  When a container on which a stacked body configured by alternately stacking cartridges and beads is placed at the take-out position, the handling robot takes out the bead and the cartridge from the container at the take-out position, and Are supplied to the carcass band, while the cartridges are sequentially stacked and collected in a container located at the cartridge transfer position. By repeating such an operation, when the container located at the take-out position becomes empty, first, the container at the cartridge transfer position where only the cartridges are stacked is moved to the discharge position. Next, after the empty container is moved from the removal position to the cartridge transfer position, the container on which the stacked body is placed is moved from the carry-in position to the removal position.

However, in the test KyuSo location of such a conventional bead for tires, when all beads from the take-out position the container, the cartridge is taken out container is empty, body stacked with said mounting end setting position of the container mounting The container at the standby position is replaced, and then the supply of the beads to the carcass band is resumed. At this time, the discharge position, the cartridge transfer position, the take-out position, and the carry-in position are arranged in a U-shape. Therefore, when trying to prevent interference during movement between containers, as described above, the container at the cartridge transfer position is first set to the discharge position, and then the container at the take-out position is set to the cartridge transfer position. After that, it is necessary to sequentially move the container at the carry-in position to the take-out position. As a result, three steps of work are required. Work efficiency Te there is a problem that decreases.

This invention aims to provide a test KyuSo location of the bead for a tire that can be easily improved work efficiency with a simple structure.

Such a purpose is to rotate around a rotation axis extending in the vertical direction, and having a rotary table having at least three support positions spaced equiangularly in the circumferential direction on the upper surface, and the rotation table around the rotation axis. Rotating intermittently, rotating the support position in the circumferential direction at the same angle as the support positions, and sequentially moving to the standby station, supply station, and recovery station among the same number of stations as the support position Loading means for loading a pallet on which a stacking body constituted by alternately stacking drive means, holders and beads is placed on an empty support position located at the standby station from the loading position, and a supply station Remove the bead and holder from the pallet and stack on the support position, and use the bead for the tire intermediate. On the other hand, the supply means for sequentially stacking and collecting the holder on the pallet on the support position located at the collection station, and the pallet on the support position located at any station between the collection station and the standby station An unloading means for unloading from the rotating table together with the stacked holders, and when the pallet on the support position located at the supply station is empty, the rotating table is rotated around the rotation axis by the rotating driving means, The support position for supporting the pallet on which the stacked body is placed is from the standby station to the supply station, the support position for supporting the empty pallet is from the supply station to the collection station, and the empty position Move the support position to the standby station. In the tire bead supply device, the carry-in means moves along a linearly extending support plate, and is supported by a slider to which a stopper body is fixed, and can swing on the slider in a horizontal plane. And a spring that swings the hook until it abuts against the stopper body by an urging force so that the hook is orthogonal to the support plate, and the slider is moved to be orthogonal to the support plate. By pushing the locking piece of one pallet located at the carry-in position with the hook being loaded, the pallet and the stacked body are carried into the support position located at the standby station, while when the slider returns, the hook is moved into the carry-in position. While passing through the pallet while being swung by being pushed by the locking piece of the pallet located at The tire bead is made to return to a posture orthogonal to the support plate by the urging force of the spring , and the locking piece is fixed to the lower surface of the pallet and has a cylindrical shape with a central axis extending in the vertical direction . This can be achieved by a feeding device.

  In the present invention, the rotary table is provided with support positions corresponding to at least three stations including the standby, supply, and recovery stations, the beads and the holder are taken out from the stacked body on the pallet located at the supply station, and the beads are placed in the middle of the tire. While supplying the body, the holders are sequentially stacked on the pallet located at the collection station and collected. When the pallet located at the supply station is emptied by repeatedly taking out the beads and holders described above, the rotary table is rotated around the rotation axis by the rotation driving means, and the pallet located at the standby station together with the stacked body. The empty pallet is moved to the supply station, the empty pallet is moved from the supply station to the collection station, and the empty support position is moved to the standby station.

  As a result, the stacked body is supplied to the supply station together with the pallet, and the supply of the beads to the tire intermediate body can be resumed, but after the restart of such bead supply work, the stacked body is placed by external setup. The pallet on which the holder is piled up by any means between the next station and the standby station of the collection station. If the support position is located at the station, the above-described bead supply operation can be resumed with only one step of rotating the rotary table if it is unloaded from the rotary table.

  Alternatively, when the pallet on which the holders are stacked is located at the collection station, it is possible to carry out the holder and pallet from the rotary table by the unloading means. In this case, the rotary table is rotated after the unloading. Two steps are required. Thus, the conventional method requires three steps, but in the former case, the number of steps can be reduced to one step of rotating the rotary table. In the latter case, the number of steps of carrying out the pallet and rotating the rotary table is 2 It is possible to reduce the number of steps up to the step, and thus it is possible to easily improve the work efficiency while having a simple structure.

