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, since the movable body is a rigid (integrated) trolley type movable body, for example, in the case of a movable body for handling a long transported object, the whole is Larger and heavier.

When the feeding device acts on the movable body,
A curved route part (a turn route part, etc.) where a certain route is curved in a plan view, a curved route part that moves from a horizontal route part to an ascending route in a side view, and a curved route part that moves from a horizontal route part to a descending route In, 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.

Further, when there is not a required number of movable bodies between the movable body conveying device and the braking device, the movable body on the leading side moves in a runaway manner and various operations cannot be performed. In addition, a movable body that has left the brake device and is released from the restraint may also move in a runaway manner.

Incidentally, as shown in, for example, Japanese Patent Laid-Open No. 61-166768, there is provided a structure in which a plurality of carriers (movable bodies) are connected and moved backward, 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 make it possible to form the body of the movable body in a slender and compact shape, and to ensure smooth (train-like) movement of the movable body group even in a fixed route having a curved route portion. In addition, it is a point to provide a transfer facility using a movable body, which can surely perform the movement and can always perform movement without runaway regardless of the number of movable bodies.

[0010]

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. In addition to providing a pair of guided devices supported and guided on the other side, the remaining frame body is provided with guided devices on the free end side, and the front and rear ends of the main body are formed as abutting portions, and are positioned at the front and rear ends of the main body. One of the guided devices is provided with an engaged body, and the other is provided with an engaging body that is engageable with and disengageable from the engaged body, and has a feed roller that is in contact with the passive surface in the fixed path. A feeding device is provided.

In the transfer facility using movable bodies according to the second 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, the movable body only needs to be provided with 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 feeding device, the feed roller that is forcibly rotating is brought into contact with the passive surface, so that the feeding device can apply a propulsive force to the movable body to move on a fixed path. .

At that time, in the straight path portion of the constant path,
The main body of each movable body, that is, each frame body can be moved in a linear posture in plan view and side view, and the contact portion of the succeeding movable body is brought into contact with the contact portion located in the widthwise central portion of the preceding movable body. By contacting each other, movement can be performed in a dense train. Also, in the left and right and up and down curve path parts, each frame body can be moved in a bent posture along the curve at the connecting device,
At that time, the bending is performed by relative rotation via the connecting device.

Further, since the engaging body is engaged with the engaged body in the state where the abutting portions are brought into contact with each other, for example, when the preceding movable body attempts to run away, its engagement connection causes The subsequent movable body can prevent runaway.

According to the structure of the second aspect of the present invention described above, the object to be conveyed is supported by the intermediate frame body, and
By supporting and guiding the guided devices provided on the front and rear frame bodies on the rails, the movable body can always be stably moved.

[0016]

In FIG. 13, a feeding device 40 for applying a running force to the movable body 10 by acting on the passive surface 15 is provided at a predetermined position on both linear path portions 5a. As shown in FIGS. 9 and 10, the feeding device 40 has a vertical axis 42 provided upright on a base body 41 continuous from the machine frame 2 on the outer side of the rail 3. A support member 44 is attached to the vertical axis 42 via a bearing 43 so as to be swingable around a vertical axis 45.

A rotation drive device (motor or the like) 46 is disposed on the support member 44, and an output shaft 48 taken out upward from a speed reducer 47 interlocked with the rotation drive device 46 is attached to, for example, a urethane feed roller. 49 is fixed. The rotation driving device 46 applies the feed rotational force A to the feed roller 49. The support member 44 integrally has a bracket 50 extending forward, and the support member 44 is provided between the bracket 50 and the base body 41.
A cylinder device 51 for swinging is provided.

Therefore, by operating the cylinder device 51, the support member 44 can be swung around the longitudinal axis 45, and the feed roller 49 can be moved into contact with or separated from the one passive surface 15. At that time, in order to regulate the position approaching the maximum, a stopper body 52 is continuously provided from the support member 44, and a stopper body 53 with which the stopper body 52 can come into contact is positionally adjusted to the base body 41. It is provided freely. A stationary roller 54, which is opposed to the feed roller 49 and is in contact with the other passive surface 15, is provided via a vertical axis 55 so as to freely rotate.

