Abstract

PROBLEM TO BE SOLVED: To dispense with the adjustment of an angle of a guide roller and a height of a swing arm even in a continuous operation without distorting a hoop by mounting a table lifter for adjusting a height of hoop at a lower part of a turn table. SOLUTION: A wound and tiered hoop 1 is placed on a turn table 2, and a table lifter 4 is mounted at a lower part of the turn table 2. The hoop 1 is fed out from a guide roller 3. In this device, a height of the hoop 1 can be adjusted by the table lifter 4 so that the height of the hoop 1 can be agreed with that of a guide roller 3, and further with that of a hoop travelling position of a plating device or a press device. The guide roller 3 is set on a linear slide 5, and freely movable in one horizontal direction. Whereby the generation of distortion such as torsion and the like on the hoop 1 can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for continuously feeding hoop material. More specifically, the present invention relates to a continuous feeding device for a long horizontal hoop material wound in a coil shape.

[0002]

2. Description of the Related Art FIG. 3 is a top view of a conventional continuous feeder for hoop material. FIG. 4 is a view as seen from the point A in FIG. Reference numeral 11 denotes a hoop material, 12 denotes a turntable, 13 denotes a tip guide roll, 14 denotes a swing arm, and 15 denotes a potentiometer.

A hoop material 11 wound in a coil shape is stacked on a turntable 12 and placed horizontally. And
It is rewound by the rotation of the turntable 12 and is continuously sent out to a plating device, a press device or the like while being guided by the tip guide roll 13.

In this continuous feeding device, the hoop material 11
The rotation speed of the turntable 12 must be controlled so that the feeding speed of the hoop material 11 does not decrease as the winding diameter of the turntable 12 decreases. This control is realized by the swing arm 14 and the potentiometer 15. In other words, the hoop material 1
When the winding diameter of the hoop material 11 becomes small, the hoop material 11 is greatly pulled by a plating device, a press device, or the like, and as a result, the swing arm 14 swings greatly. The swing angle of the swing arm 14 is measured by a potentiometer 15, and the measurement result is fed back to the turntable 12 to control the rotation speed.

A normal electric motor (induction type, cage type, DC type, etc.) is used to rotate the turntable 12, and the rotation of the turntable 12 is controlled by changing the rotation speed of the built-in motor. It is.

[0006]

The conventional continuous feeding device for hoop materials has the following problems.

Since the swing arm 14 swings, the tip guide roll 13 moves in an arc. Further, the height of the hoop material 11 on the turntable 12 does not match the traveling height of the hoop material such as a plating device or a press device. Therefore, the tip guide roll 13 has an angle, and the hoop material 11 is sent out while being pulled up obliquely.

For this reason, the hoop material 11 serving as a lead frame has a risk that a twist (twist), which is fatal in terms of quality, may occur. When the hoop material 11 is twisted, the plating apparatus has a problem of a decrease in plating position accuracy, and the press device has a problem of poor feeding and a decrease in the press position accuracy.

Further, since the hoop material 11 is usually stacked on a pallet, it is necessary to perform continuous work.
The height and angle of the tip guide roll 13 had to be adjusted according to the height of the hoop material, and much work and time were required for the work.

Accordingly, an object of the present invention is to solve the above-mentioned drawbacks of the prior art, to prevent distortion such as twisting in the hoop material, and to adjust the angle of the guide roll and the height of the swing arm even in continuous operation. It is an object of the present invention to provide a continuous feeding device for a hoop material, which is unnecessary.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a turntable on which a wound hoop material is placed, and sends out the hoop material and controls the number of revolutions of the turntable. And a table lifter installed below the turntable to adjust the height of the hoop material.

Further, the hoop material is so arranged that its height is the same as the height of the guide roll for sending out the hoop material.
In addition, the height of the hoop material traveling position in a processing device such as a plating device or a press device is configured to be the same.

[0013] Further, the hoop material is configured so that the delivery speed is constant.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a top view showing an embodiment of the continuous hoop material feeding device of the present invention. FIG.
FIG. 2 is a front view of FIG. 1. 1 is a hoop material, 2 is a turntable, 3 is a guide roll, 4 is a table lifter, 5 is a linear slide, and 6 is a gear.

The hoop material 1 wound and stacked is placed on a turntable 2, and a table lifter 4 is provided below the turntable 2. The hoop material 1 is sent out from the guide roll 3.

In this apparatus, the height of the hoop material 1 is adjusted by the table lifter 4 so that the height of the hoop material 1 is the same as the height of the guide roll 3 and coincides with the height of the hoop material traveling position of the plating apparatus or the press apparatus. The height of the hoop material 1 can be adjusted. This adjustment can be performed by the operator at any time and easily.

The guide roll 3 is installed on the linear slide 5 and can move freely in one horizontal direction. The movement of the linear slide 5 is transmitted to a gear 6 provided near the linear slide 5, and the movement of the gear 6 is transmitted to a potentiometer, not shown. The transmitted movement is changed into a change in the resistance value of the potentiometer, and the rotation speed of the motor built in the turntable 2 is controlled by the amount of change in the resistance value.

That is, when the winding diameter of the hoop material 1 decreases, the hoop material 1 is pulled by a plating device or a press device, and the guide roll 3 moves linearly with the linear slide 5 toward the plating device or the press device.
This movement amount is transmitted to the potentiometer via the gear 6, and the rotation speed of the motor built in the turntable 2 is controlled. As a result, the delivery speed of the hoop material 1 can be kept constant at all times. The gear 6
Can use a normal rack and pinion, but may use another moving amount transmission mechanism.

In the continuous operation, the height of the table lifter 4 is adjusted to adjust the height of the next hoop material to the guide roll 3.
And the running position of the hoop material of the plating apparatus or the pressing apparatus. This operation can be easily performed as described above. Since there is no need to adjust the angle of the guide roll and the height of the swing arm, which have a lot of know-how as in the related art, the operation can be simplified and the time can be reduced.

As described above, since the hoop material, the guide roll, and the hoop material travel position of the plating apparatus or the pressing apparatus are at the same height, distortion such as twisting does not occur in the hoop material.

The apparatus for continuously feeding hoop material of the present invention can be applied not only to a plating apparatus and a press apparatus, but also to any apparatus that processes or treats hoop material as a material, such as a washing machine.

[0022]

According to the present invention, there is provided a continuous feeder for hoop material, comprising: a turntable on which a wound hoop material is placed;
A guide roll that sends out the hoop material, and is movable in a horizontal direction for controlling the rotation speed of the turntable, and a table lifter installed at a lower portion of the turntable for adjusting the height of the hoop material. The following effects are exhibited by having it.

(1) Since the hoop material, the guide roll, and the hoop material travel position of the plating device or the press device are at the same height, distortion such as twisting does not occur in the hoop material.

(2) The feeding speed of the hoop material is always constant.

(3) Since the height of the hoop material can be adjusted by the table lifter, there is no need to adjust the angle and height of the guide roll during continuous operation, and the operation can be simplified and time can be reduced.
