DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelving apparatus, and more particularly to a shelving apparatus having a safety device for securing a clearance for a passage between adjacent shelves that does not pinch a human body.

[0002]

2. Description of the Related Art As one of storage shelves used for archives and the like, a fixed storage shelves fixedly arranged at the end of a rail on a floor in a room, and a large number of shelves movable on the laid rails. There are storage shelves in which shelves are combined. The shelves are provided with a large number of shelves with wheels on the rails laid on the floor as described above, and when putting in and out articles, the desired shelves or the shelves adjacent to the shelves are moved along the rails. By moving, a clearance for a passage can be provided on the front surface of a desired storage shelf.

[0003] A storage rack device moves a desired storage rack or a storage rack adjacent thereto only when an article is taken in and out, and provides a gap as a passage between adjacent storage racks.
At other times, the shelves can be kept in close contact with each other, so compared to a case where many shelves are fixed and installed indoors, the advantage that the space when articles are not taken in and out can be widely used. There is.

In order to move the shelves, a manual handle is provided on the side wall of the shelves, and a mechanism for interlocking the handles and wheels via a transmission member such as a chain or a belt is provided. A configuration in which a motor serving as a drive source is mounted on a storage rack and wheels are rotated by a reduction mechanism disposed between the motor and the wheels is used. When a motor is used, an operation panel having a switch for instructing the rotation direction of the motor in accordance with the direction of movement of the shelf is provided on the side wall of the shelf, so that the operator can instruct the movement operation. There are things that are.

[0005] By the way, in the storage shelves, when a gap for passage is provided between adjacent storage shelves, it is necessary to prevent the adjacent storage shelves from approaching each other through the gap and to secure a gap. In some cases, one of storage shelves opposed to each other with a gap therebetween is provided with a locking bar that can protrude from the other storage shelves.

The locking bar is a bar provided so as to be swingable on one surface in the moving direction of the adjacent storage shelf, and the length from the swing base end to the swing end can secure the gap. Set to length. As a result, the locking bar extends from the normally raised state to the adjacent storage shelf by falling down, and when the adjacent storage shelf approaches, the swinging end abuts on the storage shelf. Thereby, a gap as a passage can be secured. By providing such a locking bar, even if an operator is in the passage, it is possible to safely carry out the work of taking in and out of the article.

Conventionally, the operation of tilting the locking bar to secure a clearance for a passage is left to the operator at present.

[0008]

However, the storage shelves provided with the above-described locking bars have the following problems. Since the operation of tilting the locking bar and providing the clearance for the passage relies on manual labor, if the operator neglects the operation, the other operator may be in the clearance for the passage even though there is an operator in the clearance for the passage. If the shelves are moved without being noticed, the passage is narrowed, and the operator in the passage clearance may not be able to escape.

In particular, in recent years, there is an earthquake as a case where such unexpected movement occurs. In other words, in the case of an earthquake,
Even if the wheels are locked and braking is applied, the wheels can easily slide on the rails due to the extremely smooth surfaces of the wheels and the rails. In addition, when the shelves slide in the event of an earthquake, the shelves collide with an end stopper provided at the end of the rail due to the vibration during the earthquake, and due to the recoil, the shelves repel each other. There are cases.

[0010] If a person tries to push back the shelves once moved by the earthquake with human power, a large number of shelves start moving at the same time, so that the impact force becomes considerably large unlike the case of a single shelves. Although impossible, it is extremely dangerous for operators in the aisle. In addition, when an earthquake occurs, there is a great danger that an operator in the passage is prevented from escaping, in combination with the fact that humans can only stand up or cling to familiar objects. Such a dangerous state can be applied not only to a manual shelving device that moves by a handle, but also to an electric shelving device that uses a motor as a driving source for movement.

Accordingly, an object of the present invention is to provide a clearance as a passage automatically when an accidental movement occurs, particularly when an earthquake occurs, in view of the above-mentioned problems in the conventional shelves. It is an object of the present invention to provide a safety device for a shelving apparatus having a configuration capable of performing such operations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter , the present invention will be described in detail with reference to illustrated embodiments.

FIG. 1 is a side view of a storage rack device according to the present invention. In FIG. 1, a plurality of storage racks 2, 3, 4,... , 3
Table shelves are shown) are arranged side by side on rails 5 laid on the floor. 1, reference numeral A1, A2 is that illustrates the fixing storeroom shelves are fixedly disposed on the distal end of the rail 5.

