unvulcanized dread portion or the like without causing deformation or damage to an unvulcanized bead portion. Alternatively, an object of the present invention is to provide an unvulcanized tire holding and storing tool that can be held and transported and stored while reducing distortion.

In order to achieve the above object, an unvulcanized tire holding and storing device of the present invention is a holding and storing device for holding an unvulcanized tire in a substantially vertical posture and storing it until vulcanization processing. A hanging band portion that is wound around and contacted with the peripheral surface excluding the top portion of the unvulcanized tread portion of the vulcanized tire, is extended from one end of the hanging band portion, and is separated from the unvulcanized tire. A first stretched portion that is stretched; a second stretched portion that is extended from the other end of the hanging band portion and is spaced apart from the unvulcanized tire; and the first stretched portion, A clip portion that is continuously provided between the second stretch portions, and in which the horizontal interval between the first stretch portion and the second stretch portion is narrower than the diameter of the unvulcanized tire; When storing the supported portion that is suspended when suspended and at least the unvulcanized tire that is suspended and retained, Between the part in the middle of the part and the part in the middle of the second stretch part, and is arranged on the peripheral surface of the unvulcanized tread part by the tension of the first stretch part and the second stretch part. And a pressing guide portion that contacts and presses the top portion.

  According to the present invention, the hanging belt portion is brought into contact with the peripheral surface of the unvulcanized tread portion excluding the top portion, the supported portion is supported, and the first and second tension portions are supported by the clip portion. The rack is tilted inward and stretched, and the top portion of the unvulcanized tread portion is pressed according to the tension of the first stretch section and the second stretch section by the pressing guide section, and the unvulcanized tire is By holding and transporting and storing in a substantially vertical posture, there is no excessive force such as hooking the unvulcanized bead part when holding and transporting and storing unvulcanized tires. The deformation and damage of the unvulcanized bead part can be prevented, and the entire surface of the unvulcanized tread part can be pressed with substantially equal force when storing the unvulcanized tire. The deformation or distortion of the vulcanized dread can be reduced. There is an effect that it is possible to improve the Ya manufacturing yield.

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described in detail below with reference to the drawings. FIG. 1 is a diagram for explaining a configuration example of an unvulcanized tire holding and storing tool according to Embodiment 1 of the present invention. FIG. 1 (a) is a front view when an unvulcanized tire is held, and FIG. It is a side view. The configuration example of FIG. 1 is a configuration example using an annular flat band (flat belt).

  The unvulcanized tire holding and storing device 100 according to the first embodiment of the present invention includes a hanging band portion 110, a first stretching portion 120, a second stretching portion 130, a clip portion 140, and a supported portion. 150 and a pressing guide portion 160. The holding storage device 100 of the first embodiment suspends and holds an unvulcanized tire (particularly a large one) 600 in a substantially vertical posture, conveys it from a molding machine (molding processing section) to a storage section, and further stores the storage section. The unvulcanized tire 600 stored in the vehicle is suspended and held in a substantially vertical posture and is transported to a vulcanization processing section where a vulcanizer is disposed.

  When the unwrapped tire 600 is held in a substantially vertical posture, the hanging band portion 110 has a circumferential surface excluding the top of the unvulcanized tread portion (the portion that becomes the tread portion of the product tire) of the unvulcanized tire 600. It is a portion that is wound around in contact with and supports the unvulcanized tire 600. The hanging band portion 110 is, for example, a band (belt) made of rubber, leather, or fiber coated with fibers or a flexible metal.

  When the holding storage device 100 suspends and holds the unvulcanized tire 600 in a substantially vertical posture, the hanging band portion 110 does not tilt the unvulcanized tire 600 between the unvulcanized tread portion peripheral surface. It is desirable to generate a moderate frictional force. In addition, when the hanging band portion 110 is long, is it flexible enough to be able to easily contact the circumferential surface of the unvulcanized tread portion without a gap, and is the stretchability low? In addition, it is desirable that the short length has a width dimension of, for example, 2/3 or more of the width dimension of the unvulcanized tread portion peripheral surface, and has low or no flexibility. For this reason, it is desirable that the hanging band unit 110 is a flat band having the above characteristics, for example.

  The first stretch section 120 extends from one end of the hanging band section 110, and when the unvulcanized tire 600 is held in a substantially vertical posture, the unvulcanized tread section circumference of the unvulcanized tire 600 is measured. It is a portion that is stretched away from the surface. The second stretched portion 130 is extended from the other end of the hanging band portion 110, forms a pair with the first stretched portion 120, and holds the unvulcanized tire 600 in a substantially vertical posture. Further, it is a portion that is stretched away from the peripheral surface of the unvulcanized tread portion of the unvulcanized tire 600. The first tension part 120 and the second tension part 130 are, for example, a rubber band, a leather band, or a fiber band or rope coated with a fiber or a flexible metal.

  However, the first stretched portion 120 and the second stretched portion 130 are less likely to be twisted around the vertical axis when the unvulcanized tire 600 is held and stretched, that is, twisted. It is desirable that they are not easily entangled with each other. This is because when the holding storage device 100 holds the unvulcanized tire 600 suspended in a substantially vertical position, the unvulcanized tire 600 rotates horizontally around the vertical axis in consideration of the ease of transportation and safety. This is because it is desirable that it is difficult.

  Therefore, the first stretch part 120 and the second stretch part 130 have low flexibility and low extensibility within a range in which it is possible to ensure that the first stretch part 120 and the second stretch part 130 can be inclined and stretched straight. It is desirable that the length is short and the flexibility is low or not. For this reason, it is desirable that the first stretch part 120 and the second stretch part 130 are flat bands having the above-described characteristics, for example.

