Description

  The present invention relates to a shelf device in which a plurality of shelves are arranged in a collective manner, and in particular, at least one shelf usually has substantially the same function as a fixed shelf, and if necessary, a movable shelf As a result, it is possible to make it function as an enhanced utility.

  A conventionally known mobile shelf device has a plurality of mobile shelves arranged in a discrete manner, and when an article is taken in or out, the width required only on the front surface of the movable shelf to be taken in or out. Thus, the use efficiency of the space is increased. The mobile shelf can be given the following functions by devising the configuration.

(1) Security function A security function is provided by converging a plurality of moving shelves and locking them in an unmovable state in that state. All the movable shelves constituting the electric movable shelf may be converged and locked, or the movable shelf may be divided into blocks, and the movable shelves belonging to a specific block may be converged and locked. In order to avoid touching the contents of the outermost moving shelves among the converged moving shelves, the entrance / exit of the outermost moving shelves, that is, the frontage, is close to the wall of the building, etc. It is blocked by a kind. The lock can be performed by mechanical locking, and in the case of an electric movable shelf, the lock can be released only by a specific key or by a specific user who is recognized by a living body.

(2) Multi-passage function A plurality of moving shelves constituting an electric moving shelf are divided into a plurality of blocks so that a work passage can be formed in at least one place in each block, corresponding to at least the number of blocks. A multi-passage function capable of forming a plurality of working passages is provided. For example, when an electric moving shelf device is configured with 20 moving shelves that use a motor as a drive source, each moving block is divided into 4 blocks for every 5 moving shelves, and the moving shelf for other blocks is moved for each block. Regardless of the movement, the moving shelf in the block is moved so that at least one working path can be formed in each block.

  Whether the mobile shelf device has the above-described security function or the multi-passage function, it is necessary to lock at least one of the mobile shelves constituting the mobile shelf device so that the mobile shelf device cannot move. There are two types of locking devices for moving shelves, one that locks mechanically, and one that makes motors impossible to drive in the case of an electric moving shelf. In the case of an electric moving shelf, it is conceivable to use a motor with a brake device (brake motor) and use the brake device as a lock device.

  Mechanical locking devices include those that lock the power transmission mechanism from the rotating handle to the drive wheels inoperably, and the hook-shaped locking members provided on the moving shelf in holes formed on the installation floor of the moving shelf. There are things that pierce and lock the movable shelf so that it cannot move, and there are various kinds of specific configurations.

  The moving shelf has traveling wheels before and after the moving direction, and usually one of the front and rear wheels is the drive wheel. When the mechanical locking device locks the power transmission mechanism, the drive wheel is locked so as not to rotate, and the other wheel (this is referred to as a “driven wheel” with respect to the drive wheel). Can rotate. Therefore, when converging multiple moving shelves to provide a security function and locking the power transmission mechanism of the outermost moving shelf, consider that the driving wheels are positioned outside the driven wheels. There is a need. The reason is that if the pulling force or pressing force is applied to the outermost moving shelf among the moving moving shelves that are converged, the driving wheel is locked and cannot rotate. This is because a load is applied to the contact point between the wheel and the rail on which the driving wheel is mounted, resulting in a large braking force. Assuming that the driven wheel of the outermost moving shelf is located outside the driving wheel, when a force is applied to the outermost moving shelf in a direction away from the other moving shelf, the driven wheel is Rolls on the rail and does not apply braking force.

  In the case of a lock device that pierces a bowl-shaped lock member provided in the moving shelf into a hole formed in the installation floor of the moving shelf, the position of the moving shelf that can be locked is determined in advance. Therefore, a block configuration including a plurality of moving shelves for providing a security function is also determined in advance, and there is a problem that the block configuration cannot be changed.

  Various electric movable shelves with multi-passage functions have also been proposed. The invention described in Patent Document 1 is one of them, and has a pair of proximity sensors for detecting the proximity of the other shelf on the front surface of one of the adjacent movable shelves, and signal detection of at least one proximity sensor. Having a mode switching means for switching between a multi-passage mode for stopping movement of the moving shelf on the condition of 1 and a 1-passage mode for stopping movement of the moving shelf on the condition of detection signals from both of the pair of proximity sensors. It is a feature.

  In Patent Document 2, when a sensor detects that an adjacent moving shelf has approached a certain distance, the moving shelf is moved in the same direction as the moving direction of the adjacent moving shelf, and the distance from the adjacent moving shelf is constant. There is described an electric movable shelf that realizes a multi-path by controlling to keep the movable shelf, and rejecting the driving of the movable shelf when the detecting means detects the entry into the passage between adjacent movable shelves. The other moving shelves that are separated by the moving shelves whose drive has been rejected can be arbitrarily moved in units of the separated moving shelves, thus realizing a multi-passage type moving shelf apparatus.

  Patent Document 3 includes a passage width measuring unit that measures a passage width formed between at least one of the adjacent moving shelves and the other moving shelf, and has a preset maximum passage width between adjacent shelves. An arbitrary number of passages having an arbitrary width within the range are allowed to be formed at an arbitrary position, and the drive of the motor of the shelf is stopped when the measured value of the passage width measuring means reaches the maximum value. An electric moving shelf is described.

Japanese Patent Laid-Open No. 09-77216 JP 2006-95332 A JP 2007-22770 A

  The present invention is intended to provide a shelf device that can realize both the security function and the multi-passage function. However, for the following reason, the shelf device having both the security function and the multi-passage function is provided. It has not been realized so far. That is, in the electric moving shelf, one of the traveling wheels before and after the moving direction is a driving wheel that is rotationally driven by a motor, and the power transmission mechanism from the motor to the driving wheel is a reduction mechanism. Therefore, with respect to the rotational force transmitted from the drive wheel side to the motor by pushing or pulling the movable shelf, the power transmission mechanism becomes a speed increasing mechanism, and the resistance force increases. However, since the resistance is not so great that it cannot be moved when the moving shelf is pushed or pulled manually, a security effect cannot be expected. In order to provide a security effect, at least the outermost movable shelf of the group of movable shelves has the resistance of the power transmission system from the drive wheel side through the power transmission mechanism to the motor, and the manual movement is a movable shelf. It must be so large that it cannot be moved.