[0018] Storage shelves 2, 3, 4, respectively incorporates a wheel driving motor 6, transmitted to the wheels 1 through the speed reduction mechanism and the endless transmission member rotational force is not shown from the wheel driving motor 6 It is supposed to be. In this case, a toothed belt or a chain is used as the endless transmission member. Although not shown, a clutch 21 for connecting and disconnecting the rotational force is provided in the rotational force transmission path from the wheel driving motor 6 to the wheel 1. This clutch is normally maintained in a contact state capable of transmitting rotational force, and
As will be described in detail later, when a predetermined seismic intensity is detected, a disconnection state in which the rotational force is not transmitted is set.

Among the storage shelves, movable storage shelves 2, 3,.
4 is provided with a safety device. The safety device is a device for preventing the storage shelves from being inadvertently moved and narrowing the passage gap when a clearance for a passage is formed between adjacent storage shelves. Hereinafter, the configuration will be described.

The safety device includes a lever member 7, lever operating means 8, and driving means 10. The lever member 7 is provided on at least one of the pillars located on both sides of the front surface orthogonal to the direction of movement of the shelf, among the pillars 11 located at the corners of the shelf.

In FIG. 2, the lever member 7 has a support shaft 12 inserted at the base end, and the support shaft 12 is rotatably supported by a channel-shaped bracket 13. The length of the lever member 7 is set to a length that can set a passage width such that a human body is not pinched between adjacent storage shelves.

The bracket 13 has its bottom surface fixed to the column 11, so that the lever member 7
Supported on the side. As a fixing method of the bracket 13,
Not only a general integration method such as welding, but also an attachment method using bolts or rivets is adopted.

The lever member 7, whose base end is supported by the column 11, can swing between an upright position parallel to the front surface of the storage shelves and a sideways position protruding forward from the storage shelves. When swinging to the attitude, a gap for a passage that does not pinch a human body can be formed between adjacent storage shelves.

The pivot end side of the lever member 7 and the support 11
The permanent magnet 1 which is a magnetic material for setting the lever member 7 to the raised position is located at a position facing each other on the surface of
4 and 15 are respectively attached.

In this embodiment, the lever actuating means 8 is constituted by a solenoid 16 which forms an electromagnetic member, and has a type in which a plunger 16A protrudes from the solenoid body when energized (hereinafter referred to as a push type). Used.

The amount of protrusion of the plunger 16A is
The distance between the magnets 4 and 15 at which the magnetic attraction is canceled is set to an amount that can be set between the magnets.

The driving means 10 pairs the storage shelves 2 , 3, and 4 with each other .
It includes a power supply control unit that the elephants, FIG. 3 is a block diagram for explaining the system configuration.

In FIG. 3, the driving means 10 controls the power supply.
On the input side of the unit, a backup power supply 10A for power failure arranged in an electric circuit from a commercial power supply, a seismic sensor 17, a lever member position detecting member 18, a passage detecting member 19, and a shelf moving switch 20 are respectively connected. ing. In FIG. 3,
Reference numeral 10B denotes a key switch serving as a power switch of the storage shelves. When the key switch 10B is turned on, power supply control to the drive motor 6 can be performed through an on / off operation of the shelf moving switch 20. It has become.

On the output side of the power supply control section of the driving means 10, a wheel driving motor 6 (see FIG. 1), a driving driver 100 for controlling the operation of the clutch 21, and a solenoid 16 as lever operating means are connected. ing.

The seismic sensor 17 uses a mercury-type acceleration detection switch and operates at a seismic intensity of 5 (100 to 200 gal). In this embodiment, the predetermined seismic intensity is assumed to be seismic intensity 5 as described above. However, the present invention is not limited to this, and it is intended for seismic intensity in which an inadvertent movement of a storage shelf occurs. Yes, it is possible to set the seismic intensity below.

As shown in FIG. 2, the lever member position detecting member 18 is composed of a microswitch provided on the column 11 opposite to the base end of the lever member 7, and the lever member 7 is turned sideways. When in the posture, a detection signal indicating that the vehicle is in the posture is output.

As shown in FIGS. 1 and 4, the passage detecting member 19 is rotatably supported by the ceiling among the cable support arms 23 which are bridged between the ceilings of adjacent storage shelves and are freely bendable. 4A and 4B. The limit switch is disposed in correspondence with the supporting portion, and as shown in FIG. 4, the cable supporting arm 23 is bent (see FIG. 4A) and extended (see FIG. 4B). ) Is a member that outputs a signal for detecting that a gap for a passage is formed by utilizing the change in the relative position between the support portion and the actuator 19A. The detection signal from the passage detection member 19 is
The signal is output when the cable support arm 23 is extended to such an extent that a gap for a passage can be formed.