  In the configuration example of FIG. 1, the hanging band portion 110 and the first stretching portion 120 and the second stretching portion 130 connected to both ends thereof are integrally configured by one annular body. And, when the unvulcanized tire 600 is suspended and held in a substantially vertical posture by the holding storage device 100, the portion of the torus that comes into contact with the circumferential surface of the unvulcanized tread portion becomes a substantially arc shape. The two portions that become the band portion 110 and are stretched apart from the peripheral surface of the unvulcanized tread portion become the first stretch portion 120 and the second stretch portion 130, respectively.

  By providing the clip portion 140, the first stretch portion 120 and the second stretch portion 130 are each stretched in an inclined manner. For this reason, the boundary part of the contact part with the unvulcanized tread part peripheral surface and the separation part in the above-mentioned torus is located between the top part and both side parts of the unvulcanized tread part peripheral surface. Become.

  And the part (separation part) from the said boundary part to the clip part 140 among the said torus is the 1st stretch part 120 and the 2nd stretch part 130, respectively, and the 1st stretch part 120 and the 2nd stretch part are respectively. A portion (abutting portion) between the bridge portions 130 becomes the hanging band portion 110. Therefore, in the above-mentioned torus, the boundary between the hanging band portion 110, the first stretched portion 120, and the second stretched portion 130 is the diameter dimension r of the unvulcanized tire 600 to be held and the height position of the clip portion 140. Will vary.

  For this reason, in the case where the hanging band unit 110, the first suspension unit 120, and the second suspension unit 130 are configured integrally, a portion that can be the hanging band unit 110 is desired for the hanging band unit 110. For example, it is desirable to form a flat band having the above-mentioned characteristics, and to configure the remaining portion, for example, a flat band having the above-mentioned characteristics desired for the first stretch part 120 and the second stretch part 130. In the configuration example of FIG. 1, the first stretching portion 120 and the second stretching portion 130 are configured by a flat band having the same characteristics as the hanging band portion 110. The reason why the characteristics desired for the hanging band part 110 is satisfied is that the characteristics desired for the first tension part 120 and the second tension part 130 are also satisfied.

  The clip portion 140 is connected between the first stretch portion 120 and the second stretch portion 130, and the horizontal interval between the first stretch portion 120 and the second stretch portion 130 at the continuous position is set. By making it smaller than the diameter dimension r of the unvulcanized tire 600, the first stretched portion 120 and the second stretched portion 130 are tilted inward and stretched. The height position of the clip portion 140 can be adjusted in advance when the holding storage tool 100 does not hold the unvulcanized tire 600, and the holding storage tool 100 holds the unvulcanized tire 600. In some cases, the structure is fixed to the set height position. In the configuration example of FIG. 1, the clip portion 140 is, for example, a metal ring body that wraps around the semi-peripheral surfaces of the first stretch portion 120 and the second stretch portion 130. In the configuration example of FIG. 1, the height position of the clip portion 140 is set by sliding down the clip portion 140 of the ring body after the hanging band portion 110 is hung on the unvulcanized tire 600. Is possible.

  The supported portion 150 is a portion that is hung on a hanging support such as a manually (manpowered) or electrically driven chain block or a crane hook and is suspended when the holding storage device 100 is suspended. This supported portion 150 is, for example, a rubber, leather, or fiber band or rope coated with fiber or flexible metal, like the first stretch portion 120 and the second stretch portion 130, or It is a metal chain. However, like the first stretch portion 120 and the second stretch portion 130, the supported support portion 150 is less likely to be twisted around the vertical axis when the unvulcanized tire 600 is held and stretched. It is desirable that it is a thing, that is, a thing which is not twisted and hardly entangled with each other.

  In the configuration example of FIG. 1, the supported support portion 150 is configured integrally with the first stretching portion 120 and the second stretching portion 130 by one annular body. And the part of the top side rather than the clip part 140 becomes the to-be-supported support part 150 among the said torus. In the configuration example of the torus shown in FIG. 1, since there is only one supported portion 150, it is supported by one hanging tool.

  The pressing guide portion 160 is made of, for example, wood or metal that can be regarded as a rigid body, and at least when the unvulcanized tire 600 suspended and held by the holding storage device 100 is stored, a portion in the middle of the first stretched portion 120. And the second stretched portion 130 are placed in a substantially horizontal position and unvulcanized by the tension of the first stretched portion 120 and the second stretched portion 130 that are inclined inwardly. It abuts against the top of the tread surface and presses it.

  At both ends of the pressing guide portion 160, there are a first notch portion 161 fitted to the inner surface of the first stretch portion 120 and a second notch portion 162 fitted to the inner surface of the second stretch portion 130, respectively. Is provided. The distance p between the first notch portion 161 and the second notch portion 162 is the same as the inner surface of the first stretched portion 120 when the pressure guide portion 160 is not provided on the horizontal plane in contact with the top of the unvulcanized tread portion. It is wider than the interval between the inner surfaces of the one stretch section 130 and narrower than the diameter dimension r of the unvulcanized tire 600.

  Therefore, the tension of the first stretch part 120 and the second stretch part 130 acts on the pressure guide part 160 as a resultant force that lowers the pressure guide part 160 to the unvulcanized tire side (bottom side). Also, when the first notch 161 and the second notch 162 receive the resultant force, the first notch 161 and the second notch 162 slide so that the inner surface of the first stretcher 120 and the inner surface of the second stretcher 130 come closer to the unvulcanized tire. It is possible. For this reason, when the pressing guide portion 160 is inserted between the first stretching portion 120 and the second stretching portion 130, the pressing guide portion 160 is naturally pushed down so as to contact the top of the circumferential surface of the unvulcanized tread portion. It touches and this top part is pressed.

  The manufacturing procedure of the product tire using the unvulcanized tire holding and storing tool 100 of the first embodiment will be described below. FIG. 2 is a top view illustrating a configuration example of a tire production line in which the unvulcanized tire holding and storing tool according to the embodiment of the present invention is used.