It extends perpendicular to the direction line. Each guide body 18 is composed of a support member 19 extending in the longitudinal direction fixed to the rotary table 11, and a plurality of pairs of guide rollers 20 rotatably supported at both ends in the width direction of the support member 19. The guide roller 20 can freely rotate about an axis extending in the vertical direction. These guide rollers 20 are arranged at equal distances in the longitudinal direction of the support member 19, and a gap 21 having a constant width is formed between the paired guide rollers 20 on a single straight line.

  Further, conveyance guides 24 and 25 extending in parallel with the guide body 18 are installed at each support position 15 of the rotary table 11, and these conveyance guides 24 and 25 are on both sides of the guide body 18, that is, radially inward and The guide bodies 18 are arranged at the same distance from the guide body 18 on the radially outer side. These transport guides 24 and 25 are composed of a support member 26 that is fixed to the rotary table 11 and extends in the longitudinal direction, and a plurality of support rollers 27 that can freely rotate around a horizontal axis perpendicular to the extending direction of the support member 26. These support rollers 27 are arranged at equal distances in the extending direction of the support member 26, and their upper ends protrude upward from the support member 26.

  1 to 4, reference numeral 28 denotes a plurality of pallets having a disk shape. When these pallets 28 are supplied to the support position 15 of the rotary table 11, the pallets 28 rotate via the conveyance guides 24 and 25. Supported from below by the table 11. Each pallet 28 has a slightly smaller diameter than the radius of the rotary table 11, and a strip-like ridge 29 that passes through the center of the pallet 28 and extends linearly is fixed to the lower surface of the pallet 28. When the pallet 28 is supplied to the support position 15 as described above, the support rollers 27 of the transport guides 24 and 25 support the lower surface of the pallet 28 while being in rolling contact with each other, and form a pair of the guide bodies 18. The guide roller 20 engages with the protrusion 29 of the pallet 28 while being in rolling contact with both sides, whereby the movement direction of the pallet 28 is restricted to the extending direction of the guide body 18.

In this way, the linear guide body 18 that regulates the moving direction of the pallet 28 by engaging the ridge 29 of the pallet 28 from both sides while providing the linearly extending ridge 29 on the lower surface of each pallet 28. If installed on the turntable 11, when the pallet 28 is loaded into the support position 15 and unloaded from the support position 15, a lateral displacement with respect to the moving direction of the pallet 28 is reliably prevented with a simple structure. be able to. Locking dents 30 are formed at both ends in the longitudinal direction on the lower surface of the ridge 29, and the outer end side (outer peripheral side) side surfaces of these locking dents 30 are composed of vertical surfaces 30a extending in the vertical direction. The inner end side (center side) side surface is composed of an inclined surface 30b inclined downward toward the center in the longitudinal direction. A cylindrical locking piece 31 having a central axis extending in the vertical direction is fixed at a position apart from the protrusion 29 by 90 degrees on the outer edge of the lower surface of the pallet 28, and is engaged with the protrusion 29. A pair of square columnar stoppers 32 are fixed to the lower surface of the pallet 28 between the stoppers 31.

  Further, the flat upper surface of the pallet 28 is a mounting surface on which the stacked body 35 can be mounted. Here, the stacked body 35 alternately stacks a substantially ring-shaped holder 36 made of, for example, plastic, and a ring-shaped bead 38 having a filler 37 made of bowl-shaped unvulcanized rubber attached to the outer periphery thereof. As a result, the bead 38 with the filler 37 is supported by the holder 36 from below. Then, from the stacked body 35, two beads 38 with fillers 37 arranged adjacent to each other in the vertical direction are taken out and supplied to one tire intermediate body to be described later. In the present invention, the bead 38 may be a single body to which the filler 37 is not attached, but in this case, it is necessary to attach the filler 37 to the bead 38 in the subsequent steps.

  1 and 2, the same number as the support position 15 is set at the position overlapping the rotary table 11, and in this embodiment, four stations are set, and these four stations are set on the rotary table 11. It consists of standby, supply, recovery, and empty stations A, B, C, and D arranged along the direction of rotation. Here, these standby, supply, recovery, and empty stations A, B, C, and D are separated from the rotation axis of the turntable 11 by the same distance in the radial direction as the support position 15, and the support position 15 in the circumferential direction. They are separated by the same angle (90 degrees here). Reference numeral 41 denotes a rotation driving means for applying a rotation driving force to the rotary table 11, and the rotation driving means 41 has a large number of external teeth 42 provided on the outer peripheral portion of the rotation table 11. 43 is a support frame installed on the floor surface 13 radially outside the rotary table 11, and an external gear 44 meshing with the external teeth 42 is rotatably supported on the support frame 43 via a rotary shaft 45. Yes.

