Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a plurality of accommodating sections, each of which includes a pair of accommodating rails, at one end of the main rail disposed on the ceiling along the longitudinal direction of the main rail. In a moving panel device in which individual self-propelled moving panels suspended in the main rail can be transferred between the main rail and each storage unit, the moving panels are arranged in parallel, and the moving panels are arranged in the main rail and each storage unit. The present invention relates to a transfer control device for smoothly transitioning between and.

[Prior art]

Conventionally, a moving panel is hanged freely on a main rail provided on a ceiling, and a pair of two storage rails are connected to the end of the main rail to form a storage unit, and each moving panel is stored from the main rail. Various moving panel devices have been devised in which the moving panel device is moved to a rail and stored in a storage portion or is sequentially extended from the storage portion to a main rail.

For example, in Japanese Patent Laid-Open No. 55-59288, two pairs of storage rails are connected to one end of a main rail, and one endless transport is carried from one storage rail along both longitudinal directions of the main rail. While arranging the chain, a chain sprocket with a torque limiter is provided on the suspension support attached to the upper end of each moving panel, and the transport chain is moved with the chain sprocket always meshed with the transport chain. A technique is disclosed in which each moving panel is capable of reciprocating between a storage rail portion and a main rail.

[Problems to be solved by the device]

By the way, in the case where the number of moving panels is too large to fit in one storage unit, or when the depth of the storage unit cannot be increased due to the structure of the building, it is necessary to provide a plurality of storage units. As described above, in the case of moving all the moving panels all at once by using one transport chain, it is impossible to provide a plurality of storage sections because only one storage section can be provided.

In this regard, for example, as described in Japanese Utility Model Laid-Open No. 60-41471, a motor is built in each moving panel so that each moving panel can move independently and the main rail It is conceivable that a plurality of storage units each consisting of a pair of storage rails are provided in parallel at one end of the storage unit so that the moving panel can be independently moved to each storage unit.

However, when a plurality of storage units are arranged side by side along the longitudinal direction of the main rail in this way, it is necessary to allow the moving panel to pass at the storage unit other than the storage unit provided near the end of the main rail. Therefore, in a configuration in which a plurality of storage units are simply arranged side by side, it is troublesome to stop the moving panel at a position where it can be moved to an arbitrary storage unit, so that the storage work becomes very troublesome and inefficient. Occurs.

The present invention is intended to solve the problem that occurs when a plurality of storage units for storing a self-propelled moving panel are arranged side by side.

[Means for Solving the Problems]

To achieve this object, according to the present invention, a pair of front and rear runners projecting upward from the upper end surface of a moving panel are movably fitted and inserted into a main rail having a downward opening in a cross section, which is installed in the main rail. At one end, a plurality of storage units, each of which is composed of a pair of storage rails extending in a direction intersecting with the main rail so that the runner of the moving panel can be transferred from the main rail, are connected in parallel along the longitudinal direction of the main rail. In addition, in a self-propelled moving panel equipped with a power-type driving device that makes the moving panel self-propelled along the main rail, in the part between the adjacent storage sections of the one end of the main rail, A movable stopper that engages the runner and stops the moving panel at a position where it can be moved to an arbitrary storage part is provided so as to be engaged with and disengaged from the runner by the movement. A stop switch that operates when the panel comes to a position where it stops at the stopper is provided, and the stop switch and the drive device for the moving panel are related so that the drive device stops the traveling of the moving panel by the operation of the stop switch. It was configured to do.

[Action / effect]

In this configuration, if the movable stopper is projected so that it can contact the runner of the moving panel, the moving panel traveling on the main rail contacts the stopper and the driving by the drive means is stopped by the stop switch. By doing so, the stopper is stopped at a position where it can be moved to the storage part at a certain location, and therefore each moving panel can be moved to an arbitrary storage part by projecting / retracting the stopper.