  As shown in FIG. 2, in general, in a tire production line, a molding processing section 701 including a molding machine 700 and a vulcanization processing section 801 including a vulcanizer 800 are arranged apart from each other and further store an unvulcanized tire. The storage section 901 is also arranged away from the molding processing section 701 and the vulcanization processing section 801. And the conveyance rail 1000 is constructed by the indoor top surface of this manufacturing line. The transport rail 1000 includes a molding machine-side outbound rail 1001, a storage rail 1002, a vulcanizer-side outbound rail 1003, and a return rail 1004.

  The transport rail 1000 is provided with a plurality of transfer devices 1010 such as manually or electrically driven chain blocks or cranes. These transfer devices 1010 can be moved horizontally along the transport rail 1000 by manual operation by an operator or by electric drive, and from the molding processing section 701 to the storage section 901 and from the storage section 901 to the vulcanization processing section 801. And between the vulcanization section 801 and the molding section 701 can be reciprocated.

  A plurality of holding and storing tools 100 are prepared, and the supported parts 150 are respectively supported on hooks provided at the lower ends of the suspensions (for example, suspension chains or suspension ropes) of the transfer device 1010. The unvulcanized tire 600 is suspended and held in a substantially vertical posture.

  First, in the molding processing section 701, the carcass part part, the bead part part, and the tread part part individually created by the material processing procedure are assembled and processed by the molding machine 700, thereby one unvulcanized product. The tire 600 is completed. This unvulcanized tire 600 is pivotally supported in a vertical posture and is inserted from the molding machine 700.

  Next, the unvulcanized tire 600 inserted from the molding machine 600 is suspended and held in a substantially vertical posture by the holding storage tool 100 suspended on the transfer device 1010. That is, the operator hangs the wrapping band portion 110 from the bottom of the unvulcanized tread portion circumferential surface of the unvulcanized tire 600 that is pivotally supported in the vertical posture and inserted from the molding machine 700 to at least both sides. To do. Furthermore, the first notch portion 161 and the second notch portion 162 of the pressing guide portion 160 are fitted to the inner surface of the first stretching portion 120 and the inner surface of the second stretching portion 130, respectively, so that the pressing guide portion 160 is the first. Installed between the stretch section 120 and the second stretch section 130.

  Then, after hanging the supported portion 150 on the hook of the transfer device 1010, the shaft support by the molding machine 700 is released (for example, the support shaft of the molding machine 700 is retracted), and the unvulcanized tire 600 is held and stored. Suspended by 100. It is also possible to hang the hanging band portion 110 after the supported portion 150 is previously hooked on the hook of the transfer device 1010. Furthermore, if necessary, the operator operates the transfer device 1010 to raise the holding storage tool 100 that holds the unvulcanized tire 600 in a suspended manner, whereby the holding storage tool 100 and the suspended storage tool 100 are suspended and held by the holding storage tool 100. The height position of the unvulcanized tire 600 is set to a height suitable for transportation.

  As described above, in the first embodiment, the hanging band portion 110 is hung on the circumferential surface of the unvulcanized tread portion of the unvulcanized tire 600 inserted from the molding machine 700, and suspended and held in a vertical posture. Since the unvulcanized bead portion is not contacted during the starting procedure, the unvulcanized bead portion is not deformed or damaged. In addition, during this holding start procedure, the operator only needs to hang the hanging band portion 110 around the unvulcanized tread portion peripheral surface and to install the pressing guide portion 160. Even if 600 is a large size, it can be suspended and held by the holding storage tool 100 only by performing an easy and safe operation.

  In the holding storage device 100 in which the unvulcanized tire 600 is suspended and held, the first stretching portion 120 and the second stretching portion 130 are stretched inwardly by the action of the clip portion 140, and thus the hanging portion is suspended. The boundary part of the band part 110, the first stretch part 120, and the second stretch part 130 is located between the top of the unvulcanized tread part peripheral surface and between the top part and the unvulcanized tread part. Since the hanging band part 110 abuts over a half circumference of the peripheral surface, the unvulcanized tire 600 is suspended more stably than when the first tension part 120 and the second tension part 130 are each vertically stretched. It can be held and conveyed. Further, in the holding storage device 100 in which the unvulcanized tire 600 is suspended and held, the top portion of the circumferential surface of the unvulcanized tread portion is pressed and held by the action of the pressing guide portion 160. It can be stably held and transported.

  Next, the unvulcanized tire 600 suspended and held by the holding storage tool 100 is kept in the storage section from the molding processing section 701 along the molding machine side outward rail 1001 and the storage rail 1002 of the transport rail 1000 in a substantially vertical posture. The unvulcanized tire 600 is stored in the storage section 901 while being transported (transferred) to 901 and suspended and held in a substantially vertical posture by the holding storage tool 100 hung on the storage rail 1002. In other words, the worker uses the holding storage tool 100 that holds the unvulcanized tire 600 suspended and the transfer device 1010 that supports the unstored tire 600 manually or by electric drive of the transfer device 1010, on the molding machine side forward rail 1001. And it moves along the storage rail 1002, reaches the storage section 901, and keeps it in this storage section 901 for storage. It is also possible to adopt a procedure for installing the pressure guide portion 160 when starting storage in the storage section 901 without installing the pressure guide portion 160 during the holding start procedure.

  As described above, in the first embodiment, the unvulcanized tire 600 is suspended and held in a substantially vertical posture and transferred and stored. Therefore, even if the unvulcanized tire 600 is a large size, it is suspended and held in a horizontal posture. A large horizontal space is not required unlike the case of conveyance and storage, and the conveyance space and storage space per unvulcanized tire 600 can be made compact. In particular, since storage is often longer than transportation, it is significant that the storage space can be made compact.

