The side guide roll moving mechanism 24 is provided for each of the left and right side guide rolls 5, and includes a ball screw 25 extending in the width direction of the drum 2, a motor 27 for rotating the ball screw 25 via a coupling 26, and A small block 28 that moves horizontally by the rotation of the ball screw 25, and L that guides the horizontal movement of the small block 28 and prevents co-rotation.
An M guide 29 is provided.

The side guide roll 5 is fixed below the small block 28 via an arm 31.

The block 7 is provided with a drum size detecting mechanism 32 for detecting the width and height of the drum 2 to be set. The drum size detection mechanism 32 includes a photoelectric switch 33 for detecting the width of the drum 2 and a photoelectric switch 34 for detecting the height.

The photoelectric switch 33 is a reflection type photoelectric switch, and is provided vertically downward to the arm 31 and directed downward. The photoelectric switch 33 is connected to each side guide roll 5.
And at a position substantially equivalent to the inner end thereof. When the side guide roll 5 gradually moves horizontally and the end of the drum 2 is positioned directly below the photoelectric switch 33, the width is detected from the end. This detection signal is transmitted to a control device (not shown) to stop the motor 27 and
The horizontal movement of each is stopped.

The photoelectric switch 34 is a transmission type photoelectric switch, and is provided at the lower end of the block 7 so as to sandwich the drum 2. The block 7 is gradually lowered, and the drum 2 is positioned between the photoelectric switches 34. Then, the height from the top of the drum 2 is detected. This detection signal is transmitted to a control device (not shown), and after a predetermined distance from that point, the motor 15 is stopped to stop the lowering of the block 7.

The under roll 3 is provided in a hole 35 formed at a lower portion of the frame 6.

As shown in FIG. 2, the under roll 3
Two rows are provided in parallel with the guide roll 4. One (right side in the figure) underroll 3 has a fixed height and horizontal position, and the other (left side in the figure) underroll 3
Are provided so as to be vertically and horizontally movable.

An under-roll horizontal moving mechanism 37 for horizontally moving the under-roll 3 is provided on the base 36. The under-roll horizontal moving mechanism 37 includes:

A hydraulic table lifter 46 is provided below the base 36 so as to move the under roll 3 up and down together with the under roll horizontal moving mechanism 37.

Drum 2 placed on under roll 3
Is rotated by the rotation of the underroll 3. Hereinafter, the rotation driving mechanism 47 of the underroll 3 will be described.

As shown in FIG. 3, a motor 51 is connected via a belt 49 to a rotating shaft 48 of the underroll 3 on the fixed side (lower side in the figure). The under roll 3 rotates.

The rotating shaft 48 extends in the axial direction, and is connected to a shaft 53 via a coupling 52. A shaft 54 connected to the underroll 3 on the moving side (upper side in the figure) is provided in parallel with the shaft 53. These shafts 53 and 54 are connected by a belt 55 so as to transmit rotational force by the same rotation.

A universal joint 56 is provided between the shaft 54 and the under-roll 3 on the moving side so as to transmit a rotational force while following up and down and horizontal movement of the under-roll 3. .

Next, the operation will be described in accordance with the procedure for sending and winding a striated body such as a cable by the under-roll sending / winding device 1 having the above-described structure.

First, the underroll 3 on the moving side is horizontally moved in accordance with the size of the drum 2 to be set. That is, when the large drum 2 is used, the interval between the underrolls 3 is widened, and when the small drum 2 is used, the interval between the underrolls 3 is narrowed, so that the rotational stability of the drum 2 is improved. Can be done.
This also allows the use of drums 2 of a wide range of sizes.

Next, the guide roll 4 is lowered together with the block by the block moving mechanism 8. Then, the guide roll 4 is stopped at a suitable height according to the detection signal of the photoelectric switch 34. At this time, after the photoelectric switch 34 detects the top of the drum 2, the motor 15 is stopped and the block 7 is stopped after a predetermined distance from the point of time. 2 can be biased downward.

Further, the side guide roll 5 is horizontally moved inward by the side guide roll moving mechanism 24. Then, each side guide roll 5 is stopped at a suitable position by a detection signal of the photoelectric switch 33. As a result, it is possible to prevent the sideslip when the drum 2 rotates.

Guide roll 4 and side guide roll 5
By automatically performing the movement and the position determination, there is no need for the labor and time for changing the mounting dimensions as in the related art, and the loss can be reduced.

Then, the motor 51 is driven to rotate the under roll 3, so that a wire or the like is fed and wound.

At this time, as described above, the guide roll 4
By biasing the drum 2 downward,
The drum 2 is appropriately urged by the underroll 3 to prevent slippage and prevent the drum 2 from separating from the underroll 3. Further, the slight vibration of the drum 2 can be absorbed by the spring 23.

Further, by connecting the shaft 54 and the moving underroll 3 with the universal joint 56, the rotational force can be transmitted to the underroll 3 and the vertical and horizontal movement can be performed.

When the feeding and winding of the filament have been completed, the drum 2 is removed. At this time, the hydraulic table lifter 46 lifts the underroll 3 on the moving side upward, so that the underroll 3 can be easily kicked out.

In the above embodiment, one under roll 3 is fixed, but both under rolls 3 may be movable horizontally and vertically. This is preferable because the axis of the rotating drum 2 can be kept constant.

[0047]

In summary, according to the present invention, the excellent effects of preventing the drum from slipping and separating on the under roll and automatically adapting to drums of various sizes are exhibited.