  A drive motor 47 is attached to the support frame 43, and an external gear 48 fixed to the output shaft of the drive motor 47 and an external gear 49 fixed to the rotary shaft 45 are engaged with each other. As a result, when the drive motor 47 is operated, the rotational driving force of the drive motor 47 is transmitted to the rotary table 11 via the external gear 44, and the rotary table 11 is rotated between the adjacent support positions 15 around the rotational axis. Rotate in the same direction intermittently by the same angle (90 degrees) as the angle. The drive motor 47 and the external gears 48 and 49 described above constitute a drive mechanism 50 that drives and rotates the external gear 44, and the external teeth 42, the external gear 44, and the drive mechanism 50 as a whole are a rotary table. The rotation driving means 41 is configured to intermittently rotate 11 around the rotation axis. In the present invention, the rotation drive means may be constituted by a drive motor and a gear, belt, or chain that transmits the rotation drive force of the drive motor to the rotation shaft of the rotary table.

  Here, if the rotation drive means 41 is constituted by the external teeth 42, the external gear 44, and the drive mechanism 50 as described above, even if the rotary table 11, the pallet 28, the holder 36, and the bead 38 have a large mass, a small drive The rotary table 11 can be integrally rotated around the rotation axis together with the stacked body 35 placed on the support position 15 by force, and the rotation driving means 41 can be easily downsized. Then, when the rotation driving means 41 is operated and the turntable 11 rotates at an angle between two adjacent support positions 15, here 90 degrees, the support position 15 located at the standby station A becomes the supply station B. Further, the support position 15 located in the supply station B is in the collection station C, the support position 15 located in the collection station C is in the empty station D, and the support position 15 located in the empty station D is the standby station. Move to A at the same time. Here, since the rotation of the rotary table 11 is repeated intermittently, paying attention to one support position 15, the support position 15 is in standby, supply, recovery, empty station A, B, C, D Are sequentially moved back to the original standby station A, but such a cyclic movement is repeated thereafter.

  53 is a guide body which is installed on the floor 13 behind the standby station A and has the same structure as the guide body 18. This guide body 53 is a guide body installed at the support position 15 located in the standby station A. It extends along 18 extension lines. Conveying guides 54 and 55 having the same structure as the conveying guides 24 and 25 are installed on the floor surface 13 on both sides of the guide body 53, and these conveying guides 54 and 55 are supported at the standby station A. 15 extends along an extension line of the conveyance guides 24 and 25 installed at 15. A plurality of pallets 28 loaded with stacked bodies 35 are placed on the conveyance guides 54 and 55. At this time, each pallet 28 is viewed from below by a support roller constituting the conveyance guides 54 and 55. On the other hand, the ridges 29 of each pallet 28 are engaged (rolling contact) from both sides by the guide rollers constituting the guide body 53, thereby restricting the moving direction of the pallet 28. The guide body 53 and the conveyance guides 54 and 55 described above constitute supply means 56 for supplying the pallet 28 on which the stacked body 35 is placed toward the rotary table 11 as a whole.

  57 is a loading means installed on the floor surface 13 on the left side of the rotary table 11. The loading means 57 has a support plate 58 fixed to the floor surface 13 and extending parallel to the conveyance guide 55. A guide rail 59 extending along the support plate 58 is laid on the right side surface of the support plate 58 facing the rotary table 11. Reference numeral 60 denotes a slider to which a slide bearing 61 is slidably engaged with the guide rail 59, and the slider 60 can move in the front-rear direction while being guided by the guide rail 59. The slider 60 supports a hook 63 that can swing in a horizontal plane around a pin 62. The hook 63 is stretched between the slider 60 and a stopper body 64 fixed to the slider 60. 2, when it swings clockwise in FIG. 2 until it abuts against the stopper body 64 by the biasing force of the spring 65, it extends perpendicular to the support plate 58 and engages with the locking piece 31 of the pallet 28. can do.

  68 is a drive motor fixed to the front end of the support plate 58. Between the sprocket 69 fixed to the output shaft of the drive motor 68 and the sprocket 70 rotatably supported on the rear end of the support plate 58 A chain 71, which is connected to the stopper body 64 at one halfway, is stretched over. As a result, when the drive motor 68 is activated and the chain 71 travels when the slider 60 is positioned at the rear end, the slider 60 moves forward toward the standby station A. The hook 63 extending so as to be orthogonal to the plate 58 is engaged with the locking piece 31 of one pallet 28 located at the carry-in position E set at the front ends of the conveyance guides 54, 55. The pallet 28 on which the stacked body 35 is placed moves forward while being pushed by the hook 63 and is carried into an empty support position 15 located at the standby station A.

