Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention moves a plurality of shelves arranged in parallel along the arrangement direction to form a working passage at a desired position between the shelves. The present invention relates to a moving rack device configured to be formed.

(Prior Art and its Problems) In the conventional shelving device, there is a moving shelving device in which a plurality of shelves are configured to be movable in order to effectively use the space. This moving rack device appropriately moves the racks arranged in parallel along the arrangement direction to form a working passage at a desired position between the racks only when necessary.
Usually, in such a moving rack device, a lighting device is attached to the entire ceiling surface to illuminate the entire device.

However, in such a configuration in which the lighting equipment is attached to the entire ceiling surface to illuminate the entire apparatus, the lighting equipment is not effectively used in a place where the working passage is not formed, and the number of lighting equipment is large. However, there was a problem that the cost increased.

Therefore, the movable rack device I, which can reduce the cost, is actually
-46588.

FIG. 5 shows a side view of the device I. As shown in the figure, five shelves 41 to 45 are arranged along the left-right direction. Of these, the shelves 41, 45 at both ends are fixed, respectively, and the remaining shelves 42, 43, 44 are arranged in parallel so as to be movable in the left-right direction. Further, a rail 46 is bridged between the upper portions of the shelves 41 and 45 at both ends, and a lighting device 47 that is movable along the longitudinal direction is attached to the rail 46.

In this movable shelf device I, for example, as shown in FIG. 5, when a working passage P is formed between the shelves 44 and 45, the lighting fixture 47 is moved above the working passage P, While illuminating only the working passage P, when the working passage P is formed between the shelves 41 and 42 as shown in FIG. 6, the lighting fixture 47 is moved above the working passage P. Then, only the work passage P is illuminated. In this way, since only one place where the work passage P is formed is illuminated by the single lighting fixture 47, the lighting fixtures 47 are effectively used, the number of lighting fixtures 47 is reduced, and the cost is reduced. It can be reduced.

However, it is necessary to fix the racks 41 and 45 at both ends because it is necessary to mount the rail 46 that supports the lighting fixture 47 so as to be movable between the racks 41 and 45. For this reason, the dimension between the shelves 41 and 45 is always constant, and when the movable shelving device I is not used, it is not possible to move all the shelves 41 to 45 to one side. There was a problem that became large.

On the other hand, FIG. 7 shows another conventional moving rack device II. As shown in the figure, in this movable rack device II, the parallel arrangement of 10
By appropriately moving the individual shelves 51-60, the shelves 51-60
A maximum of three work passages P can be formed between them. Further, one rail 64 is hung between the upper portions of the shelves 51, 60 at both ends, and three lighting fixtures 61, 62, 63 are movably mounted on the one rail 64, respectively. The luminaires 61, 62, 63 are moved onto the work passage P to illuminate the inside of the passage.

Also in this moving shelf device II, in the same manner as above, it is necessary to mount the rail 64, so that the shelves 51 and 60 at both ends must be fixed, respectively.
Since it is not possible to move all the shelves 51-60 to one side when not in use, the occupied space when not in use becomes large.

Further, in the movable rack device II in which a plurality of working passages P are formed in this way, for example, as shown in FIG. 7, a working passage P is formed between the shelves 53 and 54 and the second lighting is provided above the working passage P. Instrument 62
From the state in which the work passage P for two passages is formed between the shelves 56 and 57 and the third lighting fixture 63 is arranged above the work passage P, the work passage P is formed between the shelves 58 and 59. Even if formed, the inside of the passage cannot be illuminated.

That is, the second and third lighting fixtures 62 and 63 that illuminate the work passage P between the shelves 53 and 54 and between the shelves 56 and 57, respectively.
Are related to the workers working in the aisle,
It cannot be turned off, and of course it cannot be moved. On the other hand, the first lighting fixture 61 is the second and third lighting fixtures 6.
The rails 64 are blocked by the rails 2, 63 and cannot move up between the shelves 58, 59. When a plurality of working passages P are formed in this way, there is a problem that the inside of the passage may not be illuminated depending on the positional relationship of the lighting equipment.

