Also, reference numerals 313 and 316 limit the sections in which the holder and the power transmission member are moved by the limit switch.

Hereinafter, the operation state of the branch pipe feeder having the configuration as described above and its operation will be described in detail.

First, when the paper roll R is transferred to the working position, the operator operates the drive motor 352 of the holder moving part 350 so that the paper roll R is provided within the gap between the holders 330. ) To move and narrow the gap between the holders 330 to hold the paper roll (R). This can be satisfied by allowing the holder movement bar 355, which is transmitted with the power of the driving motor 352, to be rotated so that the holder 330 is moved within the screw portion 355a of the holder movement rod 355.

At this time, the holder movable rod 355 may be formed with a threaded portion 355a having different winding directions from each other, such as a threaded portion formed in a conventional one-piece type, but in particular, the direction in which the holder movable rod 355 is wound more than a fabrication piece is the same. Since it is preferable to form a general right-hand thread 355a defined in the present embodiment, the operation state and action by the thread 355a having the same mutual winding direction will be described.

Accordingly, when the driving motor 352 is rotated counterclockwise as shown by the arrow direction of FIG. 4, the holder moving rod 355 connected to the driving motor 352 with the driving and driven gears 353 and 354 is rotated clockwise. Thus, the holder 330 is moved toward the center of the device due to the nature of the right hand screw. Here, the action that the holder 330 flows is when the screw pipe 331 is screwed together to the threaded portion 355a of the holder movable rod 355 to rotate the holder rod 355, the spiral of the threaded portion 355a The ride screw tube 331 is satisfied by moving.

That is, the state in which the holder 330 is moved by combining the directions in which the two driving motors 352 are rotated is described. If the rotation directions of the two driving motors 352 are different from each other, the holder 330 is described by the above description. When the holder 330 is moved to the position where the paper roll (R) is moved in the same direction to maintain a constant interval and the rotational direction of both drive motors 352 are the same direction, the holder as described above 330 is the gap between each other is narrowed or widened to hold or release the paper roll (R).

After the paper roll R is caught by the holder 330 as described above, the operator operates the drive motor 352 so that the paper roll R floats at a predetermined distance from the floor of the work place, and the paper of the paper roll R Loosen P) and hang it on the transfer roller 313 to complete the paper feeding operation in the paper cutting of paper.

At this time, the operation of lifting the paper roll (R) in more detail, when the drive motor 372 is rotated, as shown in Figures 5 and 6, the rotational power generated in the drive motor 372 is driven The rotation shaft 382 is rotated by the belt 375 which is a transmission means, and the rotation shaft 382 is rotated, and the worm 383 coupled thereto is rotated at the same time as the rotation shaft 382 is rotated. , The worm 383 and the worm wheel 384 geared together are also rotated at the same time so that the screw rod 385 screwed into the screw hole 384a of the worm wheel 384 is a straight line in the direction in which the paper roll R is held. Are exercised.

When the screw rod 385 flows as described above, the power transmission member 390 coupled thereto is moved, and the power transmission member 390 pushes the shaft pivot member 391 coupled with the holder support shaft 320. Thus, the shaft pivot member 391 is rotated at a predetermined angle, and the holder 330 coupled to the holder support shaft 391 is pivoted at a predetermined angle so that the paper roll R is lifted.

Here, since the power transmission member 390 and the shaft rotation member 391 is hinged by the coupling pin 392, the shaft rotation member 391 is rotated by a predetermined angle to move the engaging portion with the power transmission member 390. Even if the load is not applied, the load generated when the engaging portion flows upward by the rotation of the shaft pivot member 391 is combined with the hinge plate 314 on which the component support 371 is coupled on the mounting table 310. It is resolved by the rotation. In other words, when the component support 371 is rotated in response to the amount of rotation of the shaft rotating member 391, the operation of lifting the paper roll R is performed smoothly.

In addition, when the paper roll (R) is lifted, the paper roll (R) generates a downward load so that the pivoted holder (330) is to be rotated downward, but this is because the threaded rod (385) Combination with the worm wheel 384 of the gear housing 381 is overcome by the brace action.

In addition, the braking device 335 installed in the holder 330 is rotated at the same time as the base support 332 when the base roll (R) is caught by the base support roll 332 to stop the operation, the rotary plate ( 334) to intervene and stop.

As described above, the present invention is because the holder is moved by the power provided in each of the holders by moving only the holders on both sides, so that even if the paper roll is not located in the correct position, it is easier to hold the mounting table used in the past or No cylinders are required, resulting in a smaller footprint on the machine floor.

In addition, since each driving part operated by the cylinder device is operated by the power of the motor, the manufacturing cost is reduced, repair is easy even in case of failure, and the repair cost is lower.

In addition, since the holder holding the heavy paper roll is configured to support the mechanical force, that is, the force of the metal rod body, the paper feeding operation is more stably performed, thereby reducing the breakage rate of parts.

Therefore, the present invention is a useful invention that can satisfy both the manufacturer of the device or the operator using the device.
