Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer facility using movable bodies, which is used for densely moving a group of movable bodies on a fixed path on the floor side.

[0002]

2. Description of the Related Art Conventionally, as a means for moving a non-driving type movable body on a fixed path, there has been provided a structure disclosed in, for example, Japanese Patent Laid-Open No. 2-209309. This conventional configuration is
The movable body transporting device is provided on the upper side of a fixed path on which the movable body can travel freely, and the braking device is provided on the lower side. The movable body transporting device is composed of a pair of left and right feed rollers that can come into contact with the side surface of the movable body, and a rotation drive device that interlocks 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,
It is composed of a torque motor that applies reverse feed rotational force to these brake rollers.

According to such a conventional structure, a large propulsive force is applied to the movable body by forcibly rotating both feed rollers, which are in contact with both side surfaces of the movable body, by the rotation drive device. The movable body can be moved on a fixed path.
At this time, the movable body is moved by pushing the movable body group that is preceding and stopped.

On the lower side of the fixed path, since the brake roller which is rotated in the reverse direction is in contact with both side surfaces of the movable body, a propulsive force in the reverse conveyance direction acts on the movable body, and the feed rotation is performed here. Since the force is larger than the reverse feed rotational force, the brake roller is rotated to the feed rotation side according to the difference. As a result, the lower movable body is moved in a state of being subjected to the braking action, and therefore the movable body group is moved in a dense rearward pushing state without forming a gap between the front and rear ends.

[0005]

According to the above-mentioned conventional structure, the non-driving type movable body is manually inserted into the starting end portion of the fixed path, and the insertion work cannot be performed easily. Further, since it 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 whole body becomes large and heavy.

Further, when the feeding device is acted on the movable body, it can be carried out without trouble when the fixed route is linear, but the fixed route is curved in a plan view (a curved route portion, etc.) and a side view. In the curve route part that moves from the horizontal route part to the ascending route, and in the curve route part that moves from the horizontal route part to the ascending route, the relative angle formed by the front and rear movable bodies becomes an acute angle and the boosting cannot be performed smoothly, In particular, the longer the movable body, the sharper the relative angle. Therefore, it cannot be used for a fixed route having such a curved route portion.

Incidentally, as shown in, for example, Japanese Patent Laid-Open No. 61-166768, there is also provided a structure in which a plurality of carriers (movable bodies) are connected and rearwardly moved, but in this case, in a curved path. Since the pushing is performed by the abutting of the cushioning members provided on the side edges of the wide carrier, the carrier is inclined by the displaced pushing force, so that the stable movement cannot be performed in the curved path.

The object of the present invention is to allow a separate feeding device to act on the movable body to easily branch or join a fixed path, and to make the main body of the movable body elongated and compact. The point is to provide a transfer facility using movable bodies, which enables smooth, reliable and stable movement of the movable body group in a dense manner (train-like manner) even on a fixed route having a curved route portion.

[0009]

In order to achieve the above-mentioned object, the transport facility using a movable body according to the first aspect of the present invention comprises a movable body main body, which is supported and guided by rails and is movable on a fixed path, and a connecting device. It is formed by a plurality of frame bodies that are relatively rotatably connected to each other via the side surfaces of these frame bodies as passive surfaces, and at least one of the frame bodies is provided with an object support portion and a rail. A pair of guided devices that are supported and guided on the other side of the frame, a guided device is provided on the free end side of the remaining frame body, and a passive part is provided on the transported object support part. A first feeding device having a feeding roller that can freely come into contact with the surface and a second feeding device having a transmission portion that can act on the passive portion are provided.

In the transfer facility using movable bodies according to the second aspect of the present invention, the front and rear ends of the main body are formed as abutting portions. Further, in the transfer facility using movable bodies according to the third aspect of the present invention, the engaging portion is formed on one of the front and rear ends of the main body, and the engaged portion is formed on the other end.

In the transfer facility using movable bodies according to the fourth aspect of the present invention, the main body is composed of three frame bodies, and the transported object support portion is provided on the intermediate frame body.

[0012]

According to the structure of the first aspect of the present invention described above, it suffices to provide the passive portion on the transported object supporting portion having a shape adapted to the transported object, and the main body can be formed elongated and compact. Then, after the movable body is positioned so as to face the first feeding device, the feed roller that is forcibly rotating is brought into contact with the passive surface, so that the first feeding device applies a propulsive force to the movable body to move on a fixed path. You can move in. Further, by causing the transmission part of the second feeding device to act on the passive part of the movable body, it is possible to apply a propulsive force to the movable body by the second feeding device to move on a fixed path.

