Description

Detailed Description of the Invention [Industrial Field of Application] The present invention consists of a plurality of movable shelves arranged closely, leaving one space that should be used as a passage for handling work, and the movable shelves can be moved as needed during the time of loading and unloading goods. This invention relates to an unfolding type electric movable shelf device that moves the movable shelves to form a passage for storing and discharging between desired shelves, and moves each movable shelf to a predetermined unfolded position when not in use.

[Prior art] In order to be able to arrange a large number of movable shelves in a narrow space, the space for the teller work formed between the shelves is left for one aisle, and the other movable shelves are spaced apart. Move these movable shelves by operating the aisle selection switch corresponding to each aisle to form a working aisle between the desired shelves and perform the retrieval work. 2. Description of the Related Art For purposes such as improving ventilation between each shelf, movable shelf devices have been conventionally provided that move movable shelves to a predetermined spread position so as to provide an interval between each shelf.

For example, there is an electric movable shelf device disclosed in Japanese Patent Application Laid-Open No. 198510/1993 filed by the applicant of the present invention.

This electric movable shelf device has a right travel limit timer and a left travel limit timer that control the motor by setting the travel time for right travel and left travel for each movable shelf, and it can be used for one work. When the passage moves from the open state to the unfolded position, the unfolding command means operates, and each travel limit timer in the corresponding movement direction is activated from the time when each movable shelf starts toward its respective unfolded position. was activated, and after the set time of each timer had elapsed, each movable shelf was configured to stop individually and reach its respective unfolded position.

[Problems to be Solved by the Invention] By the way, in the conventional electric movable shelf device, two travel limit timers are required for one travel motor, one for rightward movement and one for leftward movement, which reduces the number of parts. There was a problem that the number of circuits increased and the control circuit became complicated.

Also, even if you only want to change the spacing between one shelf for a fixed spreading position of movable shelves,
The conventional device has a problem in that it is necessary to readjust the set values of the timers for all the movable shelves, which is inconvenient in handling.

The present invention solves each of the above-mentioned conventional problems, reduces the number of parts, simplifies the control device, and makes it easy to adjust the timer set value. The purpose is to provide equipment.

[Means for Solving the Problems] The present invention provides movable shelves each equipped with a reversible motor for traveling in a compartment divided by fixed shelves or side walls, each having an extra space equivalent to one working passage. The movable shelves are moved by operating a passage selection switch to select a passage, and a working passage is formed between the shelves where articles are to be stored, and when the storing work is finished, the formed passage is reset. The control circuit is operated to release the control circuit to form the next required passage, and when the forming passage is not used,
In the spread-out electric movable shelf device, which forms a spread space at a specified position between the shelves, means for detecting a path to be formed by a path selection operation of the path selection switch, and after a reset operation of the formation path. An opening command means is prepared, an opening space formation timer for setting the opening width of opening spaces for each of the shelves, and opening positions for scattering the extra space between the shelves where the opening spaces are to be formed. and an opening control circuit for moving and stopping the movable shelf, and the opening control circuit operates when the working passage is formed and there is a command signal from the opening command means after the forming passage is reset. Then, each of the movable shelves unfolds all at once in the direction in which the forming passage closes, and at the time of the unfolding transition, each of the movable shelves corresponding to the expansion space formed in the expansion transition direction sequentially from the expansion space side at the rearmost end The spread space formation timer is
At the end of each time limit set in each spread space formation timer, the spread space is sequentially started, and within the set time limit of each spread space formation timer, the spread space is started in order to form the spread space between the shelves. The movable shelf on one side in the unfolding transition direction facing the opening transition direction moves, and at the end of the time period of the opening space formation timer, the moving shelves facing the opening space in the transition stop respectively at the unfolding position. The above-mentioned problem was solved by adopting a means of configuring the system to do so.

[Function] According to the present invention having the above-described configuration, in order to form a passage for the handling operation between the desired shelves at the time of article loading and unloading, by selection operation of a predetermined passage selection switch,
To automatically move a movable shelf to form a working passage and carry out the cashing and discharging work.

When the above-mentioned discharging operation is completed, after the forming passage is reset, when there is a command signal from the spreading command means, the spreading control circuit is activated, and the movable shelves are all moved toward the predetermined spreading position. take off.

At the time of the unfolding transition of each movable shelf, for each movable shelf group moving in the right direction and the left direction, the unfolding space formation timer corresponding to the unfolding space at the rear end that opens first during the simultaneous start starts operating, and the timer for forming the unfolding space starts operating. When the set operating time of the timer has elapsed, the last movable shelf of each of the movable shelf groups facing the spread space first stops, and at the time when the last movable shelf stops, the movable shelf stops. An expansion space formation timer corresponding to the expansion space between each of the last movable shelves and the adjacent movable shelf that continues to advance starts to operate, and when the set operating time of the timer has elapsed, the timer for forming the expansion space starts to operate. The adjacent movable shelf stops.

Similarly, in each movable shelf group, each expansion space formation timer corresponding to each expansion space is sequentially operated and timed up from the last shelf side,
Each of the movable shelves is sequentially stopped at an inter-shelf interval corresponding to the set operating time of each of the timers.

At the end of the set operating time of each unfolding space forming timer, each of the movable shelves stops at a predetermined unfolding position.

This is a flowchart showing path selection formation for moving the shelf to a state in which a shelf is formed, and will be explained with reference to the circuit diagrams of FIGS. 7 and 8.

First, in order to open the space 3 as a passage for teller work, the passage selection switch PB ₃ is operated 21 to operate the passage selection relay c ₃ and its break contact opens, and when the passage selection is completed, the passage is opened. Formation relay so operates 23 and its make contact closes.

