Description

  The present invention relates to a connection structure and an article guidance system including the connection structure, and more particularly, to a connection structure used for automatic conveyance in an article placement site such as a parking lot and an article guidance system including the connection structure.

  In recent years, automatic parking has become a theme in parking lots. There has already been proposed a car parking system for performing automatic parking in a car parking lot.

  That is, one of the conventionally proposed car parking systems is to place a car to be parked on a pallet and transport the pallet together with the car by a belt conveyor or the like between a parking lot entrance and a storage position (patent) Reference 1).

  Moreover, another one of the conventionally proposed car parking systems is to carry a car to be parked on a cage and suspend the car with a hoist between a parking lot entrance and a storage position. Yes (see Patent Document 2).

Japanese Examined Patent Publication No. 7-33730 (pages 3 to 5, Fig. 1) JP-A-4-285273 (second page, FIG. 1)

  However, these conventional parking systems for automobiles have a problem that heavy equipment is required for transporting automobiles. Assuming that automobiles are loaded with a large amount of cargo, belt conveyors and hoists that carry pallets and cages while carrying heavy vehicles are inevitably large in size and inevitably require heavy equipment. It will take.

  In addition, in the case of the former car parking system, the installation of the belt conveyor is practically not a floor-free structure. If it is not a floor-free structure, floor construction will be required at the time of system installation, and safety measures will be required for the facilities on the floor even after construction.

  Therefore, the present invention has been made in view of the actual situation of the above-described conventional technology, and the problem is that in addition to being able to carry articles such as automobiles with light equipment, a floor-free structure is possible in practice. It is an object of the present invention to provide a connection structure and an article guidance system including the connection structure.

  The above-mentioned subject is achieved by the invention described in each claim. That is, the characteristic structure of the connection structure according to the present invention is an unmanned induction machine that moves back and forth along the guide rail while being engaged with the guide rail, and a self-propelled type that travels on its own by placing the article to be conveyed. In the structure for connecting the carriage, the unmanned induction machine and the self-propelled carriage are mechanically connected to each other so as to be separable, and the mechanical connector includes a built-in electric circuit. The self-propelled carriage can be mounted on a cart or an unmanned induction machine, and the self-propelled carriage can be moved according to the guidance of the unmanned induction machine.

  According to this configuration, since the articles to be transported are transported by a self-propelled cart that travels by self-propelled, the goods can be transported by light equipment, and an unmanned induction machine that guides the self-propelled cart or for guidance Since the rail can be arranged and installed above the floor of the article placement site, and the mechanical connector is mounted on the self-propelled carriage or the unmanned induction machine, a floor-free structure can be achieved in practice.

  As for the self-propelling mechanism of the self-propelled carriage, an electric traveling mechanism such as an electric motor is conceivable. However, in order to travel on its own by the electric traveling mechanism, the floor for storing and storing the articles to be transported is stored. A power supply / signal rail is installed above the motor, and this is connected to the electric traveling mechanism of the self-propelled carriage with an electrical connector. The power required for the self-propelled carriage to travel from the power supply / signal rail It is possible to adopt a method such as traveling along the guide route of the article while receiving the goods. Self-propelled carts can always supply the energy necessary for self-driving, and in addition to the power supply / signal rails being installed above the floor of the article storage area, the electric circuit connector is also a self-propelled cart or Since it is mounted on an unmanned induction machine, the floor-free structure will not be damaged.

  As a result, it is possible to provide a connection structure that enables a floor-free structure in addition to being able to transport articles to be transported such as automobiles with light equipment.

  The induction machine side connection part is attached to the unmanned induction machine side, the carriage side connection part is attached to the self-propelled carriage side, and the electric circuit is incorporated in each induction machine side connection part. It is preferable that mechanical connection and electrical circuit connection are made by the engagement of the connecting part with the carriage side.

