DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving apparatus used for moving a group of moving bodies on a fixed path on a floor side, for example.
The present invention relates to a body-using transport facility .

[0002]

2. Description of the Related Art Hitherto, for example, Japanese Patent Application Laid-Open No. 2-209309 discloses a configuration for moving a non-driving moving body on a fixed path. This conventional configuration,
A movable body transport device is provided above the fixed path on which the movable body can travel, and a brake device is provided below. The movable body transport device includes a pair of left and right feed rollers that can freely contact the side surface of the movable body, and a rotation driving device that is interlocked with these feed rollers. In addition, the brake device, a pair of left and right brake rollers that can freely contact the side surface of the movable body,
And a torque motor for applying a reverse feed rotational force to these brake rollers.

According to such a conventional structure, a large driving force is applied to the movable body by forcibly rotating both feed rollers abutting on both side surfaces of the movable body by the rotary driving device. The movable body can move on a fixed path.
At that time, the movable body pushes and moves the movable body group that has stopped before.

[0004] In the lower part of the fixed path, the reversely rotating brake roller is in contact with both side surfaces of the movable body, so that a propulsive force acts in the reverse transport direction on the movable body, and the feed roller rotates here. Since the force is greater than the reverse rotation torque, the brake roller is rotated to the feed rotation side in accordance with the difference. As a result, the lower movable body is moved under the braking action, and accordingly, the movable body group is moved in a densely pushed state without creating a gap between the front and rear ends.

[0005]

According to the above-mentioned conventional structure, the non-driving movable body is manually inserted into the starting end of the fixed path, and the inserting operation cannot be easily performed. In addition, since the movable body is a trolley-type movable body that is made rigid (integrated), for example, in the case of a movable body that handles a long transported object, the entire body becomes larger and heavier.

Further, when the feed device is applied to the movable body, it can be performed without any trouble when the fixed path is straight. However, the fixed path is curved in plan view (turn path section, etc.) or in side view. In a curved path section that moves from the horizontal path section to the ascending path, or in a curved path section that moves from the horizontal path section to the lower ascending path, the relative angle formed by the front and rear movable bodies becomes an acute angle so that the push cannot be smoothly performed, In particular, the longer the movable body is, the sharper the relative angle becomes. Therefore, it cannot be adopted for a fixed path having such a curved path portion.

[0007] As shown in Japanese Patent Application Laid-Open No. 61-166768, for example, there is also provided a configuration in which a plurality of carriers (movable bodies) are connected and pushed and moved. However, since the push is performed by abutting between the cushioning members provided at the side edges of the wide carrier, the carrier is inclined by the displaced push force, so that stable movement cannot be performed on a curved path.

The chain 74 is provided with a plurality of projecting transmission portions 75 and the like which are provided on the 74 and can be engaged with the passive portion 29 from the upper side, and the chain 74 is driven along a part or the entire length of both the path portions 5c and 5d. It is arranged to be.

Next, in the first embodiment, the moving body 10
Will be described. For example, feed-in / feed-out device
The moving body 10 sent out by operating 65 in the same manner as a first feeding device 40 described later is moved in a state where the first feeding device 40 side is ready to receive. At that time, the tail of the group of mobile units 10 located in a dense train on the fixed route 5
The contact surface 39 of the rear end portion of the moving body 10 in contact with contact surface 38 of the front end of the fed the moving body 10 abuts, to move the moving body 10 group in feeding force of the feeding device 65 feeds Te than .

The feeding by the feeding / sending device 65 is stopped when the front end of the moving body 10 enters the first feeding device 40. At this time, the cylinder device 51 in the first feeder 40 is extended, and the support member 44 is swung outward around the longitudinal axis 45, so that the feed roller 49 is moved to the passive surface as shown by the phantom line in FIG. Separated from 15. Therefore move
The moving body 10 is moved (loaded) without any trouble.

Thereafter, the feed roller 49 is moved closer by the reverse action to the above, and is brought into pressure contact with one of the passive surfaces 15 as shown by the solid line in FIG. Thus, the front frame body 12 is sandwiched between the rollers 49 and 54. At this time, the feed roller 49 is rotationally driven by the rotary driving device 46. Therefore, by pressing the forcibly rotating feed roller 49 against the passive surface 15, a moving force is given to the moving body 10 by the feed rotating force A, so that the moving body 10 has a desired movement on the fixed path 5. The moving body 10 is moved at a speed, and pushes and moves the group of moving bodies 10 located in a dense train shape on the fixed route 5.

