  Further, according to a twelfth aspect of the present invention, an openable / closable stopper (stopper 65) is provided at the end of the movable rail 6 on the transfer traveling body delivery side to stop the movement of the transfer traveling body 1 toward the auxiliary rail 58. The stopper 65 and the auxiliary rail 58 are provided, and when the auxiliary rail 58 is in the standing open posture, the stopper 65 is in an action posture to stop the transporting traveling body 1 and the auxiliary rail 58 is in a use posture. In some cases, the stoppers 65 can be interlocked with each other so as to be in a non-acting posture that allows the transport traveling body 1 to travel toward the auxiliary rail 58.

In addition to switching, when the auxiliary rail 58 switches from the use posture to the standing open posture, the stopper 69 can be switched from the non-operation posture to the operation posture.

  In the delivery facility for the transport traveling body according to the present invention having the above-described configuration, when the transport traveling body is transferred from the main rail side where the movable rail is in the connected state to the movable rail side, the friction drive wheel is in the drive release position. Is moved to the driving position and then switched to the driving position, and the friction driving wheel is brought into contact with the friction driving surface of the conveying traveling body stopped at a predetermined position on the main rail side. Is rotated in the direction of retracting the transport traveling body, the transport traveling body is propelled from the main rail side to the movable rail side, and at the same time, the friction drive wheel is moved to the retracted position, thereby moving the entire transport traveling body. Can be transferred to the rail side. On the other hand, when the transfer traveling body is transferred from the movable rail side to the main rail side where the movable rail is in the connected state, the friction drive wheel in the retracted position is switched to the drive position and the transfer traveling body is moved. It is in contact with the friction drive surface and is driven to rotate in the feed direction of the transport traveling body, and the transport travel body is propelled from the movable rail side to the main rail side, and at the same time, the friction drive wheel is moved to the advanced position, thereby transporting. The entire traveling body can be transferred to the main rail side.

  In other words, according to the delivery facility for a transport traveling body of the present invention, the friction drive wheels need only be provided on the movable rail side, and the main rail to which the movable rail can be connected by movement or rotation stores the transport traveling body. Even if there are a lot of storage equipment arranged side by side along the moving path of the movable rail, the transfer traveling body is transferred between the movable rail and each storage rail (main rail). Therefore, it is possible to carry out at a low cost while minimizing the cost for the means and control. Of course, the friction drive wheel is switched to the drive position where it is in pressure contact with the friction drive surface of the transport traveling body only when the transport traveling body is actually driven to the movable rail side and driven to the main rail. When the other friction drive wheels are moved to the advance position as the drive start position, or when the friction drive wheels are returned to the retracted position after the delivery drive of the transport travel body is completed, the friction drive surface of the transport travel body Since it is switched to the drive release position that is separated from the drive force, it is possible to increase the pressure contact force of the friction drive wheel against the friction drive surface without using a means for locking the position of the transport traveling body until the start of driving or to ensure strong force. Even if it is possible to drive smoothly, the traveling body for conveyance does not move in an undesired direction following the movement of the friction drive wheel, and the expected action is reliably performed. Door than it can.

  When carrying out the present invention, according to the configuration of the second aspect, the stroke of the reciprocating movement of the friction drive wheel can be achieved even in a facility that handles a long-sized transport traveling body that transports a long object. The friction drive wheel moving means can be made small and inexpensive at a short time. According to the third aspect of the present invention, the transfer traveling body can be transferred between the movable rail and the main rail to which both ends thereof are connected by one friction drive wheel. Further, by adopting the configuration according to claim 4 or claim 5, the delivery facility of the present invention can be implemented easily and inexpensively.

  Furthermore, according to the structure of Claim 6, the attitude | position of the conveyance traveling body friction-driven with a friction drive wheel can be maintained in the attitude | position parallel to a running direction, a movable rail and the main rail in which this is a connection state Therefore, the transfer driving body can be transferred and propelled by the friction drive wheels between the motor and the vehicle.

