DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage table used, for example, for storing rolls for a rolling mill.

[0002]

2. Description of the Related Art Generally, when storing roll-shaped products in a stack, it is necessary to mount a spacer serving as a cushion material between the rolls. There are two types of methods for mounting the spacer, an automatic type in which a mounting and dismounting mechanism is added to the roll holding frame, and a manual type in which mounting and dismounting is performed manually using only the holding frame.

On the other hand, roll storage tables are often handled as ancillary devices of various facilities, and in many cases, they are installed not in a single unit but in multiple units. Therefore, it is required that the cost is low and the installation space is as small as possible. You. Under these circumstances, the automatic type in the prior art has a poor operation reliability of the spacer mounting / removing mechanism, and the rolls can be overlapped up to a two-stage stack, and there is no application development.

[0004] In order to multiply the stack, it is necessary to add a power unit, which complicates the mechanism, increases the maintenance cost, and requires a large amount of cost. There are drawbacks that cannot be provided. Therefore, when storing a fixed number of rolls, a wider installation space is required as compared with a two -stack type.

Further, the manual type has a disadvantage in that it is not labor-saving and the work efficiency cannot be improved, and also from the viewpoint of work safety. For example, "roll storage table" (Japanese Utility Model Application Laid-open No. 63-1141)
No. 0) or “roll storage device for rolling” (Japanese Utility Model Application
No. 2507), but these still have the above-mentioned problems.

[0006]

According to the present invention, a spacer is automatically provided between each roll of a multi-stacked roll by a simple mechanism using a roll raising / lowering action force at the time of roll loading / unloading as a power source without a power unit. It can be installed and removed, satisfying the function as a multi-stage roll storage table, improving work efficiency by labor saving,
It is another object of the present invention to provide a roll storage table capable of significantly reducing the installation space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a holding frame having a structure in which four pillars are assembled on a square formwork as a base, and upper and lower parts of two pillars parallel to a storage roll body length direction are connected by a reinforcing material. Cushioning members 2 and 2 'for preventing the occurrence of roll damage flaws are uniformly attached to the four surfaces of the pillar contacting the roll body and the two bottom surfaces for holding the lowermost roll.

A lower lever 6 and an upper lever 13 for automatically mounting and dismounting a spacer between the rolls are arranged on one of both side surfaces of the holding frame 1 where the roll body contacts, so as to be lowered in a direction perpendicular to the roll body length direction. I do. The lower lever 6 is fixedly attached to both ends of the rotating shaft 4 held by lower lever shaft bearings 5 and 5 '.
Is a rotating structure.

At the tip of the lower lever 6, a lower spacer 7 having a lower suspension bar 8 attached thereto is held by a lower spacer support shaft 9 and is rotatable. The lower lever 6 can be rotated clockwise (hereinafter, clockwise and counterclockwise). Clockwise is for each drawing
Rotation in a is) direction has a tip of the lower suspension bar 8 can be suspended to the horizontal axis of the lower suspension bracket 10. The upper lever 13 is attached to the upper lever shaft 12 held by the upper lever shaft bearings 11 and 11 'on the gantry 3 provided on the reinforcing member of the holding frame 1, and the distal end is provided with the upper spacer in the same manner as the lower lever 6. 14, the upper suspension bar 15 and the upper spacer support shaft 16 are attached, and when it is lowered, the upper suspension bar 15 is moved to the upper suspension bracket 17.
The structure can be suspended on the horizontal axis.

A dummy arm 19, a link arm 20, a torsion spring 21, and a spring retainer 22 are fitted into a substantially intermediate portion of the rotary shaft 4, and the dummy arm 19 has a mounting angle of the lower lever 6 with respect to the rotary shaft 4. It is fixed at substantially the same angle, is independent of the link arm 20, and has a structure in which force is transmitted to the link arm via the dummy arm 19 and the projecting piece 29 attached to the dummy arm 19.

The link arm 20 and the rotating shaft 4 are loosely engaged with each other, and are connected to the lifting rod 25 and link pins 24 and 24 'via links 23. The elevating rod 25 is a cylindrical guide 26 that is attached through the center of the gantry 3.
The upper suspension bracket 17 which slides the bracket guide 18 is attached to the upper end, and the rod stopper 27 is attached to the middle part. One end of the torsion spring 21 is fixed to the lower reinforcing member of the holding frame 1 and the other end is hooked on the link arm 20. When the link arm 20 is constantly rotated clockwise, a reverse reaction force is applied. Structure.

Next, the operation of the present invention will be described. FIG. 4 (a)
(D) shows the position state until the loading of the rolls A, B, and C is completed. When the loading of the roll A starts, and as the roll A descends, the upper spacer 14 is attached to the end face of the cushion material 2 by the lowering force of the roll. At the same time, the upper lever 13 is rotated in a clockwise direction with the upper lever shaft 12 as a fulcrum.