In such a movement of the movable body, the main body of each movable body, that is, each frame body can be moved in a linear posture in a plan view and a side view in the straight path portion of the fixed path, and can also be moved to the left, right, up and down. In the curved path portion, each frame body can move in a bent posture along the curve at the connecting device.

According to the structure of the second aspect of the present invention described above, in the linear path portion, since each frame body has a linear posture in plan view and side view, it is located in the central portion in the width direction of the preceding movable body. The abutting portion of the succeeding movable body comes into contact with the abutting portion from directly behind, so that the pushing movement can be smoothly and reliably performed thereafter. In addition, in the left and right or up and down curved path portions, since each frame body is pushed and moved along the curve in a bent posture, the relative angle between the rear frame body of the preceding movable body and the front frame body of the succeeding movable body is formed. Can be made an obtuse angle, and the abutting portion of the succeeding movable body comes into contact with the abutting portion located at the center portion in the width direction of the preceding movable body at an obtuse angle, and the pushing movement can be smoothly and reliably performed thereafter.

Further, according to the structure of the third aspect of the present invention described above, the first or second feed unit is fed to the preceding movable body in a state where the movable body group is connected in a train shape by engaging the engaged portion with the engaged portion. By operating the device, the subsequent movable body group can be moved by pulling.

According to the configuration of the fourth invention described above,
By supporting the guided object with the intermediate frame body and supporting and guiding the guided devices provided on the front and rear frame bodies, the movable body can always be stably moved.

As shown in FIG. 9, a braking device 60 that applies a braking force to the movable body 10 by acting on the passive surface 15 is provided at another predetermined position of the linear path portion 5a. Further, a feeding device 65 is provided between the feeding device 40 and the braking device 60.
Is provided. The arrangement pattern of each device 40, 60, 65 may be variously changed, and the braking device 60 and the sending-in / out device 65 may be partially or entirely omitted.

The braking device 60 has a structure similar to that of the feeding device 40, and is capable of coming into contact with and separating from one side of the passive surface 15 of the movable body 10 from the side, and a braking roller 61 made of urethane, for example. A reverse rotation drive device (torque motor) 62 that interlocks with the braking roller 61 and applies a reverse feed rotational force B to the braking roller 61, and a receiving roller that allows the other passive surface 15 of the movable body 10 to come into contact with each other. It is composed of 63 etc. The reverse feed rotational force B by the reverse rotation drive device 62 is set to be smaller than the feed rotational force A of the rotation drive device 46. Further, the feed-in / feed-out device 65 has the same structure as the feed device 30.

The branch route portion 5c and the merge route portion 5d are
The straight path portion 5 is provided in front of and behind the infeed device 65.
A second feeding device 70, which is connected to a and is operable on the passive portion 29, is arranged along each of the path portions 5c and 5d.

An example of a pair of front and rear sprockets 72 rotatably supported by the support frame 71, a drive device (motor or the like) 73 interlocking with one of the sprockets 72, and an endless rotating body wound between the sprockets 72. A chain 74 and this chain
A plurality of projections 74 are provided on the passive portion 29 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 accordingly.

Next, in the above-described first embodiment, the movable body 10
The moving work will be described. For example, infeed device
The movable body 10 sent out by operating the 65 in the same manner as the below-described first feeding device 40 is moved in a state where the first feeding device 40 side is in the receiving posture. At that time, the contact surface 39 at the rear end of the rearmost movable body 10 of the movable body 10 group located on the fixed path 5 in the form of a dense train is provided with the front end portion of the fed movable body 10. The contact surface (38) comes into contact with the contact surface (38), thereby moving the movable body group (10) by the feeding force of the feeding / feeding device (65).

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

After that, the feed roller 49 is moved closer to and brought into pressure contact with one of the passive surfaces 15 as shown by the solid line in FIG. As a result, the front frame body 12 is sandwiched by the rollers 49 and 54. At this time, the feed roller 49 is rotationally driven by the rotary drive device 46. Therefore, by forcing the feed roller 49 which is forcibly rotated into contact with the passive surface 15, the moving force is given to the movable body 10 by the feed rotation force A thereof, so that the movable body 10 can move in a desired direction on the fixed path 5. It moves at a speed and pushes the movable body group 10 located in the fixed route 5 in the form of a dense train.

