Description

DETAILED DESCRIPTION OF THE INVENTION For example, in an article storage device in the form of a three-dimensional automatic warehouse in which parts or documents, etc. are placed in boxes and carried in and out of three-dimensional shelves using a stacker-type conveyor, In order to carry out loading and unloading easily and smoothly, it is desirable that there is little friction between the bottom surface of the box and the support surface of the shelf and the lifting platform support surface of the carrier.

However, when a horizontal force such as an earthquake is applied, if the friction is small, there is a risk that the boxes stored on the shelf may slip and protrude toward the passageway of the conveyor, or fall from the shelf into the passageway. It was warm enough.

In addition, in order to prevent boxes from protruding into the aisle or falling, there were shelves that were tilted downward from the front to the back, but this angle of inclination was small;
Furthermore, there was no such device that used a conveyor to carry articles into and out of the shelves.

The present invention relates to an improvement of an article storage device that overcomes such difficulties, and is an article storage device in which stored articles can be carried in and out using a stacker-type conveyor on a shelf in which a large number of shelf booths are arranged vertically and horizontally. In the device, the shelf booth is inclined downward from the shelf frontage toward the back of the shelf booth, and a locking piece is provided at an end of the stored object;
The stacker-type conveyor is equipped with a loading platform that can move up and down while oriented in the horizontal direction, and the loading platform has a support member that can slidably support the stored items, and the loading platform has a support member that can slideably support the stored items. An engaging member is provided on the supporting member so as to be tiltable along the vertical arrangement surface of the shelf booths between the lines, and an engaging member is provided on the supporting member so as to be movable along the longitudinal direction of the supporting member. It is configured such that it can be detachably engaged with the locking piece to allow the stored object to be carried out from the shelf booth or carried into the same shelf booth along the extension line of the shelf booth. Its purpose is to provide an article storage device that is safe and does not cause stored items to protrude or fall even in the event of an earthquake and the like, and that saves labor in carrying in and out of articles.

As described above, the present invention provides an article storage device in which stored items can be carried in and out of a shelf in which a large number of shelf spaces are arranged in the vertical direction using a stacker type conveyor, in which the shelf spaces are arranged from the shelf frontage to the shelf. Since the booth is tilted downward toward the back of the booth, even if an external force such as an earthquake is applied, the items stored in each shelf booth will be stored in the innermost part of each shelf booth by gravity. The stored items are prevented from protruding from the shelves or falling into the passage, and are extremely safe.

Further, in the present invention, the stacker-type conveyor is provided with a loading platform that can be raised and lowered vertically, and the loading platform is provided with a loading platform that extends between a horizontal line and an extension line of the shelf booths along the vertical arrangement surface of the shelf booths. A support member capable of supporting the stored object is provided so as to be tiltable along the vertical arrangement surface of the shelf, and the support member is detachably engaged with the stored object along the extension line of the shelf booth to move the stored object from the same shelf booth. Since the engaging member for carrying in and out the stored articles is provided, the articles stored in the inclined shelf booth can be smoothly carried out, and the stored articles can be easily carried into the inclined shelf booth. I can do it.

Hereinafter, one embodiment of the present invention illustrated in FIGS. 1 to 4 will be explained. Reference numeral 1 denotes a three-dimensional shelf in which a large number of shelf booths 2 are provided vertically and horizontally, and the shelf booths 2 are A vertical column 3 and a container support member 4 tilted downward from the front to the back.
A stopper 9 is fixed near the rear end of the container support member 4, and a stopper 9 is fixed to the bottom and top of each shelf passage 6 formed between the opposing shelf openings 5 of the three-dimensional shelf 1. Running rails and running guide rails (not shown) are laid oriented in the longitudinal direction.

Further, a stacker type crane 10 serving as a carrier is placed on the traveling rail so that it can travel in the shelf passage 6 along the rail and carry containers 20 in and out of the shelf booth 2. , is engaged with the traveling guide rail.

The Statzker type crane 10, like a normal Statzker type crane, has a main frame 11 that is extended until it approaches the rail and has a built-in traveling drive device (not shown), and a main frame 11 that is extended to approach the rail and has a main frame 11 that can be moved up and down. 11 and a loading platform 12 provided thereon.

Container 20 is placed in shelf booth 2 of such three-dimensional shelf 1.
As shown in FIG. 4, cranks 1 rotated by a drive motor 14 are installed at both ends of the loading platform 12 of the stacker crane 10.
5, both ends of the lift table 17 corresponding to the supporting members of the component of claim 1 are attached to the crank 15 via levers 16, and a guide 18 protrudes downward from the center of the lift table 17. Guide rollers 19 are placed on the loading platform 12 so as to sandwich the
It is pivotally connected.

Further, the lift table 17 has a container 20
A hook 13 (corresponding to the engaging member in the claims) is provided which engages with the front locking piece 22 to pull the container 20 forward or push it backward.

Since the embodiments shown in FIGS. 1 to 4 are configured as described above, horizontal forces such as those caused by earthquakes act on the containers 20 stored in the respective shelf booths 2 and supported by the container support members 4. Even if the container support member 4 is tilted, the container 20 on the support member 4 is firmly and stably held in each of the shelf booths 2, and protrudes into the shelf passage 6 sandwiched between the opposing shelf booths 2. Otherwise, there is no risk of the item falling from the shelf booth 2 onto the floor within the shelf passageway 6.

In addition, in order to carry the container 20 out of the required shelf space 2 or into the required shelf space 2, the drive motor 14 on the opposite side of the shelf space 2 is driven to move the lift table 17 to the required shelf space 2. By tilting the container 20 toward the container 20, engaging the hook 13 with the container locking piece 22 of the container 20, and then moving the hook 13, the container 20 can be carried in and out with great ease.

In the embodiment shown in FIGS. 1-4, the lift table 17 is
Although the lift table 17 is tilted, other link mechanisms, gear mechanisms, etc. may be used to tilt the lift table 17.

Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to such embodiments, and that various design modifications can be made without departing from the spirit of the present invention. be.