  In order to provide the security function described above, a moving shelf in which the resistance of the power transmission system from the drive wheel side to the motor is so large that it cannot be moved by human power is also included in the plurality of moving shelves constituting the moving shelf device. One of them must be able to be moved as needed. Since the moving shelf has a large resistance when driven by a motor, the moving shelf is slower in movement and consumes more power than a moving shelf having a small resistance in the power transmission system. Accordingly, the movable shelf configured as described above is a movable shelf that functions as a movable shelf that is divided into a plurality of movable shelf groups, that is, temporarily functions as a fixed shelf in an electric movable shelf apparatus having a multi-passage function. Suitable as

  It is an object of the present invention to provide a shelf apparatus that can further develop the technology of the conventional shelf apparatus as described above and have a security function or a multi-passage function. .

The shelf apparatus according to the present invention is
A plurality of shelves provided with a motor that moves the shelf by rotationally driving the traveling wheel, a motor control unit that controls the rotation of the motor according to a command signal, and a control unit that includes the motor control unit are arranged in a convergent and discrete manner A shelf device,
At least one of the plurality of shelves includes a brake device that can apply a braking force to the motor, and a changeover switch that switches the at least one shelf to be movable or fixed. The wheel shafts of the traveling wheels before and after the moving direction are connected by a connecting member so as to be rotatable synchronously,
At least one of the control unit of the plurality of shelves, the changeover switch is added the braking force of the brake device and Ru is switched to the fixed side to the motor, and the changeover switch is switched to the movable side of the brake device And a brake control unit for releasing the braking force from the motor .

Shelf becomes solid Teitana virtually identical when the changeover switch is switched to the fixed side, it is impossible to move the rack manually. Therefore, by using the shelf having the above-described configuration as the outermost shelf of the group of converged shelves, a shelf device with excellent security performance can be obtained. In addition, since the driving wheels of the moving direction back and forth is connected by a connecting member, it is difficult even to move an attempt is made to move in any direction the shelf by the pressing force or tensile force by hand.

  The shelf having the above-described configuration can also be used as a shelf that separates one moving shelf group and another moving shelf group in the multi-path type electric moving shelf apparatus. When an electric mobile shelf device is operated in a multi-passage system, a mobile shelf that separates one mobile shelf group from another mobile shelf group is configured as at least one shelf in the shelf device according to the present invention, and this shelf is Locks immovable and functions as a fixed shelf.

  Hereinafter, embodiments of a shelf device according to the present invention will be described with reference to the drawings.

  An outline of an embodiment of a shelf device according to the present invention is shown in FIG. In the example shown in FIG. 1, five movable shelves 10 represented by A, B, C, D, and E are arranged so as to be movable along guide rails laid on the floor. Fixed shelves are installed before and after the five moving shelves 10 in the moving direction, and the five moving shelves 10 can move between these fixed shelves. Each movable shelf 10 has an appropriate number of traveling wheels at the bottom, and the traveling wheels are placed on guide rails. Each traveling shelf 10 is configured to move while the traveling wheels of each moving shelf 10 are rotated on a guide rail by being rotationally driven by a drive motor. A drive motor is provided on each movable shelf. Of the five electric movable shelves represented by A, B, C, D, and E, the electric movable shelf 100 denoted by C can be handled as if it were a fixed shelf, and the shelf device according to the present invention. It has a characteristic configuration among the moving shelves that constitute.

  Each of the movable shelves 10 and 100 has a surface for taking in and out stored articles, and this surface is referred to as a frontage surface. Assuming that the front face is the front of the movable shelf, FIG. 1 is a side view seen from a direction orthogonal to the front face, and side panels are attached to the side faces of the movable shelves 10 and 100. On the side panels of the movable shelves 10 and 100, operation switches 41 and 42 are attached to the right side and the left side of the side panel, respectively, at a height position where the user can easily operate in a standing posture. The operation switch 41 is a switch for moving a moving shelf provided with the operation switch to the left as viewed from the side surface shown in FIG. 1 and forming a passage on the right side of the moving shelf. The operation switch 42 is a switch for moving the moving shelf to the right as viewed from the side surface shown in FIG. 1 and forming a passage on the left side of the moving shelf.

  By operating the operation switches 41 and 42, the moving shelf can be moved, and a working path can be formed between desired moving shelves. There are various types of work path formation control methods by operating the operation switch. One is that the moving shelf moves to the left while the operation switch 41 is pressed to the left, and the moving shelf moves to the right while the other operation switch 42 is pressed to the right, When the operation of the operation switches 41 and 42 is stopped, the moving shelf stops. The other is that when the operation switch 41 of one moving shelf 1 is pressed, which moving shelf should be moved in which direction to form a work path on the right side of the moving shelf, When the switch 42 is pressed, in order to form a work path on the left side of the moving shelf, it is automatically determined which moving shelf should be moved in which direction, and the movement of each moving shelf is controlled according to the determination. To do. The driving system of the electric movable shelf used in the present invention is arbitrary and any driving system may be used.

  In the operation mode shown in FIG. 1A, the work path 1 is between the left fixed shelf 12 and the movable shelf 10 indicated by A, and the work path is between the right fixed shelf 12 and the movable shelf 10 indicated by E. 2 is formed. In the usage mode as a normal electric movable shelf apparatus, the movable shelf 100 indicated by C is substantially the same as the fixed shelf as will be described in detail later, and is used as a movable shelf by performing a special switching operation. Do not move unless you switch to an operable mode. Therefore, in the operation mode shown in FIG. 1A, a multi-passage in which a work passage can be formed on the right side or the left side of any mobile shelf by the left block 1 and the right block 2 divided by the mobile shelf 100, respectively. This constitutes an electric moving shelf device of the type. Hereinafter, the electric movable shelf 100 is referred to as a “movable fixed shelf”.

  In the operation mode shown in FIG. 1A, it is assumed that an operation for providing a security function, for example, a convergence operation member is operated. By this operation, the movable fixed shelf 100 indicated by C starts to move in the left direction indicated by the arrow in FIG. 1B, and accordingly, the movable shelf 10 indicated by A and B also moves in the left direction. In this operation, as shown in FIG. 1 (c), each moving shelf constituting the block 1 comes close to the fixed shelf, and in the block 2, two work paths are indicated between the moving shelves indicated by C and D and indicated by E. It is formed between the movable shelf 10 and the fixed shelf 12.

