Description

Detailed Description of the Invention The present invention maintains passages formed between movable shelves in a multi-aisle controlled movable shelf for safe use and forms new passages between other shelves. Relating to a device for releasing maintenance.

When automatically controlling a large number of movable shelves, it is important to ensure the safety of the shelf users and operators, but if the automatic control operation becomes complicated for this purpose, operability will decrease and operational errors may occur. As a result, shelf usage efficiency decreases.

The present invention provides, in movable shelf control, a regular middle aisle and a half aisle formed by stopping shelf movement before the regular middle aisle is completed, without complicating the operation of the movable shelf control. To provide a device which maintains any passage in a state where it is not closed and can easily release the maintenance of the passage by the same operation regardless of the passage state.

First, the multi-aisle control movable shelving device according to the present invention will be explained based on FIG. The shelf at the end is a fixed shelf 1a, and the other shelf group 1 parallel to the fixed shelf 1a
are movable shelves 1b that can each move on their own along guide rails 2 perpendicular to the shelf storage surface, and at the end of the guide rail 2 on the opposite side from where the fixed shelf 1a is provided, there is a regular medium passage 3
Stoppers 4 are provided at at least two locations with an interval between them.

The movable shelf 1b is equipped with a motor 5 for self-propulsion, the output shaft of the motor 5 is connected to a drive wheel 6, and the motor 5 can rotate in either forward or reverse directions.

The fixed shelf 1a and the movable shelf 1b... are equipped with a passage closing detection microswitch XS that detects that the passage 3 between the shelves is closed;
Safety bar operation detection micro switch ZS that detects whether a foreign object is inserted into the passage 3 when the passage 3 is closed.
When forming aisle 3, there is an aisle width detection micro-sinch YS that detects that the interval between shelves has become the regular aisle width.
It is equipped with

Note that the final movable shelf ib/ on the opposite side of the fixed shelf 1a is not equipped with the passage width detection micro-sinch YS.

Furthermore, the fixed shelves 1a and the movable shelves 1b... are equipped with a passage forming pushbutton switch OB that is operated when forming a passage between adjacent shelves, and the passage forming pushbutton switch OB is used to close the formed passage. This pushbutton switch O
Along with B, there is provided a lock release push button switch EB for making the lock passage a passage that can be closed when forming a new passage between other shelves, that is, a free passage.

A lock passage indicator lamp L1 and an emergency indicator lamp L2 are provided above both pushbutton switches OB and EB.

In addition, each column 1a, 1b... is a push button switch O
B, EB, micro-sinches It is.

FIG. 2 shows the basic circuit of the above-mentioned control device, and shows other intermediate parts excluding the fixed shelf 1a, the first stage movable shelf 1b'' adjacent to the fixed shelf 1a, and the last stage movable shelf 1b'. mobile shelf 1
b (all constructed from the basic circuit shown in FIG. 2).

□ (However, the fixed shelf 1a and the first and final stage movable shelves 1b'' and 1b' are basically the same as the circuit in FIG. 2, with unnecessary control circuits removed.

Next, the timing and purpose of the operation of the group of relays shown in FIG. 2 will be explained.

Relay A is activated when the passage forming pushbutton switch OB is operated, and when the passage width detection micro-sinch YS is closed and activated, relay Y is activated, or the timer T is set to start timing at the same time as relay A is activated. When the time elapses, the relay A is restored and is a passage forming control device.

Relay B operates at the same time as relay A, continues to operate even after relay A is restored, and locks the passage in the passage forming layer, and also operates relay C by operating the lock release push button switch EB.
When activated, the relay B is the first road lock control device.

Relay C is activated by operating the lock release pushbutton switch EB only when relay D is activated, and is restored at the same time as relay D is restored, and relay C is a lock path release device.

Relay D is activated when relay A is restored, or when pushbutton switch EB is operated while relay A is in operation, and is restored by activation of relay C. Relay D converts the passage into a locked passage when forming a half passage. This is a second passage lock control device for

Note that if the pushbutton switch EB is activated while relay A is operating, that is, while the passageway is being formed, relay A will be restored and passageway formation will stop midway, and the passageway formed at that time will not have the normal passageway width. It becomes a half passage.

Relay E resumes operation at the same time as relay B, and relay E
is for aisle lighting.

In addition, the lock passage indicator lamp L is the same as this relay E.
1 also flashes.

Relays F and R are the same as relays A and B.

X is the main element, and is controlled according to the states of each of its relays A, B, and X. Relay F is a self-propelled control device in the spreading direction, and relay R is a self-propelled control device in the focusing direction.

Note that the spreading direction is the direction of the stopper 4, and the focusing direction is the direction of the fixed shelf 1a.

Relay F operates at the same time as a magnet relay provided in parallel with relay F, and the magnet relay controls motor 5 to run on its own in the unfolding direction.

The relay R operates at the same time as a magnet relay casing provided in parallel with the relay R, and the magnet relay casing controls the motor 5 to self-propel in the focusing direction.

Relays X, Y, and Z are microswitches XS.