During such movement, each guided device 30, 3
1 and 32 are supported and guided by the rail 3 via the supported rollers 36, and the guided rollers 37 abut on the guide members 4 which are vertically distributed, so that the guides without rattling and the movable body 10 Sideways fall prevention is performed.

The feed amount of the movable body 10 by the above-mentioned first feed device 40 is detected by an encoder or the like, and when a predetermined feed amount is detected, the feed roller 49 is separated and the moving work is stopped. The movable body 10 moving on the fixed path 5 is braked by the braking device 60. That is, when the movement of the movable body 10 by the first feeding device 40 is stopped, the cylinder device in the braking device 60 is contracted, and the braking roller 61 is separated. Then, in conjunction with the feeding movement of the first feeding device 40, the braking roller 61 is moved closer to and brought into pressure contact with the passive surface 15 by the action opposite to that described above. At this time, the braking roller 61 is different from the feeding roller 49. It is driven to rotate on the opposite side.

That is, the braking roller 61 is forcedly rotated in the opposite direction by the driving of the reverse rotation drive device 62. Therefore, when the braking roller 61 that is forcedly rotated is brought into pressure contact with the passive surface 15, the reverse feed rotational force B acts on the movable body 10 in the reverse movement direction. Since it is larger than the rotational force B, the braking roller 61 is rotated toward the feed rotation side according to the difference, and the load at that time is absorbed by the torque motor.

As a result, the movable body 10 corresponding to the lower braking device 60 is moved in a state in which it is subjected to the braking action, so that between the first feeding device 40 and the braking device 60, a plurality of movable bodies are movable. The body 10 will be closely pushed and aligned without creating a gap between its front and rear ends. The braking action by the braking device 60 is stopped before and after the movement stop by the first feeding device 40.

As described above, while the movable body 10 is intermittently moving on the fixed path 5 or while the movable body 10 is stopped, the worker can perform various works on the transported object W. It should be noted that the movable body 10 pushed out from the braking device 60 by the above-described backward pushing reaches the feeding-in / feeding-out device 65.

When the movable body 10 is moved by the first feeding device 40 described above, the feed roller 49 is moved from the passive surface 15 of the front frame body 12 to the passive surface 15 of the intermediate frame body 13 and the rear frame body 14. It is performed by sequentially acting on the passive surface 15.

At this time, the feed roller 49 is 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 connecting device 20, and when acting on the intermediate frame body 13, the front frame body 12 is connecting device.

Since the contact portion 38 comes into contact with the contact portion 39 from directly behind, the pushing movement can be smoothly and reliably performed.

In the curved path portion 5b, each frame body is
12, 13, 14 are pushed and moved in a bent posture along the curve at the connecting device 20 in plan view. Thereby, in a plan view, the relative angle Θ formed by the rear frame body 14 of the preceding movable body 10 and the front frame body 12 of the following movable body 10 becomes an obtuse angle, and the contact portion 38 with respect to the contact portion 38.
Will contact each other at an obtuse angle, and the pushing movement can be performed smoothly and surely thereafter. The bending is performed by relatively rotating around the vertical pin 23 in the coupling device 20.

As described above, the movable body 10 can be moved by the endless route portion (circulation route portion) including the linear route portion 5a and the curved route portion 5b. The movable body 10 of the linear path portion 5a is moved by the feeding / feeding device 65 to the branch path portion 5a.
It can be branched by sending it to c, and then the second feeding device 70
Can move on the branch path portion 5c. The second feeding device
The movable body 10 that has been moved along the merging path portion 5d by 70 is
The moving force allows the linear path portion 5a to join, and then the feed-in / feed-out device 65 acts.

When the movable body 10 is moved by the above-mentioned second feeding device 70, the chain 74 is rotated by the driving device 73 or the like,
This is performed by engaging the power transmission section 75 with the passive section 29 of the movable body 10 from the upper side to give a traveling force to the movable body 10. Then, by disengaging the transmission portion 29 from the passive portion 29, the running force applied to the movable body 10 is released. At that time, the running force may be partly applied, and the rest may be pushed and moved as described above.