  According to the seventh aspect of the present invention, the transport traveling body is frictionally driven while reliably generating a necessary friction force between the friction drive surface of the transport travel body and the friction drive wheel. Since it is possible to prevent the wheels from being tilted by the pressure contact, even if it is a type of transportation traveling body that is suspended from a guide rail via a trolley, the transportation traveling body can be reliably driven to drive. In this case, according to the structure of Claim 8, the effect | action of the said backup roller can be made more reliable. Moreover, according to the structure of Claim 9, the structure using a backup roller can be implemented easily easily.

  Furthermore, according to the configuration of the tenth aspect, when the movable rail is moved, the movable rail and the main rail are moved so that the movable rail and the main rail do not come into contact with each other even if there is some shaking. The presence of an auxiliary rail that fills the gap between the rails makes it possible to make the gap between the rail and the transfer rail between the movable rail and the main rail in a connected state safe. It can be done reliably. In this case, according to the structure described in claim 11, the position shift in the lateral direction between the movable rail and the main rail in the connected state is prevented by using the switching of the posture of the auxiliary rail. Thus, the transfer traveling body can be transferred between the rails more securely and reliably.

  Further, according to the structure of the twelfth or thirteenth aspect of the present invention, an accident in which the transport traveling body supported by the movable rail is idled during the movement of the movable rail and falls off the movable rail, In the situation where the movable rail is not connected to the rail, the stopper can prevent the accident that the transport traveling body supported by the main rail is idle and falls off from the main rail. Even if the opening / closing operation of the stopper is not manually performed, it can be automatically performed by using the posture switching of the auxiliary rail.

That is, the drive lever 50 is rotated forward by a required angle by the motor 49 with a speed reducer of the friction drive wheel position switching means 25, and the drive member 41 is moved closer to the movable rail 6 via the vertical shaft roller 51 and the cam hole 52. Friction drive wheel support member 40 through transmission member 41a, spring receiving seat plate 42d of connecting tool 42, spring 43, spring receiving seat plate 42e of connecting tool 42, connecting tool 42, and vertical support shaft 42b. Is pivoted horizontally around the vertical support shaft 39 inwardly approaching the movable rail 6, and the friction drive wheel 24 supported by the friction drive wheel support member 40 is moved to the friction drive surface of the transport traveling body 1. The drive position is switched to 4 a (one side of the load bar 4) by the compression reaction force of the spring 43. At this time, the load bar 4 of the transporting traveling body 1 is received by the pair of front and rear vertical axis rollers 56a and 56b of the backup means 23A, and the friction drive wheel 24 moves the friction drive surface 4a between the vertical axis rollers 56a and 56b. Since the pressure is applied, the necessary frictional force can be reliably generated between the friction drive wheel 24 and the friction drive surface 4a.

  Next, the friction drive wheel 24 is rotationally driven by the motor 45 with a speed reducer in the pulling direction of the transport traveling body 1, whereby the friction force between the friction drive wheel 24 and the friction drive surface 4 a of the transport traveling body 1 is obtained. Thus, the transporting traveling body 1 that is stopped and waiting at the predetermined end position of the warehousing main rail 19 is drawn to the movable rail 6 side that is connected to the terminal end of the warehousing main rail 19, and each trolley 5 is The transfer traveling body 1 is transferred to the movable rail 6 while transferring from the rail 19 to the movable rail 6. Simultaneously with the pulling-in operation of the conveyance traveling body 1 by the friction drive wheel 24, the pinion gear 34 is rotationally driven in the reverse direction via the transmission gear 35 by the motor 36 with a reduction gear of the friction drive wheel moving means 26, and via the rack gear 33. The movable body 27 is moved backward in parallel with the movable rail 6 via the upward groove-shaped rails 29a to 29c on the upper side on the movable body 27 side and the rollers 32a to 32c on the fixed substrate 31 side. 27, the friction drive wheel 24 supported by the front and rear guide rollers 37a and 37b is moved from the advanced position F to the retracted position R (see the solid line in FIG. 4A). Even in this state, the pair of front and rear vertical shaft rollers 53a and 53b of the backup unit 22A work in the same manner as the pair of front and rear vertical shaft rollers 56a and 56b of the backup unit 23A on the friction drive wheel 24, and the transport traveling body 1 Enables reliable pull-in drive.