  According to this configuration, the unmanned induction machine and the self-propelled carriage can be mechanically connected simply by engaging the induction machine side connection part and the carriage side connection part of the mechanical connection unit, and the mechanical connection unit The unmanned induction machine and the self-propelled carriage can be mechanically separated simply by disengaging the induction machine side connection part and the carriage side connection part.

  It is preferable that the connector of the induction machine side connection part and the cart side connection part can be rotated horizontally by a remote operation by a signal.

  According to this configuration, in addition to the direction change of the carriage, it is possible to change the direction of only both connection parts and, in some cases, only the induction machine side connection part. There are cases where it is necessary to change the direction of the induction machine from the structure of the connector because the induction machine travels only along the guidance rail. When the induction machine has completed storage at the storage position, when the carriage at the opposite storage position is withdrawn, or at the article storage entrance, the induction machine side connection part may get stuck, or the induction machine side connection may not be possible. Even in such a case, the horizontal rotation mechanism is activated by issuing a signal by remote control, and the induction machine side connection part and the carriage side connection part Can be integrally rotated 180 degrees horizontally and separated from each other, that is, can be withdrawn. Moreover, only the induction machine side connection part can be prepared for the next connection by changing the direction by 180 degrees.

  In addition, the characteristic configuration of the article guidance system according to the present invention includes a guidance rail installed along the guidance path of the article to be transported above the article placement floor, and a guidance rail while being engaged with the guidance rail. And an unmanned induction machine that travels along the line, and a trackless self-propelled carriage that carries the article to be transported and travels between the article storage area entrance and the storage position of the placed article by itself. The unmanned induction machine and the self-propelled carriage are connected by the connection structure according to any one of claims 1 to 3.

  When an article such as an automobile is received by the article guidance system of the present invention (hereinafter abbreviated as “guidance system” as appropriate), the article to be transported is placed on the self-propelled carriage at the entrance of the article placement site, and unmanned guidance is performed. The machine and the self-propelled carriage are mechanically connected by a mechanical connector. The self-propelled carriage follows the guidance of the unmanned induction machine for each article in conjunction with the unmanned induction machine moving to the storage position for the placed article along the guidance rail installed above the floor of the article placement site. As guided by the unmanned guidance machine, it proceeds to the storage position of the placed article along the guidance route. Then, after the self-propelled carriage arrives at the storage position, when the mechanical connection by the mechanical connector is disconnected and the unmanned induction machine is disconnected from the self-propelled carriage, the goods are completely received by the self-propelled carriage. .

  When an article is delivered by the guidance system of the present invention, the unmanned guidance machine and the self-propelled carriage are first mechanically connected by a mechanical connector at the storage position of the placed article. Then, in conjunction with the unmanned guidance machine moving along the guidance rail to the exit of the article placement site, the self-propelled carriage is guided by the unmanned guidance machine according to the guidance of the unmanned guidance machine along with the guidance route. To the exit of the article placement site. And after the self-propelled carriage arrives at the exit of the article placement site, when the article of the self-propelled carriage advances from the exit to the outside of the article placement site, the delivery is completed.

  Therefore, according to the article guidance system of the present invention, the article to be transported is transported by the self-propelled carriage that travels between the article placement site entrance and the storage position of the placed article by self-propulsion. Can be done with equipment. In addition to the trackless self-propelled carriage, unmanned induction machines and guidance rails that guide and guide the trackless self-propelled carriage are placed and installed above the floor of the article placement site. Since the mechanical connector is mounted on a self-propelled cart or unmanned induction machine, it is virtually floor-free.

  In addition, according to the present invention, if one unmanned induction machine is provided, a large number of self-propelled carriages can be sequentially conveyed to a predetermined location, so that the manufacturing cost can be reduced while ensuring high convenience.

  It is preferable that a turntable is provided on the floor for placing the article, and the direction change of the self-propelled carriage that carries the article to be transported and runs on its own is possible.

