Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a method in which a wide metal strip is cut into a large number of narrow metal strips, and a flat object such as a multiplicity of coiled metal strips is lifted and racked. The present invention relates to a flat object lifting device used for storing and packing in a storage container, and a device for storing a metal strip coil in a rack using this device.

[0002] In order to cut a wide metal strip into a number of narrow metal strips, a metal stripping apparatus 1 as shown in FIG.
00 is used. This metal cutting device 100
Is a wide metal strip 1 fed from the uncoiler 102
Is supplied to the cutter 112 via the guide rollers 104, 106, 108 and the guide roller group 110, and a large number of narrow metal strips 2 formed by the cutter 112 are cut through the pinch roll 114. And winds it up on a winder 116.

When the cutting cutter 112 cuts the wide metal strip 1 into a large number of narrow metal strips 2, the adjacent narrow metal strips 2A and 2B are mutually connected as shown in FIG. Feeding at narrow intervals, these adjacent metal strips 2
13A, and one of the metal strips 2A is guided to the left side in FIG. 13 and is passed through the distribution guide roll group 118A to the winding shaft 116 of the left winding section 116A of the winding machine 116.
a, and the other metal strip 2B is guided to the right side in FIG. 13 and is passed through the distribution guide roll group 118B to the winding shaft 1 of the right winding section 116B of the winding machine 116.
16b. Therefore, the winding portions 116A, 11
6B has a coil receiving surface in the same direction, and the coil holder 132 described later includes the winding portions 116A, 116A.
The metal strip coils 3A, 3B are received from the coil receiving surface of B in the same direction. The adjacent metal strip coils 3A and 3A or 3B and 3B of the metal strip coils 3A and 3B formed by sorting and winding the metal strips 2A and 2B.
The space between B and B is maintained by the spacers 4A or 4B fitted to the winding shafts 116a and 116b in advance (see FIGS. 15 and 16).

The reason why a large number of narrow metal strips 2A and 2B formed by cutting are distributed to the left and right is as follows.
If it is guided to the winding machine 116 without sorting, the interval between the adjacent narrow metal strips 2 is extremely small, so that the metal formed by being wound by the winding machine 116 while maintaining the same interval is maintained. This is because the interval between the strip coils 3 is extremely small, and it is difficult to take out these metal strip coils 3 and store them in a rack. If a large number of narrow metal strips 2 are to be dispersed in the width direction while being spaced from each other and are to be wound on the winder 116, the width of the winder becomes extremely large, and the equipment becomes large. In addition, the metal strip 2 must be bent while being bent in the direction parallel to the plate surface, but it is difficult to bend the metal strip 2 in the direction parallel to the plate surface, which is not practical.

[0005] Each of the winding portions 116A of the winding machine 116 is cut by the metal cutting device 100 shown in FIG.
116A, a metal strip coil 3A formed freshly wound on
3B is taken out from the winding shafts 116a and 116b, lifted and conveyed, stored in a rack (part of which is indicated by reference numeral 142 in FIG. 17), packed, stored, or shipped. . Therefore, the winding shaft 1
16a and 116b are in a cantilever form whose ends are open to facilitate removal of the metal strip coil 3A or 3B from the ends. The metal strip coils 3A and 3B may be directly taken out from the winding shafts 116a and 116b of the winding sections 116A and 116B of the metal strip splitting device 100 and lifted. However, as shown in FIG. The coil coils 3A, 3B are received by a coil holder 132 having coil receiving arms 130A, 130B, and the coil holder 132 is transported to a predetermined lifting position.
A and 3B may be lifted. This coil holder 13
The structure and operation of No. 2 will be described later in detail in connection with the lifting device of the present invention.

[0006] In this case, the metal strip coils 3A and 3B are taken out of the rack and subjected to subsequent processing. The winding direction is the same so that the winding end ends of the metal strip coils are drawn out from the same direction. It is required to be stored. Therefore, each of the metal strip coils 3A and 3B is lifted and conveyed to the rack with its flat surfaces (surfaces formed by spirally winding both edges of the metal strip) maintained in a vertical state. It is desired. In addition, winding shaft 1
The winding direction of the metal strip coil 3A wound and formed on each of 16a and 116b is clockwise in FIG. 13, while the winding direction of the metal strip coil 3B is counterclockwise. Since the winding directions of the metal strip coils 3A and 3B are opposite, one of the metal strip coils, for example, the metal strip coil 3B is turned 180 ° so that it is in the same direction as the metal strip coil 3A, and the metal Storing is required.