The shelf moving switch 20 (see FIG. 1) is a switch with a self-holding function used when moving the storage shelves. In the case of this embodiment, two switches are provided according to the direction in which the shelves are to be moved. I have. When moving the shelves,
What is necessary is just to select and operate the shelf movement switch 20 corresponding to the direction to move. As a result, the power supply to the drive motor 6 is started, and the drive motor 6 starts rotating, and continues to rotate until the passage detecting member 19 detects that a gap for a passage is formed. It has been stopped.

The drive means 10 controls the normal movement of the shelves and automatically sets the lever member 7 to the sideways position. In particular, the lever member 7 is set to the sideways position. When an earthquake occurs in a state where there is no earthquake, when the seismic intensity is a predetermined seismic intensity, the operation of the lever operating means is controlled so that the lever member 7 is forcibly set to the sideways position. For this reason, when the predetermined seismic intensity is detected based on the signal from the seismic sensor 17, the driving unit 10 controls only when a gap for a passage is formed between the storage shelves based on the signal from the passage detecting member 19. Thus, power is supplied to the solenoid 16 constituting the lever operating means 8. Further, when the solenoid 16 is excited by supplying power to the solenoid 16, the lever member 7 is set to the sideways position. When the position is detected by the lever member position detection member 18, the wheel The power supply to the driving motor 6 is also stopped. When a predetermined seismic intensity is detected by the seismic sensor 17, the clutch 21 is set to the disengaged state.
As a result, the wheels 1 can be rolled in conjunction with the floor sway, and the sway in the direction along the rails 5 is minimized from being transmitted to the upper part of the storage shelf.

Since the present embodiment has the above configuration,
At the time of normal operation, that is, when the storage shelf is moved when the predetermined seismic intensity is not detected by the seismic sensor 17, the following procedure is adopted. First, the shelves that form the passage gap for carrying out the work are selected. In order to move a desired shelf, the shelf moving switch 20 of the driving means 10 is operated in accordance with a desired moving direction.

When the shelf moving switch 20 is operated, the driving means 10 rotates the driving motor 6 of the desired storage rack in accordance with the selected moving direction, and sets the clutch 21 to the contact state. As a result, the shelves to be moved moved from when the shelf movement switch 20 was operated to when the signal from the passage detecting member 19 was output, and the signal from the passage detecting member 19 was output. When the power supply to the drive motor 6 is stopped at the point in time, the drive is stopped in a state where a gap for a passage is formed.

When a clearance for a passage is formed between adjacent storage shelves, the operator manually sets the lever member 7 to the sideways position against the magnetic force between the permanent magnets 14 and 15 which are magnetic bodies. can do. When the lever member 7 is in the sideways position, the drive motor 6 is maintained in a stopped state via the drive means 10 by a signal from the lever member position detection member 18. This prevents the shelves from moving and prevents the passage gap from being closed.

On the other hand, when an earthquake occurs without moving the storage shelf and forming the clearance for the passage and setting the sideways posture of the lever member 7 by the operator,
In the following procedure, the lever member 7 is forcibly set to the sideways posture.

The procedure for moving the desired shelves to a position where a passage gap can be formed is the same as the procedure described above.
When a predetermined seismic intensity is detected by the seismic sensor 17 in a state where the passage gap is formed, the drive unit 10 stops supplying power to the drive motor 6 in response to a signal from the passage detection member 19. The clutch 21 is set to the disengaged state, and power is supplied to the solenoid 16 constituting the lever operating means 8. The operation by stopping the power supply to the driving motor 6 and setting the switching of the clutch 21 to the disconnected state is performed by the driving means 10
Is as described in the description of.

When power is supplied to the solenoid 16 constituting the lever operating means 8, the plunger 16A protrudes, and the lever member 7 protrudes. When the posture in which the plunger 16A protrudes is set by the operation control by the driving means 10, the lever member 7 is released from the attraction relationship due to the magnetic force between the permanent magnets 14 and 15, and moves from the upright posture to the sideways posture. Swings (see FIG. 2B).

When the lever member 7 swings to the sideways position, the lever member position detection member 18 instructs the drive means 10 to indicate that the lever member 7 is in the sideways position. Similarly to the above, the stop of the power supply to the drive motor 6 is maintained.

According to the present embodiment, even if the operator neglects to set the lever member 7 in the sideways posture, the lever member 7 is forcibly and automatically turned to the sideways posture when an earthquake occurs. Since the setting is made, an escape path for the operator who is working can be secured in the clearance for the passage.

