Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electric mobile shelf device.

[0002]

[Prior art]

 In a conventional mobile rack device in which a plurality of mobile racks are arranged so that the fixed racks can be moved in the left-right direction with the fixed rack as the back side, it is not electrically operated, so it can be used, for example, when moving a mobile rack. People had to push the moving shelf that they were trying to move to the side that was going to move it by hand, and this pushing force caused the moving shelf to move on the rails arranged on the base.

However, since such a manual-type movable rack device requires a required pushing force, it is difficult for a weak person such as a woman or a child to use it. Therefore, an electric moving rack device that moves the moving rack by a motor has been proposed for some time, but it was installed for that purpose from the beginning, and the drive motor was previously installed in the moving rack. However, it was not something that the user of a manual mobile shelving system could easily convert to a motorized existing manual mobile shelving system to make it easier to use.

[0004]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to solve the above-mentioned conventional problems and to provide an electric moving rack device that can be electrically operated by simply modifying the existing manual moving rack device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the invention of claim 1 is a mobile rack device in which a plurality of mobile racks are arranged so as to be movable in the left-right direction with a fixed rack as a rear side. A drive motor with a pinion gear is detachably installed so that the pinion gear faces the fixed shelf, and a common rack that meshes with the pinion gears of these motors is detachably installed on the fixed shelf. A switch is provided on each of the movable shelves, and when the motor is driven by this switch, the movable shelves move left and right with respect to the fixed shelves by rotating on the rack where the pinion gears mesh. It is characterized by being

According to a second aspect of the present invention, in the first aspect, a guide rail is detachably provided on an upper portion of the fixed shelf, and a guide member that is movably engaged with the guide rail when the movable shelf is moved is attached to the movable shelf. Detachable.

[0007]

[Embodiment of the invention]

 One embodiment of the present invention will be described with reference to the drawings. In FIGS. 1, 2, and 3, reference numeral 1 denotes an electric movable rack device, which comprises a fixed rack 2 and movable racks 3a and 3b arranged so as to be movable in the left-right direction with the fixed rack as the back side. The fixed shelves 2 have widths corresponding to the movable shelves 3a and 3b, respectively, and are installed side by side on the fixed shelf base 4. The movable shelves 3a and 3b are installed side by side on a movable shelf base 5, and can be moved via casters 7 on a rail 6 provided on the base. A drive motor 8 is installed above each of the movable shelves 3a and 3b. The motor 8 is detachably fixed to the upper surfaces of the movable shelves 3a and 3b by screws so that the motor shaft 9 projects toward the fixed shelf 2. A pinion gear 10 for driving is mounted on the motor shaft 9 with a key to prevent rotation.

On the other hand, a common rack 12 that meshes with the pinion gears 10 of the motors 8 is attached to the upper portion of the fixed shelf 2, and the bracket 13 is attached so that the pinion gears 10 mesh from the bottom. The bracket 13 is detachably screwed and fixed to the upper surface of the fixed shelf 2. Reference numeral 15 denotes a guide rail which is detachably screwed and fixed to the upper surface of the fixed shelf 2 together with the bracket 13. A guide member 16 detachably provided on the movable shelves 3a and 3b by the bracket 14 is movable on the guide rail 15. Engaged. As the guide member 16, for example, a guide roller is preferable, and although not shown, one guide roller is provided on each side of the movable shelves 3a and 3b.

Touch switches 18 and 19 for driving a motor are provided on both side surfaces of the movable shelves 3a and 3b. When the motor 8 is driven by these switches, the pinion gear 10 meshes with the rack 12 to rotate. Thus, the movable shelves 3a and 3b are moved in the left-right direction with respect to the fixed shelf 2. In this embodiment, the touch switch 18 on one side is a switch for moving the movable shelves 3a, 3b to the left, and the touch switch 19 on the other side is a switch for moving the movable shelves 3a, 3b to the right. It is a switch. The switches 18 and 19 also serve as operation switches for driving the motor 8 and safety stop switches. Reference numeral 20 is a control box containing a control circuit (not shown) for controlling the driving and stopping of the motor 8 by the switches 18 and 19.

Since it has the above-mentioned configuration, for example, when it is desired to see a document or the like in the fixed shelf 2 on the back side of the movable shelf 3b in FIG. 2, it is necessary to move the movable shelf 3b to the right side. At this time, the motor 8 is driven by the switch 19 of the movable shelf 3b, and the pinion gear 10 is rotated to move on the rack 12. As a result, the movable rack 3b is moved to the right side, and when it reaches a predetermined position as shown in FIG. 1, the drive of the motor 8 is stopped by a limit switch (not shown). As a result, the front of the fixed shelf 2 on the back surface of the movable shelf 3b is opened, and the documents and the like in it can be seen. In this way, by moving any of the movable shelves 3a, 3b in the left-right direction, the fixed shelf 2 on the rear surface can be used.

In the above, when the fixed shelf 2 and the movable shelves 3a and 3b are originally of the manual type, the following modifications are made to make them electrically driven. That is, a bracket 13 having a rack 12 is screwed and fixed to the upper portion of the fixed shelf 2 so as to be detachably installed, and a pinion gear 10 that meshes with the rack 12 is attached to the motor shaft 9 on the upper portions of the movable shelves 3a and 3b. Similarly, the motor 8 provided is screwed and fixed so as to be detachably installed. After that, touch switches 18 and 19 for driving the motor are provided on both side surfaces of the movable shelves 3a and 3b, and the switches 18 and 19 and the motor 8 are connected by electric wiring. As a result, the manual moving rack device becomes a simple electric moving rack device, and the same operation as described above can be performed.