  According to this configuration, the space of the article placement site can be used effectively, and the loaded article can be easily changed in direction with the self-propelled carriage. With the rotation of the turntable, only the self-propelled carriage and the loaded article on the carriage can change direction, and can be carried out in the direction opposite to the direction when the article on the carriage is received. In addition, the direction of the induction machine side connection part and the cart side connection part does not change by this direction change.

  A spare hangar for a self-propelled carriage is installed near the entrance of the article storage site, and a rotating roadbed is provided in a multi-tiered shape inside the hangar, and the self-propelled carriage can be folded. The foldable self-propelled carriage can be stored in the multi-stage shelf-like rotary base plate, and the lower stage of the multi-stage shelf-like rotary base plate can be folded. In addition, it is preferable that the spare self-propelled carriage is disposed on the uppermost stage.

  According to this configuration, a spare self-propelled cart hangar is installed near the entrance of the article placement site, and a spare self-propelled cart is placed in the hangar, so a large number of spare carts and articles are placed. Even if the cart is moved in a complicated manner by the loading / unloading instruction in the article placement site or is forced to make a detour, it is possible to avoid unreasonable movement and quickly and efficiently carry goods. Movement can be achieved.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram illustrating an installation state of the article guidance system according to the present embodiment, and FIG. 2 is an overhead view illustrating an overview of the installation state of the guidance system according to the embodiment.

  The guidance system according to this embodiment is installed along a guidance route of an automobile M that is a kind of article to be transported (sometimes simply an article) above a parking lot floor F that is a kind of article placement site. The guided rail 1, the unmanned guide machine 2 that moves back and forth along the guidance rail while being engaged with the guidance rail, and the parking lot entrance P and the storage position Q of the vehicle on which the automobile M to be transported is placed. A self-propelled bogie 3 that travels between the self-propelled vehicles and a mechanical connector 4 that mechanically connects the unmanned induction machine 2 and the self-propelled cart 3 in a separable manner. The machine 2 and the self-propelled carriage 3 are provided so that they can be mounted.

  In the case of this guidance system, the self-propelled carriage 3 is equipped with the electric traveling mechanism 3A, and is parallel to the guidance rail 1 along the guidance route of the car M to be parked above the parking floor F. A power supply rail 5 and a signal (communication) rail 5A (power supply / signal rail) installed on the motor vehicle 3 are provided. The electric traveling mechanism 3A of the self-propelled carriage 3, the power supply rail 5 and the signal rail 5A are provided. A mechanical connector 4 that is electrically connected in a separable manner is provided so that it can be separately mounted on the unmanned induction machine 2 and the self-propelled carriage 3, and travel control and power supply are provided via the power supply rail 5 and the signal rail 5A. The self-propelled carriage 3 moves according to the guidance of the unmanned induction machine 2 while receiving the signal.

  Next, the configuration of each part of the guidance system will be specifically described with reference to the drawings. 4 is a front view showing the installation state of the rails 1, 5, 5A and the unmanned induction machine 2, FIG. 5 is a cross-sectional view showing the installation state of the rails 1, 5, 5A and the unmanned induction machine 2, and FIG. It is a perspective view which shows the construction state of rail 1,5,5A.

  As shown in FIG. 5 and FIG. 6, the two guide rails 1 are attached to and installed on the edge of the lower end side of the lower surface open type suspension duct 7 also serving as a rail cover suspended from above. . The power supply rails 5 and the signal rails 5 </ b> A are each fixed in parallel to the support base 8, and the support base 8 is attached to the inner top surface of the suspension duct 7. In FIG. 4, the front side of the suspension duct 7 is seen through, and in FIGS. 5 and 6, the number of the power supply rails 5 and the signal rails 5 </ b> A is shown for a total of five for convenience. However, the power supply rails 5 and the signal rails 5A are installed in a number corresponding to the power supply status and control contents.