  Further, by installing the pressing guide 160, the portion including the bottom and both sides of the unvulcanized tread portion circumferential surface around which the hanging belt portion 110 is wound, and the vulcanized tread portion circumferential surface with which the pressing guide 160 abuts. It is possible to automatically adjust the pressing force with the top of the head. That is, when the unvulcanized tire 600 is to be deformed into an elliptical shape having a major axis in the vertical direction due to an imbalance of the pressing force from the hanging belt portion 110, the distance between the first tension portion 120 and the first tension portion 130 is determined. Therefore, the tension from the first stretch portion 120 and the first stretch portion 130 that tries to push down the pressure guide 160 to the bottom side is increased, and thus the pressure guide 160 is a top portion of the unvulcanized tread portion. Since the force which presses becomes large, the said deformation | transformation can be reduced.

  On the other hand, if the unvulcanized tire 600 tries to be deformed into an elliptical shape having a horizontal major axis due to imbalance of the pressing force from the hanging belt portion 110, the first tension portion 120 and the first tension portion 130 Since the interval becomes wide, the tension from the first stretch portion 120 and the first stretch portion 130 that tries to push the pressure guide 160 down to the bottom side is weakened, so that the pressure guide 160 becomes the top of the unvulcanized tread portion. Since the force which presses a part also becomes weak, the said deformation | transformation can be reduced.

  As described above, since the pressing force is naturally balanced on the peripheral surface of the unvulcanized tread portion, the unvulcanized tread portion, and further, It is possible to reduce deformation and distortion generated in the unvulcanized shoulder portion and the unvulcanized sidewall portion.

  Next, the unvulcanized tire 600 suspended and stored in the holding storage device 100 is stored in the storage section along the storage rail 1002 of the transport rail 1000 and the vulcanizer-side outward rail 1003 in a substantially vertical posture. It is conveyed (transferred) from 901 to the vulcanization section 801. In other words, the operator uses the storage rail 1002 and the vulcanization of the holding storage tool 100 that holds the unvulcanized tire 600 suspended and the transfer device 1010 that supports the unstored tire 600 manually or by electric drive of the transfer device 1010. It is moved along the machine-side outbound rail 1003 to reach the vulcanization section 801. In addition, it is also possible to remove the press guide part 160 at the time of the start of the said storage carrying out procedure.

  Next, in the vulcanization processing section 801, the unvulcanized tire 600 suspended from the holding storage tool 100 is inserted into the vulcanizer 800, and the holding storage tool 100 is removed from the unvulcanized tire 600. That is, the operator operates the transfer device 1010 as necessary to lower the unvulcanized tire 600 and the holding storage tool 100 that holds the unvulcanized tire 600 in a substantially vertical posture. Then, the unvulcanized tire 600 is inserted into the vulcanizer 800 (for example, the circular void of the unvulcanized tire 600 is inserted into the support shaft of the vulcanizer 800 and supported), and preparation for vulcanization processing is performed. To do. Then, the pressing guide portion 160 is removed from between the first stretch portion 120 and the second stretch portion 130, and the hanging band portion 110 is peeled off from the peripheral surface of the unvulcanized tread portion, so that the holding storage device 100 is not unloaded. Remove from the vulcanized tire 600 and complete the transfer operation.

  Thereafter, the operator moves the transfer device 1010 along the return rail 1004 of the transfer rail 1000 while holding the holding storage tool 100 removed from the unvulcanized tire 600 on the hook of the transfer device 1010, thereby forming the molding processing section. Return to 701. Alternatively, the holding storage device 100 removed from the unvulcanized tire 600 is removed from the hook of the transfer device 1010 and collected, returned to the molding processing section 701, and moved along the return rail 1004 to move the molding processing section. Return to 701. Thus, the holding and storing tool 100 that has once transported and stored the unvulcanized tire 600 can be used again, and a new unvulcanized tire 600 can be transported and stored.

  As described above, in the first embodiment, the unvulcanized tire 600 suspended and conveyed in the vertical posture by the holding storage tool 100 is inserted into the vulcanizer 800, and the hanging band portion is formed from the peripheral surface of the unvulcanized tread portion. 110 is peeled off, and the unvulcanized bead portion is not forcedly applied to the unvulcanized bead portion during the holding release procedure, so that the unvulcanized bead portion is not deformed or damaged. Further, during this holding release procedure, the operator only needs to mainly perform the work of peeling the hanging band part 110 from the peripheral surface of the unvulcanized tread part and the work of removing the pressing guide part 160. Even in the case of a large size, the holding storage device 100 can be removed only by performing an easy and safe operation.

  Next, as a final procedure, the unvulcanized tire 600 inserted into the vulcanizer 800 is vulcanized in the vulcanizer 800 and, if necessary, a tread pattern is formed on the tread portion to form a sidewall portion. The product tire is completed by, for example, performing a stamping process on.

  As described above, according to the first embodiment of the present invention, the hanging belt portion 110 is brought into contact with the peripheral surface except the top portion of the unvulcanized tread portion, and the supported portion 150 is hung and clipped. The first tension part 120 and the second tension part 130 are tilted inward by the part 140 and stretched in accordance with the tension of the first tension part 120 and the second tension part 130 by the pressing guide part 160. The top of the unvulcanized tread is pressed, and the unvulcanized tire 600 is suspended and held in a substantially vertical posture to be transported and stored, so that the unvulcanized bead is retained and transported and stored. Since it does not apply excessive force, such as hooking the hook, the deformation and damage of the unvulcanized bead portion can be prevented and the unvulcanized tread portion of the unvulcanized tire 600 can be completely stored. The peripheral surface can be pressed with almost equal force , Be stored in a substantially vertical position reduces the deformation or distortion of such unvulcanized Dread unit, thereby particularly improving the production yield of large tires.

