As shown in FIGS. 1 and 3, the transport facility 10 transports the cart 12 to the unloading section R <b> 1 from the upstream side to the downstream side in the transport direction of the plurality of carts 12 loaded with the bead members 1. 1 transport mechanism 30A, an unloading device 40 for unloading the bead member 1 from the cart 12 located in the unloading section R1, and an empty cart 12 after the bead member 1 is unloaded to the downstream side. The second transport mechanism 30B is configured so that the entire transport path is, for example, L-shaped. As shown in FIG. 1, in the following description, for convenience, the plurality of carriages 12 may be described as 12A; 12B; 12C; 12D; 12E from the downstream side to the upstream side in the transport direction.

[About transported objects]
As shown in FIGS. 1 and 3, the carriages 12 </ b> A to 12 </ b> E transported by the transport facility 10 are connected to each other via a connecting means 50 described later along the transport direction. A plurality of bead members 1 serving as objects to be conveyed are loaded on the carriages 12C to 12E located on the upstream side of the unloading section R1. The plurality of bead members 1 loaded on the trolleys 12C to 12E are unloaded by the unloading device 40 when the trolleys 12C to 12E reach the unloading section R1, and are used for the next process such as a tire molding drum (not shown). Be transported. In particular, as shown in FIG. 3, each carriage 12 is loaded with cartridges 16 and bead members 1 placed on the cartridges 16 so as to be alternately stacked. The cartridge 16 is a plate-like partition member formed in a circular shape in plan view, and separates the bead members 1 according to the specifications of the tire and prevents the bead members 1 from adhering to each other.

[About connecting means]
Next, the connecting means 50 for connecting the carriages 12A to 12E will be described. As particularly shown in FIG. 2, the connecting means 50 includes a connecting portion 50 </ b> A extending from the downstream side in the conveying direction of each carriage 12 toward the downstream side, and from the upstream side to the upstream side in the conveying direction of each carriage 12. And the connecting portion 50B extending so as to be engaged with each other. The connecting portions 50 </ b>A; 50 </ b> B have a horizontal portion 51 that is fixed to the carriage 12 at one end and extends horizontally in a direction away from the carriage 12. A curled portion 53 that curves downward is formed on the downstream side of the horizontal portion 51 in the connecting portion 50A. Further, a curled portion 55 that curves upward is formed on the upstream side of the horizontal portion 51 in the connecting portion 50B. The curled portions 53; 55 can be engaged with each other with their inner peripheral surfaces in contact with each other. For example, the carriage 12A located on the downstream side extends along the extending direction of the connecting portions 50A; 50B. When transported, the curl portions 53; 55 are not disengaged from each other, and the downstream carts 12B to 12E move downstream in connection with the transport of the cart 12A. On the other hand, when the cart 12A located on the downstream side is conveyed in a direction intersecting (orthogonal) on the same plane as the extending direction of the connecting portions 50A; 50B, the engagement between the curled portions 53; 12A is separated from the carts 12B to 12E on the downstream side and can move alone. Based on the above, the transporting process of the carriages 12A to 12E by the transporting facility 10 will be described below.

[About transport process and transport equipment]
The transfer facility 10 is installed on the floor surface 11. As shown in FIG. 3, a guide portion 21 that guides the wheels 13 of each carriage 12 is formed on the floor surface 11. The guide portion 21 is a concave portion slightly recessed downward from the floor surface 11 and extends in an L shape along the conveying direction of each carriage 12. A wheel 13 pivotally supported by a caster (not shown) is attached to the lower surface of each carriage 12, and moves in the guide portion 21 toward the downstream side whenever a first transport mechanism 30A described later is driven. To do.