  When the convergence operation is finished, the movable fixed shelf 100 cannot be moved by an operation such as stopping the power supply to the movable fixed shelf 100 indicated by C or stopping the power supply to the motor of the movable fixed shelf 100. To. FIG. 1 (d) shows that the movable fixed shelf 100 is in an inoperable state. The movable fixed shelf 100 is operated by operating a key or the like possessed by a specific user, or biometric recognition. It cannot be moved unless it is operated by a specific person. In this way, the fixed shelf 12 on the left side and the movable shelves indicated by A, B, and C converge, and the putting in and out of articles to and from these shelves are restricted. Further, in this operation mode, a security effect can be enhanced by fitting a panel on the right front surface of the movable fixed shelf 100 and locking the panel so that only the specific person can remove the panel. Alternatively, the security effect can be enhanced by using a special key or by allowing the movable fixed shelf 100 to be moved only by a specific person by biometric recognition.

  The movable shelf 10 in the example of the electric movable shelf apparatus can be applied to the same configuration as a conventionally known electric movable shelf, but the configuration of the movable fixed shelf 100 indicated by C is a characteristic feature of the present invention. It has a certain configuration. Hereinafter, the drive system and control system of the movable fixed shelf 100 will be described.

  FIG. 2 shows an example of the drive system. The movable fixed shelf 100 has a base 14 with a rectangular planar shape as a base, and a ceiling that connects the base 14, an appropriate number of supports 16 standing on the base 14, and the upper end of each support 16. A frame of the movable fixed shelf 100 is constituted by the plates. An appropriate number of shelves (not shown) are supported by the columns 16 arranged at predetermined intervals in the frontage direction. One side surface of the movable fixed shelf 100 is covered with a side plate 15, and the operation switches 41 and 42 are attached to the left and right sides of the side plate 15 at appropriate height positions. On the inner surface side of the side plate 15, the control unit 20 is arranged in a circuit board. A changeover switch 38 for switching the movable fixed shelf 100 between the movable side and the fixed side is also attached to the side plate 15.

  Two rotation shafts are supported on the underframe 14 in the longitudinal direction of the underframe 14, and traveling wheels are fixed to the respective rotation shafts at regular intervals. The traveling wheels are placed on the guide rails, and the movable fixed shelf 100 can move in the width direction of the underframe 14, that is, the direction orthogonal to the front facet, by rotating the traveling wheels on the guide rails. The two rotating shafts are supported in parallel with each other on the front side and the rear side in the moving direction of the movable fixed shelf 100. The rotational force of the motor 30 is transmitted to one of the two rotating shafts via a power transmission mechanism including a gear or a sprocket and a chain. Sprockets having the same diameter are fixed to the two rotary shafts at the same position in the length direction, and an endless chain 18 is hung on these sprockets. Therefore, the rotational force of the motor 30 is transmitted to one rotating shaft and also to the other rotating shaft through the sprocket and the chain 18, and the traveling wheels before and after the moving direction of the movable fixed shelf 100 are moved together. The drive wheel is driven to rotate by the motor 30.

  The movable fixed shelf 100 is movable between a sprocket integrally provided on a wheel shaft that connects the traveling wheels on the front and rear sides in the moving direction so as to be integrally rotatable, and a chain 19 that connects the sprockets of the wheel shafts. A connecting member that rotates the traveling wheel shafts before and after the moving direction of the fixed shelf 100 in synchronization is configured.

  The motor 30 includes a brake device 31. The brake device 31 is configured to be switched between a mode in which a braking force is applied to the motor 30 and a mode in which the braking force is released from the motor 30 by a control signal from the brake control unit. The motor 30 has a built-in motor clutch that can connect and disconnect the output shaft and the rotor of the motor.

  The motor clutch is, for example, an electromagnetic clutch, and can take a mode in which the motor 30 and its output shaft are coupled by a control signal from the clutch control unit and a mode in which the motor 30 and its output shaft are separated. When the motor clutch is present, the brake device 31 is constantly applied with a braking force, and the braking force is transmitted to the output shaft by the operation of the clutch. The mode is switched to a mode in which the rotational force to the output shaft is cut off. Alternatively, the control of the clutch and the brake device 31 by the clutch control unit and the brake control unit may be synchronized so that the clutch disconnects the motor 30 and its output shaft at the same time as the brake device 31 releases the braking force.

  The operation modes of the brake device 31 and the motor clutch are switched according to the switching mode of the changeover switch 38. When the changeover switch 38 is in a mode of switching the movable fixed shelf 100 to the movable side, the brake control unit controls the operation of the brake device 31 so that the braking force is applied to the motor 30, and the motor 30 And the clutch control unit controls the operation of the motor clutch so as to connect the output shaft.

  Next, an example of a control system used for the movable fixed shelf 100 will be described. Since there are several examples of the configuration of the control system as well as the configuration of the drive system, they will be described as different embodiments.

3 and 4 show a first embodiment. In FIG. 3, reference numeral 20 indicates a control unit provided in the movable fixed shelf 100. The control unit 20 includes a microcomputer or a central processing unit (CPU) and is mounted on a circuit board. The control unit 20 includes the following functional units indicated by blocks in FIG.
A right operation detection unit 21 that detects an operation of the right operation switch 41.
A left operation detection unit 22 that detects an operation of the left operation switch 42.
A switch detection unit 23 that detects the switching mode of the switch 38.
A position detector 24 that detects the position of the movable fixed shelf 100 based on a detection signal from the ultrasonic sensor 43 that detects the passage width.
A motor control unit 27 that controls normal rotation, reverse rotation, and stop of the motor 30 based on signals from the right operation detection unit 21, the left operation detection unit 22, and the position detection unit 24.
A brake control unit 28 that controls the operation of the brake device 31 based on a signal from the switch detection unit 23.