(Object of the Invention) The present invention solves the above-mentioned problems of the prior art, reduces the cost, has a small occupied space when not in use, and forms a work passage when a plurality of work passages are formed. It is an object of the present invention to provide a moving shelf device that can always illuminate the inside of a passage regardless of the above.

(Means for Solving the Problem) According to the present invention, a plurality of shelves arranged in parallel are moved in the arrangement direction to form a working passage at a desired position between the shelves. In order to achieve the above-mentioned object, a moving shelf device is provided with two luminaires for illuminating a work passage formed adjacent to each other shelf among the plurality of shelves. Each is movably mounted so that it can be extended on either side of the shelf.

(Operation) In the moving shelf device of the present invention, every other shelf,
A lighting fixture for illuminating a work passage formed adjacent to the shelf is movably attached to both sides of the shelf so that the lighting fixture can be extended so that the lighting fixture is provided over the entire ceiling surface. The number of lighting fixtures decreases compared to installing,
Further, it is not necessary to dispose the rails for moving the lighting fixtures, and it is not necessary to fix the shelves at both ends. Moreover, when forming a plurality of work passages, both of the two lighting fixtures are placed on one side or the other side of the shelf. One of the two luminaires is projected to one side of the shelf, and the other luminaire is projected to the lower side of the shelf. It is possible to place lighting fixtures.

Further, a fluorescent lamp moving motor M2 shown in FIG. 4 for rotating and driving the supporting rods 12a and 12b is provided on every other shelf T, and the supporting rods 12a are driven by the driving of the fluorescent lamp moving motor M2. As shown in FIG. 3, the fluorescent lamps 13 and 12b rotate above the working passages P formed on both sides of every other shelf T, respectively.
The a and 13b are arranged so as to project.

FIG. 4 shows the above-mentioned motors M provided in this movable rack device III.
FIG. 3 is a block diagram of control circuits 100A and 100B for controlling driving of M1 and lighting of fluorescent lamps 11a and 11b. In the figure, a control circuit 100A including a shelf / moving direction determination circuit A and a first motor drive circuit B is provided commonly to all shelves t and T. The first motor drive circuit B is provided corresponding to the rack moving motor M1 of each rack t, T. Further, the shelves and the movement direction determination circuit A are configured to receive signals from the passage forming switches SW provided on the shelves t and T, respectively, and also provide drive commands to required first motor drive circuits B, respectively. Configured to give.

Then, for example, when the passage forming switch SW of the shelf number n is pressed, the shelf and movement direction determination circuit A determines the shelf to be moved and the movement direction thereof, and the first motor drive circuit B corresponding to the shelf to be moved. Is given a drive command including the moving direction, and the shelf moving motor M1 of the shelf to be moved is driven. Thus, the shelf with shelf number n, n + 1
A working passage P is formed between T and t.

Further, the control circuit B including the fluorescent lamp moving direction determination circuit C, the second motor drive circuit D, and the fluorescent lamp ON / OFF circuit E is provided with every other shelf T, that is, the shelf T to which the lighting fixtures 11a and 11b are attached.

Each fluorescent lamp moving direction determination circuit C
And each fluorescent lamp ON / OFF circuit E is configured to receive a signal from the passage forming switch SM provided in the corresponding shelf T, and is one smaller than the shelf number (n) of the corresponding shelf T. A signal is also taken in from the passage forming switch SM provided on the shelf t of number (n-1). Further, the fluorescent lamp moving direction determination circuit C is connected to each second motor drive circuit D, and each second motor drive circuit D is connected to each fluorescent lamp moving motor M2. The fluorescent lamp ON / OFF circuit E is connected to each of the corresponding fluorescent lamps 13a and 13b.

