DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load shelving device for a flow shelf, wherein a load is slidably supported downward by a wheel rail.

[0002]

2. Description of the Related Art In a fluidized shelf, a load supplied to an upper end of a wheel rail is slid downward on the wheel rail by gravity and received by a stopper provided near a lower end of the wheel rail. A load replenished on a wheel rail on which no load is supported is to be slid over the entire length of the wheel rail. The impact when it is done is also large. The impact at this time becomes larger as the overall length of the wheel rail is longer and as the inclination angle is larger.

[0003] Therefore, in a fluidizing shelf in which the entire length of the wheel rail is long or the inclination angle is set to a large value, depending on the load to be handled, the load easily collapses or falls due to the impact when received by the stopper. Therefore, it is necessary to automatically apply a braking force at the lower end of the slope to smoothly stop the load sliding down the slope while giving the wheel rail the required length and the required angle of inclination.

As described in Japanese Utility Model Publication No. 22485/1993, this type of load shelving device for a flow shelf has an inclined brake plate on which a slidable load rides on the inclined lower end of a wheel rail. Brake plate type, real fair 2
As described in Japanese Unexamined Patent Application Publication No. -6001, a braking belt system in which an endless braking belt is stretched over a plurality of wheels constituting a wheel rail,
As described in JP-A-6-10828, there is known a friction plate system in which a friction plate is provided beside a wheel rail.

[0005]

However, it is practically impossible to adjust the braking force according to the weight of the load to be handled by a conventional load braking device of the inclined braking plate type or the friction plate type. Although it is theoretically possible to adjust the braking force on the load by changing the initial load applied to the braking belt in the load braking device of the braking belt type, the adjustment method is not practical and the structure is complicated. This leads to a significant cost increase.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a wheel rail used in a fluidized shelf, and 2 denotes an inclined lower end of the wheel rail 1. The shelf frame 3 to be supported is a picking work apron (work table) which is attached as needed. As is well known in the art, the wheel rails 1 are generally arranged in a horizontal direction with a pair of left and right units so that one load W is supported by two rows of left and right wheel rails 1. Also, it is common to arrange them in upper and lower stages.

As shown in FIG. 2, the wheel rails 1 are provided with wheels 5 at equal intervals in the longitudinal direction of the frame 4 in a groove 4 having a vertical cross section, and a part of each wheel 5 It is supported by a horizontal support shaft 6 so as to protrude upward.

Reference numeral 10 denotes a wheel cover which constitutes a load braking device. The wheel cover 10 is made of an elastic material such as stainless steel and has a width substantially equal to the width of the wheel 5.
One wheel 5 is bent into a substantially C-shape so that it can be held by elasticity, and has both ends 11a, 1a.
Bent portions 12a and 12b are formed inside 1b to make the interval narrower than the diameter of the wheel 5.

The wheel cover 10 has two bent portions 12.
By strongly pressing down the a and 12b on the wheel 5, the bent portions 12a and 12b once spread against the elasticity, and return elastically after passing below the axial level of the wheel 5, As shown by the solid line in FIG.
Can be fitted. At this time, both ends 11a and 11b of the wheel cover 10 are connected to the bottom plate 4 of the frame 4.
a, and the wheel cover 10 is close to the wheel 5
To prevent the unit from rotating together. Further, an appropriate tool (for example, the tip of a flathead screwdriver) is inserted between one of both end portions 11a and 11b of the wheel cover 10 and the frame bottom plate 4a, and an operation is performed such that one end of the wheel cover 10 is pushed up and the like. 5, the wheel cover 10 can be removed.

The wheel cover 10 which can be detachably fitted to the wheel 5 as described above has a structure shown in FIG.
As shown in (1), the wheel rail 1 is fitted to one or a plurality of selected wheels 5 within an appropriate length region of the inclined lower end portion. As a result, the wheel 5 to which the wheel cover 10 is fitted does not function as a wheel, and the load W sliding on the wheel 5 slides on the wheel cover 10 in a fixed state against friction to move. At this time, the frictional force between the wheel cover 10 and the load W acts as a braking force, and the sliding speed of the load W is reduced.

Therefore, by taking into account the number and arrangement pattern of the wheel covers 10 used for one wheel rail 1, the load W sliding on the wheel rail 1 inclining downward is smoothly decelerated, and The rail 1 can be stopped smoothly immediately before colliding with the stopper 13 provided near the lower end of the rail 1. Although the stopper 13 is illustrated as being integrally connected to the shelf frame 2, the stopper 13 may be detachable from the shelf frame 2, or in particular, the picking work apron 3 may be attached thereto. If there is, load W in front of this apron 3
The stopper 13 can be eliminated by disposing the wheel cover 10 so as to stop smoothly.

As shown in FIG. 4, a wheel cover 14 having a length capable of simultaneously covering a plurality of wheels (two in the illustrated example, but the number is not limited) may be provided. In this case, the wheel cover 14 is provided with wheels 5 at both ends of the area covered by the wheel cover 14.
The bent portions 15a, 15b at both ends of the wheel cover 14
Is elastically pressed and attached below the wheel axis level. One or a plurality of the wheel covers 14 may be used to form a braking device. However, the braking device may be formed by combining the wheel cover 14 and the wheel cover 10 described in the above embodiment. .

[0015]

As described above, the load braking device of the present invention is obtained by simply bending an elastic band-shaped plate into a substantially C shape.
One wheel cover that is extremely simple in structure and can be constructed at low cost
One or more wheels, depending on the overall length and inclination angle of the wheel rails, the weight of the load to be handled, etc., or one or more selected wheels on the wheel rails. By simply fitting against the elasticity, it is possible to apply the necessary braking force to the load sliding on the wheel rail inclining downward and decelerate it. Therefore, the load can be smoothly stopped at the inclined lower end of the wheel rail without impact,
There is no need to cause inconveniences such as collapse of the cargo or collapse of the cargo.

In addition, compared with the case where a friction plate instead of a wheel cover is mounted on the wheel rail frame or the side of the wheel rail, the mounting means is not required, and the mounting and dismounting work can be performed very easily and inexpensively. be able to. Of course, it is very easy and easy to change the number and arrangement pattern of the wheel covers to be used, so if the load to be handled changes, the number and arrangement pattern of the wheel covers to be used according to the weight of the load, etc. By changing the braking force, the braking force can be adjusted and the intended purpose can always be reliably achieved.

According to the second aspect of the present invention, 1
Since one wheel cover can be fitted to one wheel, it is possible to finely adjust the braking force,
According to the configuration of the third aspect, the wheel cover can be easily attached and detached, and a large braking force can be obtained by one wheel cover.
