Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier device in which a load transfer mechanism is swingably supported on a traveling carriage that travels along a transfer track.

[0002]

2. Description of the Related Art Conventionally, in an assembly line of a factory or the like, an elevated monorail is provided on a ceiling portion, and while a traveling carriage is traveling on this monorail, various cargoes are loaded by a load transfer mechanism supported by the traveling carriage. A transport device is used to transport the. In such a transfer device, the load transfer mechanism is generally hung on the traveling carriage and swingably supported by the traveling carriage. In other words, when the traveling carriage travels on the slopes of the monorail uphill or downhill, the load transfer mechanism is allowed to swing with respect to the travel carriage, thereby maintaining the load transfer mechanism in a horizontal state. I try to carry it.

By the way, in such a device in which the load transfer mechanism is swingably supported with respect to the traveling carriage, it is advantageous in that the load transfer mechanism can be horizontally maintained on the slope of the monorail as described above. On the other hand, since the load transfer mechanism easily swings during traveling, there is an adverse effect of impairing traveling stability.

Therefore, recently, a steadying mechanism such as a damping mechanism using a damper member and a mechanism using fixed friction is provided to suppress unnecessary swinging of the load transfer mechanism with respect to the traveling carriage.

[0005]

By the way, according to the steady rest mechanism described above, it is possible to suppress unnecessary swinging of the load transfer mechanism with respect to the traveling carriage as described above, but the load transfer mechanism is not always horizontal. Could not always be maintained. That is, when a load is biased toward the load transfer mechanism, the load transfer mechanism is always inclined with respect to the traveling carriage due to the weight of the load. Even if unnecessary shake is suppressed, the tilt of the load transfer mechanism remains unresolved.

However, if the load transfer mechanism is kept tilted in this way, the loading and unloading operation of the load often occurs. Therefore, if the load transfer mechanism is biased, the load is loaded unevenly. Therefore, even if the load transfer mechanism tilts with respect to the traveling carriage, the load transfer mechanism is forcibly maintained in a horizontal state at a predetermined place of the monorail such as a place of unloading. It is necessary to ensure proper loading and unloading of luggage.

The present invention has been made in order to solve the above-mentioned problems, and a state in which the load transfer mechanism is allowed to swing with respect to a traveling carriage, and a state in which the load transfer mechanism is prevented from swinging, the load transfer mechanism is forcibly leveled. It is an object of the present invention to provide a transfer device that can switch to a state in which the load is maintained and that can appropriately transfer and unload cargo.

The lock mechanism and the cam are engaged with each other to prevent the load transfer mechanism from swinging with respect to the traveling carriage, and the cushion mechanism holds the connecting shaft between the traveling mechanism. The truck has a pair of dampers arranged respectively on the front and rear sides in the traveling direction of the truck, and a pair of contact members provided on the cargo transfer mechanism corresponding to the dampers. The transfer mechanism Are those configured to attenuate oscillation of either side of the damper collides with the corresponding contact member integrating load transfer mechanism by moving.

[0012]

According to the invention described in claims 1 to 4, when the traveling carriage passes through the uphill portion and the downhill portion of the conveyance track, the swinging restraining arm is held at the retracted position. As a result, the load transfer mechanism swings with respect to the traveling carriage so that the load transfer mechanism is in a horizontal state according to an angle change of the traveling carriage due to movement from the horizontal portion to the slope portion or movement from the slope portion to the horizontal portion. On the other hand, at a predetermined location on the transportation track, such as the loading / unloading location of luggage, the swinging restraint arm is held in the operating position,
This forces the load transfer mechanism to remain horizontal.

There is. At this time, the rocking restraint arms 46 are adapted to rotate in mutually different directions. As the motor 50 is driven to rotate in the forward and reverse directions, the rocking restraint arms 46 are shown in solid lines in FIG. As shown in FIG. 5, the structure is configured to be rotationally displaced between an operating position that projects vertically downward from the support bracket 17 and a retracted position that is stored inside the support bracket 17 as shown by a two-dot chain line in FIG. .

