(A)-(e) is a schematic diagram which respectively shows the procedure which equips a raw tire with the apparatus of FIG. (A)-(e) is a schematic diagram which respectively shows the procedure which removes a green tire from the apparatus of FIG.

  Embodiments according to the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes the whole raw tire holding device, reference numeral O denotes the extending direction of the support, and reference numeral T denotes the raw tire.

  As shown in FIG. 1, the raw tire holding device 1 includes a transport base 3 having a plurality of wheels 3 a on the lower surface, a support 5 attached perpendicularly to the transport base 3, and a side portion of the raw tire T. The raw tire T introduced from the upper end side of the support column 5 is suspended from the tire inner surface side while maintaining the horizontal posture in a posture (hereinafter also referred to as “lateral posture”) facing the transport base 3 and held. And at least one (two in this case) holding portions 7 and 8.

  The support column 5 is composed of an inner cylinder 10 and an outer cylinder 11 arranged in an inner and outer double, and is fixed to the transport base 3 by a fixing bracket (socket) 13 at the lower end of the outer cylinder 11. The inner cylinder 10 is inserted into the outer cylinder 11 and is elastically supported by springs 15 and spacers 16 as dampers disposed in the outer cylinder 11.

  Each of the holding portions 7 and 8 includes a plurality of holding members 18 and 20 including first portions 18a and 20a and second portions 18b and 20b that extend linearly and intersect each other to form an L shape. The holding members 18 and 20 are respectively arranged around the support column 5 at intervals in the circumferential direction via ring-shaped mounting brackets 23 and 24 fixed to the support column 5. In addition, each holding member 18, 20 serves as a pivot for the projections 23a, 24a projecting from the outer periphery of the mounting brackets 23, 24 at the intersection of the first portions 18a, 20a and the second portions 18b, 20b. The first portion 18a, 20a and the second portion 18b, 20b are swung at the crossing positions of the first portion 18a, 20a and the second portion 18b, 20b in a plane including the extending direction O of the support column 5, respectively. It is configured to be movable. That is, the holding members 18 and 20 are configured to swing only when a certain external force is applied by the tightening force of the screw 26, rather than being freely swingable.

  Further, in this example, the holding parts 7 and 8 are provided in a plurality of stages in the extending direction as described above, but the holding part 7 other than the lowest stage among the plurality of holding parts 7 and 8 has the first portion. 18a and the second part 18b are formed as separate bodies and are connected to each other by the screw 26, so that the crossing angle between the first part 18a and the second part 18b is in the range of 0 to 90 degrees. It is configured to be variable. Of course, the “variable” here means that the first portion 18a and the second portion 18b are fastened by the screw 26, and therefore the crossing angle between the first portion 18a and the second portion 18b only under the action of a predetermined external force. It can be changed. Further, in this embodiment, as shown in FIG. 2, in the holding portion 7 other than the lowest stage, the first portion 18a and the first portion 18a and the second portion 18b are arranged so that the intersection angle between the first portion 18a and the second portion 18b does not exceed 90 degrees. A stopper 30 is provided between the two portions 18b. In addition, the shape, arrangement | positioning, etc. of the stopper 30 are not limited to the example of illustration. Since each holding member 20 of the lowermost holding portion 8 is formed integrally with the first portion 20a and the second portion 20b, the crossing angle is constant and no stopper is required.

  In order to store or transport the raw tire T using the raw tire holding device 1 as described above, first, as shown in FIG. 3A, each holding member 18 in the holding portion 7 other than the lowermost stage. The first portion 18a and the second portion 18b that constitute the structure are closed (that is, the crossing angle is reduced), and the first portion 18a and the second portion 18b are both placed along the column 5. This prevents the raw tire T from interfering with the upper holding portion 7 when the raw tire T is introduced from the upper end side of the support column 5 in the horizontal posture as shown in FIG. it can.

  Next, when the raw tire T is introduced as shown in FIG. 3 (b), each holding member 20 of the lower holding portion 8 is formed on the outer surface of the side portion of the raw tire T that is positioned downward in the horizontal posture. The second portion 20b is pushed downward. In conjunction with the pressing operation of the second portion 20b, the first portion 20a of each holding member 20 swings and enters the inside (inner surface side) of the raw tire T as shown in FIG. The raw tire T can be suspended from the tire inner surface side and held by the member 20.