As shown in FIG. 1, the carriage 12 transported by the transport facility 10 according to the present embodiment is an object to be transported as a first path including an unloading section R1 and a cartridge collection section R2 in order from the upstream side to the downstream side. Via the collection path L1, it is conveyed linearly to a connection release section R3 provided on the downstream side of the conveyed object collection path L1. Further, the carriage 12 transported to the connection release section R3 is released from the subsequent carriage 12 and is transported alone so as to traverse the carriage collection path L2. Here, the connection release section R3 is a buffer section provided between the transported object collection path L1 and the carriage collection path L2, and in this section, the subsequent section is driven in parallel with the driving of the unloading device 40 described later. The connection with the carriage 12 is released, and the carriage to the carriage collection path L2 is performed.
In FIG. 4A, a carriage 12A is a carriage located in the cartridge collection section R2. The bead member 1 is not loaded on the cart 12A because it has already passed through the upstream unloading section R1. On the other hand, the cartridge 16 loaded on the cart 12B located in the upstream unloading section R1 is loaded on the cart 12A by driving the unloading device 40.

[Unloading device]
As shown in FIGS. 1 and 3, the bead member 1 is unloaded from the cart 12 (cart 12 </ b> B) that has reached the unloading section R <b> 1 by driving the unloading device 40, and interposed in each bead member 1. The cartridge 16 to be transferred is transferred.

  The unloading device 40 includes a rectangular base 41 installed on the floor 11. A revolving body 42 is provided on the upper surface of the base 41, and the positions of the arms 43; 45 and the hand 46 extending from the revolving body 42 are arbitrarily controlled by the revolving operation of the revolving body 42. One end of the arm 43 is attached to the upper surface of the revolving body 42. The arm 43 is a shaft that extends upward from the upper surface of the revolving body 42, and can be tilted at an arbitrary angle with respect to the floor surface 11. An arm 45 is attached to the other end of the arm 43 via a joint 44. The arm 45 is a shaft having a smaller diameter than the arm 43, and can be tilted at an arbitrary angle with respect to the arm 43 by the rotation of the joint portion 44.

  A disc-shaped hand 46 is slidably attached to the other end of the arm 45. A grip portion 47 that can grip the bead member 1 and the cartridge 16 is provided on the lower surface of the hand 46. The grip portion 47 is formed of, for example, a magnet or a suction cup, and can grip the bead member 1 and the cartridge 16 by a magnetic force, an attractive force, or the like.

  As shown in FIG. 1, the hand 46 of the unloading apparatus 40 is provided with a carriage 12B located in the unloading section R1 and a tire molding drum (not shown), etc., by the revolving operation of the revolving body 42 and the arms 43; After reciprocating between the facilities related to the next process and between the carriage 12B and the carriage 12A located in the cartridge recovery section R2, the plurality of bead members 1 loaded on the carriage 12B are transferred to the next process side and after use. The plurality of cartridges 16 are transferred to the carriage 12A side located in the downstream cartridge recovery section R2.

  When the unloading device 40 is driven, the unloading of the bead member 1 on the carriage 12B is completed to become an empty carriage, and when all the used cartridges 16 are transferred to the downstream carriage 12A, they are moved to the most downstream side. The positioned carriage 12A is transported to a connection release section R3 provided downstream of the cartridge collection section R2 by driving the first transport mechanism 30A. Hereinafter, the first transport mechanism 30A will be described.

[About the first transport mechanism]
As shown in FIGS. 1 and 3, the transport mechanism 30A as a moving mechanism is an apparatus that extends from a part of the unloading section R1 to the entire area of the cartridge collection section R2 and a part of the connection release section R3. Thus, the carriage 12A located in the cartridge collection section R2 is transported toward the downstream connection release section R3.
The transport mechanism 30 </ b> A includes a support plate 32 that extends in parallel with the guide portion 21 formed on the floor surface 11. A guide rail 33 extending along the extending direction of the support plate 32 is disposed on the side of the support plate 32 facing the carriage 12. A slider 34 is slidably disposed on the guide rail 33. The slider 34 is a substantially trapezoidal plate piece that is orthogonal to the guide rail 33 and extends toward the carriage 12 side.

  On one end side of the slider 34, a meshing portion (not shown) that meshes with a gear 36 </ b> A of the motor 35 disposed on both sides of the guide rail 33 and a chain 37 spanned over the gear 36 </ b> B is formed. When the slider 34 meshes with the chain 37 via a meshing portion (not shown), the slider 34 is guided by the guide rail 33 according to the rotation of the chain 37 by forward and reverse driving of the motor 35, and the extending direction of the guide rail 33, That is, reciprocation is possible across the upstream and downstream sides in the transport direction.

