Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention is suitable as a branching device for a transportation path of an article transportation vehicle that holds a suspended monorail from one side and travels by itself.

2. Description of the Related Art Generally, an article carrier truck (hereinafter simply referred to as a truck) that travels on a suspended monorail travels while holding the monorail from one side, and the other side of the monorail extends along a traveling route. A C-shaped yoke as shown in FIG. 6 (b) suspended from a horizontal beam
Y ₁ and Y ₂ are attached, and a large number of the yokes are attached to the lateral beam at appropriate intervals to suspend and support the monorail.

Then, when changing the traveling route of the bogie traveling on the monorail during traveling, a main line connecting monorail connecting the upstream main line monorail and the downstream main line monorail to the changed position, and an upstream main line monorail and downstream branch A movable frame body having a branch connection monorail for connecting the monorails is provided, and the movable frame body moves on the fixed frame to switch the connected monorails.

In the conventional suspension monorail branch connecting device, the lengths of the main line connecting monorail and the branch connecting monorail on the movable frame are longer than the length between the front and rear wheels of the bogie.

This is because when the distance between the connecting ends of the main line monorail on the downstream side and the connecting end of the branch monorail is small, the bending prevention C-type yoke Y ₁ that suspends and supports the connecting end of the main line monorail on the downstream side.
And the suspension portion including the carriage driving device projecting to the side of the carriage that holds the branch monorail from one side and that is traveling, and has a positional relationship facing each other, so that the C-shaped yoke Y ₁ and the suspension portion of the carriage are Since they interfere with each other, it is necessary to widen the distance between the opposite side surfaces. As one of the solutions, it is conceivable to widen the interval between the main line connection monorail and the branch connection monorail on the movable frame. However, if the interval is widened, the rail switching stroke of the movable frame becomes longer and the switching operation is performed. Is not performed quickly, and if the curvature of the branch connection monorail is made small, the curve changes rapidly and it becomes difficult for the bogie to travel on the branch connection monorail.
After all, by increasing the length of the connecting monorail on the movable frame, the curvature of the branch connecting rail is increased and the curve change is alleviated so that the traveling of the trolley is not hindered.

Therefore, the length of the connecting monorail on the movable frame is longer than the length between the front and rear wheels of the truck.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above-mentioned conventional technology, since the connecting rail on the movable frame is longer than the front-rear wheel length of the bogie, the bogie completely rides on the movable frame. Is loaded on the movable frame, and the movable frame is loaded with the total weight of the carriage (having a weight of about several tons), the movable frame sinks and is attached to the side surface of the monorail. Rail (power line that gives driving force to the self-propelled carriage) creates a step at the connection end,
The current collector attached to the truck and slidingly contacting the power supply rail was damaged at the step portion, and the step at the monorail connection portion hindered smooth transfer of the truck and was a source of noise.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention eliminates a deflection-preventing C-type yoke that suspends and supports a connecting end of a downstream main line monorail, and attaches a deflection-preventing C-shaped yoke closest to the deflection-preventing yoke. The cross-sectional shape is a triangle, and the long side of the triangle is extended to the connecting end of the downstream main line monorail to suspend and support the connecting end so as not to sink, and further, the main line on the movable frame and the branch connecting monorail. A vertical floating prevention member is attached to one connection end of the movable frame body, and a lateral alignment stopper member is attached to the other connection end of the movable frame body. The movable frame body has a mechanism for locking the position of the movable frame after the switching connection. The operation cylinder device is attached.

Operation The deflection preventing C-type yoke Y ₁ for preventing the sinking of the connecting end of the downstream main line monorail is removed, and the C-shaped yoke Y ₂ closest to the yoke is shown in FIG. by extending the long sides of the triangle on the downstream main monorail connecting end, avoiding interference with the carriage traveling to ERROR to branched monorail and the nearest C type yoke Y _2,
The length of the connected monorail on the movable frame can be made smaller than the length between the front and rear wheels of the bogie so that the entire weight of the bogie is not loaded on the movable frame, and the bogie is transferred to the downstream main line monorail. It is possible to prevent the downstream main line monorail connection end from sinking, and the upstream main line monorail is connected by the vertical floating prevention member and the side alignment stopper member provided at the end of the connection monorail on the movable frame. The step of the monorail does not occur at the connecting portion with the downstream main line monorail and the branch monorail, and in addition, since the movable frame body that has been switched and moved by the lock device of the cylinder device is locked at the connection position without the step, the carriage and the assembly The electrons can smoothly travel and slide and transfer at the connection point.