Then, in the state in which each of the rocking and restraining arms 46 is held at the operating position in this way, the pressing roller 47 of each of the rocking and restraining arms 46 is pressed against the upper surface portion of the elevating device 5, and as a result, The swinging of the lifting device 5 and the handling mechanism 6 with respect to the traveling carriage 4 is restrained, and the handling mechanism 6 is forcibly maintained in a horizontal state with respect to the traveling carriage 4, while the swing restraining arms 46 described above are held. In the state where is held in the retracted position, the lifting device 5 and the handling mechanism 6 are allowed to swing with respect to the traveling carriage 4.

By the way, a detection piece 48 for detecting the operation of the horizontal maintaining device 45 is fixed to the support shaft 46a which supports each of the swinging restraining arms 46, and a photosensor, for example, for detecting this is also provided. An operation detection sensor 49 including the above is attached to the support bracket 17, and the operation detection sensor 49 detects the detection piece 48 to detect the operation state of each rocking and restraining arm 46.

In the monorail type transporting device constructed as described above, the control unit 11 is equipped with a control unit mainly composed of a microcomputer, and the transporting operation in the monorail type transporting device is integrally controlled by this control unit. It is supposed to be done.

In particular, with regard to the leveling device 45,
It is controlled to automatically operate in a certain section of the monorail track. Here, an example of the control is shown in FIG.
Will be described with reference to the flowchart of FIG.
At this time, as shown in FIG. 7, the traveling carriage 4 reaches the horizontal portion 1a from the climbing portion 1b of the monorail 1, and the horizontal portion 1a
The loading / unloading operation of the luggage is performed at the work station S provided at a predetermined position of the work station, and the control marks such as the operation command mark Pa, the work command mark Pb, and the retract command mark Pc provided near the work station S are run. The detection means (not shown) of the carriage 4 detects the mark, and a predetermined operation is performed based on the mark detection.

First, in the monorail type transport device, while the traveling carriage 4 is traveling on the slope 1b of the monorail 1, the horizontal maintaining device 45 is in a non-operating state, that is, each of the swinging restraining arms. 46 is in the retracted position, which allows the lifting device 5 and the handling mechanism 6 to swing with respect to the traveling carriage 4, and the handling mechanism 6 is maintained horizontally as shown in the figure.

When the traveling vehicle 4 further travels and the operation command mark Pa is detected from the climbing portion 1b of the monorail 1 to the horizontal portion 1a, the horizontal maintaining device 45 is activated based on this detection. That is, each of the swing restraint arms 46 is rotationally displaced from the retracted position to the operating position, and the completion of the operation of each swing restraint arm 46 is determined (steps S1 and S2).

At this time, if one or both of the rocking and restraining arms 46 does not operate properly, specifically, the detecting pieces of the rocking and restraining arms 46 within a predetermined time from the start of the operation of the horizontal maintaining device 45. When 48 is not detected by the operation detection sensor 49 (NO in step S2), the process proceeds to step S10, and after the error is output here, the traveling of the traveling vehicle 4 is stopped (step S11).

On the other hand, when both swing restraining arms 46 have properly operated (NO in step S2), the traveling carriage 4 continues to travel, and when the work command mark Pb is detected, it stops based on this detection. That is, the traveling carriage 4 is stopped at the work station S (step S3, step S
4). Then, in the work station S, loading / unloading work is performed while the handling mechanism 6 is being raised / lowered by the lifting / lowering device 5, and when the work is completed, the traveling carriage 4 is started to travel again (step S5). Step S6).

In this way, when the traveling carriage 4 starts traveling after the work at the work station S is completed and the retract command mark Pc is detected, the leveling device 45 is again actuated based on this detection, whereby the above described Each swing restraint arm 46 is rotationally displaced from the operating position to the retracted position, and it is determined whether each swing restraint arm 46 has been retracted (steps S7 and S8).

At this time, if one or both of the rocking and restraining arms 46 do not retreat properly, specifically, the detecting pieces of the rocking and restraining arms 46 within a predetermined time from the start of the operation of the horizontal maintaining device 45. When the detection of the operation detection sensor 49 with respect to 48 is not canceled (NO in step S8), the process proceeds to step S10, and after an error is output here,
The traveling of the traveling carriage 4 is stopped (step S11).

On the other hand, when both swinging restraining arms 46 are properly pivotally displaced to the retracted position (YE in step S8).
In S), the carriage 4 goes to the next work station.
Is continued and the process returns to step S1.