Then, the right travel relays F ₃ and F ₄ operate 24, the reversible motors M ₃ and M ₄ rotate clockwise, and the movable shelves D and E travel to the right 25.

Further, when the movable shelves D and E move to the right 25, the separation detection switch LS ₅ comes into contact with the fixed shelf F, and with the separation detection switch LS ₄ in contact with the movable shelf E, the separation detection switch LS ₅ is activated. 26 then right running relay F ₃ , F ₄
returns 27, the reversible motors M ₃ and M ₄ stop, and the movable shelves D and E stop traveling 28.

When the movable shelves D and E are stopped 28, the space 3 is opened to form a passage for the teller work, and the teller work becomes possible, and the control circuit is automatically locked 29.
Since 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, a reset operation 30 of the passage selection switch PB ₃ is performed.
If the control circuit is reset 31 and there is still a teller work in another teller work passage 32,
By the selection operation 21 of the new passage selection switch, the related movable shelves are moved through the same operation sequence as described above, and the desired passage for the teller operation is selectively formed.

Further, if the passage selection is canceled by the reset 31 of the control circuit 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 this spreading command means exists in a spread space in which the passage width of the above-mentioned forming passage is divided into arbitrary intervals, and is spread out at the spread position. This is a command signal to move each movable shelf.

That is, this spreading command means is activated by a signal 33 of a reset operation of one of the path selection switches after the resetting operation of the forming 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 after the reset operation, and 36 based on a dedicated spreading command button to activate the spreading.
It consists of

Next, the operation of forming the spreading space will be explained, and in particular, the case where each movable shelf is moved and stopped at the evenly spread position shown in Fig. 2 will be explained.
This will be explained with reference to the circuit diagram of the spread space forming timer shown in the figure.

The setting time of each expansion space formation timer T ₁ to _{T 5} in FIG. 6 is the transition time of each movable shelf B, C, D, and E necessary to form the expansion space formation width La shown in FIG. 2. is set.

That is, when the movable shelves move from the state shown in FIG. 1 to the evenly spread position shown in FIG. - E start all at once, and the movable shelves B are moved at the elapse of time of spreading space formation timers T 1 and T 5 that set the formation width La of the spreading spaces ₁ and ₅ at the rear end facing each fixed shelf A and F. , E are stopped, and the expansion space formation timers T ₂ and T _{4 that set the formation width of the expansion spaces 2 and 4} to be formed next are started.
The movable shelves C and D are designed to stop when the set time of the timer has elapsed.

Therefore, if the setting time of the expansion space formation timer T ₁ to _{T 5} is long, the transition time of the movable shelf to form the expansion space becomes longer, the space at the time of formation becomes wider, and the setting time becomes zero. If this happens, the spread space will not open, and the spaces between the shelves will remain densely packed.

Therefore, by adjusting the setting time of the spreading space formation timers T ₁ to _{T 5} , the spreading space forming width can be set to any desired spreading space forming width to any shelf within the range of dividing and scattering the aisle width during the teller work. can be formed between.

In this way, the spread space formation timer is set on each movable shelf, and the space 3 shown in Fig. 1 is moved from the state where it is opened and becomes a passage for the teller work to the evenly spread position shown in Fig. 2 and stopped. This will be explained with reference to the flowchart of FIG. 11 for opening and stopping.

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 path may be memorized, or it may be detected using a separation detection switch or the like.

When a formation passage is detected, the passage selection relay _c3 of the passage concerned operates 42, and the spread formation relay SC operates 4.

In the opening space formation timer circuit of FIG. 6, the break contact _c3 opens, the make contact sc closes, and the opening space formation timers _T1 , _T5 start 44,
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 make contact sc of the spread formation relay is closed, and the movable shelves B and C are connected to the right traveling relay _F1. , F ₂ , and movable shelves D and E, the operating circuits of the left running relays R ₃ and R ₄ are selected, and the separation detection switch LS ₃ is in the ON state (see Figure ₁ ). Left running relay R ₃
operates and closes its make contacts f ₂ and r ₃ .

In addition, by closing the same make contacts f ₂ and r ₃ , the right running relay F ₁ and the left running relay R ₄ also operate 4.

_R3 . When the make contacts f ₁ , f ₂ , r ₃ , r ₄ close in the motor drive circuit shown in FIG. 8 due to the operation of R ₄ , the reversible motors M ₁ and M ₂ rotate clockwise, and the reversible motors
M ₃ and M ₄ rotate to the left.

Therefore, movable shelves B and C run to the right, and movable shelves D and
E starts driving to the left 47.

In Fig. 6, the spread space formation timers T ₁ and T ₅
has started, so when the set time elapses (time-up) 48, 49, the opening space forming timer also closes the contacts _t1 , _t5 , and the opening space forming timers _T2 , _T4 start 50, 51.

On the other hand, when the set time of the expansion space formation timers T ₁ and T ₅ elapses (time up), the contacts t ₁ and t ₅ of the expansion _space formation timer in FIG. ₄ is restored 52, 53,
Open the make contacts f ₁ and r ₄ in Fig. 8 and connect the reversible motor.
The power to M ₁ and M ₄ is cut off, and the movable shelves B and E are stopped 54 and 55.

In addition, the movable shelves C and D56 that are running are set to elapse (time up) of the spread space forming timers T ₂ and T ₄ that are started at the same time as the movable shelves B and E stop.
At steps 57 and 58, contacts t ₂ and _{t 4 of} the spread space formation timer shown in FIG. f ₂ and r ₃ are opened, the power to the reversible motors M ₂ and M ₃ is cut off, and the movable shelves C and D are stopped 61 and 62.
do.

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