  As shown in FIG. 5, the unmanned induction machine 2 has an electric motor 2A that rotates while receiving power supply from two of the power supply rails 5, and the rotation of the electric motor 2A is performed via a gear 2b (on the right side of the figure). (2) When the electric motor 2A rotates according to the direction instructed through the signal rail 5A, the wheel 2a rotates and the unmanned induction machine 2 moves in the instructed direction. .

  As shown in FIG. 1 and the like, the mechanical connector 4 includes an induction machine side connection portion 4A attached to the unmanned induction machine 2 side and a carriage side connection portion 4B attached to the self-propelled carriage 3 side. Thus, as shown in FIG. 7, the unmanned induction machine 2 and the self-propelled carriage 3 are mechanically connected by engaging the induction machine side connection part 4A and the carriage side connection part 4B. Conversely, when the induction machine side connection portion 4A and the carriage side connection portion 4B are disengaged, the unmanned induction machine 2 and the self-propelled carriage 3 are mechanically separated.

  As shown in FIG. 5, the induction machine side connection portion 4A is fixed to the lower surface of the unmanned induction machine 2, and as shown in FIGS. 8 (a) and 8 (b), the two engagement pieces 4A1 can be moved in and out. , 4A2 can be moved in and out of the side surface, and the engagement pieces 4A1 and 4A2 are retracted by the action of a lever driven by an electric actuator, for example, as shown by a one-dot chain line in FIG. It is assumed that the configuration protrudes. In this case, springs S1 and S2 are attached to the central portions of the engagement pieces 4A1 and 4A2, respectively, and compression and extension are operated by the actuators AC1 and AC2, respectively.

  As shown in FIG. 3, the cart-side connecting portion 4B is fixed to a substantially central portion of the outer surface of the frame 3B in which the frame material is assembled in a hut shape, and is shown in FIGS. 9 (a) and 9 (b). As described above, the induction machine side connection portion 4A has the large concave portion 4B1 into which the entire induction machine side connecting portion 4A is fitted, and the engaging concave portions 4B2, 4B3 into which the protruding engaging pieces 4A1, 4A2 are fitted are provided on the inner surface of the large concave portion 4B1. . In this case, the frame 3B is a folding type.

  The mechanical connector 4 has the configuration shown in FIGS. 7, 8, and 9, and mechanical joining involving the induction machine side connection portion 4A and the carriage side connection portion 4B will be described in detail below.

  The engaging piece 4A1 of the induction machine side connecting portion 4A is kept in the state where the compression coil spring S1 storing the force by compression at the center of the piece is stretched, that is, left open and overhanged, and the engaging piece 4A2 is at the center of the piece. The unmanned induction machine 2 is moved toward the self-propelled carriage 3 with the tension coil spring S2 storing a force by a certain tension being compressed, that is, opened and retracted. At that time, the actuators AC1 and AC2 are both free. The induction machine side connection part 4A reduces the speed of the groove part 4B1 of the self-propelled carriage side connection part 4B, and enters the groove part 4B1 in FIG. The right side of the induction machine side connection portion 4A in FIG. 8A passes through the Z point of the groove portion 4B1 in FIG. 9, and also passes through the narrow Y point of the groove portion 4B1. The engagement piece 4A2 also passes through the coil spring S2 without any trouble because of the compressed state.

  Next, although the engagement piece 4A1 is in an overhanging state, it passes through the point Z because of its wide width. In this case, the compression coil spring S1 is in an extended state, and is compressed as the groove portion 4B1 gradually narrows as the induction machine side connection portion 4A advances, and begins to accumulate force. At the same time that the rear corner portion X of the engagement piece 4A1 passes through the point Y of the groove portion 4B1, the compression coil spring S1 is instantaneously released and extended, and the tip of the engagement piece 4A1 is fitted into the small engagement recess 4B2. . This operation stops the conduction of the power circuit with the self-propelled carriage 3 and the unmanned induction machine 2. The signal circuit also supports this.

