Tire vulcanizer system and assembly method therefor

1. A tire vulcanizer system obtained by coupling a plurality of tire vulcanizers each including a frame and a vulcanizing mechanism supported by the frame to vulcanize a green tire,

wherein the plurality of tire vulcanizers include:

a positioning unit that is provided in a leg unit that is provided to each of the frames and is arranged to determine relative planar positions of the frames adjacent to each other,

wherein the tire vulcanizer system includes at least one of a carrying-in unit that is arranged to carry in a non-vulcanized green tire to the tire vulcanizers, and a carrying-out unit that is arranged to carry out a vulcanized tire, and

wherein the at least one of the carrying-in unit and the carrying-out unit includes a guide rail that extends in the upward-downward direction and is coupled to the respective frames so as to stretch over the frames as a fixing part that performs positioning of the frames.

2. The tire vulcanizer system according to claim 1 ,

wherein the positioning unit includes a plurality of positioning bodies that is disposed at positions different from each other in a frontward-rearward direction perpendicular to a frame array direction in which the frames are coupled together and arrayed, and

wherein the positioning body includes a pair of positioning blocks that are arranged side by side in the frame array direction in which the frames are coupled together, are respectively fixed to the frames adjacent to each other, and abut against each other.

3. The tire vulcanizer system according to claim 2 ,

wherein the positioning blocks provided in at least one positioning body of the plurality of positioning bodies include a first surface that performs positioning in the frame array direction and a second surface that performs positioning in the frontward-rearward direction.

4. The tire vulcanizer system according to claim 3 ,

wherein the second surface is an inclined surface that inclines in the frontward-rearward direction with respect to the frame array direction.

5. The tire vulcanizer system according to claim 3 ,

wherein the positioning blocks provided in at least one positioning body of the plurality of positioning bodies include only a first surface that performs positioning in the frame array direction.

6. The tire vulcanizer system according to claim 1 , further comprising:

a mount that has a convex part on a support surface that supports the frame; and

the frame that has a concave part that allows the convex part to be inserted thereinto, and

wherein the positioning unit includes the convex part and the concave part.

7. The tire vulcanizer system according to claim 1 ,

wherein the positioning unit includes:

a first convex part that protrudes upward from a support surface of a mount that supports the frame and has a first surface that performs positioning of the leg unit of the frame in the frame array direction in which the frames are coupled together and arrayed; and

a second convex part that protrudes upward from the support surface of the mount that supports the frame and has a second surface that performs positioning of the leg unit in a frontward-rearward direction perpendicular to the frame array direction.

8. The tire vulcanizer system according to claim 1 , further comprising:

the frame including the leg unit that has a frame-side key groove formed in a lower surface thereof; and

a mount having a mount-side key groove on a support surface that supports the leg unit,

wherein the positioning unit includes:

a key mechanism that has the frame-side key groove, the mount-side key groove, and a key member and performs positioning in a frontward-rearward direction perpendicular to the frame array direction in which the frames are coupled together and arrayed; and

a first convex part that protrudes upward from the support surface of the mount that supports the frame and has a first surface that performs positioning of the leg unit of the frame in the frame array direction.

9. An assembly method for a tire vulcanizer system obtained by coupling a plurality of tire vulcanizers each including a frame provided with a leg unit and a vulcanizing mechanism supported by the frame to vulcanize a green tire, the method comprising:

a temporary assembling step of adjusting the positions of the frames adjacent to each other and temporarily coupling the frames together;

a positioning body attaching step of attaching positioning bodies for positioning to the leg units of the temporarily coupled frames, respectively;

a decoupling step of releasing the coupling between the frames with the positioning bodies attached thereto; and

a main assembling step of respectively attaching the frames between which the coupling has been released to installation locations such that the relative positions of the frames are constrained by the positioning bodies, and such that a guide rail of at least one of a carrying-in unit that is arranged to carry in a non-vulcanized green tire to the tire vulcanizers, and a carrying-out unit that is arranged to carry out a vulcanized tire, that extends in the upward-downward direction is coupled to the respective frames so as to stretch over the frames as a fixing part.