  Thereafter, the slider 60 returns to the rear end by the operation of the drive motor 68. At this time, when a new pallet 28 is supplied to the loading position E, the hook 63 is attached to the locking piece 31 of the pallet 28. It is pushed and swings counterclockwise in FIG. 2 around the pin 62, and can return to the rear end without affecting the placement position of the pallet 28. The hook 63 returns to the posture orthogonal to the support plate 58 by the biasing force of the spring 65 when it passes through the locking piece 31 of the pallet 28. The above-described slider 60, slide bearing 61, pin 62, hook 63, stopper body 64, spring 65, drive motor 68, sprocket 69, 70, and chain 71 as a whole transfer mechanism for transferring the pallet 28 along the support plate 58. 73, and the support plate 58 and the transfer mechanism 73 as a whole are positioned at the standby station A with the pallet 28 on which the stacked body 35 configured by alternately stacking the holders 36 and the beads 38 is placed. The carry-in means 57 for carrying in the empty support position 15 is configured.

  1 to 6, particularly FIG. 5, the base end of a substantially horizontal swing arm 77 is rotatably connected to the lower surface of the rotary table 11 at a position overlapping each support position 15 via a pin 76. A tension spring 79 is interposed between the distal end of the moving arm 77 and a spring receiver 78 fixed to the rotary table 11. Here, the swing arm 77 extends along the guide body 18 immediately below the gap 21. As a result, when the pallet 28 is supported at the support position 15, the swing arm 77 is It is located along the ridge 29 just below the 28 ridges 29. Reference numeral 80 denotes a locking projection attached to the upper surface of the central portion in the longitudinal direction of each swing arm 77, and these locking projections 80 vertically penetrate through holes 81 formed in the rotary table 11 at each support position 15. doing.

  The front end side surface of the locking projection 80 is composed of a vertical surface 80a perpendicular to the extending direction of the swing arm 77, while the upper end portion of the base end side side surface is inclined downward toward the base end side. It is composed of a surface 80b. As a result, when the pallet 28 is loaded into the support position 15 located at the standby station A and the locking recess 30 of the pallet 28 and the locking projection 80 of the swinging arm 77 overlap vertically, the swinging arm 77 is The upper end of the locking projection 80 is inserted into the locking recess 30 by swinging upward by the urging force of the tension spring 79. At this time, since the vertical surface 80a of the locking projection 80 comes into surface contact with the vertical surface 30a of the locking recess 30, the pallet 28 is moved rearward (backward in the rotational direction) by the protrusion 29 and the locking projection 80. Is regulated. At this time, the inclined surface 30b of the locking recess 30 and the inclined surface 80b of the locking projection 80 are in surface contact with each other, but since both are inclined surfaces, the pallet 28 is on the front side (forward in the rotational direction). When the movement is attempted, the locking projection 80 is pushed down by the inclined surface 30b, and the movement of the pallet 28 toward the front side cannot be restricted.

  2, 5, and 6, a guide block 84 is fixed to the rotary table 11 between the support member 19 and the conveyance guide 25 at each support position 15, and a plurality of guides extending in the vertical direction are provided on these guide blocks 84. A rod 85 is slidably inserted. An abutting member 86 is fixed to the upper end of the guide rod 85 so that the stopper 32 provided on the lower surface of the pallet 28 can abut. The abutting member 86 is interposed between the abutting member 86 and the guide block 84. A spring 87 is disposed to urge the upper side toward the upper side. Reference numeral 88 denotes a horizontal release plate fixed to the lower end of the guide rod 85. The release plate 88 abuts against the guide block 84 to define the ascent limit of the abutment member 86. Further, the release plate 88 extends toward the outer edge of the turntable 11 while being orthogonal to the transport guide 25, and its tip protrudes radially outward from the outer periphery of the turntable 11. Here, when the pallet 28 is carried into the support position 15 when the abutting member 86 is located at the upper limit, the stopper 32 of the pallet 28 abuts against the abutting member 86 and the pallet 28 Movement to the front side (forward in the rotational direction) is restricted.

  When the pallet 28 is thus loaded into the support position 15 located at the standby station A, the stopper 32 of the pallet 28 comes into contact with the contact member 86 and the movement of the pallet 28 toward the front side is restricted. When the upper end portion of the locking projection 80 is inserted into the locking recess 30 formed on the protrusion 29 of the pallet 28 and the vertical surface 80a comes into contact with the vertical surface 30a, the rearward movement of the pallet 28 is restricted. The pallet 28 is temporarily fixed to the support position 15 of the rotary table 11. Here, the swing arm 77, the tension spring 79, the locking projection 80, the guide block 84, the guide rod 85, the abutting member 86, the spring 87, and the release plate 88 described above are supported by the respective support positions 15 of the turntable 11.