  As a result of the above action, the friction drive wheel 24 in the state of returning to the retreat position R can pull the entire transport traveling body 1 from the main rail 19 for transfer to the movable rail 6 side and transfer it. In a state where the entire body 1 is transferred to the movable rail 6, the driving of the friction drive wheel 24 by the motor 45 with a speed reducer is stopped, so that the traveling body 1 for conveyance from the main rail 19 to the movable rail 6 side is stopped. Pull-in transfer is completed. Note that the load bar 4 of the transport traveling body 1 that is transferred and transferred to the movable rail 6 side in this way is the friction drive wheel 24 of the transport traveling body transfer device 21B on the opposite side at the end of the transfer process. Therefore, the friction drive wheel 24 of the transfer traveling body transfer device 21B is switched to the drive release position by the friction drive wheel position switching means 25, and the transfer travel body 1 entering the vehicle is entered. It is desirable to prevent the friction drive wheel 24 of the traveling body transfer device 21B from coming into contact with the load bar 4 (friction drive surface 4a) and causing resistance.

  When the transporting traveling body 1 to be stored is pulled in and transferred to the movable rail 6 side as described above, the traveling driving means 10 of the movable rail hanging moving body 7 is operated, that is, a motor with a speed reducer. 13, the pinion gear 12 is rotationally driven, and the movable rail suspended moving body 7 is laterally moved along the guide rails 8a and 8b to the area adjacent to the storage areas 18A and 18B via the rack gear 11 fixed to the floor side. The movable rail suspension moving body 7 is stopped at a position where the movable rail 6 is connected to the empty storage rail 18a or 18b to store the transporting traveling body 1, that is, the storage rail 18a or 18b to be stored. .

  Next, the transport traveling body delivery device 21A or 21B on the side adjacent to the storage rail 18a or 18b to be warehousing work is operated, and the transport traveling body 1 supported by the movable rail 6 is used for storage in the storage area 18A. The rail 18a or the storage rail 18b in the storage area 18B is sent out. For example, when the transport traveling body 1 is sent out to the storage rail 18a in the storage area 18A, the transport traveling body transfer device 21A is operated, and the transport traveling body 1 is sent from the movable rail 6 to the storage rail 18a and transferred. . That is, the friction drive wheel 24 of the transport traveling body delivery device 21A is switched to the driving position by the pulling and transferring action of the transport traveling body 1 from the immediately preceding main rail 19 for warehousing, and is driven thereafter. When it is not returned to the release position, it is left as it is, or when it is returned to the drive release position, the friction drive wheel position switching means 25 switches the friction drive wheel 24 to the drive position as described above, In a state where the friction drive wheel 24 is in pressure contact with the friction drive surface 4a of the transport traveling body 1, the friction drive wheel 24 is rotationally driven in the delivery direction of the transport traveling body 1 by the motor 45 with a speed reducer. Due to the frictional force between the friction drive wheel 24 and the friction drive surface 4 a of the transport traveling body 1, the transport traveling body 1 that is entirely supported by the movable rail 6 is brought into contact with the movable rail 6. At the same time, the movable body 27 is driven by the friction drive wheel moving means 26 as described above, and the friction drive wheel 24 is integrated with the pair of front and rear guide rollers 37a and 37b. Next, it moves from the retreat position R to the advance position F (see the phantom line in FIG. 4A). In addition, the friction drive wheel 24 of the transport traveling body transfer device 21B on the opposite side is held at the drive release position.

  If the friction drive wheel 24 located at the advance position F adjacent to the end of the storage rail 18a to be warehousing works sends the entire transport traveling body 1 from the movable rail 6 to the storage rail 18a, the friction drive is performed. The drive of the wheel 24 is stopped, the friction drive wheel position switching means 25 switches the friction drive wheel 24 to the drive release position as described above, and the friction drive wheel 24 is friction driven as described above. By moving backward from the advance position F to the reverse position R by the wheel moving means 26, the transfer and transfer of the transport traveling body 1 from the movable rail 6 to the storage rail 18a to be warehousing work is completed.

  When the storage rail targeted for warehousing operation is in the storage area 18B on the opposite side, the friction drive wheel 24 and the friction drive wheel of the transport traveling body transfer device 21B on the side adjacent to the storage rail 18b targeted for warehousing operation. Using the position switching means 25 and the friction drive wheel moving means 26, the conveying traveling body 1 supported by the movable rail 6 as described above may be sent to the storage rail 18b side of the warehousing operation target.