Therefore, according to the present invention, a plurality of moving panels are arranged along the longitudinal direction of the main rail, such as when there are a large number of moving panels or when the depth of the storing section cannot be increased due to structural restrictions of the building. When installed, a large number of moving panels that have been self-propelled on the main rail can be sequentially stored in the next storage unit after they have been stored in one storage unit. To store the panel,
It has the effect that it can be performed accurately and efficiently.

By moving to the 2b ', the moving panel P is transferred from the main rail 1 to the storage sections 3 and 3'. On the upper surface of each roller receiving plate 7 in each runner 5,
A protrusion 9 with a rotor 9a is provided.

Reference numeral 10 shown in FIGS. 1 and 2 denotes a first storage / conveyance device for moving the moving panel P into and out of the first storage portion 3 from the main rail 1, and reference numeral 10 ′ denotes the moving panel P.
2 shows a second storage / conveyance device that moves the main rail 1 into and out of the second storage part 3 ', and both storage part transfer devices 10 and 10' are a pair of storage devices arranged along the upper surface of the storage rail 2. It is composed of an endless chain 11, sprocket wheels 12 and 13 around which the endless chain 11 is wound and supported, and a drive motor M1 capable of forward and reverse rotation. The specific configuration is as follows (see FIGS. 1 to 5).

That is, the drive shaft 15 is rotatably supported via the bracket above the rear portion of each intersection of the storage rail 2 and the main rail 1, and the sprocket wheels 13 are fixed to both ends of the drive shaft 15. The long shaft 16 is rotatably supported on the upper surfaces of the storage rails 2 near the free ends thereof via brackets, and the sprocket wheel 12 is fixed to the long shaft 16.

Then, the pair of sprocket wheels 12, 13

Is configured to be rotatable in both forward and reverse directions. In this case, a cutout for inserting the endless chain 11 is formed on the top plate of the vertical plate 1a of the main rail 1 behind the intersection with each storage rail 2 and on the top plate near the free ends of both storage rails 2. Holes 14 and 14 'are provided.

Further, a pair of front and rear holding bodies 19 are attached to the outer peripheral surface of each endless chain 11 with a proper pitch t, and the holding bodies 19 hold the projections 9 on the upper surface of each runner 5 from above. Therefore, when the drive motor M1 is rotated in the normal direction, the endless chain 11 rotates in the direction of arrow C, and the moving panel P
Moves toward the back of the storage rails 3, 3 ', and the drive motor M
When 1 is reversed, the endless chain 11 rotates in the direction of arrow D, and the moving panel P is transferred toward the main rail 1.

Reference numeral 31 shown in FIG. 3 indicates a drive device provided on each moving panel P in order to make each moving panel P self-propelled.

As shown in FIGS. 3 to 7, the drive device 31 includes a forward-reverse rotatable self-propelled motor M2 with a speed reducer built in the moving panel P and a drive shaft 33 above the moving panel P. The chain sprocket 34 arranged, the transmission mechanism 32 for transmitting the power of the self-propelled motor M2 to the drive shaft 33, and the three trolley wires 26 arranged along the main rail 1.
And a current collector 35 provided at the upper end of the moving panel P for receiving electric power from the moving panel P, and the chain sprocket 34 is configured to rotate freely forward and backward with the forward and reverse rotation of the self-propelled motor M2. is doing.

A fixed chain 22 is provided along the main rail 1, and the fixed chain 22 is meshed with a chain sprocket 34 of a drive unit 31 so that each moving panel P is self-propelled along the main rail 1. Is configured as follows. In this case, as shown in FIG. 6, each chain sprocket 34 is provided with a torque limiter 44,
The chain sprocket 34 is configured to idle when a load over a certain level is applied.