[0016] In this case, the upper stage suspension bar 15 performs a small upward movement of sliding the horizontal axial plane of the upper suspension bracket 17. When the roll A passes down the contact surface of the upper spacer 14, the upper spacer is restored to the initial state (FIG. 4A). This restoring force is generated by the action of the moment arm with the composite center of gravity of the upper lever 13, upper spacer 14, and upper suspension bar 15 always present on the roll side with respect to the upper lever shaft 12, which is the rotation fulcrum of the upper lever 13. It is.

As the roll A descends, the roll A starts to contact the lower spacer 7, and the lower spacer 7 is moved along the arc on the lower surface of the roll A by the same acting force as described above.
Is pushed out, and the same motion as the upper lever 13 is performed with the rotation shaft 4 as a fulcrum, and the lower spacer 7 is brought into a vertical state (FIG. 4B) until the end face of the cushion material 2 is matched.
That is, when the lower suspension bar 8 passes the roll horizontal diameter point, the lower suspension bar 8 moves away from the horizontal axis of the lower suspension bracket 10 and falls down on the upper surface of the roll A in a counterclockwise direction.
Then, the roll A is landed on the cushion material 2 ', and the lower spacer 7 is inserted (FIG. 4C).

The rotary shaft 4 and the dummy arm 19 also perform forward and reverse movements simultaneously with the forward and reverse movements of the lower lever 6. First, from the projecting piece 29 of the dummy arm 19, the link arm 20
The force acting is transmitted in a clockwise direction, the link arm upper suspension bracket 17 with the lift rod 25 is rotated from the intermediate point P point uppermost point Q point also pushed up from H ₂ to H _1, and, the upper with this movement Since the suspension bar 15 is also pushed up, the upper lever 13 also rotates clockwise around the upper lever shaft 12 to bring the upper spacer 14 into a vertical state (FIG. 4B).

Thereafter, the link arm 20 rotates counterclockwise due to the reaction force of the torsion spring 21 and the weight of the parts related to the lifting rod 25, stops at the lifting rod stopper 27, and the position of the link arm 20 is at the uppermost point Q point. To the lowest point O to lower the lifting rod 25 (FIG. 4 (c)).

Since the position of the horizontal axis of the upper bracket 17 is moved to the lowest point H ₃ by the lowering of the lifting rod 25, the upper suspension bar 1 is moved by the moment arm reaction force.
5 is in a state as shown in FIG. Here, the dummy arm 19 is a link arm 20
The rod stopper 27 functions to hold the lowermost point of the upper suspension bar 15 independently of the rotational motion of the upper suspension bar 15 and to follow the rotation angle caused by the fluctuation of the roll diameter. Further, the stopper 28 prevents excessive rotation of the link arm 20 due to the recoil, and always applies a counterclockwise acting force to the torsion spring 21 so as to smoothly move the lifting rod 25 down.

Next, when loading the roll B, the upper spacer 14 can be mounted in the same manner as the operation of the lower lever 6. The roll C only carries out the loading operation into the holding frame 1, and in this state, the loading operation as the three-layer roll storage table is completed. The unloading of the roll can be performed by performing a movement opposite to the loading operation.

In the embodiment, an application example of a roll storage table of a rolling mill has been described. However, the present invention can be applied to any cylindrical object regardless of its diameter. Furthermore, in the embodiment, the lever, the spacer, and the like are two sets each in the upper and lower stages, but the number is not limited to this.

FIG. 5 shows a state where the storage tables are connected in series and the columns of the holding frame are shared. The spacer mounting / dismounting mechanism 30 is provided on a pair of pillars in the roll body length direction, and the storage table A is configured with the other pair of pillars. Then spacer mounting mechanism 3
Storage tables B and C are configured by sequentially arranging the storage tables B and C.

[0024]

According to the present invention, the provision of the dummy arm independent of the link arm avoids the limitation of the rotation of the lower lever due to the size of the roll diameter, and the lifting rod moves down smoothly by the reaction force of the torsion spring. Therefore, the movement of the horizontal axis of the upper suspension bracket has no impact, there is no detachment of the upper suspension bar, etc., and it has high reliability. It is possible.

Further, since the present apparatus has all the mechanisms on one pillar of the holding frame, the storage tables are connected in series, that is,
If the pillars of the holding frame are shared and a device is provided for each pillar, the installation space can be effectively used, and a large number of rolls can be stored. Further, the roll-in / out work can be carried out without a cueing signaler, and two rolls can be carried in / out at the same time, which is a device that can play a great role in rationalizing the transportation and storage work.