  4 A of induction machine side connection parts will advance in the groove part 4B1 at low speed, and it will advance, searching for a stop position, and the stop position in the mechanical joining of the unmanned induction machine 2 and the self-propelled carriage 3 is determined, and it is for engagement. The piece 4A1 is fitted into the small engagement recess 4B2 and the power circuit (power supply rail) 5 is conducted.

  After that, the engagement piece 4A2 sends a signal by the power circuit (feeding rail) 5 and the signal circuit (signal rail) 5A that are conducted to the induction machine side connection portion 4A, and operates the actuator AC2 so that both sides are connected. Is extended and fitted into the small engagement recess 4B3. Then, transmission of a control signal and power supply into the cart side connection unit 4B are started.

  Separation of the induction machine side connection portion 4A and the carriage side connection portion 4B is performed in a procedure substantially opposite to the above-described joining. The difference is that the compression coil spring S1 is compressed to prepare that the X point of the engagement piece 4A1 passes through the Y point of the groove 4B1, and the unmanned induction machine 2 is removed from the self-propelled carriage 3 by passing this Y point. Will be separated. After the separation, the actuators AC1 and AC2 are immediately turned off to be free to prepare for the next mechanical joining. In this case, the reason why the actuators AC1 and AC2 are separate pieces and separate circuits is to avoid electromagnetic interference.

  In the case of the present embodiment, the electrical circuit is combined with the mechanical connector 4 so that the entire circuit can be made compact, and the electrical circuit is connected in conjunction with the connection operation of the mechanical connector 4. The unmanned induction machine 2 and the self-propelled carriage 3 are mechanically connected and electrically connected at the same time, and the unmanned induction machine 2 and the self-propelled carriage 3 are mechanically separated. As a result, the electrical connection operation is effectively omitted as a result of the electrical separation.

  The feeding rail 5 and the signal rail 5A are connected to the induction machine side circuit by the current collector 9 that maintains the mechanical contact with the feeding rail 5 and the signal rail 5A even while the unmanned induction machine 2 is moving. It is. Power feeding / communication to the unmanned induction machine 2 itself is also performed via the current collector 9. Further, the electrical connection between the cart side connection portion 4B and the electric traveling mechanism 3A is also made by an electric circuit. Further, control signals necessary for operation of the unmanned induction machine 2 and the self-propelled carriage 3 are sent via a signal rail 5A from a controller or a centralized controller carried by the administrator.

  Next, a vehicle warehousing operation by the guidance system of this embodiment will be described. As shown in FIG. 10, the car M to be parked that has arrived at the doorway P is placed on the self-propelled carriage 3, and the unmanned induction machine 2 and the self-propelled carriage 3 are connected by mechanical connectors 4A and 4B. Connected mechanically and electrically. As the unmanned guide machine 2 travels along the guide rail 1 to the storage position Q of the automobile M along the route indicated by the one-dot chain line arrow A in FIG. 2, the trackless self-propelled carriage 3 is moved to the automobile M. In accordance with the guidance of the unmanned induction machine 2, the vehicle advances along the guidance route toward the storage position Q in the form guided by the unmanned guidance machine 2.

  Then, as shown in FIG. 11, after the self-propelled carriage 2 arrives at the storage position Q of the automobile M, the mechanical / electrical connection by the mechanical connectors 4A and 4B is cut off and the self-propelled carriage 3 is removed. When the unmanned induction machine 2 is disconnected, the car M completes the receipt of the self-propelled carriage 3 together.

  Next, the vehicle unloading operation by the guidance system of the embodiment will be described. As shown in FIG. 12, the unmanned induction machine 2 and the self-propelled carriage 3 are connected at the storage position Q of the car M that is being stored. The self-propelled carriage 3 is guided by the unmanned induction machine 2 along with the guidance of the unmanned induction machine 2 along with the automobile M in conjunction with the unmanned guidance machine 2 moving along the guidance rail 1 toward the entrance P of the parking lot. In this way, proceed along the route indicated by a two-dot chain line arrow B in FIG.