In the monorail type transporting device constructed as described above, the leveling device 45 allows the handling mechanism 6 to oscillate with respect to the traveling carriage 4 and forbids it. Since the switching mechanism is switchable and the handling mechanism 6 is kept horizontal in this swinging prevention state, it is possible to more appropriately carry the load and unload the work.

That is, in the conventional monorail type transfer device of this type, it is possible to prevent unnecessary swinging of the handling mechanism with respect to the traveling carriage, but when loads are unevenly loaded on the handling mechanism, Due to the weight of the luggage, the handling mechanism is always inclined with respect to the traveling carriage, which may hinder the loading and unloading operation of the luggage at the work station or the like. However, according to the monorail type transporting apparatus of the above-mentioned embodiment, even if a load is unevenly loaded on the handling mechanism 6 and the elevating device 5 and the handling mechanism 6 are inclined with respect to the traveling carriage 5, the situation may occur. When the leveling device 45 is operated at a predetermined work station or the like, the swinging restraining arm 46 is pressed against the upper surface of the lifting device 5 as the swinging restraining arm 46 rotates, and the swing restraining arm 46 is pressed against the traveling carriage 4. Since the inclinations of the lifting device 5 and the handling mechanism 6 are forcibly corrected, the loading and unloading operation of the load can be performed while the handling mechanism is always kept horizontal, and the loading and unloading of the load is appropriately performed. be able to.

Moreover, as described above, each rocking restraining arm 4
6 in the operating position, each rocking restraining arm 4
Since the pressing roller 47 of 6 presses against the upper surface of the lifting device 5 to restrain the lifting device 5 and the handling mechanism 6 from swinging, for example, when loading and unloading heavy objects on the handling mechanism 6. Even if there is, it is possible to surely press the swing of the handling mechanism 6 to perform the loading / unloading work, and also in this respect, the loading / unloading work of the load can be performed more appropriately.

The horizontal maintaining device 4 in the above embodiment
Reference numeral 5 is an embodiment of a horizontal maintaining device, and its specific configuration can be appropriately changed without departing from the gist of the present invention. For example, in the above embodiment, the horizontal maintaining device 4
5 is composed of a pair of swing restraining arms 46 and a plurality of timing gears 52a to 56a, 52b to 56b meshing with each other and an operating mechanism including a motor 50.
The actuating mechanism may be configured by a combination of a gear and a chain member that is stretched around the gear, or a belt member. Further, in addition to the configuration in which the swinging restraining arm 46 is rotated by using the motor 50 as a driving source as in the embodiment, for example, an air cylinder is applied as a driving source, and air pressure suction / discharge to / from the air cylinder is switched. The swinging restraining arm 46 may be configured to advance or retreat in the vertical direction directly or indirectly via a gear or the like.

The control method shown in the flow chart of FIG. 6 is also an example of the control method of the monorail type transfer apparatus, and the operation timing of the horizontal maintaining apparatus 45 can be changed appropriately. For example, in the control of the above-described embodiment, the operation command mark Pa and the retraction command mark Pc are provided in a certain section including the work station S, and the horizontal maintenance device 45 is operated based on the detection of these. Based on the detection of the command mark Pb, the horizontal maintenance device 45 may be controlled to operate immediately before the traveling carriage 4 is stopped at a predetermined work station S, or immediately after the travel carriage 4 is stopped, and immediately after the work at the work station S is completed. I do not care.

[0047]

As described above, according to the present invention, the swing restraining arm is provided, and in the state in which the swing restraining arm is held at the operating position, the load shifting mechanism is prevented from swinging with respect to the traveling carriage to transport the load. While the mechanism is kept horizontal, the load transfer mechanism is allowed to swing with respect to the traveling carriage while being held in the retracted position.Therefore, on the slope of the transport track, the swing restraint arm is held in the retracted position. The load transfer mechanism is allowed to swing, which allows the load transfer mechanism to be transported while being kept horizontal, while the load transfer mechanism can be held at a predetermined position on the transfer track, such as a loading / unloading place. The arm can be held in the actuated position, which forces the load transfer mechanism to remain horizontal. Therefore, it is possible to properly transport the cargo regardless of the slope or the horizontal portion of the transportation track, and it is possible to appropriately load and unload the cargo without being influenced by the deviation of the cargo to the cargo transfer mechanism.