  FIG. 3 is a diagram for explaining an example of the configuration of an unvulcanized tire holding and storage device according to Embodiment 2 of the present invention. FIG. 3 (a) is a front view when an unvulcanized tire is held, and FIG. It is a side view. The configuration example in FIG. 3 is a configuration example using a flat band (flat belt) of a string body (corresponding to an annular body having two ends and one part cut off). is there.

  The unvulcanized tire holding and storing tool 200 according to the second embodiment of the present invention includes a hanging band part 210, a first tension part 220, a second tension part 230, a clip part 240, and a supported part. 250, a pressing guide portion 260, and a connector portion 270. The holding storage tool 200 of the second embodiment suspends and holds an unvulcanized tire (particularly a large one) 600 in a substantially vertical posture, and conveys it from the molding processing section where the molding machine is arranged to the storage section, Further, the unvulcanized tire 600 stored in the storage section is suspended and held in a substantially vertical posture and is transported to the vulcanization processing section where the vulcanizer is disposed. And in the holding | maintenance storage tool 100 (refer FIG. 1) of the said Embodiment 1, the hanging band part 110, the 1st stretch part 120, the 2nd stretch part 130, and the to-be-supported support part 150 are integrally comprised by the string. In addition, the clip portion 140 and the pressing guide portion 160 are changed to the clip portion 240 and the pressing guide portion 260, respectively, and a connector portion 270 is further provided.

  When the unvulcanized tire 600 is held in a substantially vertical posture, the hanging band portion 210 has a circumferential surface excluding the top portion of the unvulcanized tread portion of the unvulcanized tire 600 (the portion that becomes the tread portion in the product tire). It is a portion that is wound around in contact with and supports the unvulcanized tire 600. The hanging band portion 210 is a band (belt) made of rubber, leather, or fiber coated with fibers or flexible metal, for example.

  When the holding storage device 200 suspends and holds the unvulcanized tire 600 in a substantially vertical posture, the hanging band portion 210 does not tilt the unvulcanized tire 600 between the unvulcanized tread portion peripheral surface. It is desirable to generate a moderate frictional force. In addition, in the length of the hanging band portion 210, is it flexible enough to be able to easily contact the circumferential surface of the unvulcanized tread portion with no gap, and is the stretchability low? In addition, it is desirable that the short length has a width dimension of, for example, 2/3 or more of the width dimension of the unvulcanized tread portion peripheral surface, and has low or no flexibility. For this reason, it is desirable that the hanging band unit 210 is a flat band having the above-described characteristics, for example.

  The first stretched portion 220 is extended from one end of the hanging band portion 210, and when the unvulcanized tire 600 is held in a substantially vertical posture, the circumference of the unvulcanized tread portion of the unvulcanized tire 600 is measured. It is a portion that is stretched away from the surface. In addition, the second stretched portion 230 is extended from the other end of the hanging band portion 210, and is paired with the first stretched portion 220 to hold the unvulcanized tire 600 in a substantially vertical posture. Further, it is a portion that is stretched away from the peripheral surface of the unvulcanized tread portion of the unvulcanized tire 600. The first tension part 220 and the second tension part 230 are, for example, a rubber band, a leather band, or a fiber band or rope coated with a fiber or a flexible metal.

  However, the first stretched portion 220 and the second stretched portion 230 are less likely to be twisted around the vertical axis when the unvulcanized tire 600 is held and stretched, that is, twisted. It is desirable that they are not easily entangled with each other. This is because when the holding storage device 200 holds the unvulcanized tire 600 suspended in a substantially vertical position, the unvulcanized tire 600 rotates horizontally around the vertical axis in consideration of the ease of transportation and safety. This is because it is desirable that it is difficult.

  Therefore, the first stretch part 220 and the second stretch part 230 are low in flexibility and low in stretchability within a range in which it is possible to ensure that the first stretch part 220 and the second stretch part 230 can be inclined and stretched straight. It is desirable that the length is short and the flexibility is low or not. For this reason, it is desirable that the first stretching part 220 and the second stretching part 230 are flat bands having the above-described characteristics, for example.

  In the configuration example of FIG. 3, the hanging band portion 210 and the first stretching portion 220 and the second stretching portion 230 connected to both ends of the hanging band portion 210 are integrally configured by a single string body. And, when the unvulcanized tire 600 is suspended and held in a substantially vertical posture by the holding storage device 200, the portion of the cord body that comes into contact with the peripheral surface of the unvulcanized tread portion and becomes a substantially arc shape is a hanging band. The two portions that are stretched apart from the peripheral surface of the unvulcanized tread portion become the first stretched portion 220 and the second stretched portion 230, respectively.

  By providing the clip portion 240, the first stretch portion 220 and the second stretch portion 230 are each stretched with an inclination inside. For this reason, the boundary site | part of the contact part with a non-vulcanized tread part peripheral surface and a separation | spacing part in the said string body will be located between the top part and both sides of a non-vulcanized tread part peripheral surface. .

  And the part (separation part) from the said boundary part to the clip part 140 among the said string bodies becomes the 1st stretch part 220 and the 2nd stretch part 230, respectively, and the 1st stretch part 220 and the 2nd stretch part A portion (contact portion) between the portions 230 becomes the hanging band portion 210. Therefore, in the cord body, the boundary between the hanging band part 210, the first stretched part 220, and the second stretched part 230 depends on the diameter r of the unvulcanized tire 600 to be held and the height position of the clip part 240. Will fluctuate.

  For this reason, when the hanging band part 210 and the first extending part 220 and the second extending part 230 are integrally configured, a portion that can be the hanging band part 210 is desired for the hanging band part 210. For example, it is desirable to configure a flat band having the above-described characteristics, and to configure the remaining portion, for example, a flat band having the above-described characteristics desired for the first and second extending portions 220 and 230. In the configuration example of FIG. 3, a portion with a short short width of the first stretch portion 220 and the second stretch portion 230 can be a hanging band portion 210 due to a change in a boundary portion between the contact portion and the separation portion. A portion having a short short width is a portion that cannot be the hanging band portion 210 (a portion that is necessarily the first stretch portion 220 and the second stretch portion 230).