  Next, when the raw tire T is also held by the upper holding portion 7, first, as shown in FIG. 3 (c), the first portion 18 a and the second portion 18 of each holding member 18 are held in the holding portion 7. The part 18b is expanded to about 90 degrees. Thereafter, as in the case of the lower holding portion 8, the raw tire T is introduced from the upper end side of the support column 5 while maintaining the horizontal posture, and the upper holding is performed on the outer surface of the side portion located below the raw tire T. The second portion 18b of each holding member 18 of the portion 7 is pushed downward. In conjunction with the push-down operation of the second portion 20b, the first portion 18a of each holding member 18 swings as shown in FIGS. 3D and 3E, and enters the inside (inner surface side) of the raw tire T. Therefore, the raw tire T can be suspended from the tire inner surface side and held by the holding member 18.

  On the other hand, when the raw tire T is removed from the state shown in FIG. 4A, first, as shown in FIG. 4B and FIG. The raw tire T held by the portion 7 is pulled upward, and the first portion 18a of each holding member 18 is pushed upward. By pushing up the first portion 18 a, the first portion 18 a shifts to a posture along the extending direction O of the support column 5, so that the raw tire T can be removed from the device 1. Next, as shown in FIG. 4 (d), the second portion 18 b of each holding member 18 of the upper holding portion 7 is also folded along the support column 5, and then the raw tire T held by the lower holding portion 8. Is lifted upward, and the first portion 20a of each holding member 20 is pushed upward. By pushing up the first portion 20a, the first portion 20a shifts to a posture along the extending direction O of the column 5 as shown in FIG. 4E, so that the raw tire T can be removed from the device 1. .

  Therefore, according to the raw tire holding device 1, unlike a conventional bladder type device, a compressor, a pressure regulating valve, an on-off valve, piping, a power source and the like for feeding compressed gas to the bladder are unnecessary, and the equipment is large. Never become. Further, when removing the raw tire T from the apparatus 1, the holding of the raw tire T by the holding members 18 and 20 is released simply by pulling the raw tire T upward, so that the operation can be simplified.

  Further, according to the raw tire holding device 1 of this embodiment, a plurality of holding portions 7 and 8 are provided, and the crossing angle between the first portion 18a and the second portion 18b is set to 0 degree in the holding portions 7 other than the lowest level. Therefore, when the raw tire T is introduced into the lower holding portion 8 (holding portion other than the uppermost stage), and the raw tire T held by the lower holding portion 8 is When pulling up and removing from the apparatus 1, it is possible to prevent the raw tire T and the upper holding portion 7 from interfering with each other, and the good shape of the raw tire T can be maintained.

  In particular, in this embodiment, since the upper holding portion 7 is provided with the stopper 30 that prevents the intersection angle between the first portion 18a and the second portion 18b from exceeding 90 degrees, for example, FIG. ), When the raw tire T is introduced from the upper end side of the support column 5 and the second portion 18b of each holding member 18 of the upper holding portion 7 is pushed down by the raw tire T, the second It can be prevented that only the portion 18b swings downward and the swing of the second portion 18b is not transmitted to the first portion 18a, that is, the intersection of the first portion 18a and the second portion 18b. Even if the angle is configured to be variable, it is possible to reliably hold the raw tire T by the holding member 18.

  Further, in this embodiment, since the spring 15 is configured to elastically support the inner cylinder 10 and, by extension, the holding portion 7 attached to the inner cylinder 10, even if vibration occurs during transportation, the vibration is generated by the spring 15. Can be absorbed and relaxed, and the raw tire T held by the holding portion 7 can be prevented from being deformed by such vibration. In this example, the upper holding portion 7 is attached to the inner cylinder 10, but the lower holding portion 8 may be attached to the inner cylinder 10 and elastically supported. Further, rubber may be used as the damper instead of the spring 15.

  The present invention has been described above based on the illustrated examples. However, the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the claims. For example, In the above-described embodiment, it has been described that the holding portion is provided at two places on the support column, but may be provided at three or more places. Further, the number of holding members in each holding portion is not limited to six as long as it is three or more, and is preferably eight. Furthermore, the number of support columns standing on the conveyance base is not limited to one and may be two or more.

  Thus, according to the present invention, it is possible to provide a raw tire holding device that does not require large-scale equipment and can be easily attached to and detached from the raw tire device.