Example FIG. 1 shows a monorail 1 for main line connection and a monorail 2 for branch connection.
FIG. 3 is a plan view of a rectangular movable frame 3 to which and are attached,
The figure is a front view of FIG. 1, and the movable frame 3 has four wheels 3a running on the guide rails 4a, 4a of a rectangular fixed frame 4 and a guide roller 3b sandwiching one guide rail. A piston rod 5a of a cylinder 5 having a fixed frame 4 and a base end attached thereto.
A cam roller 5b shown in FIG. 3 is attached to the front end of the.

Then, as shown in FIGS. 3 (a), (b), (c) and (d), the operation sequence of the cam roller 5b is shown in FIG.
The coil spring 6 is stretched between the spring attachment 5c fixed to the movable frame 3 and the spring attachment 3c fixed to the movable frame 3,
An elongated hole 3d in the direction of expansion and contraction of the piston, into which an operating pin 5d protruding from the piston rod 5a is loosely inserted, is formed in 3c, and a locking claw 3e is provided in the front end of the movable frame body 3.

Further, a stopper 4b that abuts the front end of the movable frame 3 is attached to the front end of the fixed frame 4, and a locking rod 4d having a locking pin 4c that locks with the locking claw 3e of the movable frame. A cam that is mounted so that it can be lifted up and down, is held in a horizontal position by a supporting rod 4e, and that both sides of the locking pin 4c of the locking rod 4d contact the cam roller 5b at the tip of the piston rod to lift and lower the locking rod 4d. The plate 4f is formed.

Therefore, when the piston rod 5a is extended from the state shown in FIG. 9A, the movable frame 3 is advanced through the coil spring 6, and the state shown in FIG. While contacting the cam surface of the plate 4f to raise the locking rod 4d to the state shown in FIG. 3C, the front end of the movable frame 3 abuts against the stopper 4b and stops, but the piston rod 5a does not have a coil spring. 6 is extended, the operating pin 5d of the piston rod moves forward in the long hole 3d, only the cam roller 5b moves forward, and the locking rod 4d falls as shown in FIG. The pin 4c engages with the locking claw 3e of the movable frame. Therefore, the movable frame 3 is prevented from moving forward by the stopper 4b and is prevented from moving rearward by the locking pin 4c, so that the forward / backward movement is completely locked. Also, the piston rod 5a
When the operation is reduced, the cam roller 5b first comes into contact with the cam plate 4f to raise the locking rod 4d, and the engagement between the locking claw 3e and the locking pin 4c is released, and the piston operating pin 5d becomes the long hole 3d. The movable frame 3 can be retracted together with the piston rod by retracting inside.

In this way, when the piston rod 5a is extended, the first
As shown in the figure, the branch connection monorail 2 on the movable frame is
The upstream main monorail 7 at the fixed position and the downstream branch monorail 8 are connected to lock the connection position, and when the piston rod 5 is reduced, the movable frame 3
1 moves left in FIG. 1, and the upstream main line monorail 7
The downstream main line monorail 7a and the downstream main line monorail 7a are connected by the main line connection monorail 1 on the movable frame.

In FIG. 2, reference numeral 9 is a power feeding rail attached to the side surface of the monorail.

Further, on the side surfaces of the downstream connecting ends of the main line connecting monorail 1 and the branch connecting monorail 2 on the movable frame, a positioning stopper 1a that comes into contact with a positioning rod 7b mounted on the side surface of the downstream main line monorail 7a and a downstream side branch monorail are provided. A stopper 2a that comes into contact with a positioning rod attached to the side surface of 8 is attached to prevent lateral displacement and a fitting member formed at the connection end surface of the upstream main line monorail 7 at the end surface of each upstream connection end. A fitting lateral groove 1b that slides in from the side is formed in 7'to prevent a connection step in the vertical direction.