  The clip part 240 is connected between the first extension part 220 and the second extension part 230, and the horizontal interval between the first extension part 220 and the second extension part 230 at the connection position is set. By making it smaller than the diameter dimension r of the unvulcanized tire 600, the first stretched portion 220 and the second stretched portion 230 are tilted inward and stretched. The height position of the clip portion 240 can be adjusted in advance when the holding storage tool 200 does not hold the unvulcanized tire 600, and the holding storage tool 200 holds the unvulcanized tire 600. In some cases, the structure is fixed to the set height position. In the configuration example of FIG. 3, the clip portion 240 is, for example, a metal flat rigid body in which both long ends are connected to the first stretch portion 220 and the second stretch portion 230, respectively. In the configuration example of FIG. 3, the linkage lock at both ends of the flat rigid clip portion 240 is released, and the clip portion 240 is detached from the first stretch portion 220 and / or the second stretch portion 230, After the hanging band part 210 is hung on the vulcanized tire 600, the clip is fixed by connecting the clip part 240 to the first stretch part 220 and / or the second stretch part 230 by locking the linkage. The height position of the part 140 can be set.

  The supported portion 250 is a portion that is hung on a hanging tool such as a manual or electric chain block or a hook of a crane and is hung when the holding storage device 200 is suspended. This supported portion 250 is, for example, a rubber, leather, or fiber band or rope coated with fiber or flexible metal, like the first stretch portion 220 and the second stretch portion 230, or It is a metal chain. However, like the first stretched portion 220 and the second stretched portion 230, the supported support portion 250 is less likely to be twisted around the vertical axis when the unvulcanized tire 600 is held and stretched. It is desirable that it is a thing, that is, a thing which is not twisted and hardly entangled with each other.

  In the configuration example of FIG. 3, the supported support portion 250 is configured integrally with the first stretching portion 220 and the second stretching portion 230 by a single string body. And the part above the clip part 240 among the said string bodies becomes the to-be-supported support part 250. FIG. In addition, in the structural example by the string body of FIG. 3, a total of two supported portions 250 will be provided separately at both ends of the string body, and in addition to hanging them with one hanging tool, It is also possible to individually hang up with two hanging tools.

  The pressing guide portion 260 is made of, for example, wooden or metal that can be regarded as a rigid body, and at least when the unvulcanized tire 600 suspended and held by the holding storage tool 200 is stored, a portion in the middle of the first stretched portion 220. And the second stretched portion 230 are installed in a substantially horizontal position and are unvulcanized by the tension of the first stretched portion 220 and the second stretched portion 230 that are inclined inwardly. It abuts against the top of the tread surface and presses it.

  In the vicinity of both end portions of the pressing guide portion 260, a first insertion portion 261 through which the first extension portion 220 is loosely inserted and a second insertion portion 262 through which the second extension portion 230 is loosely inserted are provided. It has been. And the space | interval p of the inner side of the 1st insertion part 261 and the 2nd insertion part 262 is the 1st stretch part 220 in the case of not providing the press guide part 260 in the horizontal surface which contact | connects the top part of an unvulcanized tread part. Is wider than the inner surface of the first stretched portion 230 and smaller than the diameter r of the unvulcanized tire 600.

  Accordingly, the tension of the first tension member 220 and the second tension member 230 acts on the pressure guide portion 260 as a resultant force that lowers the pressure guide portion 260 toward the unvulcanized tire side (bottom side). In addition, the inner side of the insertion portion 261 and the inner side of the insertion portion 262 slide so that the inner surface of the first stretched portion 220 and the inner surface of the second stretched portion 230 approach the unvulcanized tire when receiving the above-described resultant force. It is possible. For this reason, when the pressing guide portion 260 is inserted between the first stretch portion 220 and the second stretch portion 230, the inner surface of the first stretch portion 220 and the inner surface of the second stretch portion 230 are respectively inserted into the insertion portions. The inner side of 261 and the inner side of the insertion part 262 come into contact with each other, and the pressing guide part 260 is naturally pushed down to come into contact with the top part of the peripheral surface of the unvulcanized tread part and press the top part.

  The connector portion 270 is configured to be disposed in the middle of the first stretch portion 220 and / or the second stretch portion 230 or at the end portion on the clip 240 side (top side), and the portion is separated and connected. It is possible. The connector portion 270 can be hung by separating and connecting one portion of the long portion constituting the first stretch portion 220 and / or the second stretch portion 230 of the cord body. It serves to improve workability when the unfolded band portion 210 is hung on the unvulcanized dread portion peripheral surface of the unvulcanized tire 600 and when the unfolded band portion 210 is detached from the unvulcanized dread portion peripheral surface. .

  In the configuration example of FIG. 3, only one connector part 270 is provided on the first extension part 220, and is not provided on the second extension part 230. In the configuration example of FIG. 3, one connector portion 270 may be provided only for the second extension portion 230, and further, one connector portion 270 may be provided for each of the first extension portion 220 and the second extension portion 230. Is possible. Since the portion directly below the clip portion 240 is the top end portion of the first stretch portion 220 and the second stretch portion 230, the connector portion 270 is connected to the first stretch portion 220 and / or the second stretch portion 230. It will be arranged in the middle of the top end, or the first stretch 220 or / and the second stretch 230.

  In the tire manufacturing line of FIG. 2, a manufacturing procedure of a product tire using the unvulcanized tire holding and storing tool 200 of the second embodiment will be described below.

  A plurality of holding and storing tools 200 are prepared, and the supported parts 250 are hooked on hooks provided at the lower ends of the suspensions of the transfer device 1010 so that the unvulcanized tire 600 is substantially vertical. Suspend and hold in posture.