  During unloading, the unmanned guide machine 2 and the self-propelled carriage 3 enter the reversing area U indicated by the two-dot chain line in FIG. 2 and change the direction of movement once, as shown in FIG. The self-propelled carriage 3 arrives at the entrance / exit P of the parking lot with M facing forward to the entrance / exit P of the parking lot. Subsequently, when the automobile M of the self-propelled carriage 3 advances from the entrance P to the outside of the parking lot, the delivery is completed.

  According to the article guidance system of the embodiment having the above-described configuration, the car M to be parked is transported by the self-propelled carriage 3 that runs between the parking lot entrance P and the storage position Q of the car M by itself. Car M can be transported with light equipment. Furthermore, in addition to the self-propelled carriage 3 being a trackless type, the unmanned induction machine 2 for guiding the self-propelled carriage 3 and the guide rail 1, the power supply rail 5, and the signal rail 5A are provided on the parking floor F. Since it is arranged and installed above the machine, and the mechanical connection is also an electrical circuit connection, it is mounted on the self-propelled carriage 3 and the unmanned induction machine 2, so that the floor-free structure is virtually Become. Further, if one unmanned induction machine is provided, a large number of self-propelled carriages can be operated, and high convenience and reduction in manufacturing costs can be realized.

[Another embodiment]
(1) Regarding the vehicle warehousing operation by the guidance system of the present embodiment, as shown in FIG. 2, an example in which a reversal area U is provided on the far rear side of the entrance / exit P has been shown. It is good also as a structure which installs the hangar which has arrange | positioned.

  One storage location exists as an empty section near the entrance of the article storage site. According to this configuration, in addition to this section, a self-propelled carriage is used as a plurality of spare trucks in the hangar near the entrance. While arranging, it can be set as the structure which is made to wait for warehousing at the entrance and exit of an article | item mounting place, and also arrange | positions to all of each storage position. As the storage operation of the article storage site progresses, complex and random entry / exit instructions will be issued, but the storage position is a mixture of the state during article storage and the storage state of empty carts, the order of entry / exit instructions, Depending on the position or the like, unattended induction machine invitations sometimes require complicated and detour movements for guiding, storing, and pulling out a cart loaded with articles, and for storing and pulling out an empty cart. However, according to this configuration, by providing a hangar in which a spare empty cart is arranged near the entrance / exit P, it is possible to avoid such unreasonable and inefficient movement and efficiently move the cart. .

  Inside the hangar, the self-propelled cart 3 is bulky because the frame 3B is extended, but the cart at the bottom of the shelf is folded as shown in FIG. 14 (only two steps are shown to avoid complication). It is. When there is an exit instruction, the frame 3B extends only in the uppermost carriage in response to the instruction, and the apparatus stands by in a state where it can be immediately connected to the induction machine side connection unit 4A. The self-propelled carriage 3 is all placed and stored on the rotating roadbed 12. The rotary roadbed 12 is repelled vertically around the axis 11 by a driving machine (not shown) according to the number of storages of the self-propelled carriage 3 or is placed in a horizontal position (a self-propelled carriage is placed). Case). The lower self-propelled carriage 3 is arranged with the frame 3B folded and compressed in bulk.

  According to this configuration, the article storage site can be a multi-story floor structure extending over the ground or the basement, the number of storage can be increased, the movement of the unmanned induction machine 2 is further complicated, and a spare self-propelled carriage is installed. Even if the number is increased, the articles can be transported and stored quickly and efficiently by moving up and down the storage shelves inside the self-propelled cart hangar.