  The right operation switch 41, the left operation switch 42, the ultrasonic sensor 43, the approach sensor 44, the changeover switch 38, the motor 30, and the brake device 31 are arranged outside the control unit 20, and are connected to the control unit 20 as described above. Has been. The motor 30 is a driving motor for the movable fixed shelf 100 and includes the brake device 31 as described above. The motor 30 is controlled to rotate forward, reverse, and stop by a control signal from the motor control unit 27. The brake device 31 is controlled to be turned on / off by the control signal from the brake control unit 28, that is, the application of the brake force to the motor 30 and the release of the brake force are controlled.

  The motor control unit 27 and the brake control unit 28 control the operation of the motor 30 and the brake device 31 by controlling the operation of an appropriate drive circuit or switch. The drive circuit or switch is a motor control unit. 27, it will be described as being included in the brake control unit 28. The same applies to other examples of dictation.

  The changeover switch 38 is a switch for switching to a mode in which the movable fixed shelf 100 functions as a movable shelf or a mode in which the movable fixed shelf 100 functions as a fixed shelf. When the changeover switch 38 is switched to the fixed side, the brake control unit 28 turns on the brake device 31 and brakes the motor 30. As can be seen from the configuration of the drive system shown in FIG. 2, the front and rear wheel drive system is achieved by connecting the rotation shafts of the movable fixed shelf 100 before and after the moving direction through the chain 18 and the sprocket. When the braking force is applied, the braking force is applied to the front and rear wheels, and the movable fixed shelf 100 can be substantially regarded as a fixed shelf.

  The right operation switch 41 and the left operation switch 42 have been described with reference to FIG. The ultrasonic sensor 43 emits ultrasonic waves toward an adjacent moving shelf, and measures the distance based on the difference between the time of emission and the time reflected and returned from the adjacent moving shelf. Is configured. As a passage width measuring device, instead of the ultrasonic sensor 43, the swing arms provided on adjacent moving shelves are connected to each other so that they can rotate relative to each other, and the rotation angle of the swing arm is determined according to the distance between the adjacent moving shelves. You may employ | adopt the mechanistic measuring system which measured the distance between the adjacent mobile shelves using different things. In addition, a passage width measuring device of an appropriate method can be selected and employed.

  The position detection unit 24 of the control unit 20 detects a positional relationship such as a passage width and a stop position formed between the movable fixed shelf 100 and the moving shelf adjacent thereto based on the detection signal of the ultrasonic sensor 43. To do. When the position detection unit 24 approaches the adjacent movable shelf to a predetermined distance and the passage width becomes narrow and reaches the stop position, the motor control unit stops driving the motor 30 and stops the movement of the movable shelf.

  The control unit 20 may be connected by a communication path for exchanging signals with the control unit of the adjacent mobile shelf. For example, in the example shown in FIG. 3, the right communication line transfers the rightward signal generated by the right operation detection unit 21 to the right adjacent shelf, and inputs the leftward signal transferred from the right adjacent shelf, The passage width signal generated by the position detector 24 based on the detection signal of the ultrasonic sensor 43 is transferred to the right adjacent shelf. The left communication line transfers a leftward signal generated by the left operation detection unit 22 to the left adjacent shelf, inputs a rightward signal transferred from the left adjacent shelf, and generates a path generated by the left adjacent shelf. Input the width signal. The left communication line is used as a communication path for transmitting a signal indicating that the left communication line should be moved to the left side to the movable shelf 10 indicated by B when the convergence operation member of the movable fixed shelf 100 indicated by C is operated. can do.

  An example of the operation of the control system shown in FIG. 3 is shown in FIG. Each step is represented as S1, S2, S3,. First, it is determined whether the changeover switch 38 is ON (S1). When the changeover switch 38 is ON, the movable shelf 100 is switched to the movable side. If the changeover switch 38 is not turned ON, the brake control unit 28 controls the operation of the brake device 31 so as to maintain the braking force by the brake device 31 (S8). Have the function of.

  When the changeover switch 38 is turned ON, the brake control unit 28 controls the brake device 31 so as to release the braking force by the brake device 31 (S2). When the changeover switch 38 is switched to ON, the process proceeds to a determination step (S3) for determining whether any of the operation switches 41 and 42 has been operated. If neither operation switch 41, 42 is operated in this step (S3), the process returns to step S1. Therefore, once the changeover switch 38 is turned ON, when the changeover switch 38 is turned OFF without any operation switches 41 and 42 being operated, the brake device 31 applies a braking force to the motor 30 ( S8). When any of the operation switches 41 and 42 is operated in step (S3), the motor control unit 27 causes the motor 30 to move so that the movable fixed shelf 100 moves in the direction indicated by the operation switch 41 or the operation switch 42. Drive (S4).

  As the motor 30 is driven, the movable fixed shelf 100 moves in the designated direction. Based on the detection signal from the ultrasonic sensor 43, the position detection unit 24 detects an interval between adjacent moving shelves and determines whether or not the stop position has been reached (S5). If the stop position is not reached, the driving step (S4) of the motor 30 is continued. If the stop position is reached, the motor control unit 27 stops driving the motor 30 (S6). Further, the switching mode of the changeover switch 38 is confirmed (S7). If the changeover switch 38 is not turned on, that is, if it is not changed to the fixed side, the brake control unit 28 turns on the brake device 31 (S8). The braking force is applied to the motor 30. Further, communication with the adjacent shelf is cut off (S9), and the movable fixed shelf 100 is substantially made a fixed shelf.

  According to the first embodiment described above, by switching the changeover switch 38, the movable fixed shelf 100 can be switched to a mode that functions substantially as a fixed shelf and a mode that functions as a movable shelf. The drive system of the movable fixed shelf 100 is of a type in which the front and rear wheels are driven together as described above, and the braking force applied to the motor 30 is also applied to the front and rear wheels. It is difficult to move the shelf 100 even if it is pushed or pulled in the front-rear direction. Therefore, the movable fixed shelf 100 and another movable shelf having the same structure as that of the conventional electric movable shelf are converged, and the movable fixed shelf 100 is located outside the group of converged movable shelves and specified. It is impossible to function as a movable shelf without using a key or biometric authentication. By doing so, the security effect of a group of mobile shelves can be enhanced.

  Further, if a plurality of movable shelves are arranged on both sides of the movable fixed shelf 100 as a boundary, and the changeover switch 38 is switched so that the movable fixed shelf 100 functions as a fixed shelf, the movable fixed shelf 100 is arranged on both sides of the movable fixed shelf 100, respectively. A multi-passage type moving shelf device capable of forming at least one work passage can be configured. Since the movable fixed shelf 100 can also be temporarily functioned as a moving shelf as required, it is easy to change the layout of the multi-passage type moving shelf device.