  As shown in the enlarged view of FIG. 1, a pressing portion 34 </ b> D that contacts the upstream side of the carriage 12 </ b> A is formed on the downstream end surface of the slider 34. When the slider 34 moves from the upstream side to the downstream side, the pressing portion 34D presses the upstream side of the carriage 12A and pushes the carriage 12A located in the cartridge recovery section R2 to the downstream connection release section R3. As shown in the figure, the slider 34 has a base portion 34A and a middle bent portion 34B along the extending direction toward the carriage 12 side. The base 34A and the middle bent portion 34B are connected by a spring-equipped hinge 34C disposed on the pressing portion 34D side. When the slider 34 moves from the upstream side to the downstream side, the base 34A and the middle bent portion 34B are connected. While 34B is maintained linearly, when moving from the downstream side to the upstream side, the middle bent portion 34B returns in a state where it is bent downstream. With such a configuration, in the forward path in which the slider 34 moves from the upstream side toward the downstream side, the carriage 12 located in the cartridge recovery section R2 is pushed out to the connection release section R3, and from the downstream side toward the upstream side. In the returning path which moves, it returns to an upstream side, without interfering with the trolley | bogie 12 located in connection cancellation | release area R3.

  As shown in FIG. 1B, when the carriage 12A is conveyed to the disconnection section R3 by driving the first conveyance mechanism 30A, the subsequent carriage 12B connected to the carriage 12A is recovered from the unloading section R1. The subsequent carriage 12C that moves to the section R2 and continues to the carriage 12B moves to the unloading section R1 from the upstream side of the unloading section R1. After the movement, unloading of the bead member 1 on the carriage 12C newly moved to the unloading section R1 is started, and the cartridge 16 is moved to the carriage 12B newly moved to the cartridge collection section R2. Loading begins.

[Second transport mechanism]
On the other hand, the carriage 12A conveyed to the disconnection section R3 is conveyed onto the carriage collection path L2 by the second conveyance mechanism 30B. The second transport mechanism 30B is a device having the same configuration as the first transport mechanism 30A. In this example, the movement direction of the slider 34 is the movement direction of the slider 34 of the first transport mechanism 30A. It is provided so that it may become a direction which intersects. That is, the second transport mechanism 30B is configured so that, in the connection release section R3, the carriage 12A that has passed through the linearly extending transported object recovery path L1 intersects the extending direction of the transported object recovery path L1 (this example). In this case, the sheet is conveyed downstream so as to be extruded in a direction orthogonal to the above. Further, the connection between the connecting portion 50B of the carriage 12A and the connecting portion 50A of the succeeding carriage 12B is released by pushing in the direction intersecting with the extending direction of the transported object collection path L1. Then, the carriage 12A is conveyed to the carriage collection path L2 side while being separated from the following carriages 12B to 12E. The carriage collection path L2 as the second conveyance path is provided on the downstream side of the connection release section R3 (immediately after being conveyed by the second conveyance mechanism 30B), and collects the carriage 12 on which the cartridge 16 is loaded.

  Further, the carriage 12A is transported to the carriage collection path L2 side to unload the bead member 1 on the carriage 12C newly moved to the unloading section R1 and to the carriage 12B newly moved to the cartridge collection section R2. This is performed before the transfer of the cartridge 16 is completed, and when the unloading of the bead member 1 and the transfer of the cartridge 16 are completed, an empty space in which the carriage 12 does not exist in the connection release section R3. Then, as shown in FIG. 1C, a new carriage 12B in which the transfer of the cartridge 16 has been completed in the cartridge recovery section R2 is transported to the connection release section R3 that has become the empty space.