(2) Provide a turntable for rotating the self-propelled carriage on the self-propelled carriage traveling path near the entrance of the article placement place so that the direction of the self-propelled carriage can be changed with the article. It is preferable. In that case, the unmanned induction machine and the self-propelled carriage are connected by a connector, but only the self-propelled carriage (the article placed thereon) is directed via the rotating member 10C (without the drive mechanism). Can be converted. If it does in this way, it can take out in the direction opposite to the direction at the time of receipt of the goods laid in the self-propelled cart. In this case, the direction of the induction machine side connection part 4A and the cart side connection part 4B does not change by such a direction change.

(3) The connector of the induction machine side connection part and the cart side connection part can be horizontally rotated by remote control by a signal. In this way, it is possible to separate the unmanned induction machine from the self-propelled carriage by changing the direction of the connection between the induction machine side connection part and the carriage side connection part, not the direction change of the self-propelled carriage by the turntable. Connection can be ensured.

  In some cases, the unmanned induction machine travels only in a reciprocating motion along the guide rail, and because of the structure of the connector, it is necessary to change the direction. For example, (i) when the unmanned guidance machine guides the self-propelled carriage and completes storage at the storage position, (ii) after that, when the unmanned guidance machine pulls the self-propelled carriage to the opposite article storage position, (iii) When an unmanned induction machine guides a self-propelled carriage and returns to the entrance of the article storage site.

  In the case of (i), the connection state between the induction machine side connection portion and the carriage side connection portion may be unable to leave because the carriage side connection portion has a bag shape. In that case, a signal is sent to both by remote operation to change the direction of the connection between the two. That is, the configuration of the mechanical connector 4 in this case is such that an induction machine side connection part substrate 4A0 is interposed between the induction machine side connection part 4A and the unmanned induction machine 2, as shown in FIG. The connecting portion 4A and the induction machine side connecting portion substrate 4A0 are connected to each other via a rotating member 10A having a drive mechanism that can rotate around the rotation axis, and the carriage side connecting portion 4B is connected to the upper portion of the frame 3B. A carriage side connection board 4B0 is interposed between the carriage side connection section 4B and the carriage side connection section 4B. And it connects with the boundary part of the trolley | bogie side connection part 4B and the trolley | bogie side connection part board | substrate 4B0 via the rotating member 10B which has a drive mechanism. When these are instructed / transmitted to rotate the rotating members 10A and 10B by remote control, the induction machine side connecting portion 4A and the cart side connecting portion 4B are integrally turned.

  In the case of (ii), a direction change instruction is transmitted by remote control only to the rotating member 10A at the boundary between the induction machine side connection part 4A and the induction machine side connection part board 4A0, and only the induction machine side connection part 4A is transmitted. The direction is changed (if the induction machine side connection portion 4A does not change direction, the connection mechanism does not match the bogie side connection portion 4B and connection cannot be made).

  The case (iii) is the same as the case (i). In either case, useless movement of the unmanned induction machine can be prevented and efficient conveyance can be achieved.

(4) In the case of the guidance system of the above embodiment, the configuration in which the control is performed by the wired system using the signal rail 5A is shown, but a wireless communication device is mounted on an unmanned induction machine or a self-propelled carriage instead of the signal rail 5A. Thus, the configuration may be such that control is performed in a wireless manner.

(5) In the case of the guidance system of the above embodiment, the entrance / exit is a shared parking lot. However, the guidance system of the present invention can also be applied to a parking lot with separate entrance and exit.

(6) In the case of the guidance system of the above embodiment, an example of a trackless was described, but instead of this, a simple rail was previously laid on the floor, and a self-propelled carriage was installed along this rail. You may make it drive | work.

(7) In the above-described embodiment, the automobile is used as the article to be transported and the parking lot is used as the article placement site. However, the present invention is not limited to these. For example, not only an article container such as a container but also an article to be conveyed itself may be an object to be conveyed, and an article placement place may be a container yard, a general warehouse, a factory material place, or the like.
