BACKGROUND OF THE INVENTION This invention is applicable to continuous feeding of long plate materials, for example, when exchanging the feed from a plurality of uncoiler bodies each of which is wound and held in a roll shape in advance. The present invention relates to an apparatus for feeding a long material that prevents unwinding and loosening when unwinding a plate material sent from an uncoiler body.

[0002]

2. Description of the Related Art Various products, for example, plate cutting pieces of duct members, are cut and punched from a long plate material having a predetermined width.
In forming and the like, the raw material wound in a roll shape is sequentially pulled out and transported to various predetermined processing machines on a transport line. For this transporting and feeding, for example, the thickness of the plate material corresponding to the product to be processed,
A plurality of uncoiler bodies are arranged side by side so as to be able to cope with, for example, replacement of consumed raw material when the composition material and the like are different.

That is, as shown in FIG. 3, a plurality of uncoiler bodies R each formed by winding a conveyed member W, which is a raw material having a predetermined width, in a roll shape, are placed on a conveyer base 1 along the feeding direction. An uncoiler section is formed by sequentially arranging the uncoiler parts, and each of the uncoiler bodies R is separately sent out while exchanging the member W to be conveyed, and various kinds of processing are performed by various processing machines such as a plasma cutting machine 21 arranged on the conveyance line. Is performed.

At this time, in order to exchange the transported members W sent out from the respective uncoiler bodies R, the transported members W which have been sent out to the various processing machines (21) need to be unwound while being rewound. The sending edge is pulled out from the uncoiler body R and is sequentially sent out. When the uncoiler body R is consumed, the uncoiler body R is replaced with a new one, and the sending edge of the uncoiler body R is set again.

[0005]

However, prior to sending out a new transported member W, it is necessary to rewind the transported member W that has been transported before the delivery of the new transported member W when replacing the transported material from the uncoiler body R. At the time of rewinding, the rewinding speed is different from the unwinding speed, and the moving speeds of the left and right side edges of the transported member W are slightly different due to various obstacles, irregularities, etc. on the transport line. It is virtually impossible to rewind. As a result, the transported member W of the uncoiled body R that has been rewound may be unwound, loosened, or the like. As a result, when the material is again delivered, the delivery position must be corrected on the transport line, which is extremely troublesome. .

In other words, if the left and right sides of the transported member W do not move evenly due to obstacles, irregularities, etc. on the transport line, and if there is a speed change during rewinding, the uncoiler body R will be unwinding, loosening, etc. It is considered that this winding deviation, loosening, and the like are caused by a deviation between the unwinding direction of the transported member W at the time of rewinding and the winding direction by the uncoiler body R.

In view of the above, the present invention has been devised in view of the above-mentioned various circumstances. For example, a long coil-shaped conveyed member in a plurality of uncoiler bodies juxtaposed is selectively exchanged. A feeding device for a long material, which prevents unnecessarily conveyed members from unwinding, loosening, and the like occurring when rewinding an unnecessary conveyed member, and is capable of exactly rewinding to an original position. It is the purpose.

[0008]

In order to achieve the above-mentioned object, according to the present invention, a long transported member W is selected from an appropriate number of uncoiler bodies R wound in a roll shape. The uncoiler base 3 on which the uncoiler body R is mounted is provided with a free bearing body 5 having a protruding and freely rolling load supporting ball 6 on the upper surface. It is movably supported on the upper surface of the installation base 1.

[0009]

In the feeding device for a long material according to the present invention, the uncoiler body R feeds the conveyed member W by being rotated in the feeding direction, or is rotated in the rewinding direction which is the opposite direction. Thereby, the transported member W is rewound.

The uncoiler base 3 of the uncoiler body R is
By being set on the free bearing body 5 having the load-bearing ball 6 which protrudes and rolls freely on the upper surface, it can be swung freely in all directions. This swinging motion is caused when the transported member W is unwound when the transported member W is rewound.
It automatically avoids the resistance of the transported member W due to the winding deviation, relaxation, and the like occurring therein, and corrects them.

At the time of unwinding, it moves in the left-right direction corresponding to the unwinding, and at the time of relaxation, it moves in the front-back direction to a tightly winding position. Make it correspond automatically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a transport surface 2 on which a number of freely rotating transport rollers, rollers, etc. are appropriately arranged. A suitable number of, for example, five uncoiler bases 3 are provided on the installation base 1 along the feeding and conveying direction of the member W to be conveyed, which is a long coiled plate material. It is provided and arranged (see FIG. 3).
On the uncoiler base 3, driving rollers 4 before and after mounting an uncoiler body R around which a conveyed member W is wound in a roll shape are supported and arranged, and a disc-shaped side wall of the uncoiler body R is provided. The drive motor 9 rotates at least one of the driven rollers 9 so that the uncoiler body R itself is rotated by abutting the peripheral edge of the uncoiler body R.

The uncoiler body R mounted and supported by the front and rear drive rollers 4 has its outer peripheral edge position at the maximum diameter of the conveyed member W sent out thereby set higher than the upper surface of the uncoiler base 3. There is.

The uncoiler base 3 shown in the figure is framed by a rectangular tubular steel material in a cross-section arranged in the left, right, front and rear so as to be substantially rectangular in plan.
Further, it has a reinforcing structure capable of sufficiently supporting the load of the transported member W wound thereon.