This is an auxiliary control relay whose operation is restored by ys and zs.

In addition, relays G and H are common to each column 1a, Ib..., and relay G is activated when any relay Z in each column ia, lb... is operated, and each column 1a
, Ib, . . . to stop the moving shelf, relay H is also operated as a linker by relay Z, and the emergency stop lamp L2 of the shelf on which relay Z has been activated is displayed blinking.

In Figure 2, the contact groups of each relay are indicated by lowercase letters stamped on the relay, and among the contacts, the contacts surrounded by dotted lines indicate the contacts of the relays in the control circuit of the adjacent shelf. The direction of the shelf is the open side of the dotted line.

Also, if Figure 2 is generally expressed as a shelf number m, the right side is the shelf in the convergence direction, the shelf number m-I, the contact code of that shelf is affixed with ('), and the left side is the shelf in the spreading direction. The number m+1 shelf is indicated by adding ('') to the contact code of that shelf.

Next, the first and second passage lock control devices according to the present invention will be described in detail.

When the relay B related to the first passage lock control device is activated, the shelf on which the relay B is installed (
mth) and the adjacent shelf in the left side spread direction (m+1st)
Lock the passage formed between the

That is, to close the passage between the mth and m+1th shelves, the mth shelf must move in the spreading direction, or
The +1st shelf must move in the focusing direction.

Therefore, relay B provides a normally closed contact b1 that can prohibit the operation of the circuit in the self-running control circuit in the spreading direction of the shelf m, and also connects it to the free-running control circuit in the focusing direction of the m+1th shelf. , a normally closed contact b' that can inhibit the operation of the circuit! will be established.

Therefore, when relay B is activated, both self-running control circuits of shelf m and shelf m+1 are connected to contact b1. At b'2, the operation is prohibited and the passage becomes a lock passage.

Relay B is the contact point OB of the passage forming pushbutton switch OB.
1. It operates via the normally open contact a1 of relay A, which is activated by closing OB2, and is self-held by a self-holding contact b3 provided in parallel with the contact a1.

The self-holding contact b3 of the relay B has a normally closed contact c1 of the relay C in series with the contact b3, and the contact c1 restores the relay B by activating the relay C, thereby
Activation of relay C releases the lock passage controlled by activation of relay B.

Relay C includes a normally open contact b4 of relay B, a normally open contact d1 of relay D, and a self-holding contact c2 in series, and when relay D is operating and closes contact d1, Normally open contact E of lock release pushbutton switch FB
It operates when B1 is closed.

That is, the relay D prohibits the operation of the lock release device by the relay C, and prevents the lock passage from being released, thereby forming a second lock passage control device.

Relay D is activated by the normally closed contact a2 of relay A, which is restored when a normal medium passage is formed, and during the period when relay A is activated, relay C is prohibited from operating, and the 1 lock passage control device is prohibited from being released, and relay A is
This ban will be lifted once the country is restored.

When the lock release pushbutton switch EB is operated while the relay A is operating, that is, while the passage is being formed, the normally closed contact EB2 of the switch EB opens and restores the relay A.
The running of the shelf is stopped via the normally open contacts a'3j and a4.

When the operation of the pushbutton switch EB is completed, the normally closed contact E
B2 is closed and normally closed contact a2 of relay A has already been restored.
Activates relay D via.

In addition, while relay A is operating, even if the lock release pushbutton switch EB is operated, the second passage locking device of relay D will not release the first passage locking device of relay B, and the relay A will not be released. Only the passage formation control device is restored, and the half passage formed at that time, which is narrower than normal, becomes a lock passage.

After relay D is activated, if push button switch EB is operated again, relay C is activated and the lock passage is released.

Note that the normally open contact a2 of the relay D, which is parallel to the contact EB2, is
Self-holding contact for timing.

Further, in order to make a free passage which has already been formed and which has been unlocked once again into a locked passage, the passage forming pushbutton switch OB is operated.

In this case, the passage width detection microsinch YS of the passage to be locked is operating, activating relay Y, and the operation of relay A is prohibited via the normally closed contact y1 of relay Y, and the As a result, relays B and D operate simultaneously, making the passage a lock passage.

Further, when the half passage is a free passage, in order to make the free passage a locked passage, the passage forming pushbutton switch OB is operated in the same manner as described above.

In the case of this half aisle, relay Y is not activated, so the self-propelled control device is set to 1 to make the shelf a regular middle aisle.
Once activated, if control is continued, a lock passage of the normal medium passage is formed.

However, when a lock passage which remains a half passage is required, the push button switch EB is operated directly under the operation of the push button switch OB.

In this case, it is the same as when pushbutton switch EB is operated while relay A is operating, and the half passage becomes a lock passage.

As described above, the present invention reduces the number of switches to be operated to a minimum of two, and performs passage forming operation, passage forming stopping operation, maintaining operation of the formed regular medium passage, maintaining operation of the formed half passage, and The release operation of the maintained lock passage does not require any complicated combination operation, and can be done by simply operating a switch according to the situation, which improves the safety of movable shelf control.
Improved operability can be measured.