  The temporary fixing of the pallet 28 to the rotary table 11 is recovered as described later after the pallet 28 on which the stacked body 35 is placed is loaded into the support position 15 located at the standby station A. This is performed until the pallet 28 on which the holders 36 are stacked is unloaded from the rotary table 11. In the present invention, the temporary fixing mechanism is constituted by a recess provided in the pallet and a cylinder provided in the rotary table, and the piston rod of the cylinder is protruded and inserted into the recess so that the pallet Temporary fixing may be performed.

  In FIGS. 1 and 2 again, reference numeral 93 denotes a supply means such as a handling robot installed on the floor surface 13 radially outside the rotary table 11 between the supply station B and the collection station C. The supply means 93 has a hand 95 attached to the tip of the articulated arm 94. The supply means 93 includes, from the stacked body 35 placed on the pallet 28 on the support position 15 located at the supply station B, the holder 36 positioned at the uppermost stage and the filler 37 supported by the holder 36. After the attached bead 38 is grasped and taken out by the hand 95, the articulated arm 94 is swung and expanded and contracted, and is once supplied to the pallet 28 on the support position 15 located at the collection station C. Is placed on the holder 36). Thereafter, the supply means 93 removes only the beads 38 with the filler 37 from the pallet 28 of the collection station C, thereby leaving the holder 36 on the pallet 28 of the collection station C, while supplying the removed bead 38 with the filler 37. A means 93 is supplied to a tire intermediate body 96 waiting on the opposite side of the rotary table 11 from the means 93.

  Here, the tire intermediate 96 is constituted by, for example, a cylindrical carcass band formed by winding tire constituent members such as an inner liner and a carcass ply around a cylindrical forming drum 99 one after another, and the filler 37 The bead 38 is fitted to the outer side of the tire intermediate body 96 at one end in the axial direction. After that, the supply means 93 operates in the same manner as described above to take out the holder 36 and the bead 38 with the filler 37 from the uppermost stage of the stacked body 35 in the supply station B, and once stacked on the pallet 28 in the collection station C, Only the bead 38 with the filler 37 is taken out and fitted to the outside of the other end portion in the axial direction of the tire intermediate body 96. In the present invention, the bead 38 with the filler 37 is taken out from the stacked body 35 by the supply means 93 and supplied to the tire intermediate 96, and then the holder 36 supporting the bead 38 with the filler 37 is removed from the collection station C. It may be stacked on the pallet 28 and collected.

  When the bead 38 with the filler 37 is thus supplied to the outside of both ends in the axial direction of the tire intermediate body 96, the forming drum 99 and the tire intermediate body 96 are carried out to the next step. Then, the beads 38 with fillers 37 are successively taken out from the stacked body 35 of the supply station B and supplied to the tire intermediate body 96, and when the pallet 28 on the support position 15 located in the supply station B becomes empty, The rotation driving means 41 rotates the rotary table 11 around the rotation axis to move the support position 15 supporting the pallet 28 on which the stacked body 35 is placed from the standby station A to the supply station B and The support position 15 supporting the pallet 28 is moved from the supply station B to the collection station C.

  As described above, the supply means 93 takes out the bead 38 with the filler 37 and the holder 36 from the pallet 28 and the stacked body 35 on the support position 15 located at the supply station B, and the bead 38 with the filler 37 is removed from the tire intermediate 96. On the other hand, by supplying the holder 36 to the pallet 28 on the support position 15 located in the collection station C, the holder 36 is sequentially stacked on the pallet 28 and collected. At this time, since the temporary fixing mechanism 90 for temporarily fixing the pallet 28 to the rotary table 11 is provided at each support position 15 of the rotary table 11 as described above, the pallet 28 remains at the support position 15 even if the rotary table 11 rotates. As a result, the positional deviation does not occur, and as a result, the take-out of the bead 38 with the filler 37 and the holder 36 by the supply means 93 can be performed smoothly without failure.

  In FIGS. 1 and 6, reference numeral 101 denotes a bracket installed on the floor 13 at a position slightly ahead of the collection station C in the rotational direction and slightly away from the outer periphery of the rotary table 11 in the radial direction. A release cylinder 102 as a release mechanism extending in the vertical direction is fixed to the piston rod 103 of the release cylinder 102, while the pallet 28 on the support position 15 located at the supply station B is emptied, while the collection station When all the holders 36 are stacked and collected on the pallet 28 on the support position 15 located at C, the release plate 88 in the collection station C is pushed down and pushed down. As a result, the abutting member 86 is lowered, and the temporary fixing to the pallet 28 at the collection station C is released, and the pallet 28 can be moved forward in the rotational direction of the rotary table 11.