  First, in the molding processing section 701, the carcass part part, the bead part part, and the tread part part individually created by the material processing procedure are assembled and processed by the molding machine 700, thereby one unvulcanized product. The tire 600 is completed. This unvulcanized tire 600 is pivotally supported in a vertical posture and is inserted from the molding machine 700.

  Next, the unvulcanized tire 600 inserted from the molding machine 600 is suspended and held in a substantially vertical posture by the holding storage tool 200 suspended on the transfer device 1010. That is, the operator hangs the hanging band portion 210 from the bottom of the unvulcanized tread portion circumferential surface of the unvulcanized tire 600 inserted from the molding machine 700 while being pivotally supported in the vertical posture to at least both sides. To do. Prior to the work of hanging the hanging band part 210, the operator loosely fits the first stretching part 220 and the second stretching part 230 in the first insertion part 261 and the second insertion part 262 in advance. The inserted pressure guide 260 is positioned on the top side of the unvulcanized tire 600. In addition, before the work of hanging the hanging band part 210, the operator operates the connector part 270 in advance and separates the first extending part 220 and / or the second extending part in advance. 230, the contact / separation end portion on the side of the hanging band portion 210 is gripped and hooked on the peripheral surface of the unvulcanized tread portion, and then the contact / separation end portion is positioned on the top side of the unvulcanized tire 600. Before the uncured tire 600 is suspended and held by the holding storage tool 200 through the first insertion portion 261 and / or the second insertion portion 262 of the pressing guide portion 260, the contact / separation end portion is connected to the connector portion 270. Let

  Then, after the supported portion 250 is supported on the hook of the transfer device 1010, the shaft support by the molding machine 700 is released (for example, the support shaft of the molding machine 700 is retracted), and the unvulcanized tire 600 is held and stored. Suspended by 200. It is also possible to hang the hanging band portion 210 after hanging the supported portion 250 on the hook of the transfer device 1010 in advance. Furthermore, if necessary, the operator operates the transfer device 1010 to raise the holding storage tool 200 that holds the unvulcanized tire 600 in a suspended manner, whereby the holding storage tool 200 and the suspended storage tool 200 are suspended and held by the holding storage tool 200. The height position of the unvulcanized tire 600 is set to a height suitable for transportation.

  As described above, in the second embodiment, the hanging band portion 210 is hung on the circumferential surface of the unvulcanized tread portion of the unvulcanized tire 600 inserted from the molding machine 700, and is suspended and held in a vertical posture. Since the unvulcanized bead portion is not contacted during the starting procedure, the unvulcanized bead portion is not deformed or damaged. Further, the connector portion 270 is separated before the operation of hanging the hanging band portion 210, and the separation end portion of the connector portion 270 is pressed and guided after the hanging operation and before the unvulcanized tire 600 is suspended. By inserting the connector portion 270 through the portion 260, the hanging band portion 210 can be hung on the peripheral surface of the unvulcanized tread portion in a short time. Further, during this holding start procedure, the operator mainly hangs the hanging band part 210 around the peripheral surface of the unvulcanized tread part, the work of separating and connecting the connector part 270, and the separation end part of the connector part 270. Therefore, even if the unvulcanized tire 600 is of a large size, it can be suspended and held by the holding storage tool 200 only by performing an easy and safe operation.

  In the holding storage device 200 in which the unvulcanized tire 600 is suspended and held, the first tension part 220 and the second tension part 230 are tilted inward by the action of the clip part 240, and thereby, the hanging part is suspended. The boundary part of the band part 210, the first stretched part 220, and the second stretched part 230 is located between the top part of the unvulcanized tread part peripheral surface, and the unvulcanized tread part. Since the hanging band part 210 abuts over a half circumference of the peripheral surface, the unvulcanized tire 600 is suspended more stably than when the first and second extending parts 220 and 230 are vertically extended. It can be held and conveyed. Further, in the holding storage device 200 in which the unvulcanized tire 600 is suspended and held, the top of the circumferential surface of the unvulcanized tread portion is pressed and held by the action of the pressing guide portion 260. It can be stably held and transported.

  Next, the unvulcanized tire 600 suspended and held by the holding storage tool 200 is stored in the storage section from the molding processing section 701 along the molding machine side outward rail 1001 and the storage rail 1002 of the transport rail 1000 in a substantially vertical posture. The unvulcanized tire 600 is stored in the storage section 901 while being transported (transferred) to 901 and suspended and held in a substantially vertical posture by the holding storage tool 200 hung on the storage rail 1002. In other words, the worker uses the holding storage tool 200 that holds the unvulcanized tire 600 suspended and the transfer device 1010 that supports the unstored tire 600 manually or by electric drive of the transfer device 1010, on the molding machine side forward rail 1001. And it moves along the storage rail 1002, reaches the storage section 901, and keeps it in this storage section 901 for storage.

  As described above, in the second embodiment, the unvulcanized tire 600 is suspended and held in a substantially vertical posture, and is transferred and stored. Therefore, even if the unvulcanized tire 600 is a large size, it is suspended and held in a horizontal posture. A large horizontal space is not required unlike the case of conveyance and storage, and the conveyance space and storage space per unvulcanized tire 600 can be made compact. In particular, since storage is often longer than transportation, it is significant that the storage space can be made compact.

  Further, by installing the pressing guide 260, a portion including the bottom and both sides of the unvulcanized tread portion circumferential surface around which the hanging belt portion 210 is wound, and the vulcanized tread portion circumferential surface with which the pressing guide 260 abuts. It is possible to automatically adjust the pressing force with the top of the head. That is, when the unvulcanized tire 600 is to be deformed into an elliptical shape having a major axis in the vertical direction due to imbalance of the pressing force from the hanging belt portion 210, the distance between the first stretched portion 220 and the first stretched portion 230. Therefore, the tension from the first stretched portion 220 and the first stretched portion 230 that tries to push down the pressing guide 260 to the bottom side is increased, whereby the pressing guide 260 becomes the top portion of the unvulcanized tread portion. Since the force which presses becomes large, the said deformation | transformation can be reduced.

