Description

[Detailed description of the invention] The present invention is a movable storage device, in particular, a pair of lifting devices consisting of a pair of upper and lower sprockets and an endless band stretched between these sprockets are placed facing each other, and The present invention relates to a mobile storage device in which a storage body is swingably supported on an endless band of the device via a support arm.

In conventional storage devices of this kind, in order to prevent the storage body from swinging inadvertently relative to the lifting device, for example, as schematically shown in FIG. A guide rail B having a U-shaped cross section and having a circular arc part _b1 and a straight part _b2 is arranged, and a swing prevention arm D is provided on the storage body C, and is attached to the free end of this swing prevention arm D. A guide roller E is configured to run along the guide rail B, and the swing preventing arm D and the guide rail B are used to prevent the storage body C from inadvertently swinging.

However, in the above structure, for example, when the swing preventing arm D is located at the arc portion _b1 of the guide rail B, the swing preventing arm D is prevented from swinging due to the swinging of the storage body C. Direction (Fig. 9
As the direction (X direction) approaches the length direction of the guide rail B, the rattling of the guide roller E with respect to the guide rail B gradually increases, and the storage body C swings by itself as shown by the imaginary line in FIG. There was a problem.

The present invention was devised in order to solve the above-mentioned problems associated with conventional devices of this type. Guide rails having the same shape as the locus of movement of the storage bodies are provided on the sides of each of the lifting devices, and these While displacing both guide rails in the vertical direction, rocking prevention arms extending to each of the guide rails are coupled to both sides of the storage body, and these rocking prevention arms are connected to each other.
The present invention is characterized in that guide rollers are disposed in opposite directions from the connection point with the storage body and run along the guide rail at the free end thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The mobile storage device according to the present invention will be described below based on embodiments shown in the drawings.

In the figure, 1a and 1b are a pair of upper and lower sprockets 11a, 12a and 11b, 12, respectively.
b and these sprockets 11a, 12a and 11
Endless link chain 1 stretched between b and 12b
3a and 13b, both of these lifting and lowering devices 1a and 1b are installed facing each other at a predetermined interval in the machine frame 10, and the lower sprockets 12 of both of these lifting and lowering devices 1a and 1b are installed oppositely at a predetermined interval.
a and 12b are interlocked and connected by a connecting shaft 14.

Reference numeral 2 denotes a drive motor for driving the lifting devices 1a and 1b, and a drive chain 2 includes a drive gear 21 provided on the drive shaft of the drive motor 2 and a driven gear 22 provided at the end of the connection shaft 14.
3, and by the operation of the drive motor 2, the roller chains 13a,
13b is rotated.

Further, 3, 3... are each of the link chains 13a,
A set of support arms 15a, 16 extending from 13b
It is a box-shaped storage body suspended freely between link chains 13a and 15b and 16b, and specifically connects the outer panel 17 and inner panel 18 of the link chains 13a and 13b, as shown in FIG. One end of the pin 19 is extended in the axial direction, and two support arms 15a and 16 are attached to the extended shaft portion 19a, respectively.
a, 15b, 16b are swingably mounted, and one of the support arms 15a, 15b and one of the adjacent support arms 16a, 16b form a pair, while pivots are provided on both sides of the storage body 3, respectively. 31
a, 31b are fixed, and a set of support arms 15a, 16a and 1
It is pivotally supported at the free ends of 5b and 16b.

Therefore, the storage bodies 3, 3... are both lifting and lowering devices 1.
Both link chains 13a, accompanying the drive of a, 1b,
By the rotation of 13b, the support arms 15a, 1
The lifting device 1 via 6a, 15b, 16b
It circulates around a and 1b in the vertical direction.

Therefore, the present invention provides guide rails 4a, 4b having the same shape as the locus of movement of the storage bodies 3, 3, etc. on the sides of each of the lifting devices 1a, 1b, and both guide rails 4a, 4b. are arranged to be displaced in the vertical direction, and rocking prevention arms 5a, 5b extending to the respective guide rails 4a, 4b are coupled to both sides of the storage body 3, so that the rocking prevention arms 5a, 5b are The free ends are arranged in opposite directions from the connection point with the storage body 3, and guide rollers 6a, 6b are provided at the free ends to run along the guide rails 4a, 4b.

That is, in the embodiment shown in the figure, the arcuate portions 41a, 41
a and 41b, 41b and the straight parts 42a, 42a and 42b, 4a, 42b, the lifting device 1a,
1b, and at a position where both rails 4a, 4b are displaced by a predetermined distance in the vertical direction, one end of the swing prevention arms 5a, 5b is fixed to the pivot shafts 31a, 31b fixed to the storage body 3, Both arms 5a and 5b are connected to the pivot shaft 31 on the free end side thereof.
They are arranged so as to extend in opposite directions from a and 31b.

Further, shafts 51a, 51b are provided at the free ends of these swing prevention arms 5a, 5b as shown in FIG. 5, and a set of guide rollers 6a,
A substrate 60 that rotatably supports 6a, 6b, and 6b.
is rotatably mounted, and both rollers 6 are mounted rotatably.
Guide rails 4a, 4 with a, 6a and 6b, 6b
b is held in between.

In the figure, 7, 7... are the lifting devices 1a, 1b.
A guide frame for guiding the link chains 13a, 13b, . . . is shown.

The present invention has the above-mentioned configuration, and the link chains 13a, 13b of both the lifting devices 1a, 1b are rotated by the operation of the drive motor 2, and the support arm 1 is attached to the link chains 13a, 13b.
The storage body 3 suspended via 5a, 16a and 15b, 16b also moves and lifts the lifting device 1.
It circulates around a and 1b in the vertical direction.

At this time, the storage body 3... tries to swing relative to the support arms 15a, 16a and 15b, 16b, but the two guide rails 4a, 4
b and both swing prevention arms 5a, 5b connecting the guide rails 4a, 4b and the storage body 3.
Accordingly, careless swinging of the housing 3 is reliably prevented.

That is, for example, as schematically shown in FIG.
When located in the straight portions 42a and 42b of b, both swing prevention arms 5 are prevented from swinging due to the swing of the storage body 3
The swinging directions of a and 5b are arrows X ₁ -X ₁ and X ₂ in Fig. 7.
As shown by _-
6a, 6b, 6b are the guide rails 4a, 4b.
Therefore, even if the storage body 3 attempts to swing carelessly at this position, it will be reliably blocked by the guide rails 4a, 4b and the swing prevention arms 5a, 5b. .

On the other hand, for example, as schematically shown in FIG.
4b, and the swinging direction of one swinging prevention arm 5a is as shown in FIG. 8 Y ₁ -Y ₁
Conventionally, when the direction is substantially along the length direction of the guide rail 4a as shown in FIG. However, in the present invention, the swing direction of the other swing prevention arm 5b is adjusted to the length of the guide rail 4b as shown by the arrow _Y2 - _Y2 in FIG. Since the direction is substantially perpendicular to the direction, the guide rollers 6b, 6b on the side of the swing prevention arm 5b hardly shake with respect to the guide rail 4b, and therefore, the storage body 3 is prevented from being accidentally moved. It never sways.

As described above, according to the mobile storage device according to the present invention, regardless of the moving position of the storage device with respect to the lifting device, both the swing prevention arms and the guide rails prevent the storage device from being inadvertently shaken. Since movement can be reliably prevented, objects to be stored can be stably stored in the storage body, and the safety of the entire device has also been improved.