  In FIG. 1 again, reference numeral 107 denotes a guide body which is installed on the floor 13 behind the collection station C and has the same structure as the guide body 18. The guide body 107 is a support position 15 located at the collection station C. It extends along an extension line of the guide body 18 installed in the. On the floor surface 13 on both sides of the guide body 107, transport guides 108 and 109 having the same structure as the transport guides 24 and 25 are installed, and these transport guides 108 and 109 are supported at the collection station C. 15 extends along an extension line of the conveyance guides 24 and 25 installed at 15. A plurality of pallets 28 on which the collected holders 36 are stacked are placed on the conveyance guides 108 and 109. At this time, each pallet 28 supports the conveyance guides 108 and 109. While being supported from below by the rollers, the ridges 29 of each pallet 28 are engaged (rolling contact) from both sides by the guide rollers constituting the guide body 107, thereby restricting the moving direction of the pallet 28. The guide body 107 and the conveyance guides 108 and 109 described above constitute a discharge means 110 that discharges the pallet 28 on which the collected holders 36 are stacked.

   112 is an unloading means installed on the floor 13 on the right side of the rotary table 11. The unloading means 112 has a support plate 113 that is fixed to the floor 13 and extends parallel to the transfer guide 109. The support plate 113 is provided with a transfer mechanism 114 having the same structure as the transfer mechanism 73. The carry-out means 112 operates in the same manner as the carry-in means 57, and is on a support position 15 located at any station between the collection station C and the standby station A, in this embodiment the collection station C. The pallet 28 is unloaded from the rotary table 11 together with the collected holders 36 stacked to an empty unloading position F set at the front ends of the conveyance guides 108 and 109. Reference numeral 117 denotes a transport carriage capable of transporting one pallet 28 loaded with the stacked body 35. The transport carriage 117 transports the pallet 28 on which the stacked body 35 is placed to immediately after the transport guides 54 and 55. Can do. In the present invention, a cylinder for pulling the pallet into the carry-out position F, a rack and pinion mechanism, or the like may be used as the carry-out means.

   120 is a support plate that is installed on the floor 13 between the transport guide 54 and the transport guide 108 and extends in parallel with the transport guides 54, 108, on the left side of the support plate 120 close to the transport guide 54. A transfer mechanism 121 having the same structure as that of the transfer mechanism 73 is installed. The transfer mechanism 121 operates when the pallet 28 at the carry-in position E is carried into the support position 15 located at the standby station A by the carry-in means 57, so that the carry carriage 117 is operated when the carry-in position E becomes empty. The upper pallet 28 and the pallet 28 on the conveyance guides 54 and 55 are moved together to feed the pallet 28 at the front end to the loading position E.

  A transfer mechanism 122 having the same structure as the transfer mechanism 73 is installed on the right side of the support plate 120 adjacent to the transport guide 108. The transfer mechanism 122 is configured so that the pallet 28 on which the holder 36 is stacked by the unloading means 112 is unloaded from the collection station C to the unloading position F, and the empty transfer carriage 117 moves immediately after the transfer guides 108 and 109. Then, the pallet 28 on the transport guides 108 and 109 is moved backward integrally, the rear pallet 28 is transferred to the empty transport cart 117, and the pallet 28 is pushed backward from the discharge station F. . Thereafter, the transport carriage 117 supporting the pallet 28 on which the holder 36 is stacked is moved, and the pallet 28 supporting the holder 36 is replaced with the pallet 28 supporting the stacked body 35 at the replacement position. .

Next, the operation of the first embodiment will be described. However, in order to simplify the description, the description will be given focusing on one pallet 28.
Here, attention is paid to the pallet 28 currently located at the carry-in position E. On the pallet 28, a stacked body 35 in which holders 36 and beads 38 with fillers 37 are alternately stacked is placed. . At this time, if the empty support position 15 that does not support anything is positioned at the standby station A, the drive motor 68 of the loading means 57 is activated and the chain 71 travels, and the slider 60 moves to the standby station A. Move forward. During this movement, since the hook 63 engages with the locking piece 31 of one pallet 28 located at the carry-in position E, the pallet 28 on which the stacked body 35 is placed is pushed by the hook 63. Then, it moves forward and is carried onto an empty support position 15 located at the standby station A.

  When the pallet 28 is carried in, the support rollers 27 of the conveyance guides 24 and 25 support the pallet 28 from below while being in rolling contact with the lower surface of the pallet 28, while the guide rollers 20 forming a pair of guide bodies 18 are placed on the pallet 28. It engages while rolling and contacting both side surfaces of the provided ridge 29. Thereby, the moving direction of the pallet 28 is regulated by the extending direction of the guide body 18, and the pallet 28 is reliably guided to the support position 15 located at the standby station A. Further, since the inclined surface 80b of the locking projection 80 is engaged with the ridge 29 during the loading of the pallet 28, the swing arm 77 is pushed by the ridge 29 and the tension spring 79 is attached around the pin 76. While opposing the force, it swings downward to the position indicated by the phantom line in FIG. Thereafter, the pallet 28 moves forward in a state where the upper end of the locking projection 80 and the lower surface of the ridge 29 are in sliding contact with each other. The movement of the pallet 28 is moved to the support position 15 where the pallet 28 is located at the standby station A. When it reaches, the stopper 32 of the pallet 28 comes into contact with the contact member 86 located at the ascending limit, thereby stopping the pallet 28 from moving forward (forward in the rotational direction).