  When the transport traveling body 1 supported by the storage rails 18a and 18b in the storage areas 18A and 18B is transported to the unloading main rail 20, the storage rail on which the transport traveling body 1 to be unloaded is supported. 18a or 18b, that is, the movable rail suspension moving body 7 is caused to travel so that the movable rail 6 is connected to the storage rail 18a or 18b to be delivered, and then the storage rail 18a or 18b to be delivered. What is necessary is just to operate the traveling body transfer device 21A or 21B on the side adjacent to the same as at the time of pulling and transferring the traveling body 1 from the main rail 19 for storage to the movable rail 6 described above. When the transport traveling body 1 to be unloaded has been drawn into the movable rail 6 and transferred, the movable rail suspended moving body 7 is traveled to a position where the movable rail 6 is connected to the unloading main rail 20. Thereafter, the transfer traveling body delivery device 21B on the side adjacent to the unloading main rail 20 is transferred from the movable rail 6 described above to the storage rails 18a and 18b to be moved into the storage rails 18a and 18b. It may be operated in the same way as when it is loaded.

  When carrying out the present invention, for example, in order to enable the movable rail suspension moving body 7 to travel at a high speed, the end of the movable rail 6 and the main rail to which it is connected (in the above embodiment, the storage rails 18a, 18b, When it is necessary to increase the gap between the end of the main rail 19 for entry, the main rail 20 for exit, etc.), when the movable rail 6 is connected to the main rail, Auxiliary rails can be used together. Further, the end of the movable rail 6 on the side of delivering the traveling body 1 for conveyance (both ends in the above embodiment, but may be one end) and the main rail to which the movable rail 6 is connected are conveyed. An opening / closing stopper means for preventing the transport traveling body 1 from floating and falling off from the rail end can also be provided at the traveling body delivery side end. Furthermore, a movable rail positioning means for positioning when the movable rail 6 is connected to the main rail is provided, and the movable rail 6 and the main rail to which the movable rail 6 is connected during the transfer operation of the transport traveling body 1 are provided.

The horizontal support shaft 59 is supported by a pair of left and right bearings 63a and 63b fixed to the upper side of the movable rail 6 through an L-shaped mounting plate 62, and is positioned between the two bearings 63a and 63b. It is fixed to a bearing 63c fixed to the upper side of 58. The tip of the auxiliary rail 58 is cut obliquely in the direction in which the upper side protrudes, and the tip of the main rail 57 connected to the auxiliary rail 58 is inclined in the direction in which the lower side protrudes in accordance with the oblique tip of the auxiliary rail 58. It has been cut.

  The stopper means 64 on the movable rail 6 side is constituted by a stopper 65 fixed to the bearing 63c on the auxiliary rail 58 side. The stopper 65 hangs down into the movable rail 6 through the notch 62a provided on the L-shaped mounting plate 62 on the movable rail 6 side when the auxiliary rail 58 is in the standing open posture shown in FIGS. The trolley 5 of the transport traveling body 1 traveling in the movable rail 6 can be received. The movable rail 6, the main rail 57, and the auxiliary rail 58 may have various structures depending on the type of the trolley 5 of the transport traveling body 1. In this embodiment, a pair of left and right opposed groove-shaped rails are used. The stopper 65 moves up and down between a pair of left and right opposed grooved rail members.

  The stopper means 66 on the side of the main rail 57 is pivotally supported at its upper end by a front / rear horizontal support shaft 68 between a pair of bearing members 67a and 67b attached to one side of the main rail 57 so that it can swing left and right. 9 to 11, the horizontal plate tip 69 a is in an action posture in which the horizontal plate tip 69 a enters the movement path of the trolley 5 of the transport traveling body 1 from the lower side of the main rail 57. The vertical plate portion 69b is configured to come into contact with the receiving member 70 installed between the pair of bearing members 67a and 67b. Further, the vertical plate portion 69b is disposed on the traveling path side of the movable rail suspended moving body 7.