As shown in FIG. 6, each of the trolley wires 26 is protected by an electrically insulating material separator 28 and fixed to the inner surface of the support member 30 via an insulating wire holder 29. In this case, as shown in FIG. 7, the trolley wire 26 has both the storage parts 3, 3 ′ of the trolley wire 26 by inserting the insulator 25 from the second storage part 3 ′ to the front part as appropriate. The terminating portion 26 'including the intersection with and is divided into an appropriate range, and the power supply to the terminating portion 26' is set to O.
N / OFF is enabled.

The current collector 35 is composed of an arm 36 arranged on the upper surface of the moving panel P and current collectors 37 that can come into contact with the trolley wires 26. The arm 36 is configured to be horizontally rotatable by pivotally supporting the base of the arm 36 on a pillar 40 provided on the upper surface of the moving panel P, and each of the current collectors 37 is provided at the tip of the arm 36. The mounted bracket 38 is axially supported by a shaft 39 so as to be vertically movable and horizontally rotatable. Further, by mounting a spring 42 between the restricting piece 41 fixed to the support column 40 and the base of the arm 36, each current collector 37 is urged in the direction of contacting the trolley wire 26. .

Further, as shown in FIG. 6, the fixed chain 22 has a lower surface and a rear surface abutted on a support body 21 having a substantially L shape in a side view, which is fixed to a lower surface of one runner receiving piece 1c of the main rail 1. The support 2 is provided with the screws 2
It is fixed at 3.

In this case, as shown in FIG. 6, in the fixed chain 2, a vacant space 24 in the rear of an appropriate range near the portion where the chain sprocket 34 disengages when the moving panel P moves from each storage rail 2. Although the chain sprocket 34 is formed as a cushioning portion when meshing with the fixed chain 22, the void 24 may be filled with a cushioning material such as rubber.

In the embodiment, as the self-propelled means of the moving panel P, the fixed chain 22 and the chain sprocket 34 are engaged with each other. However, other self-propelled means such as a combination of a rack and a pinion is adopted. It goes without saying that it is okay.

Reference numeral 50 shown in FIG. 1, FIG. 8 and FIG. 9 is a stop means for stopping the moving panel P traveling toward the end of the main rail 1 at a position where it can be moved to the second storage portion 3 ′. Indicates.

This stopping means 50 is a plate-like reciprocating stopper 51.
The stopper 51 is provided in the main rail 1 through the through holes 53 formed in the vertical plates 1a and 1b of the main rail 1, and the stopper 51 can be rotated forward and backward. Screw shaft 52 fixed to the main shaft of M3
The stopper 51 can be reciprocated toward the inside of the main rail 1 by the forward and reverse rotations of the control motor M3 so as to be engaged with and disengaged from the runner 5 of the moving panel P.

When the stopper 51 is projected into the main rail 1, the tip of the stopper 51 is located on both vertical plates 1b of the main rail 1.
The strength of the stopper 51 can be improved by fitting the engaging hole 54 formed in the stopper 51.

With such a configuration, in a state in which the control motor M3 is rotated in the reverse direction and the stopper 51 is retracted, the moving panel P can travel to the end (one end) of the main rail 1, while the control motor M3 is rotated in the normal direction (embodiment). When the stopper 51 enters the inside of the main rail 1 by turning left), the runner 5 of the moving panel P traveling toward the end of the main rail 1 engages (contacts) the stopper 51, and the moving panel P is moved. Stops at a position where it can move to the second storage section 3.

Although the screw mechanism is used as the means for sliding the stopper 51 back and forth in the embodiment, it goes without saying that the means for reciprocating the stopper 51 may have another structure such as utilizing an electromagnetic solenoid. The stopper 51 may be engaged with and disengaged from the runner 5 by rotating horizontally instead of sliding back and forth.

The stopper 51 is provided with a stop switch (limit switch) L5 for the runner 5 so that the runner 5 abuts and operates when the moving panel P reaches a position where it can move to the second storage section 3 '. By connecting the power supply to the trolley wire 26 of the stop switch L5 so that the power supply to the terminal end 26 'of the trolley wire 26 is cut off by the operation of the limit switch L5, the rotation of the self-propelled motor 31 in the drive device 31 is prevented. Relate to stop.