  On the contrary, when the unvulcanized tire 600 tries to be deformed into an elliptical shape having a horizontal major axis due to imbalance of the pressing force from the hanging belt portion 210, the first stretch portion 220 and the second stretch portion 230 Since the interval becomes wide, the tension from the first stretched portion 220 and the first stretched portion 230 that attempts to push the pressure guide 260 downward is weakened, so that the pressure guide 260 becomes the top of the unvulcanized tread portion. Since the force which presses a part also becomes weak, the said deformation | transformation can be reduced.

  As described above, since the pressing force is naturally balanced on the peripheral surface of the unvulcanized tread portion, the unvulcanized tread portion, and further, It is possible to reduce deformation and distortion generated in the unvulcanized shoulder portion and the unvulcanized sidewall portion.

  Next, the unvulcanized tire 600 suspended and stored in the holding storage device 200 is stored in the storage section along the storage rail 1002 of the conveyance rail 1000 and the vulcanizer-side outward rail 1003 in a substantially vertical posture. It is conveyed (transferred) from 901 to the vulcanization section 801. In other words, the operator uses the storage rail 1002 and the vulcanization of the holding storage tool 200 that holds the unvulcanized tire 600 suspended and the transfer device 1010 that supports the unstored tire 600 by human power or the electric drive of the transfer device 1010. It is moved along the machine-side outbound rail 1003 to reach the vulcanization section 801.

  Next, in the vulcanization processing section 801, the unvulcanized tire 600 suspended from the holding storage tool 200 is inserted into the vulcanizer 800, and the holding storage tool 200 is removed from the unvulcanized tire 600. That is, the operator operates the transfer device 1010 as necessary to lower the unvulcanized tire 600 and the holding storage tool 200 that holds the unvulcanized tire 600 in a substantially vertical posture. Then, the unvulcanized tire 600 is inserted into the vulcanizer 800 (for example, the circular void of the unvulcanized tire 600 is inserted into the support shaft of the vulcanizer 800 and supported), and preparation for vulcanization processing is performed. To do. Then, the hanging band portion 210 is peeled off from the peripheral surface of the unvulcanized tread portion, the holding storage tool 200 is removed from the unvulcanized tire 600, and the conveying operation is completed. In the operation of peeling the hanging band portion 210, the operator operates the connector portion 270 to move away from the first extending portion 220 and / or the second extending portion 230 on the hanging band portion 210 side. The contact / separation end portion is gripped and pulled out from the pressing guide portion 260 and peeled from the peripheral surface of the unvulcanized tread portion, and then the contact / separation end portion is connected to the connector portion 270 as necessary.

  Thereafter, the operator moves the transfer device 1010 along the return rail 1004 of the transfer rail 1000 while holding the holding storage tool 200 removed from the unvulcanized tire 600 on the hook of the transfer device 1010, thereby forming the molding processing section. Return to 701. Alternatively, the holding storage tool 200 removed from the unvulcanized tire 600 is removed from the hook of the transfer device 1010 and collected, returned to the molding processing section 701, and moved along the return rail 1004, and the molding processing section is moved. Return to 701. Thus, the holding and storing tool 200 that has once transported and stored the unvulcanized tire 600 can be used again, and a new unvulcanized tire 600 can be transported and stored.

  As described above, in the second embodiment, the unvulcanized tire 600 that has been suspended and conveyed in the vertical posture by the holding storage tool 200 is inserted into the vulcanizer 800, and the hanging band portion from the circumferential surface of the unvulcanized tread portion. 210 is peeled off, and the unvulcanized bead portion is not subjected to excessive force during the holding release procedure, so that the unvulcanized bead portion is not deformed or damaged. Further, in the work of peeling the hanging band part 210, the connector part 270 is separated and the peeling work is performed, and then the connector part 270 is connected as necessary, so that the hanging band part 210 is unvulcanized tread. It can be peeled off from the peripheral surface in a short time. Further, during this holding release procedure, the operator mainly removes the hanging band part 210 from the peripheral surface of the unvulcanized tread part, the work of separating and connecting the connector part 270, and the connector part 270 from the pressing guide part 260. Since it is sufficient to perform the work of removing the cut-off end portion, even if the unvulcanized tire 600 is a large size, the holding and storing tool 200 can be removed only by performing an easy and safe work.

  Next, as a final procedure, the unvulcanized tire 600 inserted into the vulcanizer 800 is vulcanized in the vulcanizer 800 and, if necessary, a tread pattern is formed on the tread portion to form a sidewall portion. The product tire is completed by, for example, performing a stamping process on.

  As described above, according to the second embodiment of the present invention, the hanging belt portion 210 is brought into contact with the peripheral surface except the top portion of the unvulcanized tread portion, and the hanging support portion 250 is hung and clipped. The first tension part 220 and the second tension part 230 are tilted inward by the part 240 and stretched in accordance with the tension of the first tension part 220 and the second tension part 230 by the pressing guide part 260. The top of the unvulcanized tread is pressed, and the unvulcanized tire 600 is suspended and held in a substantially vertical posture to be transported and stored, so that the unvulcanized bead is retained and transported and stored. Since it does not apply excessive force, such as hooking the hook, the deformation and damage of the unvulcanized bead portion can be prevented and the unvulcanized tread portion of the unvulcanized tire 600 can be completely stored. The peripheral surface can be pressed with almost equal force , Be stored in a substantially vertical position reduces the deformation or distortion of such unvulcanized Dread unit, thereby particularly improving the production yield of large tires.

  As mentioned above, although the form for implementing this invention was demonstrated in detail, this invention is not limited to these, A various change is possible in the range which does not deviate from the main point.