At the time of such movement, each guided device 30, 3
The guides 1 and 32 are supported and guided by the rail 3 via the supported rollers 36, and each of the guided rollers 37 abuts on the guide member 4, which is distributed up and down, to provide a guide without play.
The moving body 10 is prevented from falling down.

The feed amount of the moving body 10 by the first feeder 40 is detected by an encoder or the like, and when a predetermined certain feed amount is detected, the feed roller 49 is separated and the moving operation is stopped. The moving body 10 moving on the fixed path 5 is braked by the braking device 60. That is, when the moving operation of the moving body 10 by the first feeding device 40 is stopped, the cylinder device in the braking device 60 is contracted, and thus the braking roller 61 is separated. Then, in conjunction with the feed movement of the first feed device 40, the braking roller 61 is moved closer to the passive surface 15 by an action reverse to that described above, and at this time, the braking roller 61 is It is rotationally driven to the opposite side.

That is, the braking roller 61 is forcibly rotated in the reverse direction by the drive of the reverse rotation driving device 62. Therefore, when the forcibly rotating braking roller 61 is pressed against the passive surface 15, a propulsive force in the reverse movement direction acts on the moving body 10 due to the reverse rotation torque B, and here, the rotation torque A is reversed. Since the rotation force is larger than B, the braking roller 61 is rotated to the feed rotation side in accordance with the difference, and the load at that time is absorbed by the torque motor.

With this, the transfer corresponding to the poor braking device 60 is performed.
The moving body 10 is moved under the braking action, and therefore, between the first feed device 40 and the braking device 60, the plurality of moving bodies 10 create a gap between the front and rear ends thereof. It will be lined up in a tightly pushed state without any. The braking action of the braking device 60 is stopped immediately before and after the first feed device 40 stops moving.

As described above, while the moving body 10 is intermittently moving on the fixed path 5 or while the moving body 10 is stopped, various operations can be performed on the transferred object W by the operator. The moving body 10 pushed out of the braking device 60 by the above-described push reaches the feed-in / feed-out device 65.

The movement of the moving body 10 by the first feeder 40 is performed by moving the feed roller 49 from the passive surface 15 of the front frame 12 to the passive surface 15 of the intermediate frame 13 and the rear frame 14. This is performed by sequentially acting on the passive surface 15.

At this time, the feed roller 49 is connected to the front frame body.
When acting on 12, the intermediate frame body 13 and the rear frame body 14 are pulled and moved through the coupling device 20, and when acting on the intermediate frame body 13, the front frame body 12 is The rear frame body 14 is pulled and moved via the coupling device 20 while being pushed through the

The contact position 38 comes into contact with the contact portion 39 from right behind because of the posture, and the pushing movement can be performed smoothly and reliably thereafter.

In the curve path section 5b, each frame body
12, 13, and 14 will be pushed and moved in a bent position along the curve at the coupling device 20 in plan view. Thereby, in a plan view, the relative angle Θ formed by the rear frame body 14 of the preceding moving body 10 and the front frame body 12 of the succeeding moving body 10 becomes an obtuse angle, and the abutting portion 38
Are brought into contact at an obtuse angle, and thereafter the pushing movement can be performed smoothly and reliably. The bending is performed by relative rotation around the vertical pin 23 in the coupling device 20.

c to the second feeder 70
Can move on the branch route section 5c. Second feeder
The moving body 10 that has been moved along the merging path 5d by 70 is
By the moving force, it can join the straight path portion 5a, and thereafter, is subjected to the action of the feeding and feeding device 65.

The movement of the moving body 10 by the second feeding device 70 is performed by rotating the chain 74 by the driving device 73 or the like.
This is performed by engaging the transmission unit 75 with the passive unit 29 of the moving body 10 from the superior side and applying a running force to the moving body 10. Then, when the transmission unit 29 is disengaged from the passive unit 29, the application of the traveling force to the moving body 10 is released. At that time, the running force may be partially applied, and the rest may be pushed and pushed as described above.