  Thereafter, the unloading process of the bead member 1 performed substantially simultaneously in the unloading section R1 and the cartridge recovery section R2, the transfer process of the cartridge 16, and the uncoupling section R3 performed during the unloading process and the transfer process. By repeating a cycle consisting of the connection release of the carriage 12 and the conveyance process to the carriage collection path L2, and the conveyance process to the connection release section R3 that is an empty space of the carriage after the unloading process and the transfer process are completed. The carriage 12 sequentially moves on the conveyance path.

In the present embodiment, the unloading section R1 and the cartridge collection section R2 are provided adjacent to each other on the conveyed object collection path L1 extending linearly, and in other words, on the downstream side of the cartridge collection section R2, in other words, By providing a connection release section R3 as an empty space between the transported object collection path L1 and the carriage collection path L2, when the carriage 12 moves to the unloading section R1 and the cartridge collection section R2, the downstream side Regardless of the presence of the existing carriage 12 (eg, the carriage 12A in the illustrated example), the unloading process and the cartridge recovery process by driving the unloading device 40 can be started immediately, and the tire in the next process requiring the bead member 1 can be started. Production efficiency can be improved.
In the present embodiment, the carriage 12 located in the cartridge collection section R2 and the carriages 12 located on the upstream side of the carriage 12 are connected to each other by the connecting means 50, so that the carriage 12 is located in the cartridge collection section R2. The upstream cart 12 can be moved to the downstream side only by pushing the cart 12 to be pushed. In addition, since the stroke range of the slider 34 of the first transport mechanism 30A can be set to about the size in the transport direction of one carriage 12, the transport mechanism can be reduced in size and space can be saved.

FIG. 4 is a schematic plan view showing an outline of a transport facility 10 ′ according to another embodiment.
The transport facility 10 according to the above embodiment has a substantially L-shaped device shape as a whole, whereas the transport facility 10 'shown in FIG. Different from form.

[About the third transport mechanism]
The conveyance facility 10 ′ includes a third conveyance mechanism 30C in addition to the configuration of the conveyance facility 10 according to the embodiment. The third transport mechanism 30C is an apparatus having the same configuration as the first transport mechanism 30A and the second transport mechanism 30B, and in this example, the moving direction of the slider 34 is the first transport mechanism. It is provided so as to be in a direction opposite to the moving direction of the slider 34 of 30A (direction intersecting the moving direction of the slider 34 of the second transport mechanism 30B). That is, the third transport mechanism 30C moves the cart 12 (cart 12A) transported from the connection release section R3 to the cart recovery path L2 by the second transport mechanism 30B in the direction opposite to the extension direction of the transported object recovery path L1. (Transverse direction with respect to the moving direction of the slider 34 of the second conveyance mechanism 30B)
Further, the carriage 12A is transported to the carriage collection path L2 side to unload the bead member 1 on the carriage 12C newly moved to the unloading section R1 and to the carriage 12B newly moved to the cartridge collection section R2. This is performed before the transfer of the cartridge 16 is completed, and when the unloading of the bead member 1 and the transfer of the cartridge 16 are completed, the carriage 12 does not exist on the carriage collection path L2. And the 3rd conveyance mechanism 30C sends out to the downstream side, whenever a new cart 12B is conveyed.

  As described above, the transport facility 10 ′ according to the present embodiment has the same effects as the transport facility 10. Further, since the transport facility 10 ′ includes the third transport mechanism 30 </ b> C, the transport direction of the carriage 12 can be freely controlled. Note that the position, size, and the like of the third transport mechanism 30C are not limited to the example described in the present embodiment, and can be freely changed according to the environment in which the transport facility 10 ′ is installed.

As mentioned above, although this invention was demonstrated through several embodiment, this invention is not limited to the above-mentioned embodiment. In addition, it is naturally possible to combine the configurations according to the above embodiments.
For example, although the transport facility 10; 10 ′ of the present embodiment has been described on the assumption that the bead member 1 is transported, the transported object is not limited to the bead member 1. Further, in the transport facility 10; 10 ′, the bead members 1 and the cartridges 16 are alternately stacked on the carriage 12, and the unloading device 40 unloads the bead members 1, and the cartridge 16 is placed in the cartridge collection section R 2.