Then, for example, when the passage forming switch SW of the shelf T of the shelf number n is pressed to form the working passage P between the shelves T and t of the shelf numbers n and n + 1 as described above, the passage of the shelf number n is formed. In response to the pressing operation of the formation switch SW, the fluorescent lamp moving direction determination circuit C and the fluorescent lamp ON / OFF circuit E of the shelf are activated respectively, and the fluorescent lamps 13a and 13b attached to the shelf T of the shelf number n are on the right. The work passage P is swung in the direction to project above the work passage P, and the fluorescent lamps 13a and 13b are turned on to illuminate the work passage P.

When the passage forming switch SW of the shelf t of the shelf number n-1 is pressed, the work passage P is formed between the shelves t and T of the shelf numbers n-1 and n in the same manner as described above. Further, in response to the pressing operation of the passage forming switch SW of the shelf t of the shelf number n-1, the fluorescent lamp moving direction determination circuit C and the fluorescent lamp ON of the shelf T of the shelf number n on the right side are turned on.
/ OFF circuit E is activated respectively, and the fluorescent lamp on shelf T with shelf number n
Contrary to the above, 13a and 13b turn to the left to illuminate the inside of the work passage P.

Next, the operation of the movable rack device III will be described with a specific example. As shown in FIG. 2, when all the shelves t, T are moved to the left (converged state), when the passage forming switch SW of the shelving t having the shelving number 1 is pressed, the shelving T Each t is moved to the right by one passage (amount corresponding to the width dimension of the working passage P), and as shown in FIG.
A working passage P is formed between them. Further, the fluorescent lamps 13a and 13b of shelf number 2 are moved leftward to illuminate the inside of the working passage P.

Further, from this state, when the passage forming switch SW of the shelf T having the shelf number 4 is pushed, the shelves t and T having the shelf numbers 5 and above are moved to the right by one passage each, and the shelves are moved to the shelf as shown in FIG. A work passage P is also formed between the shelves T and t having the numbers 4 and 5. Furthermore, the fluorescent lamps 13a and 13b of the shelf T of the shelf number 4 swivel and move to the right,
The inside of the working passage P is illuminated.

Although not shown, when work passages P are formed on both sides of the shelf T to which the lighting fixtures 11a and 11b are attached, the fluorescent lamp 13a on one side is swung to the left to move to one side. While the working passage P is illuminated, the fluorescent lamp 13b on the other side is pivoted rightward to illuminate the working passage P on the other side.

Although not shown, each of the shelves t and T is provided with an emergency stop switch so that the movement of each of the shelves t and T can be stopped in an emergency.

According to this moving rack device III, since the lighting fixtures 11a and 11b are attached to every other shelf T, the number of lighting fixtures is smaller than that of mounting the lighting fixtures on the entire ceiling surface as in the moving rack device of the conventional example. Therefore, the cost can be reduced.
Further, unlike the movable shelving devices I and II of the conventional example, it is not necessary to dispose the rails for mounting the lighting fixtures, and the shelves t and T at both ends may not be fixed. Therefore, all the shelves t and T can be moved to one side when not in use, and the exclusive space when not in use is reduced. Furthermore, since the lighting fixtures 11a and 11b attached to every other shelf T can respectively illuminate the working passages P formed on both sides of the shelf T, when a plurality of working passages P are formed. There is no need to change the positions of the lighting fixtures 61, 62, 63 as in the above-described conventional moving rack device II, and regardless of the formation state of the work passage P, all work passages P are always Can be illuminated.

(Effects of the Invention) According to the moving shelf device of the present invention, the lighting equipment for illuminating the working passage formed adjacent to the shelf is provided on every other shelf on either side of the shelf. Since it is mounted so that it can be extended to the outside, the number of lighting fixtures is reduced, cost is reduced, and since it is not necessary to fix the shelves at both ends, all shelves can be placed on one side when not in use. It is possible to move it, the occupied space becomes small, and even when a plurality of work passages are formed, the inside of the passage can be illuminated regardless of the working passage formation state.