Reference numeral 20 shown in FIG. 1 denotes a first storage unit control device for automatically moving the moving panel P into and out of the first storage unit 3, and reference numeral 20 'denotes a second storage unit 3'. 2 shows a second storage unit control device for automatically moving the moving panel P in and out.

Of these, the first storage unit controller 20 is provided with a main switch (not shown) for rotating the drive motor M1 forward and backward, and each moving panel P is transferred from the main rail 1 to the first storage unit 3. It is provided with a first limit switch L1 and a second limit switch L2 that are activated when retracted, and a third limit switch L3 and a fourth limit switch L4 that are activated when retracted each moving panel P,
It works as follows.

That is, the moving panel P that has traveled toward the terminal end of the main rail 1 (toward the arrow A direction) is
When located at the intersection with the storage part 3, the moving panel P abuts against a fixed stopper (not shown) and is stopped.
At the same time, the first limit switch L1 provided in the end portion of the main rail 1 is actuated, and the end portion 2 of the trolley wire 26 is
The power supply to 6'is turned off, the self-propelled motor M2 of the moving panel P located at the end of the main rail 1 is stopped, and the succeeding moving panel P is stopped before the second storage section 3 ', and then Drive motor M with some time lag
1 rotates in the forward direction, and the moving panel P located at the end of the main rail 1 is fed into the first storage portion 3.

When the movable panel P enters into the first storage portion 3 by a certain size t, the second limit switch L2 is actuated, the rotation of the drive motor M1 is stopped, and at the same time, the terminal portion 26 'of the trolley wire 26 is energized, The succeeding moving panel P, which is on standby in front of the storage section 3 ', travels and is stored in the first storage section 3 by the same operation as described above. By repeating this cycle, the n moving panels P are automatically stored in the first storage portion 3 in a state in which they are spaced from each other by a constant distance t.

On the contrary, when the drive motor M1 is rotated in the reverse direction with the moving panel P housed in the first housing part 3, the moving panels P in the first housing part 3 move toward the main rail 1 all at once, and the head moves. The panel P transfers to the main rail 1, and at the same time, the third limit switch L3 provided on the inner surface of the main rail 1 operates to stop the driving motor M1. With the transition to the main rail 1, the chain sprocket 34 of the moving panel P meshes with the fixed chain 22, and the self-propelled motor M2 rotates by receiving power supply from the trolley wire 26 ', and the moving panel P moves. Runs along the main rail 1 in the direction of arrow B.

In this case, each current collector 37 is connected to the end 2 of the trolley wire 26.
Since the chain sprocket 34 is biased in the direction of 6 ', the self-propelled motor M2 is energized before the chain sprocket 34 meshes with the fixed chain 22, and the chain sprocket 34 rotates and meshes with the fixed chain 22. The chain sprocket 34 to the fixed chain 22
Meshes smoothly.

Then, when the leading movement panel extended to the main rail 1 is separated from the intersection with the first storage portion 3 to some extent, the fourth limit switch L4 provided in the middle of the main rail 1 senses this, The drive motor M1 is re-driven to feed the next moving panel P toward the main rail 1.
By repeating this cycle, the moving panels P stored in the first storage portion 3 are sequentially extended to the main rail 1 (in this extended state, the trolley wire 26 is constantly energized).

The stopper 51 is held in the retracted state while the moving panel P is being drawn in and out between the first storage section 3 and the main rail 1, and the movable panel P is held in the first storage section 3
When the storage is completed, the operation of the first control device 20 is stopped, and as described below, the second control device 20 'which operates in exactly the same manner as the first storage / conveyance device 10 operates and the stopper 5
In cooperation with 1, the moving panel P is moved into and out of the second storage section 3 '.