In the above-described embodiment, the push type in which the solenoid 16 used as the electromagnetic member constituting the lever actuating means 8 pushes the plunger 16A and pushes the lever member 7 is used as it is. Can be used in the state shown in FIG.

In FIG. 5, a solenoid 160 constituting the lever actuating means 8 has a push rod 1 when energized.
The type in which 60A is drawn into the solenoid 160 is used. The plunger 160 </ b> A
Without being opposed to the lever member 7. In this configuration, in order to set the lever member 7 to the sideways position by exciting the solenoid 160, the moving stroke of the push rod 160A generated when the solenoid 160 is excited is used for pushing the lever member 7. A member is provided.

[0045] In FIG. 5, the push rod 160A of the solenoid 160, the proximal end of the actuating lever 161 as members for pushing pushing the lever member 7 is installed. The operating lever 161 is folded from the base end toward the side facing the lever member 7, and the folded distal end faces the lever member 7.

When the solenoid 160 is not excited, the plunger 160A protrudes from the operating lever 161 in a normal state, so that the pushing operation on the lever member 7 is not performed (see FIG. 5A). ).

On the other hand, when the solenoid 160 is excited through operation control by the driving means 10, the plunger 160
Since A is drawn into the body of the solenoid 160, the operating lever 161 can push the lever member 7 by pushing its tip toward the lever member 7, thereby setting the lever member 7 to the sideways position. (Figure 5
(B)).

When the lever member position detecting member 18 detects that the solenoid 160 is excited and the lever member 7 is set to the sideways position, the driving means 10 drives the lever member 7 in the same manner as in the above-described example. Power supply to the motor 6 is stopped.

As described above, the configuration for setting the sideways posture of the lever member 7 shown in FIGS.
0 of the plunger 16A, by 160A is protruded or retracted in the plunger itself, or since the operation pressing pushing lever member 7 by using an intermediate member such as the operating lever, that referred to as push-type collectively.

Next , as a type of the solenoid constituting the lever operating means 8, a type in which the plunger is pulled out into the solenoid main body (hereinafter referred to as a pull type) instead of protruding the plunger at the time of excitation is used. that describes an example to be set in place.

[0051] FIG. 6 is a modification of the case of using the solenoid shown in FIG. One end of an operating lever 165 is attached to a plunger 163A of a solenoid 163 that constitutes the lever operating means 8. Operating lever 165
Is swingably supported by a fulcrum shaft 165A supported by a bracket 164 provided for attaching the solenoid 163 to the column 11. The operating lever 165 having such a configuration has the other end opposite to the above-described one end with the fulcrum shaft 165A interposed therebetween, and is opposed to the lever member 7.

In this example, during normal times when the solenoid 163 is not excited, the lever member 7 is set to the upright position by the magnetic force generated between the permanent magnets of the column 11 ( see FIG. 6A).

When a predetermined seismic intensity is detected by the seismic sensor 17, power is supplied to the solenoid 163 via the driving means 10, and the solenoid 163 is excited. As a result, the plunger 163A is drawn into the main body of the solenoid 163, so that the operating lever 165 having one end attached to the plunger 163A swings, and the other end pushes the lever member 7 so that the lever member 7 is turned sideways. ( See FIG. 6B ).

When the lever member 7 is set to the sideways posture, the posture is detected by the lever member posture detection member 18, and the power supply to the driving motor 6 by the driving means 10 is stopped.

In the above example, similarly to the example shown in FIG. 2, even if the lever member 7 is not in the sideways posture, it is forcibly and automatically set to the sideways posture when an earthquake occurs, and the operator escapes. Road can be secured.

Next, as a configuration for setting the lever member 7 in a sideways position, an example in which a so-called magnet catch that does not include a push rod in place of the above-described solenoid having a push rod is used as the lever operating means 8 will be described. explain. In the drawings used in the following description, two lines extending from the solenoid indicate wiring, and when the wiring has an arrow mark, it indicates that power is being supplied. Preface what it means to be down.

FIG . 7 shows still another embodiment of the present invention . In this embodiment, the lever member 7 is provided with
The permanent magnets 172 and 173 of different poles are fixed side by side, and the magnet catch 174 forming the lever operating means 8
The one having a magnetic pole at a position facing the permanent magnets 172 and 173 is used.

The magnetic pole of the magnet catch 174 is supplied with electric power via the drive means 10 when a predetermined seismic intensity is detected by the seismic sensor 17 so that an excited state is set. When excited, a magnetic force of the same polarity as the permanent magnet of the opposing lever member 7 can be generated. For this reason, at the time of non-excitation due to the stop of power supply, it functions as a magnetic material magnetically attracted by the permanent magnets 172 and 173.