  Simultaneously with the contact of the stopper 32 with the contact member 86 described above, the locking recess 30 and the locking projection 80 overlap vertically, and as a result, the swing arm 77 swings upward by the urging force of the tension spring 79. The upper end portion of the locking projection 80 is inserted into the locking recess 30 by moving. As a result, the vertical surface 80a of the locking projection 80 comes into surface contact with the vertical surface 30a of the locking recess 30, and the movement of the pallet 28 to the rear side (rear in the rotational direction) is restricted. When the pallet 28 is thus carried into the support position 15 located at the standby station A, the pallet 28 is restricted from moving in any direction forward or backward by the temporary fixing mechanism 90 and is temporarily fixed to the rotary table 11. The

  When the pallet 28 of interest mentioned above is carried in from the carry-in position E to the support position 15 located at the standby station A by external setup, the supply means 93 is supplied to the supply station B in the supply station B and the collection station C. After the upper body holder 36 and the bead 38 with the filler 37 supported by the holder 36 are gripped by the hand 95 and taken out from the stacked body 35 placed on the pallet 28 on the support position 15 positioned. Then, the articulated arm 94 is swung and expanded and contracted, and once supplied to the pallet 28 on the support position 15 located at the collection station C, the pallet 28 (if the holder 36 is already mounted, the holder 36 Top).

  Thereafter, the supply means 93 removes only the bead 38 with filler 37 from the pallet 28 of the collection station C, leaving the holder 36 on the pallet 28 of the collection station C, and placing the holder 36 on the pallet 28 in the collection station C. Collect by sequentially stacking. At this time, the taken-out bead 38 with the filler 37 is supplied to the tire intermediate body 96 by the supply means 93 and set outside one end portion in the axial direction thereof. After that, the supply means 93 operates in the same manner as described above to take out the uppermost holder 36 and the bead 38 with the filler 37 from the stacked body 35 in the supply station B, and once stacked on the pallet 28 in the collection station C, Only the bead 38 with the filler 37 is taken out and set outside the other axial end of the tire intermediate body 96. In this way, when the pair of beads 38 with the filler 37 is supplied to the outer sides of both ends of the tire intermediate body 96 in the axial direction, the forming drum 99 and the tire intermediate body 96 are carried out to the next step.

  When the pallet 28 on the support position 15 located at the supply station B is emptied by the supply means 93 performing the above-described operation repeatedly, the unloading means 112 is activated and the support located at the collection station C is supported. The pallet 28 on the position 15 is unloaded together with the collected holder 36 from the turntable 11 (rotation station C) to an empty unloading position F. Next, when the drive motor 47 of the rotation drive means 41 is actuated to rotate the external gear 44, the rotary table 11 having the external teeth 42 meshed with the external gear 44 rotates around the rotation axis, and attention is paid to it. The pallet 28 and the support position 15 supporting the pallet 28 are moved from the standby station A to the supply station B separated by the same angle as the angle between the support positions 15. Thus, when the turntable 11 is rotated by the same angle as the angle between the support positions 15, the support position 15 supporting the empty pallet 28 is transported from the supply station B to the collection station C, and the pallet 28 is carried out. The empty support position 15 from the collection station C to the empty station D, and the empty support position 15 from the empty station D to the standby station A simultaneously with the pallet 28 of interest. Moving. In this embodiment, the empty station D is an idle station, and nothing is done.

  When the noted pallet 28 moves to the supply station B by the rotation of the rotary table 11, the supply means 93 operates in the same manner as described above, and the holder 36 is moved from the stacked body 35 on the pallet 28 in the supply station B. The beads 38 with fillers 37 are taken out one after another, and the beads 38 with fillers 37 are supplied to the tire intermediate 96, while the holders 36 are sequentially stacked on the pallet 28 in the collection station C and collected. Thus, during the period in which the bead 38 with filler 37 is supplied to the tire intermediate body 96 by the supply means 93, the pallet 28 located at the carry-in position E is supported at the standby station A by the carry-in means 57. It is carried in position 15 on the outside setup.

  When the supply means 93 repeatedly performs the above-described operation, when the pallet 28 of interest in the supply station B becomes empty, the unloading means 112 is activated and the holder 36 in which the pallet 28 in the recovery station C is recovered. At the same time, it is unloaded to the unloading position F. Thereafter, the rotary table 11 is rotated around the rotation axis by the operation of the rotation driving means 41, and the empty pallet 28 of interest is moved to the collection station C. Next, the supply means 93 successively takes out the holders 36 and the beads 38 with the fillers 37 from the stacked bodies 35 on the pallet 28 in the supply station B in the same manner as described above, and supplies the beads 38 with the fillers 37 to the tire intermediate body 96. The holders 36 are sequentially stacked on the pallet 28 of interest of the collection station C and collected. At this time, the pallet 28 supporting the stacked body 35 is carried by the carry-in means 57 from the carry-in position E onto the support position 15 of the standby station A by external setup.

