Description

[Detailed description of the invention] The invention is a continuous delivery device for processed materials.
This invention relates to a continuous feeding device for processing material, which continuously feeds a long material wound into a substantially donut shape to a press machine or the like while being wound by the rotation of a turntable.

Conventionally, this type of processing material delivery device has a structure in which a motor and a turntable are intermittently rotated through a limit switch or the like, and the intermittent rotation of the turntable causes the processing material on the turntable to be unwound and sent to a press machine, etc. are provided. However, in such conventional processing material delivery devices, each time the turntable by the motor rotates intermittently, more processing material than is required for the press machine etc. is wound up, and the wound processing material There was a drawback that the turntable became slack, and when there was less workpiece remaining on the turntable, it moved.

In this invention, the turntable is constantly rotated by a motor controlled by a control device, and when the amount of winding of the processed material is large, the turntable is slow, and as the amount of winding decreases, the turntable is rotated. By configuring the machine to rotate quickly, the above-mentioned conventional drawbacks are overcome, and the processed material can be continuously fed out at a constant speed according to the required amount of the press machine, etc. The present invention provides a continuous delivery device.

Embodiments of the present invention will now be described with reference to the accompanying drawings.

FIG. 1 shows a perspective view, and FIG. 2 shows an operational view. As shown in FIG. It will be sent to third prize. The processed material 1 is illustrated as being in the form of a long strip, which is wound approximately into a donut shape. Although not shown, it may be, for example, a linear material with a circular cross section and wound around a core. Further, the turntable 2 is configured such that the rotating wheel 5 of the motor 4 and two rollers (not shown) are arranged around the center of the lower surface of the turntable 2, and is supported and rotated at three points. This is preferable because the turntable 2 and the rotating wheel come into contact with each other reliably, and the turntable 2 is accurately rotated by the motor 4 and the rotating wheel 5. The material 1 to be processed is suspended on a swinging guide arm 6 and guided to a press machine 3. This guide arm 6
is bendable, and an example is shown in which a folding bracket 7 is attached. Further, the guide arm 6 is attached to the tip of a shaft 10 that is supported on a support rod table 9 fixed to the upper end of the column 8, and is designed to swing about the shaft 10 as a fulcrum. The shaft 10 is rotated by swinging the arm 6. The control device 11 is equipped with a speed setting volume 12, and the above-mentioned shaft 10
The rotation state of the shaft 10 is transmitted to the control device 11. The control device 11 also includes a push button switch for starting and stopping the motor 4. This control device 11 is installed below the support column 8, and a chain 15 is suspended between a sprocket 13 fixed to the rotating shaft of the speed setting volume 12 and a sprocket 14 fixed to the base end of the shaft 10. , an example in which the rotational state of the shaft 10 is transmitted to the speed setting volume 12 is illustrated. Such a control device 1
1 and the motor 4 are connected to each other, the motor 4 is controlled through a control device 11, and the turntable 2 is rotated by the motor 4.

The present invention is not limited to what has been described above. For example, in order to transmit the rotation state of the shaft 10 due to the swinging of the guide arm 6 to the speed setting volume 12, the chain 15
However, other means may be selected. In short, as the guide arm 6 swings in the direction shown in FIG.
0 rotates and the speed setting volume 12 becomes high, and conversely, when the guide arm 6 swings in the direction of A in the figure, the shaft 10 and the control device 11 are arranged so that the speed setting volume 12 becomes low accordingly. It is important to continue the process.

According to the present invention, in order to send the wound workpiece 1 to the press machine 3, the workpiece 1 is first placed on the turntable 2, and its unwound outer end is hung on the guide arm 6. . At this time, the guide arm 6 is bent appropriately to obtain an optimal suspended state, and the work material is guided to the press machine 3, which is set in advance to pull the work material at a constant speed. Then, the guide arm 6 swings from the position A to the position B in FIG.
Next, turn on the start switch of motor 4,
The turntable 2 is also rotated by the rotation of the motor 4 and the rotary wheel 5, and the wound workpiece 1 is fed out to the press machine 3 while being unwound. Initially, there was a large amount of processing material 1 remaining, that is, processing material 1
Since the diameter is large, even if the rotation of the turntable 2 is slow, the required amount of the press machine 3 can be met. Since the press machine 3 is set to pull the workpiece 1 at a constant speed, the lower end portion of the guide arm 6 is gradually pulled in the direction C as the diameter of the workpiece 1 becomes smaller. When the lower end portion of the guide arm 7 is swung in the direction C by this action, the shaft 10 to which the base end portion is fixed rotates, and the rotation is transmitted to the speed setting volume 12 through the sprockets 13, 14 and the chain 15. The speed setting volume 10 gradually increases. Accordingly, the rotation of the motor 4 and turntable 2 gradually becomes faster. Further, when adding a new material 1 to be processed, etc., the suspension on the guide arm 6 is released. Then, at the same time as the guide arm 6 returns to the position A due to the weight 7, the shaft 1
0, the sprockets 13, 14 and the chain 15 rotate in the opposite direction to the above, and the speed setting volume 12
will also be returned. Furthermore, when several rolled processed materials 1 are stacked and fed out while being unwound from the inner end, the guide arm 6 gradually swings from the direction C to the direction A, and the speed changes accordingly. The setting volume 12 also gradually decreases, and the rotation of the motor 4 also slows down, which works in the opposite manner to the above.

As described above, according to the present invention, when there is a large amount of remaining winding of the modified material placed on the turntable, the rotation of the turntable is slow, and as the remaining amount of winding decreases, the turntable rotates slowly. The machine gradually rotates faster, so there is no problem of the workpiece loosening or moving like in the past, and the workpiece is always moved at a constant speed according to the amount required by the press machine, etc.
Moreover, it can be sent out continuously.
