When there is a command signal from the expansion command means, the expansion control circuit operates, and the movable shelves simultaneously expand and move in the direction in which the forming passage closes. , the respective expansion space formation timers corresponding to the expansion spaces that are sequentially formed in the expansion transition direction are successively started at the end of the time limit set for each expansion space formation timer, and the respective expansion space formation Within the set time limit of the timer, in order to form the spread space between the shelves,
The movable shelves on one side in the unfolding transition direction facing the spread space are moved, and at the end of the time period of the spread space formation timer, the movable shelves facing the spread space and in the process of transition are respectively moved. The above-mentioned problem was solved by adopting a means of configuring the device to stop at the unfolded position.

[Function] According to the present invention having the above-described configuration, in order to form a passage between desired shelves for storing and storing goods, the movable shelves are automatically moved by selection operation of a predetermined passage selection switch. A working passage is formed to carry out the cashing and discharging work.

Then, at the end of the dispensing operation, when there is a command signal from the spreading command means after the resetting operation of the forming passage,

First, in order to open the space 3 as a passage for teller work, by performing a selection operation 21 on the passage selection switch PB3, the passage selection relay C3 operates 22 and its break contact opens, and upon completion of passage selection, the passage forming relay is activated. S.O.
operates 23 and its make contact closes.

Then, the right travel relays F3 and F4 operate 24, the reversible motors M3 and M4 rotate clockwise, and the movable shelves D and E travel to the right 25.

stops running 28.

When the movable shelf DE is stopped 28, the space 3 is opened and a passage for the teller work is formed, and the teller work becomes possible.
Since the control circuit is automatically locked 29 and the state of the teller work passage shown in FIG. 1 is maintained, the safety of the teller work in the teller work passage is ensured.

When the teller work using the teller work passage is finished and the teller work passage in the space 3 is no longer needed, the control circuit is reset 31 by the reset operation 30 of the passage selection switch PB3, and the other teller work passages are then used. When there is a teller work at 32, the related movable shelves are moved through the same operation sequence as described above by the selection operation 21 of the new passage selection switch, and the desired passage for the teller work is selected and formed. Become.

Further, if the passage selection is canceled by the operation of the control circuit reset 31 and there is no selection operation of the next passage selection switch, the flowchart shifts to the unfolding command means shown in FIG.

FIG. 10 is a flowchart showing the spreading command means in the device of the present invention, and each time the spreading command means exists a spreading space in which the passage width of the above-mentioned forming passage is divided into arbitrary intervals, and each time 9 This is a command signal to move the moving shelf.

That is, this spreading command means is activated by a signal 33 of a reset operation of any of the passage selection switches after the resetting operation of the formation passage, and by a signal activated after a certain period of time has elapsed by a timer circuit that is started after the resetting operation. 34, 35 based on an output signal activated at a set time by a daily or weekly time switch circuit that starts after the reset operation, and 3 based on a dedicated spreading command button that activates spreading.
It consists of 6.

Next, we will explain the operation of forming the spread space, but in particular, move each movable shelf to the evenly spread position shown in Figure 2.
The case of stopping will be explained with reference to the circuit diagram of the spread space forming timer shown in FIG.

The setting time of each expansion space formation timer KING, ~T, in FIG. 6 is the transition time of each movable shelf B-C-D-E necessary to form the expansion space formation width la shown in FIG. is set.

In other words, when each movable shelf moves from the state shown in FIG. 1 to the evenly spread 0 position shown in FIG. B-E start all at once, and the movable shelves are opened at the elapse of time T1 and T5 of the spread-out space formation timer that sets the formation width 1-a of spread-out spaces 1 and 5 at the rear end facing each fixed shelf A-F. B-E stops, and then the spread spaces 2 and 4 are formed.
Spread space formation timers T2 and T4 that set the formation width of
is started, and the movable shelves CD are stopped when the set time of the timer has elapsed.

Therefore, if the setting time of the expansion space formation timer T1 to T5 is long, the transition time of the movable shelf to form the expansion space will be longer and the space at the time of formation will be wider. The spread space does not open, and each shelf remains densely packed.

Therefore, by adjusting the setting time of the spreading space formation timer T1-T5, the spreading space forming width can be set to any desired width between each shelf within the range of dividing and scattering the aisle width during the teller operation. It can be formed into

In this way, the spreading space formation timer is set on each movable shelf, and the operation moves from the state where the space 3 shown in Fig. 1 is opened and becomes a passage for cashier work to the evenly spread position shown in Fig. 2 and stops. will be explained with reference to the flowchart of FIG. 11 showing the unfolding transition/stop.

The formation passage detection means is actuated 41 by the command signal from the spreading command means, and detects the formation passage in the space 3.

In this detection method, the formed passage may be memorized, or may be detected using a contact/separation detection switch or the like.

When a formed passage is detected, passage selection relay C3 for the passage
operates 42, and the spread-forming relay SC operates 43.

In the opening space formation timer circuit of FIG. 6, the break contact C3 is opened, the make contact SC is closed, and the opening space formation timers T1 and T5 are started 44 and 45.

On the other hand, in the movable shelf movement selection circuit diagram of FIG. 7, the break contact C3 of the passage selection relay is opened, the meter contact SC of the spread formation relay is closed, and the movable shelf B-C is connected to the right traveling relay F,・For F2 and movable shelf D-E, the operating circuit of left running relay Ra-R4 is selected, and separation detection switch LS3 is in the ON state (see Figure 1).Right running relay F2 and left running relay R3 are Work,
Close the make contacts f2 and F3.

Also, by closing the same make contacts f2 and F3,
Right running relay F and left running relay R4 also operate 46.

Said right running relay F1 ・``2 and left running relay R3
・When the make contacts f1, f2, F3, and F4 close in the motor drive circuit shown in FIG. 8 due to the operation of R4, the reversible motor M1 and M2 rotate clockwise, and the reversible motor M3
・M4 rotates to the left.

Therefore, the movable shelves B-C start running to the right, and the movable shelves D and F start running to the left (47).

In FIG. 6, the spread space forming timer T1T5 has started, so the set time has elapsed (time up>48.
At 49, contacts t1 and ↑5 of the expansion space formation timer are closed, and the expansion space formation timer 3 T2 and T4 are started 50 and 51.

On the other hand, when the set time of the expansion space formation timers T1 and T5 elapses (time up), the contacts t1 and t5 of the expansion space formation timer shown in FIG. 7 open, and the operating right travel relay F1 and
The left travel relay R4 is returned 52 and 53, the meter contacts f1 and F4 shown in FIG.

In addition, the movable shelf C-D56 that is running is operated by the spread space forming timer T2, which is started at the same time as the movable shelves B and E stop.
When the set time of T4 has elapsed (time up> 57, 58), contacts t2 and t4 of the spread space formation timer shown in Fig. Open the make contacts f2 and F3 in the figure, cut off the power to the reversible motors M2 and M3, and
-D stops 61 and 62.

In this way, when each movable shelf stops, the unfolding control circuit is reset 63, and the space 1, as shown in FIG.
2, 3, 4, and 5 are evenly spread out.

As described above with respect to the embodiments, the present invention is an unfolding type electric movable shelf device in which each movable shelf is configured to be able to be spread out and packed together to increase the storage density in a narrow space, while also making the loading and unloading work quick and easy.