In one prior art, FIGS. 15A and 15B
As shown in FIG. 5, a metal strip coil 3A or 3B is formed by using a hanging string 124 such as a nylon sling which is hooked on a hook-shaped hanging bracket 122 which is hung on a crane or the like (not shown).
Is lifted and transported to the rack. In this prior art, as shown in FIG. 15A, after guiding the metal strip coil 3A or 3B to the cutout portion 116a 'or 116b' at the take-out end of the winding shaft 116a or 116b, the hanging string 124 is connected to the notch 116a 'or 116b'. The metal strip coil 3A or 3B is lifted through the coil hole of the metal strip coil 3A or 3B at the notch 116a 'or 116b'.

In another prior art, as shown in FIGS. 16A and 16B, a hook portion 126a of the lifting member 126 is formed by using a C-hook-shaped lifting member 126 suspended by a hanging metal fitting 122. The metal strip coil 3A or 3B is hung on the coil hole of the strip coil 3A or 3B and lifted and transported to the rack. In this prior art, as shown in FIG. 16 (A), after holding the hook portion 126a of the lifting member 126 on the winding shaft 116a or 116b so that the upper surfaces thereof coincide with each other, the winding portions 116A and 116B Provided coil pusher 128A or 128B
Is driven to transfer the most advanced metal strip coil 3A or 3B on the take-out side to the hook 126a of the lifting member 126 to lift the metal strip coil 3A or 3B.

It should be noted that the lifting positions are the winding portions 116A, 1
16B, the suspension string 124 or the lifting member 126 is not the winding shaft 116a, 116b, but the coil of the coil holder 132 that has previously transported the metal strip coils 3A, 3B to the lifting position as described above. At the ends of the receiving arms 130A, 130B, the metal strip coil 3A or 3B is received and lifted.

In still another conventional technique, a pair of holding arms for lifting an outer peripheral surface of a coil from below and a pair of holding arms for removing any one coil from a number of coils closely arranged with each other. There has been proposed a coil lifting device including a lifting arm having a hook (engaging claw) for lifting a coil by hooking the coil in a coil hole lifted by a holding arm (Japanese Patent Laid-Open No. 8-2).
No. 6662).

[0011]

However, the suspension string 124
The method shown in FIG. 15 using the method has a drawback that the efficiency of the lifting operation is extremely low because the worker has to manually pass the suspension string 124 through the coil hole of the metal strip coil 3A or 3B. In addition, if the metal strip coil 3A or 3B has a large diameter, the position through which the hanging string 124 passes is increased, and the worker must work on the platform.
Lifting work was dangerous because it was a work at height.

The method shown in FIG. 16 using the C-hook-shaped lifting member 126 can automate the work, thereby solving the problem of workability. However, the metal strip coil 3A or 3B can be mounted on the rack in the same manner. There is a disadvantage that it cannot be stored in a rack at small intervals because it is loaded and unloaded in an orientation.

Referring to FIG. 17, this will be described in more detail. One of the metal strip coils 3A can be housed in a rack 142 at a small interval sequentially from one side, as shown in FIG. However, since the other metal strip coil 3B must be stored in the rack 142 in the opposite direction to align the winding direction as described above, the metal strip coil 3B stored last in the rack 142 is used. The metal strip coil 3B cannot be stored unless a considerable interval is provided next to 3A. This interval is a value equal to or greater than the sum of the thickness of the lifting member 126 and the stroke required to remove the hook portion 126a from the coil hole. Therefore,
The metal strip coils 3A and 3B cannot be stored in a rack at a high space factor and packed.

Further, in the prior art described in Japanese Patent Application Laid-Open No. Hei 8-26662, the coil is lifted using the lifting arm with the hook, so that the hook is pulled out from the coil hole as in the prior art shown in FIG. Requires a large stroke corresponding to the length of the hook, and has similar disadvantages.

In each of the methods, the hanging string 124
The hook portion 126a is hung up through the hole or the hole, so that an object having a hole large enough to pass a string or hook a hook like a metal strip coil can be lifted, and there is no hole. There is a drawback that a flat object with a small hole cannot be lifted.

One problem that the present invention seeks to solve is:
It is an object of the present invention to provide a flat object lifting device capable of lifting and conveying a flat object such as a thin metal coil with a small stroke.

Another object to be solved by the present invention is to provide a flat object lifting apparatus capable of stacking and unloading flat objects at small intervals in both forward and reverse directions.

Still another object to be solved by the present invention is that a plurality of narrow metal strips formed by cutting a wide metal strip are alternately distributed and provided with a plurality of coil receiving surfaces having the same direction coil receiving surface.