  In the first embodiment shown in FIG. 3, the entry sensor 44 detects that a human or other object has entered the work path formed. With this detection signal, the moving shelf that is moving can be stopped urgently, or it can be interlocked with the detection signal so that a work path cannot be formed at another position. The detailed description is omitted because it is not related to the present invention.

  In the above embodiment, the brake device 31 may be regarded as substantially the same as a lock device that can lock the movable shelf so as not to move. The same applies to the brake device 31 in the second embodiment to be described next.

  Next, a second embodiment shown in FIG. 5 will be described. This embodiment is different from the first embodiment shown in FIG. 3 in that the motor 30 is provided with a clutch 32 between the output shaft and a vibration sensor 45, and is controlled. The unit 20 includes a vibration detection unit 25 and a clutch control unit 29. The vibration detection unit 25 outputs a signal when a certain level of vibration is detected from the detection signal of the vibration sensor 45. The clutch control unit 29 controls the operation of the clutch 32 based on signals from the power supply detection unit 23 and the vibration detection unit 25.

  The clutch 32 couples the motor 30 and its output shaft, and releases this coupling. The clutch 32 is controlled to be turned on and off by a control signal from the clutch control unit 29. The vibration sensor 45 mainly detects an earthquake, and an output signal of the vibration sensor 45 is input to the vibration detection unit 25. The vibration detection unit 25 outputs a signal when a certain seismic intensity is reached, and the clutch control unit 29 that receives this output signal operates the clutch 32. Even if the clutch 32 is coupled to the motor 30 and its output shaft. The motor 30 and its output shaft are separated.

  The operation of the second embodiment will be described with reference to FIG. First, it is determined whether the changeover switch 38 is ON (S11). When the changeover switch 38 is turned ON, the brake control unit 28 controls the brake device 31 so as to release the braking force by the brake device 31 (S12). Next, the process proceeds to a determination step (S13) as to whether or not any of the operation switches 41 and 42 has been operated. If neither of the operation switches 41 and 42 is operated in this step (S13), the process returns to step S11.

  When any of the operation switches 41 and 42 is operated in step (S13), the clutch is turned on (S14). That is, the clutch control unit 29 controls the clutch 32 to couple the motor 30 and its output shaft. Further, the motor control unit 27 drives the motor 30 so that the movable shelf 100 moves in the direction indicated by the operation switch 41 or the operation switch 42 (S15).

  Next, the process proceeds to the vibration detection step (S16). In this step (S16), the vibration detector 25 calculates the detection signal of the vibration sensor 45, and determines whether or not a vibration having a certain seismic intensity or more has occurred. When vibration with a certain seismic intensity or more occurs, the clutch 32 is turned off, that is, the coupling between the motor 30 and its output shaft by the clutch 32 is released (S17). As a result, the motor 30 is released from the driving mechanism of the traveling wheel, so that the rotational resistance of the traveling wheel of the movable fixed shelf 100 is reduced. When the guide rail moves together with the floor surface due to the earthquake, the traveling wheel rolls on the guide rail. The movable fixed shelf 100 can obtain a seismic isolation effect.

  After step S17, the process returns to the vibration detection step (S16), and if the detected seismic intensity has fallen below a certain level, the operation loop for the seismic isolation is exited, and the step of determining whether the clutch is on (S29). ) When the seismic isolation operation is performed due to an earthquake, the clutch 32 is turned off. Therefore, the clutch 32 is turned on (S31), and the process proceeds to a determination step (S19) as to whether or not it is the next stop position. If the seismic isolation operation has not been performed, the clutch 32 is on, and the process directly proceeds to step S19.

  If the movable fixed shelf 100 has not reached the stop position in the determination step (S19) as to whether or not it is the stop position, the process returns to step (S16). If the stop position is reached, the motor control unit 27 stops driving the motor 30 (S20), and the process proceeds to a determination step (S21) as to whether or not the next changeover switch 38 is on. In this determination step (S21), it waits for the changeover switch 38 to be turned off, that is, the movable fixed shelf 100 is switched to a mode that functions as a fixed shelf. When the changeover switch 38 is turned off, the brake device 31 is turned on (S22), Further, the communication with the adjacent shelf is interrupted (S24), and the operation is terminated. When the brake device 31 is turned on and the clutch 32 is turned on, the braking force of the brake device 31 is applied to the driving mechanism of the traveling wheel via the motor 30, the clutch 32, and the output shaft of the motor 30, and further, When the communication is interrupted, the movable fixed shelf 100 becomes substantially the same as the fixed shelf.

  If the changeover switch 38 is not turned on in step S11, that is, if the movable fixed shelf 100 is not switched to the movement mode, the brake device 31 is turned on (S25), the clutch 32 is turned on (S26), and communication with the adjacent shelf is performed. Is maintained in the shut-off state (S27). In this state, the process proceeds to the vibration detection step (S28), and when vibration of a certain seismic intensity or more is detected, the clutch 32 is turned off (S30) to exhibit the seismic isolation effect, and the process returns to step S28. While the vibration with the seismic intensity exceeding a certain level continues, the operation for demonstrating the seismic isolation effect is continued.

  According to the second embodiment described above, the clutch 32 is added to the first embodiment, and the clutch 32 is operated by the detection signal of the vibration sensor 45 to disconnect the motor 30 and its output shaft. The movable shelf 100 can have a seismic isolation function. Therefore, even if the movable fixed shelf 100 is substantially in the same state as the fixed shelf, the movable fixed shelf 100 is switched to a mode in which a seismic isolation function is exhibited by the occurrence of an earthquake, and the movable fixed shelf 100 is prevented from falling or falling. be able to.