The uncoiler base 3 includes an installation base 1
Above, it is a floating type that can freely move in any of the front, rear, left and right directions, and is supported and mounted on the installation base 1 via a plurality of free bearing bodies 5 fixed to the upper surface of the installation base 1. . The free bearing body 5 has a load supporting ball 6 which protrudes and rolls freely on the upper surface, and the uncoiler base 3 is provided on the upper surface of the load supporting ball 6.
As shown in FIG. 2, the uncoiler base 3 is supported in a floating state by six free bearing bodies 5, for example, three on each of the left and right sides, as shown in FIG.

The uncoiler base 3 is provided on at least four corners of each of the step portions of the installation base 1 on which the uncoiler bases 3 are supported so as not to fall off the installation base 1. Is provided with a stopper 7 having a substantially L-shape in a plane with which it contacts.

Furthermore, the left and right side edges of the transported member W at the time of rewinding come into contact with the inner side surfaces of the left and right side walls of the installation base 1, and the rewinding for setting a predetermined rewinding position in the left and right direction. A guide 8 is provided. When both side edges of the transported member W abut against the inner surface of the rewind guide 8, a winding resistance occurs when the uncoiler body R is wound up,
The uncoiler body R moves following the resistance. In addition,
Instead of the rewind guide 8, the right and left side walls of the installation base 1 can be used as they are.

On the other hand, the uncoiler base 3 detects the sending edge of the member W to be conveyed and pulls out the edge.
A pull-out unit 10 for feeding the sheet onto the transport surface 2 is provided.
As shown in FIG. 1, the pull-out means 10
The rotation of the uncoiler body R was temporarily stopped by detecting the sending edge of the transported member W in the uncoiler body R when the uncoiler body R was rotated in the rewinding direction opposite to the feeding direction of the uncoiler body R and stopping the drive motor 9. Thereafter, the first sensor 11 for instructing control to rotate in the reverse direction, and the second sensor 11 for detecting that the feed edge fed from the uncoiler body R rotated in the feed direction is at the feed position.
It comprises a sensor 12 and a movable pressing and holding roller body 13 which is instructed by the detection operation of the second sensor 12 to press and hold the sending edge.

As shown in the figure, the installation base 1 itself has a stepped structure in which the front part in the feeding direction is high and the rear part is low, and each of the step parts has one step.
Each of the uncoiler bases 3 is supported, and the conveying surface 2 of the member W to be conveyed sent out from each of the uncoiler bases 3 is vertically arranged in the installation base 1 to form a main conveying line to various processing machines (21). It is to be merged. For this reason, for example, when the transported member W is exchanged, the rewinding position when rewinding the transported member W can be set to a position where the transported member W joins with the main transport line, thereby reducing unnecessary rewinding work and improving work efficiency. Can be achieved.

Reference numeral 14 in FIG. 2 denotes a rewind detection sensor, which is a member W to be conveyed on the conveyance line.
When rewinding is performed, the end of the rewinding operation is confirmed by detecting the sending end edge, and a control instruction is given to stop the drive motor 9.

Next, as an example of the use of this, as shown in FIG. 3, an uncoiler body R holding a conveyed member W, which is a variety of long plate material, wound in a roll shape, will be described. Is set on the uncoiler base 3 on the installation base 1 so that steps are set along the transport direction and arranged side by side.
Then, a predetermined processing machine in front of the transfer line, for example, a plasma cutting machine 21 or the like sends out the mold so as to perform the cutting. The plasma is passed through a side guide 22, a length measuring device 23, an ink jet printer 24, a shear 25, a conveyor 26, and the like. It is sent to the cutting machine 21.

At the time of sending out, the material is exchanged,
By sending it out from another new uncoiler body R after spending, the transported member W in each uncoiler body R
Is selected, the transported member W that has been sent out is rewound from the processing machine (21) side. And
When the uncoiler body R rotated in the rewind direction winds the transported member W, the left and right sides of the transported member W do not move evenly due to obstacles on the transport line, irregularities, and the like,
If there is a speed change during rewinding, if the side edge of the transported member W does not match the side edge position in the uncoiler body R, and the winding resistance is generated, the uncoiler base 3 itself is appropriately adjusted to avoid the resistance. It relatively moves back, forth, left and right (see FIG. 2).

That is, a winding deviation generated at the time of rewinding,
Relaxation and the like are automatically corrected beforehand by the relative movement of the uncoiler base 3 via the free bearing body 5 on the installation base 1 (see the white arrow in FIG. 2), and the uncoiler body 3 is tightly fixed. It is wound up at the right position of R.

[0024]

The present invention is configured as described above, and therefore, when the conveyed member W which is a long plate material in the plurality of juxtaposed uncoiler bodies R is selectively replaced, the conveyed member becomes unnecessary. When automatically rewinding the transport member W,
It is possible to prevent unwinding, loosening, and the like occurring during unwinding, and to exactly rewind to the original position.

That is, in the present invention, the uncoiler base 3 is movably supported on the upper surface of the installation base 1 by interposing a free bearing body 5 having a load-supporting ball 6 which protrudes and rolls freely on the upper surface. In addition, since the uncoiler base 3 automatically moves so as to avoid winding resistance at the time of rewinding, there is no need to incorporate special control means, and the mechanism is extremely simple.
Maintenance is also easy.