  After that, the supply means 93 repeatedly performs the above-described operation, so that the pallet 28 in the supply station B is emptied, and is released when the holder 36 is stacked on the pallet 28 of interest in the collection station C until the holder 36 is full. The piston rod 103 of the cylinder 102 protrudes, and the release plate 88 and the contact member 86 of the temporary fixing mechanism 90 at the collection station C are pushed down against the spring 87 to release the temporary fixation of the stopper 32 by the contact member 86. As a result, the pallet 28 of interest can be moved forward (rear side) in the rotational direction. In this state, the unloading means 112 is operated, and the pallet 28 of interest is unloaded from the rotary table 11 (collection station C) to the unloading position F together with the holder 36 that has been collected. Thereafter, when the rotary table 11 rotates around the rotation axis by the operation of the rotation driving means 41, the supply of the beads 38 with the filler 37 to the tire intermediate body 96 by the supply means 93 is resumed. Each time the pallet 28 in the supply station B becomes empty by the operation of the supply means 93, the rotary table 11 is rotated, and each support position 15 and the pallet 28 are sent to the next station.

  In this way, the rotary table 11 is provided with support positions 15 corresponding to at least three stations including the standby, supply and recovery stations A, B and C, and the filler 37 from the stacked body 35 on the pallet 28 located at the supply station B. The bead 38 with the holder 38 and the holder 36 are taken out and the bead 38 with the filler 37 is supplied to the tire intermediate 96, while the holder 36 is sequentially stacked on the pallet 28 located at the collection station C and collected. When the bead 38 with 37 and the holder 38 are repeatedly taken out and the pallet 28 located at the supply station B becomes empty, the pallet 28 on which the holder 36 is stacked is unloaded from the collection station C of the turntable 11 by the unloading means 112. To do. Thereafter, the rotary table 11 is rotated around the rotation axis by the rotation driving means 41, and the pallet 28 located at the standby station A is supplied to the supply station B together with the stacked body 35. The empty pallet 28 is supplied to the supply station B. From the empty station D to the standby station A, respectively.

  As a result, the stacked body 35 is supplied to the supply station B together with the pallet 28, and the supply of the bead 38 with the filler 37 to the tire intermediate body 96 can be resumed. Then, the pallet 28 on which the stacked body 35 is placed is loaded onto the empty support position 15 located at the standby station A by the loading means 57. Thus, in this embodiment, when the supply of the bead 38 with the filler 37 to the tire intermediate 96 is resumed, the pallet 28 supporting the recovered holder 36 is unloaded from the turntable 11 (collection station C). Since the turntable 11 is rotated, two steps are required. However, since three steps were required in the past, the number of steps can be reduced by one, thereby allowing the work to be performed with a simple structure. Efficiency can be improved easily.

  The supply to the loading position E of the pallet 28 on which the stacked body 35 is placed is, for example, every time a new pallet 28 on which the stacked body 35 is mounted is supplied immediately after the supply means 56 by the transport carriage 117. The transfer mechanism 121 is operated to move all the pallets 28 on the supply means 56 forward, and the pallet 28 at the front end is moved to the loading position E, while the unloading position F is emptied. For example, every time the empty transport cart 117 is moved immediately after the discharge means 110, the transfer mechanism 122 is operated to move all the pallets 28 on the discharge means 110 rearward and are positioned at the rear end. This can be done by transferring one pallet 28 to the empty transport cart 117.

  Next, the feeding / discharging means 125 is moved by one pitch, and the pallet 28 on which the stacked body 35 is placed is conveyed to a position facing the standby station A. Thereafter, the pallet 28 on which the stacked body 35 is placed is carried by the carry-in / out means 126 from the supply / discharge means 125 onto the empty support position 15 located at the standby station A. In this way, after the bead supply operation to the tire intermediate body is resumed, the pallet 28 supporting the recovered holder 36 is replaced with the pallet 28 supporting the stacked body 35 by the loading / unloading means 126 by external setup. For example, the supply of the bead to the tire intermediate body can be resumed by only one step of the rotation of the turntable 11. As a result, the work efficiency can be improved reliably and easily with an extremely simple configuration. However, in the case of this embodiment, interference may occur between the loading / unloading means 126 and the stacked body 35 and the holder 36 when the turntable 11 is rotated and when the supply / discharge means 125 is operated. There may be a need for another mechanism such as retreating the means 126 upward, for example.