That is, as shown in FIGS. 4A and 4B, a connection monorail on the movable frame 3, for example, a main line connection monorail 1
A stopper 1a having a groove is attached to the side surface of the connecting end on one side, and the side surface of the connecting end of the downstream main line monorail 7a is fitted into the groove of the stopper 1a as shown in FIG. Positioning rod 7b is attached to contact.

As shown in FIGS. 5 (a) and 5 (b), a lateral groove 1b is formed on the upper surface of the other end of the main line connecting monorail 1 on the movable frame, and a lateral groove 1b is formed on the upper side of the upstream main line monorail 7. Has a fitting member 7'which slides into the lateral groove 1b.

Furthermore, the connecting end of the downstream main line monorail 7a is conventionally suspended and supported by a C-shaped yoke Y ₁ as shown in FIG. 6 (b) in order to prevent sinking during transfer of the bogie. In this state, when the bogie moves from the branch connection monorail 2 to the downstream branch monorail 8, the running locus of the suspension outer line of the bogie holding the monorail from the side is as shown by the broken line T. As shown in Fig. 6 (b), the suspension portion of the truck interferes with the C-type yoke Y ₁ that suspends and supports the connecting end of the downstream main line monorail 7a, which hinders passage of the truck. The yoke Y ₁ is removed and the shape of the yoke Y ₂ closest to the yoke Y ₁ is triangular as shown in FIG. 6 (a), and the long side 10a thereof extends to the connecting end of the downstream main line monorail. C-shaped yoke 10 with existing shape, downstream main line monorail connection The suspension supporting force of the C-shaped yoke is increased to prevent the bending and sinking of the connection end, facilitate the passage of the bogie to the downstream side branch monorail 8 of the bogie, and move the bogie to the downstream main line monorail 7a. In this case, it is possible to prevent a step at the downstream main line monorail connection end.

Advantageous Effect of the Invention The present invention connects the branch connection monorail on the movable frame body between the upstream and downstream fixed branch monorail ends by the extension operation of the piston rod of one cylinder device provided on the fixed frame, and at the same time, moves the same. Since the movable frame body can be locked to the fixed frame by the frame body locking means, the branch connection mechanism is lightened and the operation is simplified, and the branch connection monorail on the movable frame body is curved when the branch monorail is connected. Because the movable frame can be prevented from rolling laterally due to the centrifugal force when passing through the bogie due to its shape, the bogie can be connected and transferred smoothly and without impact, and the power supply rail attached to one side of the rail can also be transferred. Since the connection is made without steps, the current collector attached to the trolley can pass through the connection site without being damaged.

Further, the conventional anti-deflection C-type yoke for suspending and supporting the connecting end of the downstream main line monorail is eliminated, and the C nearest to the yoke is removed.
Since the cross-sectional shape of the die yoke is a triangle and the long side of the triangle is extended to the connection end, the connection end is suspended and supported by the nearest yoke, the distance between the main line monorail on the downstream side and the branch monorail is reduced. Even if the vehicle is not particularly enlarged, it is possible to avoid a trolley that travels from the branch connection monorail to the downstream branch rail interfering with the C-shaped yoke near the connection end of the downstream main line monorail, and to travel smoothly. Therefore, it is not necessary to increase the distance between the main rail connecting monorail and the branch connecting monorail on the movable frame, and the length of the main rail connecting monorail and the branch connecting monorail on the movable frame is less than the length between the front and rear wheels of the bogie. It became possible to set it short.

Therefore, since either one of the front and rear wheels of the bogie is on one of the upstream main line monorail, the downstream main line monorail, and the downstream branch monorail, the movable frame is not loaded with the entire weight of the bogie and the movable frame Sinking due to the weight of the body is also suppressed, and lateral alignment stopper means attached to the connecting ends of the connecting monorail on the movable frame and the fixed monorails on the upstream and downstream sides and vertical floating prevention By the means, the step of the rail at the rail connecting end is completely prevented, and the practical effect as a branch connecting device for changing the traveling route of the bogie traveling on the suspended monorail is great.