Since the present embodiment has the above configuration,
When the predetermined seismic intensity is not detected by the seismic sensor 17, power is not supplied to the magnet catch 174 via the driving means 10, so that the non-excited state is maintained. In this state, the permanent magnet 1 on the lever member 7 side
72, 173, the permanent magnets 172, 17
3, the magnet catch 174 is magnetically attracted, and the lever member 7 can be set to the upright position ( see FIG. 7A ).

When a predetermined seismic intensity is detected by the seismic sensor 17, the magnet catch 174 is supplied with electric power via the driving means 10 to set the excitation state. When the magnet catch 174 is excited, the magnetic poles facing the permanent magnets 172, 173 have the same polarity as those of the permanent magnets 172, 173, so that they repel each other, and the lever member 7 sways to the sideways position. ( See FIG. 7B ).

When the lever member 7 is set to the sideways posture, it is determined that the posture is the lever member posture detection member 18.
Is given to the driving means by the
Then, the suspension of power supply to the drive motor 6 is maintained.

In this embodiment, since the lever member 7 is set to the sideways position by the magnetic repulsion, the strength of the magnetic force of the magnet catch 174 becomes a problem. An attempt to increase the magnetic force increases the supply current, which is not only uneconomical, but also causes a problem of heat loss. However, in the present embodiment, since the lever member 7 is set in the upright position parallel to the front surface of the storage shelves and the lever member 7 is in a state parallel to the direction of gravity action, the lever member 7 swings in the upright position. There is almost no component force generated in the moving direction. Accordingly, it is possible also to swing without repulsion itself was so large, Ru can be an economical structure by can be reduced supply current as described above.

According to the embodiment shown in FIG . 7 , the power supply to the magnet catch 174 constituting the lever actuating means 8 is limited only when the lever member 7 is set to the sideways position, so that the power consumption is reduced. There is an advantage that it can be used.

[0064] In the above examples, the power supply control and the power supply control to the solenoid 16, 16 0, 16 3 or magnetic calibration pitch 174 to the drive motor 6, the relay is disposed in the feed path This is performed by switching the operation state.

On the other hand, in each of the above-described examples, it is assumed that the control by the driving means 10 is capable of supplying power such as during a non-power failure. Can be obtained. That is, the driving means 1
0 is provided with the backup power supply 10A, so that power can be supplied from the backup power supply 10A to the driving means 10 even when the power supply is stopped, for example, when an earthquake occurs. In the event of occurrence, the escape path can be secured between the storage shelves by forcibly setting the lever member 7 to the sideways position.

Although the above embodiment has been described on the assumption that a motor is used as the drive source for moving the storage shelves, the present invention is not limited to such a configuration.
For example, it is also possible to move the storage shelf manually.

As a mechanism for moving the shelves in this case, a handle is provided on the side wall of the shelves, and the handle and the wheels can be interlocked via an endless transmission member and a speed reduction mechanism. To move the shelves. Therefore, even in such a configuration, it is possible to equip the solenoid or the magnet catch described in the above embodiment. However, in this case, unlike the above-described example, since there is no drive motor, a power supply as a power supply unit is often not provided. Therefore, in order to cope with such a situation, a power supply unit having a member such as a relay capable of opening and closing the power supply path by the seismic sensor 17 is provided in the driving means, and when the predetermined seismic intensity is not detected, the power supply path is connected. It is desirable to shut off the power and supply power to the solenoid or the magnet net catch from the power supply unit via the driving means when the predetermined seismic intensity is detected by the seismic sensor 17.

[0068]

As described above, according to the first to fourth aspects of the present invention, the lever member can be automatically and forcibly set to the sideways position. It is possible to automatically secure the gap as a.

In particular, since the lever member can be automatically set to the sideways position, it is possible to secure a clearance as an escape route for the operator in an environment where the shelves themselves are likely to be inadvertently moved, for example, during an earthquake. Therefore, it is possible to prevent a situation in which the operator is exposed to a dangerous state.

Further, according to the third aspect of the present invention, even when the power supply to the members to which power is to be supplied is stopped, as in the case of an earthquake, the power supply is maintained by the backup power supply. Regardless of the supply state, the gap for the passage can be automatically formed. Moreover, when the lever member is set to the sideways position,
Because the storage drive is set to the inactive state,
It is prevented from carelessly as storeroom shelf moves, even a situation like path for escape is closed Ru can be prevented.
