The belt conveyors 106 and 122 begin to flow. At this time, since the sensor A and the sensor B do not detect the long member 4, the long member 4 is supplied at a high speed.

  The long member 4 overlapped with the liner 5 by the unwinding roll 6 is separated from the liner 5 by the separation roll 33, and the free roll 34 and the guide portion 35 of the long member supply device 3 and the long member support device 50 are separated. It passes over the main support part 71 and the retractable support part 80 of the long member support part 70, and the center line in the width direction is adjusted to a predetermined position by the webster 103 of the transport device 100 and sent to the upstream belt conveyor 106. It is loaded and sent downstream.

  When the end of the long member 4 passes the positions of the sensor C112 and the sensor D113 and the long member 4 is detected, the cylinder 111 is operated and the member presser 107 is swung downward. Is pressed against the upstream belt conveyor 106 by the roller 108 of the member presser 107.

  When the member presser 107 swings downward and the roll 108 presses the elongate member 4, the elongate member support device 50 enters the festoon creation state, and the elongate member support part 70 descends while supporting the elongate member 4. Begin.

  Since the supply speed of the long member 4 of the long member supply device 3 is higher than the transfer speed of the belt conveyor 106 and the belt conveyor 122 of the transfer device 100, the supply speed between the long member supply device 100 and the transfer device 100 is high. The long member 4 is loosened and the festoon 51 is gradually generated. Since the slider 64 of the rodless cylinder 63 is moved downward in accordance with the slack of the festoon 51, the slack amount of the festoon 51 is increased while the festoon 51 is supported from below by the long member support portion 70. Can do.

  Further, as the long member support portion 70 is lowered, the guide portion 35 of the long member supply device 3 is swung downward by the cylinder 39 around the pin 37, and the long member 4 at the end of the festoon accompanying the festoon creation is moved. Prevents the flow angle from changing suddenly.

  When the slack of the festoon 51 becomes large and the sensor A 92 detects the long member 4, the supply speed of the long member supply device 3 becomes the normal speed, which is the same as the transport speed of the transport device 100. The size is maintained. When the looseness of the festoon 51 is further increased and detected by both the sensor A92 and the sensor B93, the supply of the long member 4 of the long member supply device 3 is stopped and the amount of looseness of the festoon 51 is adjusted to decrease. When the slack of the festoon 51 decreases below the predetermined value and the sensor A92 and the sensor B93 are not detected, the supply speed of the long member supply device 3 is increased, and the amount of slackness of the festoon 51 is adjusted to increase.

  As shown in FIG. 11, the long member support portion 70 is moved downward while supporting the festoon 51 from below, and supports the festoon 51 until the predetermined festoon 51 is created, but the predetermined festoon 51 is created. After that, it moves away from the lower end of the festoon 51 and is moved to the lowest position as shown in the figure, and the long member support device 50 is in the festoon creation end state.

  The long member 4 transported on the upstream transport unit 102 is cut into a predetermined length by the cutter 130 and the anvil 131 to become the tire member 2, and is further placed on the belt conveyor 122 of the downstream transport unit 120. Not sent to tire molding drum.

  While the long member 4 is being unwound from the unwinding station 10, the long sheet-like raw rubber member 4 and the liner 5 are wound in a state of being overlapped in the station 22 at the standby position 11. A new unwinding roll 6 is carried in and set in an unwindable state.

  As shown in FIG. 12, the long member 4 is substantially unwound from the unwinding roll 6 set at the station 22 at the unwinding position 10, and the final end 4b of the long member 4 passes through the sensor C112. When the sensor D113 detects the long member, but the sensor C112 does not detect the long member 4, the end material 4c of the long member 4 is on the upstream belt conveyor 106. Recognized, the member presser 107 is swung upward, and the upstream belt conveyor 106 starts to rotate in the reverse direction, and the end material 4c placed on the upstream belt conveyor 106 is upstream of the upstream conveying section 102. It is conveyed in the direction of discharging from the end. Further, it is determined that all of the long member 4 has been unwound from the unwinding roll 6, and the rotation of the driving roller 29 and the liner winding roll of the long member supply device 3 is stopped.

  As shown in FIG. 13, almost simultaneously with the upstream belt conveyor 106 starting to rotate in the opposite direction, the cylinder 88 supporting the long member support portion 70 of the long member support device 50 from below is operated. The long member support portion 70 is in the inclined state, and the long member support device 50 is in the end material discharge state.

  The end material 4c conveyed in the reverse direction is guided by the guide portion 114 provided on the downstream side of the web star 103, contacts the support surface 70a of the inclined long member support portion 70, and the free roll 72 Is rotated and discharged to the receiving bowl 125.

  When it is confirmed that the end material 4c has been discharged to the receiving rod 125, the long member support portion 70 is in a horizontal state, and the rodless cylinder 62 is moved to the uppermost position by being actuated. 80 is in a protruding state, and the long member support device 50 is in a state in which the long member can be conveyed.

  Along with this, the guide portion 35 of the long member supply device 3 is swung upward, and the movable frame 20 of the long member supply device 3 is further moved to stand by at the standby position and set to the unwindable state. The station 22 is arranged at the unwinding position 10, and the tire member supply apparatus 1 is in a member supply start state as shown in FIG.

  In the tire member supply device 1 in the member supply start state, the rotation of the driving roller 29 and the liner winding roll 31 and the unwinding of the long member 4 from the unwinding roll 6 are started, and a new unwinding roll 6 is obtained. Supply of tire members begins.

  From the station 22 that has been unwound and moved to the standby position 11, the unwinding roll 6 that has been unwound is unloaded, and a new unwinding roll 6 around which the long member 4 and the liner 5 are wound is taken into the station. Set to 22 and keep unwinding possible.

  The above process is repeated and the tire member 2 is continuously supplied.

  In the tire member supply apparatus 1 according to the present embodiment, since the festoon 51 is automatically created, the manual work by the worker is reduced, the stop time of the tire member supply apparatus 1 is shortened, and the tire manufacturing apparatus can manufacture tires. Productivity can be improved.

  Further, since the festoon is gradually created while the long member 4 is supported from below by the long member support surface 70a and does not depend on the work of the worker, the deformation of the long member 4 at the time of creating the festoon is prevented and the accuracy is improved. This makes it possible to produce tire products with a high height.

  In addition, by setting the downstream side of the long member support portion 70 to be inclined downward, the end material 4c fed back to the upstream side by the upstream belt conveyor 106 is made to be long in the long member support portion 70. Since it is received by the member support surface 70a and sent to the adjacent receiving rod 125, the end material 4c can be easily discharged, the discharge time can be shortened, and tire productivity can be further improved.

  Since the tire member supply device 1 is configured as described above, it is possible to significantly reduce the work process by the worker, and the safety of the worker is improved.