A pair of left and right guide plates 74a and 74b whose upper ends are open to the left and right sides, and a fitting member 75 provided on the upper end of the auxiliary rail 58 are configured. The fitting member 75 is attached to the upper end of the auxiliary rail 58 and extends forward. The side plate attached to the upper end of the board 76 has a gate-shaped bearing plate 77, and the inner side of the portal-shaped bearing plate 77. A pair of left and right guide rollers 78a and 78b, which are supported by a longitudinal support shaft and project from the portal bearing plate 77 to the left and right sides, and an auxiliary rail 58 is shown in FIGS. When it is turned down to the use posture connected to the main rail 57, the gate-shaped bearing plate 77 is fitted between the pair of left and right guide plates 74a and 74b on the main rail 57 side. At this time, the pair of left and right guide rollers 78a and 78b are both The auxiliary rail 58 is configured to rotate in contact with the inner side surfaces of the guide plates 74a and 74b so that the auxiliary rail 58 connects the movable rail 6 and the main rail 57 in a straight line. When a pair of left and right guide plates 74a, the tip portion of the substrate 76 of the auxiliary rail 58 side on receiving plate 79 which is attached on the main rail 57 between 74b is configured to be received.

  The auxiliary rail 58 is provided with an L-shaped stopper 69 of the stopper means 66 on the main rail 57 side when the auxiliary rail 58 is switched to the use posture, and the passive member 72 connected to the L-shaped stopper 69. 14 and an L-shaped relay lever 80 provided on one side of the front end of the main rail 57 are provided with operating means 81 for switching to the non-acting posture shown in FIG. The L-shaped relay lever 80 has an intermediate bent portion horizontally disposed in the front-rear direction on a bearing 82 fixed to the outer surface of the lower end of the guide plate 74a on the side where the L-shaped stopper 69 is provided, of the guide plates 74a, 74b. It is supported by a support shaft 83, and at the tip of the upward lever portion, a transmission roller 84 located inside the passive member 72 provided continuously from the L-shaped stopper 69 is supported by the front and rear horizontal support shaft. At the same time, a passive roller 85 is pivotally supported by a front and rear horizontal support shaft at the tip of the lateral lever portion. The operation means 81 is configured by an operation member 86 attached to the auxiliary rail 58 so as to push down the passive roller 85 of the L-shaped relay lever 80 when the auxiliary rail 58 is switched to the use posture. Reference numeral 87 denotes a support member for attaching the operation member 86 to the side surface of the auxiliary rail 58.

  According to the above configuration, when the movable rail 6 and the main rail 57 are not in a connected state, the auxiliary rail 58 is connected to the auxiliary rail 58 via the horizontal support shaft 59 by the motor 61 with a speed reducer of the driving means 60 as shown in FIGS. By switching to the standing and open posture shown in the figure, a sufficient gap is secured between the movable rail 6 and the main rail 57, and the movable rail suspension moving body 7 can perform high-speed traveling with some rolling without any trouble. be able to. Further, since the auxiliary rail 58 is switched to the standing open posture, the stopper 65 of the movable rail side stopper means 64 is automatically switched to the working posture that enters the inside of the end of the movable rail 6. Even in a situation where the transporting traveling body 1 drawn and transferred to the rail 6 side is present, the transporting traveling body 1 is transported from above the movable rail 6 by being received by the stopper 65 in the action posture. An accident in which the traveling body 1 falls off can be prevented. On the other hand, in the stopper means 66 on the main rail 57 side, the L-shaped stopper 69 is held in an acting posture by gravity, and there is a transport traveling body 1 stored on the main rail 57 side, for example. However, the trolley 5 (specifically, the vertical axis roller for stopping the frame that moves between the pair of left and right groove-shaped rail members) of the traveling body 1 for transportation is located at the front end 69a of the horizontal plate portion of the L-shaped stopper 65 in the working posture. By being received, it is possible to prevent an accident in which the transport traveling body 1 falls off from the main rail 57.

