Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to automatic storage of articles. Conventionally, a conveyor table is controlled to move along the front surface of a shelf on which articles are arranged side by side, and articles are automatically transferred between a desired storage position on the shelf and the conveyor table. Thus, automatic hangars are known that automatically take out and store articles.

In this case, it is usual to use a conveyance table device in which an article delivery device is provided on the conveyance table.

By the way, in this type of conventional conveyance platform device, the article to be conveyed is either placed on the conveyance platform naked or conveyed by being gripped by an article gripping device of an article delivery device. was. For this reason, shocks caused by unexpected accidents such as earthquakes,
There is a danger that objects being transported may fall due to equipment operation being stopped due to power outages, etc., or may be damaged by foreign objects falling from above.

An object of the present invention is to provide a transport platform device that prevents such dangers.

The present invention provides a transport platform device for an automatic hangar, in which a housing having an article storage chamber with only one end opened is provided on the transport platform, and an article delivery device of the transport platform device is connected between the storage chamber and the shelf. The casing is provided with spring-loaded article members so as to sandwich the stored articles from both sides, so that when the articles are transferred, A solenoid is provided to release the article from being held by the article gripping member, thereby preventing the article on the conveyor from falling or colliding with an external object. A delivery device is provided inside the casing, and the casing is rotatable so that the direction of its opening can be changed, thereby allowing goods to be delivered selectively in various directions. It is becoming more and more like this.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

FIG. 1 is a schematic top view for explaining the outline of an automatic hangar. Referring to the figure, the automatic hangar consists of a storage shelf 1 for storing articles, a transport platform 2 that moves along the front of the storage shelf 1, and a transport platform 2 that moves along the front surface of the storage shelf 1. It has an article transfer device 3 on the stand 2 for transferring articles between the storage shelf 1 and the conveyor table 2, and the article is transferred from any storage position of the storage shelf 1 to the article handling port 4. The removal of the articles from the article handling port 4 and the storage of the articles into a desired storage position on the storage shelf 1 are automatically performed.
Various methods are known as control methods for controlling the transport platform 2 and the article delivery device.

Various methods are used as transfer devices, such as a hook method in which the article is hung on a hook, an electromagnetic method in which the article is attracted by an electromagnet, a clamping method in which the article is held between clamping members, and a vacuum suction method.

By the way, in conventional conveyance table devices, no matter what type of delivery device is used, the articles being conveyed are maintained in a state exposed to the outside. For example, the articles may be placed on an article mounting table on a conveyor table and conveyed, or they may be conveyed without being placed on the table at all and merely gripped by an article gripping device of an article delivery device.

In these cases, for example, if an object falls from above, the object being transported is damaged, the object falls due to an impact such as an earthquake, or the object gripping device stops operating due to a power outage, etc. Similarly, there is a risk that objects being transported may fall.

In order to prevent these dangers, the conveyance table device according to the present invention includes a casing having an article storage chamber on the conveyance table.

With reference to the external perspective view of the embodiment shown in FIG.
The carrier 2 is constituted by an L-shaped platform, which is installed, for example, in a controlled manner up and down on a moving column which is controlled to move in the horizontal direction, so that it can be moved along the front surface of the shelf. It is now movable.

An arm 23 is provided on the vertical part 21 of the conveyance table 2 so as to project above the horizontal part 22, and between this arm 23 and the horizontal part 22, a casing 24 is rotatable in a horizontal plane. is supported by In Figure 2,
A pivot pin 25 is shown for attachment to arm 23.

The housing 24 defines a chamber open at one end, which provides a chamber for accommodating articles, through which the articles are inserted and removed.

The article delivery means may be any of the methods described above, as long as it is provided so that the article can be taken in and out through the opening 241, but in this embodiment, vacuum suction is used, as will be explained in detail with reference to FIG. A structure including a suction head is provided inside the housing 24 so as to be movable between the opening 241 and the opposite end thereof. In FIG. 2, the suction head arrangement is indicated by the dotted line 3.

