DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a self-propelled transfer device in which a movable panel can be stored in a pair of parallel storage rails in a storage portion by being moved at substantially right angles in plan view. Things.

[0002]

2. Description of the Related Art As a prior art of this kind of storage section, Japanese Patent Publication No. 59-38391 discloses a chain or the like that only a pair of hanging supports attached via a pair of hanging shafts at the upper end of a movable panel. And conveyed to a storage rail.

[0003]

In this case, if the lower end of the movable panel is not restrained in the storage portion, the lower end of the movable panel is centered on the suspended support point restrained by inertia. The movable panel is moved in such a manner as to be inclined rearward in the traveling direction of the wide surface (front and back in the frontage direction), and when it is stopped next, the lower end of the movable panel swings back and forth in the traveling direction due to the reaction. Therefore, in order to prevent the lower end of the movable panel already stopped in the storage section from colliding with the lower end of the movable panel that is transported next to be stored, the time interval of transport of the movable panel must be increased. In addition, there is a problem that it takes time for the storing operation.

In order to solve this problem, Japanese Patent Laid-Open No. 51-90736 discloses a pair of front and rear suspension supports fixed to the upper end of a movable panel along a main rail having a horizontal H-shaped cross section. On the other hand, in a device for storing the movable panel in a storage section having a pair of parallel storage rails orthogonal to the main rail in a plan view, a transport vehicle driven to reciprocate along the pair of storage rails, A plurality of suspension rails movable by the carrier, the suspension rails being arranged in parallel with the main rail, and a lower end of a movable panel suspended by each suspension rail; And a chain mechanism for moving the lower part of the movable panel that drives the support rail in synchronization with the transport vehicle.

According to this configuration, when the movable panel is carried in and out of the storage section, the transport vehicle on the upper end side of the movable panel and the transport chain mechanism on the lower end side must be driven synchronously. In addition, there is a problem that the configuration becomes complicated. An object of the present invention is to solve these problems with a simple configuration and to provide a new self-propelled transfer device.

[0006]

In order to achieve the above object, the present invention relates to a storage position of a pair of parallel storage rails disposed on a ceiling of a storage portion, and a storage position intersecting the storage rails in a plan view. A self-propelled carrier that self-runs between the guide rails leading out of the section and is configured to carry in / out a movable panel disposed such that the wide surface is substantially perpendicular to the pair of storage rails in plan view. In the self-propelled carrier, a hook is rotatable so as to be attached to and detached from a pair of suspension shafts attached to a suspension support movable along the pair of storage rails and suspending a movable panel. On the other hand, a plurality of contact members that contact the wide surface of the movable panel are provided below the hook.

[0007]

According to this structure, when the movable panel is pushed and moved or retracted along the storage rail, if a pair of hooks are previously rotated to engage the suspension shaft, the movable panel is moved right and left at a position below it. Since the abutting body at a plurality of places such as a pair abuts on the rear face in the frontage direction of the movable panel, the wide face in the frontage direction of the movable panel can be restrained at at least four locations on the left, right, up and down. It can be pushed or pulled in a vertical position.

Therefore, it is possible to avoid an inclined state in which the lower end side of the movable panel is rearward in the traveling direction due to the inertia force during the movement. As a result, when the movable panel is stopped after being transported, it is possible to prevent a phenomenon that the movable panel swings back and forth around the upper end thereof, and collides with another movable panel at the storage position in the storage section. It is possible to eliminate the accident of being damaged due to damage.

In addition, when the moving panel is carried out of the storage section, the moving panel once stopped at the guide rail does not swing, so that the operation of immediately transporting the moving panel from the storage section to the outside can be quickly performed.

The actuator 56 is turned off at a position where the lock rod 54 does not fit with the engagement concave groove 52 on the control plate 51, and the lock rod 54 is pressed against the peripheral surface 53 by a spring force (not shown). In this state, the drive motor 50 is ON and the pivot 45 is rotating in the direction of arrow A. At this time, the operation arm 59 is separated from the contact plate 57, and the sensor 58 outputs an ON signal.

When the control plate 51 is further rotated and the operating arm 59 is kicked up by the contact plate 57, the sensor 58 outputs an OFF signal and the application of current to the drive motor 50 is stopped. Even in this state, the pivot 45 rotates due to the inertial force, but the lock rod 5 pressed against the peripheral surface by the spring force is applied.
When the tip end of the rail 4 naturally falls into the engaging groove 52, the rotation of the control plate 51 and thus the pivot 45 is forcibly stopped at that position, and the longitudinal direction of the switching rail 16 is changed to the main rail 2 direction. Or, it matches the direction of the storage rail 7 (8).