  Next, a third embodiment shown in FIG. 7 will be described. This embodiment differs from the embodiment shown in FIGS. 3 and 5 in that the movable fixed shelf 100 includes a converging operation member 46, and the group including the movable fixed shelf 100 by operating the converging operation member 46. It is the point which comprised so that the movement shelf of may converge. The convergence operation member 46 is operated when a plurality of moving shelves constituting one block are converged to have a security function, and is attached to, for example, a side panel of the movable fixed shelf 100. In FIG. 7, the operation signal of the convergence operation member 46 is input to the control unit 20, and the convergence control unit 26 provided in the control unit 20 moves the movable fixed shelf 100 toward a predetermined convergence position based on the operation signal. The motor 30, the brake device 31, and the clutch 32 are controlled so as to be moved. Other configurations are the same as those of the embodiment shown in FIG.

  An operation example of the third embodiment will be described with reference to FIG. First, it is determined whether or not the changeover switch 38 is ON (S41). When the changeover switch 38 is turned ON, the brake control unit 28 controls the brake device 31 so as to release the braking force by the brake device 31 (S42). Next, the process proceeds to a step of determining whether or not the convergence operation member 46 has been operated (S43). If the convergence operation member 46 is not operated in this step (S43), the process returns to step S41.

  When the convergence operation member 46 is operated in step (S43), the clutch is turned on, that is, the clutch control unit 29 controls the clutch 32 to couple the motor 30 and its output shaft (S44). Further, the motor control unit 27 of the movable fixed shelf 100 drives the motor 30 so that the group of movable shelves including the movable fixed shelf 100 converge in a predetermined direction (S45), and drives the movable fixed shelf 100 in the indicated direction. To do.

  Next, the process proceeds to the vibration detection step (S46). The following operation is the same as that of the second embodiment. In step (S46), it is determined whether or not a vibration having a certain seismic intensity or more has occurred. 32 is turned off, that is, the coupling between the motor 30 and its output shaft by the clutch 32 is released (S47). Thus, since the motor 30 is disconnected from the driving mechanism of the traveling wheel, when the guide rail moves together with the floor surface due to the earthquake, the traveling wheel rolls on the guide rail, and the movable shelf 100 can obtain the seismic isolation effect.

  After step S47, the process returns to the vibration detection step (S46), and if the detected seismic intensity is reduced below a certain level, the operation loop for the seismic isolation is exited, and the step of determining whether or not the clutch is on (S59). ) If the seismic isolation operation is performed due to an earthquake, the clutch 32 is turned off. Therefore, the clutch 32 is turned on (S61), and the process proceeds to a determination step (S49) for determining whether or not it is the next stop position. If the seismic isolation operation has not been performed, the clutch 32 is on, and the process directly proceeds to step S49.

  If the movable fixed shelf 100 has not reached the stop position in the determination step (S49) as to whether or not it is the stop position, the process returns to step (S46). If the stop position is reached, the motor control unit 27 stops driving the motor 30 (S50), and the process proceeds to the next step (S51) for determining whether or not the changeover switch 38 is on. In this determination step (S51), it waits until the changeover switch 38 is turned off, that is, the movable fixed shelf 100 is switched to a mode that functions as a fixed shelf. When the changeover switch 38 is turned off, the brake device 31 is turned on (S52), the clutch 32 is turned on (S53), communication with the adjacent shelf is interrupted (S54), and the operation is terminated. When the brake device 31 is turned on and the clutch 32 is turned on, the braking force of the brake device 31 is applied to the driving mechanism of the traveling wheel via the motor 30, the clutch 32, and the output shaft of the motor 30, and the movable fixed shelf 100 is fixed. It becomes substantially the same as the shelf. In addition, when communication with the adjacent shelf is interrupted, the movable fixed shelf 100 and the adjacent shelf with the communication disconnected become shelves belonging to different blocks.

  If the changeover switch 38 is not turned on in step S41 and the movable fixed shelf 100 cannot be switched to the movement mode, the brake device 31 is kept on (S55), the clutch 32 is kept on (S58), Communication is interrupted (S57). In this state, the process proceeds to the vibration detection step (S58), and when vibration of a certain seismic intensity or more is detected, the brake device 31 is turned off (S59), the clutch 32 is turned off (S60), and the seismic isolation effect is exhibited. The process returns to step S56. While the vibration of a certain seismic intensity or higher continues, the operation for demonstrating the seismic isolation effect is continued. However, when the seismic intensity is equal to or lower than the predetermined seismic intensity, the loop for the seismic isolation is passed and the process returns to step S41.

  When the movable fixed shelf 100 moves in a predetermined direction by operating the convergence operation member 46, the other movable shelves that form a group together with the movable fixed shelf 100 also move in the same direction as the movable fixed shelf 100 and move in a group. The shelves converge. FIG. 1D described above shows a state in which the three movable shelves A, B, and C including the movable fixed shelf 100 have converged, and after these movable shelves have converged, a group of movable shelves. The brake device 31 and the clutch 32 of the outer movable fixed shelf 100 indicated by C among A, B, and C are both turned on, and the movable fixed shelf 100 becomes substantially the same as the fixed shelf. Therefore, if the convergence mode cannot be canceled only when operated by a specific person or by a specific person by biometric recognition, the security function cannot remove the stored items from the group of moving shelves. Can be given. In this case, if a door, a panel, or the like is provided on the front surface of the movable fixed shelf 100 and the door, the panel, or the like cannot be opened only by the key or the biometric recognition, the security function can be further enhanced.

  The movable shelves other than the movable fixed shelf 100 when the group of movable shelves move together with the movable fixed shelf 100 may be moved by the pressing force of the movable fixed shelf 100, You may make it move by control.

  In the embodiment of the shelf device described above, the shelf constituting the shelf device is an example of an electric movable shelf, but the technical idea according to the present invention can also be applied to a manual movable shelf. In the case of a manual moving shelf, since a drive motor is not provided, a lock device that can lock the shelf so as not to move is provided on at least one shelf corresponding to the movable fixed shelf 100. This locking device may be a mechanism that restricts the operation of a power transmission mechanism that transmits the rotational force of the rotation operation handle to the traveling wheel shaft, or a mechanism that fits a hook in a hole provided in the floor or the like as appropriate. This mechanism can be adopted. When locked with a locking device that restricts the operation of the power transmission mechanism, the shelf cannot be moved unless the force is applied about 100 times compared to when the lock is released, and the shelf cannot be moved. You can say. FIGS. 9 to 11 show an example (fourth embodiment) in which the technical idea according to the present invention is applied to a manually movable shelf, and shows an example of a mechanism incorporated in the movable fixed shelf 100.