  If the movable rail 6 is stopped at the position where the movable rail 6 is connected to the target main rail 57 by the traveling of the movable movable body 7, the auxiliary rail 58 is driven via the horizontal support shaft 59 by the motor 61 with a speed reducer of the driving means 60. Is switched to the use posture shown in FIGS. At this time, the stopper 65 of the movable rail side stopper means 64 is automatically switched to the non-acting posture in which the stopper 65 of the movable rail-side stopper means 64 is detached upward from the movable rail 6 and is integrated with the auxiliary rail 58 at the same time. The operating member 86 of the operating means 81 that rotates downward pushes down the passive roller 85 of the L-shaped relay lever 80 on the main rail 57 side as shown in FIG. 14, so that the L-shaped relay lever 80 rotates, The transmission roller 84 rotates the L-shaped stopper 69 of the main rail-side stopper means 69 laterally and outwardly against the gravity via the passive member 72 and the support plate 71, so that the L-shaped stopper 69 is brought into a non-acting posture. Switch. Furthermore, when the auxiliary rail 58 is turned to the horizontal posture and switched to the use posture, the fitting member 75 on the auxiliary rail 58 side of the movable rail positioning means 73 is between the pair of left and right guide plates 74a and 74b on the main rail 57 side. So that the movable rail 6 is prevented from moving laterally and laterally together with the auxiliary rail 58 with respect to the main rail 57.

  That is, the gap between the movable rail 6 and the main rail 57 is filled with the auxiliary rail 58, and the stopper 65 of the movable rail side stopper means 64 and the L-shaped stopper 69 of the main rail side stopper main 66 are automatically turned off. Further, the movable rail 6 is positioned with respect to the main rail 57 by the movable rail positioning means 75 with respect to the left and right lateral directions, so that the transport traveling body 1 between the movable rail 6 and the main rail 57 is moved. The transfer can be performed safely via the auxiliary rail 58.

  In the case where only the one end portion of the movable rail 6 is the transfer traveling body transfer end portion between the main rail and the main rail, the friction drive wheel 24 is naturally disposed only on the transfer rail transfer end portion side of the movable rail 6. However, even when both ends of the movable rail 6 serve as transfer traveling body transfer ends between the main rail and the main rail, one friction drive wheel 24 is supported by the movable rail 6 as shown in FIG. The traveling body 1 for transportation supported by the main rail 57A connected to one end of the movable rail 6 and one retracted position R that contacts the central position of the entire length of the friction drive surface 4a in the traveling body 1 that is transported. Reciprocating movement between the friction drive surface 4a and the first advancing position F1 contacting the position near the movable rail side end, and traveling for conveyance supported by the main rail 57B connected to the other end of the movable rail 6. Friction drive surface in body 1 A friction drive wheel 24 is configured to be movable rail by being configured so as to be able to reciprocate between the second advance position F2 that contacts the position near the movable rail side end of a and the one backward position R. 6 can also be used for transfer of the transport traveling body 1 between the main rails 57A and 57B connected to either side of the both ends.

A movable guide rail 89 having an approximately equal length is used, and the friction drive wheel 24 is provided at a substantially central position in the length direction of the movable guide rail 89. In order to shorten the length of each guide rail, the movable guide rail 89 is movable. Two or more guide rails 89 may be provided. In order to reciprocate the friction drive wheel 24 from the retracted position R to the first advanced position F1, or to move the friction drive wheel 24 from the retracted position R to the second advanced position F2, a fixed guide rail As a driving means for reciprocating the movable guide rail 89 with respect to 88, driving of a running fork known as a load transfer means in various cargo handling machines such as a rack and pinion type, a type using a wire rope or chain, etc. Means can be applied. Of course, friction drive wheel position switching means is also used, but it is not shown in FIG.

  In the previous embodiment, the movable rail 6 that is moved in the horizontal direction by the movable rail suspension moving body 7 has been exemplified. However, in the present invention, the movable rail that transfers the transport traveling body to and from the main rail is moved up and down. Alternatively, it may be a movable rail that can move both horizontally and vertically. Further, it may be a movable rail that rotates in order to reverse the front-rear direction of the transport traveling body 1 in the travel route of the transport traveling body 1 or for switching the travel path. Of course, as the movable rail, a structure suitable for the structure of the main rail to which the movable rail is connected and the structure for supporting the transporting traveling body guided by these rails can be used. Further, as the means for moving the movable rail, the movable rail suspended moving body 7 of the floor traveling type trolley type is illustrated, but it may be of the overhead traveling type crane type.