Next, to start rotation, the actuator 5
6 is turned on to retract the lock rod 54, the drive motor 50 is turned on substantially simultaneously, and after an appropriate time for the lock rod 53 to face the peripheral surface, the operating arm 59 separates from the contact plate 57 and issues an OFF signal. Because of this, actuator 5
6 is turned off. The configuration of the self-propelled carrier in the self-propelled carry-in / out device 15 will be described in detail with reference to FIGS. 7 and 11 to 14.

It is preferable that a cushioning material such as rubber is stretched on the front end surface of the base material. When the movable panel 1 is pushed and moved or retracted along the storage rails 7 and 8 by the self-propelled loading / unloading device 15, if the suspension shafts 20 and 20 are engaged with the pair of hooks 19 and 19 in advance, the movable panel 1 is moved downward. Since the pair of abutting members 71 abut against the rear surface of the movable panel 1 in the frontage direction, the wide surface in the frontage direction of the movable panel 1 can be restrained at four locations, left, right, and up and down. It can be pushed or pulled in a substantially vertical state.

Therefore, it is possible to avoid an inclined state in which the lower end of the movable panel 1 is rearward in the traveling direction due to the inertia force during the movement. As a result, when the moving panel stops after transport,
It is possible to prevent the movable panel 1 from swinging back and forth around its lower end with the upper end as a center.
It is possible to eliminate an accident that the movable panel 1 is damaged by colliding with another movable panel 1 at the storage position in the interior. When the movable panel 1 is temporarily stopped at six guide rails when it is carried out of the storage section 3, the swing of the movable panel 1 is caused by the pair of hooks 1.

Therefore, even if the direction is changed immediately , it is possible to prevent an accident that the hanging support 21 falls off from the 16 switching rails, and it is possible to quickly carry out the transfer operation in the main rail 2 direction. It works.

Numeral 72 indicates that the contact body 71 is a movable panel 1
This is a shock absorber for reducing the impact when the contact is made. Reference numeral 73 denotes a contact-type sensor arm for detecting a state in which the contact members 71, 71 are substantially in contact with the rear surface of the movable panel 1 in the frontage direction. A signal is issued to activate the actuator 18.

In FIG. 1, reference numeral S1 denotes a sensor for detecting that the movable panel 1 has entered the entrance 3a of the storage section 3, and reference numeral S2 denotes that the movable panel 1 has stopped at the stop device 13. A sensor that senses, symbol S3 is a sensor that senses that the transport device 14 is in the retracted position (position away from the storage unit 3), and a symbol S4 is that the transport device 14 is in the forward position (position near the storage unit 3). The sensor S5 is provided at the position of the auxiliary rail 11 to detect that the movable panel 1 is at the position of the guide rail 6, and these sensors S1 to S5 may be of a contact type. , A non-contact sensor such as a light transmission type or a light reflection type.

With this configuration, when a main switch provided on a control panel (control box) 75 for sequence control provided near the entrance 3a of the storage section 3 is depressed, the sensors S1 to S5, 58, and 74 operate. State. Next, by pressing a panel storage command switch (not shown), the transport device 14 stops at the position of the sensor S3 and waits in the solid line state (retreat position) in FIG. Then, the movable panel 1 pressed by the worker is moved to the entrance 3a of the storage section.
When the vehicle moves forward, the sensor S1 is turned on, thereby actuating the actuator of the stopping device 13, and the pair of regulating members approach and stop in advance so as to sandwich the main rail 2 from the left and right outer sides. In this state, the operator pushes the moving panel 1 further. As a result, the approaching suspension body 21

1 to prevent the moving panel 1 from passing therethrough.

The sensor S1 or the sensor S2
In response to the ON signal, the pair of direction change devices 4 and 5 are operated to change the posture of the switching rail 16 so that its longitudinal direction is in line with the longitudinal direction of the main rail 2 and stand by in that state. I do. Further, the self-propelled carry-in / out device 15 stands by at a position where the whole of the self-propelled carry-in / out device 15 is retracted to the auxiliary rails 9 and 10.