  9 and 10, reference numeral 50 denotes a handle support panel that constitutes a part of the side plate of the shelf. A housing 60 of the drive mechanism is fixed to the inner surface side of the handle support panel 50. The housing 60 is formed in a box shape whose top and bottom are opened by a front panel 61, a rear panel 62, and a connecting member 63 that connects the front panel 61 and the rear panel 62 at a predetermined interval.

  The front panel 61 and the rear panel 62 are each provided with a bearing 53 at the center of the opposing surface, and the pipe shaft 51 is supported by the pair of bearings 53 so as to be rotatable around the center axis. One end portion of the tube shaft 51 protrudes outward from the handle support panel 50, and a hub 54 of the rotation operation handle 55 is fitted into the protruding end portion of the tube shaft 51. The rotation operation handle 55 and the hub 54 are integrally connected by a plurality of spokes 56. The hub 54 and the tube shaft 51 are integrally coupled, and the tube shaft 51 can rotate together with the rotation operation handle 55.

  On the outer periphery of the tube shaft 51, a sprocket 52 is fixed between the front panel 61 and the rear panel 62 of the housing 60, and a sprocket-like lock ring 58 is fixed after the sprocket 52. Accordingly, the sprocket 52 and the lock wheel 58 rotate together with the rotation operation handle 55. A chain is spanned between the sprocket 52 and a sprocket fixed to a traveling wheel shaft (not shown) below the sprocket 52. The diameter of the sprocket of the traveling wheel shaft is larger than the diameter of the sprocket 52, and the diameter of the rotation operation handle 55 is larger than the diameter of the sprocket 52, and the power transmission mechanism from the rotation operation handle 55 to the sprocket of the traveling wheel shaft is decelerated. The mechanism is configured. The traveling wheel shafts are arranged in the front and rear of the shelf in the moving direction, and the front and rear traveling wheel shafts are connected to each other so as to be synchronously rotatable by a connecting member including a sprocket having the same diameter and a chain as described with reference to FIG. Has been.

  A lock shaft 65 constituting a locking device is fitted in the tube shaft 51 so as to be slidable along the tube shaft 51. The front end portion of the lock shaft 65 protrudes from the front end of the tube shaft 51, and a lock operation knob 67 is fixed to the protruding end portion of the lock shaft 65. The rear end portion of the lock shaft 65 protrudes to the rear side of the rear panel 62, is bent downward at a right angle along the rear surface of the rear panel 62, and is further folded at a right angle. The folded portion of the lock shaft 65 is a lock end portion 66, which penetrates a hole formed in the rear panel 62 toward the inside of the housing 60 and faces the outer peripheral edge of the lock ring 58. ing. The lock ring 58 is formed in a sprocket shape by forming notches 59 at regular intervals on the outer peripheral edge of the lock ring 58. When the lock operation knob 67 is manually pulled outward, the lock shaft 65 slides to the left in FIG. 9, and the lock end 66 enters one of the notches 59 in the lock wheel 58 as shown in FIG. The rotation of the handle 55 and the power transmission mechanism is prevented. When the lock operation knob 67 is manually pushed inward, the lock end 66 comes out of the notch 59 of the lock wheel 58, and the handle 55 and the power transmission mechanism are rotated.

  A changeover switch 70 is attached to the handle support panel 50. The changeover switch 70 is a key switch that can be operated by inserting a specific key, and is configured such that energization of the solenoid 71 is turned on / off by the changeover operation of the changeover switch 70. The drive power for the solenoid 71 is supplied from a battery or other appropriate power supply device built in the shelf. The solenoid 71 has a plunger 72 protruding from its lower end, and a restriction plate 73 capable of restricting the movement of the lock shaft 65 is fixed to the plunger 72. When power is not supplied to the solenoid 71, the plunger 72 and the restriction plate 73 advance to the position closest to the rear of the lock shaft 65, and the lock end 66 of the lock shaft 65 enters one of the notches 59 of the lock wheel 58. To maintain. When power is supplied to the solenoid 71, the solenoid 71 sucks the plunger 72, retracts the regulating plate 73 upward from the slide range of the lock shaft 65, and manually pushes the lock operation knob 67 inward to lock the solenoid 71. The lock end 66 of the shaft 65 can be retracted from the notch 59 of the lock wheel 58.

  The lock shaft 65 having the lock operation knob 67 and the lock end portion 66, and the lock wheel 58 constitute a lock device that can lock the shelf so that it cannot move. The changeover switch 70 is for switching the shelf to be movable or fixed. When the changeover switch 70 is switched to the fixed side while the lock device locks the shelf so as not to move, the energization to the solenoid 71 is cut off, and the restriction plate 73 maintains the lock state by the lock device. When the changeover switch 70 is switched to the movable side, the solenoid 71 is energized, the plunger 72 is attracted by the solenoid 71, the restriction plate 73 escapes upward from the sliding range of the lock shaft 65, and the lock by the lock device is released. The shelf can function as a movable shelf.

  FIG. 11 shows the operation of the fourth embodiment. In FIG. 11, when the changeover switch 70 is turned on in step S60, the solenoid 71 is energized to be unlocked (S61). When the lock is released in step S62 and the rotation operation handle 55 is rotated in step S63, the shelf is driven in a direction corresponding to the direction of the rotation operation (S64). If the lock is not released in step S62, the process returns to step S60.

  When the shelf moves to the stop position (S65), the drive is stopped (S66), and the shelf waits for the shelf to be locked so as not to move (S67). The process proceeds to the determination step (S68). When the changeover switch 70 is turned off in step S68, as described with reference to FIGS. 9 and 10, the state in which the shelf is locked so as not to move by the locking device is maintained (S69). Further, even when the changeover switch 70 is not turned on and remains off in step S60, the state where the shelf is locked so as not to move by the locking device is maintained (S69).

  As described above, even in a shelf apparatus composed of a plurality of manual movement shelves, a lock device as shown in FIGS. 9 and 10 is incorporated in at least one manual movement shelf, and the operation as shown in FIG. 11 is performed. Thus, a shelf apparatus having a security function and a multi-passage function can be configured.

