Description

[Detailed description of the invention] (Industrial application field) The present invention has a roller rail in which load-supporting rollers are fitted and supported at appropriate intervals in the length direction of the rail material, so that the roller rail is tilted downward from the storage side to the storage side. This relates to a stopper that brakes and stops sliding cargo at the exit side end of a floating shelf installed in the warehouse.

(Problems to be solved by conventional techniques and ideas) In conventional fluidized shelves of this type, for example,
As described in Japanese Patent No. 102629, a sliding load is stopped by colliding with a rising plate portion of a support frame member that supports the exit side end portion of the roller rail.

In such a conventional structure, a shock is given to the load due to a collision with the rising plate portion of the support frame material, so that it is not possible to handle a load that easily collapses.

In order to solve these problems, for example, as described in Japanese Utility Model Publication No. 44-24248,
It has been considered to use a braking plate that is inclined so that sliding loads can ride on it as a stopper, but the conventional braking plate is attached to the frame material installed at the exit side end of the roller rail. The side ends were fixed with bolts and nuts, and the storage side end of the brake plate was a free end.

In such a conventional configuration, not only is it time-consuming to install the brake plate, but also it is difficult to install the brake plate from the loading start position (position near the free end) to the fixed end (output side end) of the brake plate. ) is large, a very large downward bending force acts on the fixed end of the brake plate, and the fixed end of the brake plate is likely to be damaged. Therefore, in such a configuration, it is necessary to attach the fixed end (exit side end) of the brake plate via an elastic body such as hard rubber, which inevitably increases the cost considerably.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention has been developed by extending a suitable length from the exit side end of the roller rail, as shown in the attached illustrative diagram. Rail portion 13 that does not support the load supporting rollers
A stopper 18 for braking and stopping the load is provided on this rail portion 13, and the stopper 18 extends from the input side end lower than the support level of the roller rail to the output side end higher than the support level. A braking plate 14 extending to the side end, a fitting member 15 fixed to the entry side end of the braking plate 14 and fitting into the rail portion 13 so as to be able to slide only in the longitudinal direction of the rail material, and the braking plate 14 It is composed of a stopper part 16 that projects upward from the exit side end of the plate 14, and a vertical plate part 17 that extends downward from the exit side end of the braking plate 14, and the vertical plate part 17 is A stopper on the exit side of a fluid shelf is proposed, which is made of abutting the inner end 11a of the upper cover plate portion 11 of the support frame member 7a supporting the exit side end of the roller rail to prevent movement in the exit direction. It is.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a shelf frame, and shelf units 2 are installed on this shelf frame 1 in a plurality of upper and lower stages. Each shelf unit 2 is composed of a support frame 3 having a rectangular planar shape whose left and right sides are fixed to the shelf frame 1, and a roller rail 4. A pair of side frame members 5a, 5b, and an intermediate support frame member 6 (third
5) and a pair of front and rear support frames 7a, 7b that are installed between the ends of the both side frame members 5a, 5b and support both ends of the roller rail 4, and the roller rail 4 are installed in multiple rows in the left and right lateral directions so that one load is supported by two adjacent roller rails 4.

As shown in FIGS. 3 to 5, the roller rail 4 has a rail material 8 which has a groove-shaped cross section and has outwardly folded overhangs 8a on both shoulders. The shafts are fitted and supported at appropriate intervals in the width direction. Further, the delivery side support frame material 7a of the support frame 3 has an upper cover plate part 11 connected to the front edge of the lower receiving plate part 10, and the upper cover plate part 11 is vertically connected to the front edge of the lower receiving plate part 10. Rail material positioning recesses 12 into which the upper portions of the rail materials 8 fit are formed at appropriate intervals in the downward inner end portion 11a. The storage side support frame material 7b of the support frame 3 is also basically the same as the support frame material 7a.
is the same as

The roller rail 4 is provided with a rail portion 13 over an appropriate length from the exit side end where the load supporting roller 9 is not supported, and a load braking stopper 18 is disposed on this rail portion 13. It is set up. The stopper 18 is located at the warehousing side end 1 that is lower than the support level of the roller rail 4.
4a to the exit side end 1 higher than the support level.
4b, and below the storage side end 14a of the brake plate 14,
A fitting member 15 is fixed to both shoulder projecting portions 8a of the rail portion 13 so as to be able to slide only in the longitudinal direction of the rail material, and a fitting member 15 is fixed to the delivery side end 14b of the brake plate 14, and a fitting member 15 is fixed to the shoulder projecting portion 8a of the rail portion 13. The stopper part 16 and the vertical plate part 17 extending downward are integrally formed by bending.