In this embodiment, the article is shown as, for example, a magnetic tape (wound on a reel) 10.

According to this structure, the conveyance table 2 is positioned at a desired storage position on the shelf, the suction head assembly 3 comes out from the opening 241 to suction the article on the shelf, and is reversely moved to the depths inside the casing 24. By returning, article 10
is housed in the housing 24.

When discharging an article stored in the housing 24 to a shelf or a handling opening (FIG. 1, 4), the suction head assembly 3 pushes out the article 10 to the outside of the opening 241 while adsorbing it. When it moves to the shelf or the handling opening, the suction force is released, and then it reverses and returns to the back of the casing 24. In this way, when the article is on the conveyor table, it is housed in the housing 24 and protected from the outside, so there is no risk of contact or collision with external objects, and there is no risk of falling from the conveyor table. reduced. Note that, as will be described later, if an article gripping device is employed inside the casing, the risk of falling can be further eliminated.

In this embodiment, the casing 24 is rotatable, and the article delivery device is connected to the casing 24.
By rotating the housing and changing the direction of the opening 241, articles can be taken in and out from various directions. 4) has the advantage of having a degree of freedom in arrangement.

FIG. 3 is a perspective view with main parts cut away to show the internal structure of the casing 24.
The suction head assembly 3 includes a slider block 31 that is movably installed inside the casing between an opening and the opposite end, and a suction head 32 that is installed on the slider block. There is.

The slider block 31 is slidably installed on a guide rod 33 installed within the housing so as to extend in the direction of movement of the slider block, and is thereby guided in its movement. Note that both ends of the guide rod are fixed to the inner wall of the casing, but the casing wall is shown broken in the figure, so the fixing structure is omitted.

Further, the slider block 31 is connected to a chain 34, which is connected to the housing 24 via pulleys 35 and 35' attached to the inner wall of the opening side of the housing 24 and the opposite side, respectively. Gear 3 driven by installed motor 36
It meshes with 7. As a result, the rotation of the motor 36 moves the suction head assembly back and forth. Note that 38 and 38' are tension rollers that absorb slack in the chain.

The slider block 31 has an arm 311 on which a suction head 32 is attached, which arm is pivoted on a pin 312 for slight rotation in a vertical plane and has a front end as shown. A suction head 32 is attached, and this suction head 3
A suction pipe 313 leading to the arm 311 is led out from the rear of the arm 311 and connected to a pump (not shown).

At the front of the upper end of the arm 311, an article (see FIG.
10) has a support pad 314 for receiving a part of the end wall of the article to ensure stable support of the article when the article is suctioned by the suction head 32.

Further, the slider block 31 has a tapered arm 315 extending in front of the suction head 32 and its support arm 311, the tip of which forms a downwardly inclined surface. has been done. This tapered arm 315 is designed so that when the suction head assembly 3 comes closest to the opening of the housing, the tip of the tapered arm 315 enters into the shelf, goes under the article, and lifts up the article. It's starting to work.

The arm 311 is provided with article guide plates 316 and 316' projecting forward on both sides of the mounting portion of the suction head 32.

The housing 24 is further provided with an article gripping device for firmly holding the article housed in the housing 24. That is, levers 243 and 243' are pivotally supported on frames 242 and 242' provided on both sides of the article storage space of the housing 24. One end of each lever has pads 244, 24.
4' is provided, and the other end is provided with both pads 24.
4 and 244' are tension-biased by springs 245 and 245' so as to approach each other and clamp the article therebetween.

Deep inside the housing 24, a solenoid 246 is provided on the inner wall, and the rod 24 is connected to the plunger.
7, 247' are connected to levers 243, 243', respectively. Rods 247, 247' and lever 2
43,243' is connected to the lever 243,243'.
When the solenoid 246 is energized, the spring 2