  It is already known to provide a locking device on a manual moving shelf. The fourth embodiment is different from a lock device in a known manual moving shelf in that a changeover switch 70, a solenoid 71, and a restriction plate 73 are provided. The solenoid 71 is provided as an actuator for restricting the lock device in the lock mode according to the change mode of the changeover switch 70 and releasing the lock mode. Therefore, the solenoid is not limited as long as it functions as an actuator, and for example, a motor, a fluid cylinder, or the like can be used.

  In the case where the technical idea according to the present invention is applied to the manual movement shelf described above, a lock device is provided instead of the brake device in the embodiment in which the technical idea according to the present invention is applied to the electric movement shelf described above. Yes.

  Moreover, you may apply the said locking device to an electrically-driven movable shelf. In the electric movable shelf device, if a drive current flows through the drive motor in a state where the at least one shelf is locked so as not to be moved by a mechanical lock device, the drive motor may be burned out. Therefore, in order to prevent a movement command signal from being transmitted from the adjacent shelf to the shelf that is locked so as not to be movable, communication from the adjacent shelf is blocked when the locking device is operating.

  The movable fixed shelf 100 described above is usually a fixed shelf, and can be temporarily handled as a movable shelf as needed. By using the movable fixed shelf 100 as one of a plurality of moving shelves constituting the moving shelf device, a security effect can be obtained as in the third embodiment. In addition, if a moving shelf device including a plurality of moving shelves is divided into several moving shelf groups by the movable fixed shelf 100, a multi-passage type moving shelf device can be configured. 12 to 15 show examples of various movable shelf devices using the movable fixed shelf 100 that can be switched to the fixed side or the movable side.

  FIG. 12 is an example of a multi-passage type electric moving shelf device, and shows an example of changing a multi-passage formation pattern in the order of (a) to (d). Nine electric moving shelves indicated by A to I are arranged, and fixed shelves are arranged on both sides of the electric moving shelves. Of the nine motorized mobile shelves, the motorized mobile shelves indicated by C and G are movable fixed shelves, divided into three groups of mobile shelves indicated by blocks 1 to 3 with these movable fixed shelves as a boundary. Yes. In FIG. 12 (a), in the block 1, work paths are formed between the moving shelves indicated by A and B, B and C, respectively, in the block 2, the moving shelves indicated by D and E, and between the moving shelves indicated by E and F, Work paths are formed between the movable shelves indicated by G and H, and between the movable shelves indicated by I and the fixed shelves, respectively. Numbers 1 to 6 are assigned to these work paths.

  FIGS. 12B, 12C, and 12D show a process of changing the layout of each moving shelf from the layout shown in FIG. 12A, and FIG. 12D shows the layout that has been changed. ing. As shown in FIG. 12B, the two movable fixed shelves indicated by C and G are moved toward the left and right, respectively. By the movement of the movable fixed shelf, the block 1 and the block 3 are narrowed and the block 2 is expanded. FIG. 12C shows a state in which the movable fixed shelf indicated by C is close to the movable shelf indicated by B, and the movable fixed shelf indicated by G is stopped close to the movable shelf indicated by H. FIG. 12D shows a state where the movable fixed shelves indicated by C and G are switched to the fixed side.

  Since the movable fixed shelf indicated by C and G is moved to the fixed side after being moved as described above, only one work path can be formed in the block 1 and the block 3, and four work paths are formed in the block 2. Can be formed. A movable shelf device composed of a plurality of movable shelves can change the formation layout of multiple work paths as necessary by moving the movable fixed shelves. By switching, the above layout can be maintained.

  FIG. 13 and FIG. 14 show an example of use of a movable shelf apparatus including a movable fixed shelf. Like the example of FIG. 12, it has the movement shelf shown by AI and the fixed shelf of both sides. The movable shelves indicated by C and G are movable fixed shelves. FIG. 13 is a movable shelf in which movable fixed shelves indicated by C and G are moved independently without being interlocked with each other and without being interlocked with other movable shelves and can be switched to fixed after the movement. Indicates the device. As described above, the movable shelf apparatus in which the movable fixed shelves indicated by C and G move in an interlocked manner can change the layout of a plurality of work paths as required, similarly to the example shown in FIG. Can be maintained.

  In the example shown in FIG. 14, the arrangement of the movable shelf, the movable fixed shelf, and the fixed shelf is the same as the arrangement in FIG. 13, but when the movable fixed shelf indicated by C and G is switched to the movable side, the movable fixed shelf is moved. The other moving shelves are configured to move in conjunction with each other. In the example shown in FIG. 14 (a), the movable shelves indicated by B, C, and D and the movable shelves indicated by F, G, and H converge, and between the leftmost fixed shelf and the movable shelf indicated by A, A and B Between the moving shelves indicated by D, E, between the moving shelves indicated by E, F, between the moving shelves indicated by H, I, and between the moving shelf indicated by I and the rightmost fixed shelf A work passage is formed in the front. When the movable fixed shelf indicated by C is moved to the left from this state, the movable shelf indicated by B that was close to the left side also moves in conjunction with the movable shelf, and stops when approaching the movable shelf indicated by A, A work path is formed between the movable shelves indicated by D. Similarly, when the movable fixed shelf indicated by G is moved toward the right side, the movable shelf indicated by H that was close to the right side also moves in conjunction with it, and stops when it approaches the movable shelf indicated by I, F , G are formed between the moving shelves. In this way, it can be operated in the same manner as a normal multi-passage type electric moving shelf device, and the formation form of a plurality of work passages can be arbitrarily changed.

  In the example shown in FIG. 15, all the movable shelves constituting the electric movable shelf apparatus are movable fixed shelves, and there are various types depending on whether the switch of each movable fixed shelf is switched to the movable side or the fixed side. It shows that it can be used. FIG. 15A shows an example in which all movable fixed shelves are switched to the fixed side. If all the movable fixed shelf changeover switches are switched to the movable side, it can be operated as an ordinary electric movable shelf device. If a part of the movable fixed shelf is switched to the fixed side and the other movable fixed shelf is switched to the movable side, it can be operated as a multi-passage type electric movable shelf apparatus. A security effect can be obtained by converging a plurality of movable fixed shelves and switching at least the outer movable fixed shelves to the fixed side.