The load braking stopper 18 is assembled to each roller rail 4 before each roller rail 4 is installed on the support frame 3. That is, the fitting member 15 is fitted and slid onto the rail material 8 of the roller rail 4 from the exit side end, and the vertical plate portion 17 is loosely fitted into the groove portion of the rail material 8. After this, both ends of the roller rail 4 (both ends of the rail material 8) are attached to a pair of front and rear support frame members 7a, 7b in the support frame 3.
The shelf unit 2 is assembled by being fitted and supported in a predetermined position as is well known in the art, and the shelf unit 2 is supported by the shelf frame 1 so that each roller rail 4 is inclined downward from the storage side to the exit side.

The fluid shelf is assembled as described above, but
Vertical plate portion 1 of stopper 18 for braking and stopping loads assembled on the exit side end of each roller rail 4
7 is in contact with the inner end 11a of the upper cover plate portion 11 of the support frame member 7a, and is prevented from moving in the exit direction (inclination downward), and the lower end of the vertical plate portion 17 is connected to the rail member. It is abutted and supported on the inner bottom surface 8b of 8.

When the load 19 is placed on the entry side end (slanted upper end) of the roller rail 4 so as to straddle two adjacent roller rails 4, gravity causes the load 19 to tilt downward on the load supporting roller 9. slide to the third
As shown by the imaginary line in the figure, it moves onto the braking plate 14 of the stopper 18 for braking and stopping the load. However, while sliding on the plate 14, the load 19 is moved due to the frictional resistance between the plate 14 and the load 19.
The sliding speed of 9 is reduced, and the stopper part 1 is moved at low speed.
6 or stops before the stopper portion 16. A subsequent load 19 that has been stored in the same way collides with the previously stopped load 19 and comes to a stop, but since the sliding distance is shortened, it does not receive a large impact.

During unloading work, the stopper 18 for braking and stopping the load is used.
The first load 19, which is stopped at the top, is taken out of the warehouse.
However, when the leading load 19 is picked up, all of the following stopped loads 19 slide downward on an incline due to gravity, and a front-stuffing action is performed, so that the leading load 19 is always
9 stands by on the stopper 18 for braking and stopping the load.

In addition, the vertical plate portion 1 of the load braking stopper 18
When the horizontal width of the vertical plate 7 is formed to be larger than the maximum width of the rail material 8, a cutout recess into which the rail material 8 fits is formed from the lower end of the vertical plate 17, thereby forming the lower end of the vertical plate 17. can also be brought into contact with the rail receiving surface 10a of the lower receiving plate portion 10 of the support frame member 7a on both the left and right sides of the rail member 8.

(Operations and Effects of the Invention) As described above, the stopper on the exit side of the fluidized shelf of the present invention causes the load sliding on the roller rail to ride on the braking plate and decelerate it.
The shock when the brake plate collides with the stopper at the end of the brake plate is extremely small, and even a load that easily collapses can be handled safely.The greatest effect of this invention is as follows.

That is, the braking plate fits the fitting member fixed to the end on the storage side into the rail portion of the roller rail that does not pivotally support the load supporting roller, and uses the fitting member to By sliding the braking plate in the length direction of the roller rail, the vertical plate part at the exit side end is brought into contact with the inner end of the upper cover plate part of the support frame that supports the exit side end of the roller rail. By making contact with it, it is possible to set it correctly in a predetermined position on the roller rail.

Therefore, the time-consuming installation work using conventional bolts and nuts is unnecessary, and the braking plate can be installed easily and efficiently.
Furthermore, since there is no need to form mounting holes for the braking plate on the roller rail side, there is no fear that the strength of the roller rail will be reduced due to drilling.

Furthermore, since the warehousing side end of the braking plate, which is the starting position for running onto the load, is supported by the roller rail via the fitting member, when the load runs on the braking plate, the braking plate will The downward bending force that acts on the fixed portion of the brake plate and the fitting member is small, so even if the braking plate and the fitting member are simply rigidly connected by welding or the like, there is almost no risk of breakage. In other words, there is no need to interpose a buffering elastic body at the attachment point of the braking plate, and it can be implemented at low cost.