As shown in FIG. 13, 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.

Next, in the above-described first embodiment, the movable body 10
The moving work will be described. For example, the delivery device
The movable body 10 sent out by operating the 65 in the same manner as the later-described feeder 40 is moved in a state in which the feeder 40 side is in a receiving posture.

At this time, as shown in FIG. 4, the contact portion 90 at the rear end portion 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 The abutting portion 80 of the front end portion of the movable body 10 that has been fed into contact, that is, both arc surfaces
The rollers 83, 84 come into contact with 93, 94 from the rear side, whereby the movable body 10 group is moved by the feeding force of the feeding-in / out device 65. At this time, the engaging body 76 is engaged with the engaged member 75 of the engaged body 70 from above.

The above-mentioned feeding by the feeding / feeding device 65 is stopped when the front end of the corresponding movable body 10 enters the feeding device 40. At this time, the cylinder device 51 of the feeding device 40 is extended to swing the support member 44 outward about the longitudinal axis 45, so that the feeding roller 49 moves from the passive surface 15 as shown by the phantom line in FIG. It is separated. Therefore movable body
The 10 transfers (imports) will be carried out without any problems.

After that, the feed roller 49 is moved closer to the passive surface 15 by pressure in contact with one of the passive surfaces 15 as shown by the solid line in FIG. 9, and the other passive surface 15 is brought into contact with the stationary roller 54. 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, the guided devices 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 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 feeding device 40 is stopped, the cylinder device in the braking device 60 is contracted, and the braking roller 61 is separated. Then, in synchronism with the feeding movement of the 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 on the opposite side of the feeding roller 49. It is driven to rotate.

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 of being subjected to the braking action. Therefore, a plurality of movable bodies 10 are provided between the feeding device 40 and the braking device 60. However, they are aligned in a dense back-pushed state without creating a gap between the front and rear ends thereof. The braking action of the braking device 60 is stopped before and after the movement of the feeding device 40 is stopped.

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 above-described feeding device 40, the feed roller 49 is moved to the passive surface 15 of the front frame body 12.
To the passive surface 15 of the intermediate frame body 13 and the passive surface 15 of the rear frame body 14 sequentially.

At this time, the feed roller 49 is installed in 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. While being pushed and moved via 20, the rear frame body 14 is pulled and moved via the coupling device 20,
Further, when acting on the rear frame body 14, the intermediate frame body 13 and the front frame body 12 are pushed and moved via the coupling device 20.

In the train-like rearward movement on the fixed path 5 described above, in the linear path portion 5a, the main body 11 of each movable body 10, that is, each frame body 12, 13, 14 is linear in plan view and side view. As shown in FIGS. 4 and 6, since the contact portion 80 comes into contact with the contact portion 90 from directly behind, the pushing movement can be smoothly and reliably performed.

Further, in the curved path portion 5b, as shown in FIG. 11, the respective frame bodies 12, 13, 14 are pushed and moved in a bent state along the curve at the connecting device 20 in plan view. . As a result, in 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 obtuse angle of the contact portion 80 with respect to the contact portion 90 is obtuse. Therefore, the pushing movement can be smoothly and surely performed thereafter.

The bending is performed by relative rotation around the vertical pin 23 in the connecting device 20, as shown by the phantom line in FIG. Further, the displacement from the relatively linear shape to the refraction posture forming the relative angle Θ is performed by the arc surface 94 abutting on the roller 84.
However, by swinging the roller 84 in the horizontal direction while rotating the roller 84, smooth operation can be performed without causing friction or catching. At this time, the arcuate surface 93 escapes laterally with respect to the roller 83.