That is, when the first storage portion 3 is full, the stopper 51
When the moving panel P travels toward the end of the main rail 1 in that state, the moving panel P is stopped by the stopper 51 at the intersection with the second storage section 3 '. At the same time, the stop switch L5 is actuated to turn off the power supply to the terminal end 26 'of the trolley wire 26, the self-propelled motor M2 is stopped, and the subsequent moving panel P is moved forward of the second storage 3'. Then, after a slight time lag, the drive motor M1 rotates in the forward direction, and the moving panel P stopped by the stopper 51 is fed into the second storage section 3.

When the movable panel P enters the second storage portion 3'by a certain size, the second limit switch L2 'is activated to stop the rotation of the drive motor M1 and the terminal portion 26' of the trolley wire is energized. Then, the next moving panel P waiting on the front side of the second storage section 3'runs and is fed into the second storage section 3'by the same operation as described above.

The stop switch L5 is provided for each moving panel P instead of being provided on the stopper 51.
It may be related to stop the rotation of the self-propelled motor M2 when 5 comes into contact with the stopper 51, which eliminates the need to use a separate power source for the terminal end 26 'of the trolley wire. 1 limit switch L1 is also unnecessary).

The feeding control from the second storage section 3'is exactly the same as the feeding control from the first storage section 3, and is automatically and sequentially fed out by the action of the third limit switch L3 'and the fourth limit switch LL4'. .

Reference numeral 56 shown in FIG. 1 denotes both the storage unit control devices 20,
A general control device for automatically controlling the operation of 20 'and the operation of stopper 51 is shown. This general control device 56
Includes a first control switch S1 for controlling the rotation of the control motor M3 in the stopping means 50 and a second control switch S2 for selectively operating both storage unit control devices 20, 20 '. , 6th to 9th limit switches L for detecting storage states in both storage sections 3 and 3 '.
6, L7, L8, and L9, which operate as follows.

That is, when both storage parts 3 and 3'are empty, the eighth and ninth limit switches L8 and L9 detect this and hold the stopper 51 in the retracted position, and only the first storage part control device 20. The movable panels P that have been operated and have traveled on the main rail 1 are sequentially fed into the first storage section 3.
Then, when the first storage section 3 becomes full, the sixth limit switch L6 operates to input to both control switches S1 and S2, whereby the control motor M3 rotates forward and the stopper 51 moves forward, The storage part control device 20 is powered off, and the second storage part control device 20 'is powered on.
Subsequent moving panels P are sequentially stored in the second storage section 3.

Then, when the moving panel P is completely stored in the second storage portion 3, the seventh limit switch L7 is actuated and input to S1, the control motor M3 rotates in the reverse direction, and the stopper 51 retracts. This completes the storage work.

On the other hand, when the movable panel P stored in both storage units 3 and 3'is unwound, the second storage unit 3'is moved in the reverse order.
When the second storage portion 3'is emptied, the ninth limit switch L9 detects this and is input to S2, the operation of the second storage portion control device 20 'is stopped, and the first storage portion is stopped. When the power to the control unit 20 is turned on, the first
The moving panels P stored in the storage section 3 are sequentially drawn out.

It should be noted that the moving panel Pn finally fed out from the first storage section 3 is configured such that the lateral width thereof expands and contracts, so that the final panel P of the moving panel Pn is partitioned by the moving panels P, P ,. The side end surface may be closely attached to the wall surface of the chamber.

Further, as in the embodiment, it is also possible to manually operate the longitudinal movement operation of the stopper 51 and both storage / conveyance devices 10 and 10 'without providing the general control device 56 and the storage unit control devices 20 and 20'. good.

In the above embodiment, two storages are arranged side by side,
It goes without saying that the present invention can be applied to a case where three or more storage units are arranged side by side, and in that case also, by providing the control device as in the above-mentioned embodiment, the moving panel can be put into and taken out from each storage unit. Can be done automatically.