When the sensor 21 senses the stopped front suspension member 21 by the sensor S2, the actuator 40 of the transfer device 14 at the retracted position is operated, and the hook member 17 causes the rear suspension shaft 20 of the movable panel 1 to move. grab. At about the same time, the restricting body of the stopping device 13 retreats to allow the suspension support 21 to pass through. When the transport device 14 moves forward in this state, the movable panel 1 is pulled. When detected by the sensor S4, the transport device 14 stops at that position. As a result, the movable panel 1 is located at the position of the switching rail 16 in the direction change device 5 after the suspension support 21 on the front side of the movement passes through the guide rail 6, and the suspension support 21 on the rear side of the movement is 4 at the position of the switching rail 16. In this state, the hook body 17 is retracted to release the engagement with the suspension shaft 20, and the transport main body 34 is moved toward the original position along the sub rail 12. After passing through 13 places of the stop device, the stop device 13 is closed again with the two restrictors approaching the side of the main rail 2 again.

Moving panel 1 along guide rail 6
When the front end detects that the sensor S5 has approached the sensor S5, the direction change devices 4 and 5 are operated to rotate the pivot 45 by 90 degrees, and the longitudinal direction of the switching rails 16 and 16 becomes the longitudinal direction of the storage rails 7 and 8. Change the posture so that it matches. Next, the self-propelled loading / unloading device 15 is moved closer to the back side of the movable panel 1 stopped at the six guide rails, and the sensor arm 73 detects the movable panel 1 and stops. Is activated and both left and right hooks 1
9 is horizontally rotated, and a pair of suspension shafts 20, 20 of the movable panel 1 are gripped from inside. At this time, as described above, the pair of abutting members 71 abut on the rear surface of the wide surface of the movable panel 1 and, together with the hooks 19, the posture of the movable panel is set to a substantially vertical state at four positions in the upper, lower, left and right directions. Can be restrained,
In this state, the self-propelled carry-in / out device 15 is advanced, and the movable panel 1 is pushed toward the tip of the storage rails 7 and 8 to be stored. The fact that the movable panel 1 cannot advance further at the end of the storage section is determined by detecting an increase in the load of the drive motor 65 of the self-propelled carry-in / out device 15, and after stopping at that position, the auxiliary rails 9 and 10 are stopped. The self-propelled carry-in / carry-out device 15 retreats to a position and waits. This retreat waiting is sensed by a sensor (not shown), and the pair of direction change devices 4 and 5 are operated to rotate the switching rail 16 by 90 degrees, and a display indicating that the next movable panel 1 can be carried in appears on the control panel 75. By repeating this, the moving panel 1 can be stored one after another.

In contrast to the above, the moving panel 1 is moved to the main rail 2 side.
Is pressed, the carry-out command switch on the control panel 75 is pressed. Then, the self-propelled loading / unloading device 15 moves forward, and the pair of hanging shafts 20, 20 of the movable panel 1 supported by the storage rails 7, 8 is gripped by the hooks 19, 19. And the direction change device 4,
After moving to the position 5, the direction change devices 4 and 5 are operated to change the directions of the switching rails 16 and 90 by 90 degrees. Next, the transport device 14 is advanced after being advanced to approach the direction changing device 4 at the 12 sub rails, and then stopped. Then, the actuator 40 is operated, and the hanging shaft 20 of the movable panel 1 is grasped by the hook body 17, The transport device 14 is moved so that one end of the movable panel 1 comes out of the entrance 3a. From now on, the operator manually pulls the moving panel 1 and sends the moving panel to a predetermined position.

The self-propelled loading / unloading device 15 is provided with a distance sensor 76 to detect the distance between the self-propelled loading / unloading device 15 and the movable panel 1 and, when the distance becomes short, the self-propelled loading / unloading device 15 moves. If the self-running speed of the carry-in / out device 15 is controlled to be lower, safer conveyance can be performed. In the illustrated embodiment, the pair of storage rails 7 and 8 are extended only on one side of the guide rail 6. However, the auxiliary rails 9 and 10 in the above embodiment are elongated and the portion is moved to the movable panel. 1 can be configured to be a storage unit,
In this case, an actuator 18, a hook 19, an abutment body 71, a shock absorber 72, a sensor arm 73, a limit switch 74, and a distance sensing sensor 76 are provided before and after the self-propelled carry-in / out device 15, and are reverse to those in the illustrated embodiment. What is necessary is just to move the self-propelled carrying-in / out device 15 back and forth in the direction, and there is an effect that a large number of movable panels can be carried in / out of the storage unit by one self-propelled carrying-in / out device.