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. Since the engaging body 76 is engaged with the engaged body 70 in the state where the abutting portions 80 and 90 are in contact with each other, for example, a required number of elements are provided between the feeding device 40 and the braking device 60. When the preceding movable body 10 tries to move in a runaway manner without the movable body 10, the engagement and connection thereof can prevent the following movable body 10 from running away. Similarly, the movable body 10 that has left the braking device 60 and the restraint is released can also prevent runaway.

In the above embodiment, the engaging body 70 provided on the guided device 31 at the front end is engaged with the engaged body 76 provided on the guided device 32 at the rear end from above. An engaging body 76 is provided in the guided device 31 of
The engaged body 70 may be provided in the 32, and the engaging direction may be set arbitrarily such as lateral.

In the above embodiment, the rollers 83, 84 of the contact portion 80 are
Although a total of four arrangements of a pair of upper, lower, left and right are shown, the number and the arrangement are arbitrarily set, for example, omitting the upper one of the pair of upper and lower rollers 83.
Further, the auxiliary roller 95 and the auxiliary circular arc surface 85 can be omitted. Then, arcuate surfaces 93 and 94 are formed on one abutting portion 90, and rollers 83 and 84 are provided on the other abutting portion 80. In this, one abutting portion 90 is provided with a roller and the other abutting portion 90 is provided. An arc surface may be formed on the contact portion 80, and further, the rollers 83, 84 and the arc surface 93,
A simple contact surface may be used without providing 94.

In the above-described embodiment, the main body 11 of the movable body 10 is formed of three frame bodies 12, 13 and 14. However, in the first invention, the front frame body 12 and the intermediate frame body are provided. Two forms consisting of 13, two forms consisting of an intermediate frame body 13 and a rear frame body 14, three or more connecting one or more frame bodies in front of the front frame body 12 and behind the rear frame body 14. It may be in the form of.

In the above embodiment, the connecting device 20 has the horizontal pin 21 provided on the intermediate frame body 13 side and the vertical pin 23 provided on the front and rear frame bodies 12, 14 side.
This may be a type in which vertical pins are provided on the side of the intermediate frame body 13 and horizontal pins are provided on the front and rear frame bodies 12, 14 or a type in which they are freely rotatably connected by a ball joint.

In the above embodiment, in one of the feeding device 40, the feeding and feeding device 65 and the braking device 60, one feeding roller is used.
Although the 49 and the braking roller 61 are of a forced drive type and the stationary roller 54 and the receiving roller 54 of the other are idle type, all of both rollers may be a forced drive type. Furthermore, the other roller may also be configured to come into contact with and separate from the passive surface 15.

In the above embodiment, the rails 3 are arranged on the machine frame 2 from the floor 1 side. However, as shown by the phantom lines in FIG. 3, the rails 3 are arranged in the pit below the floor surface 1a. It may be arranged. According to this, the overall height including the movable body 10 can be formed low. Further, since the rail 3 does not have a portion requiring maintenance such as a drive chain, the rail 3 can be arranged in the pit below the floor surface 1a without any trouble.

In the above embodiment, the movable body 10 that can travel on the floor 1 side is shown, but it may be a movable body that is supported and guided by rails arranged on the ceiling side. Figure 14, Figure
Reference numeral 15 shows a second embodiment of the present invention. That is, the fixed path 5
A curved path portion 5b that is upward (or downward) in a side view is formed therein. Also in this case, the rear frame body 14 of the preceding movable body 10 and the front frame body 12 of the following movable body 10 are also seen in a side view. The relative angle Θ formed by and becomes an obtuse angle, and the abutting portion 80 abuts the abutting portion 90 at an obtuse angle, so that the pushing movement can be smoothly and reliably performed thereafter.

The bending is performed by relative rotation around the vertical pin 23 in the connecting device 20, as shown by the phantom line in FIG. Further, the displacement from the relatively linear shape to the refracting posture forming the relative angle Θ is performed by the arc surface 93 contacting the roller 83.
However, by swinging the roller 83 in the vertical direction while rotating the roller 83, smooth operation can be performed without causing friction or catching. At this time, the arc surface 94 escapes in the vertical direction with respect to the roller 84.
