 Next, the present invention will be specifically described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which a continuous automatic pack gripper continuously and automatically grips an extrusion-coated cable following an extruder line. It is a schematic diagram of a structure.

In FIG. 1, the cable 1 sent out from the extrusion line basically includes a pack take-off machine 3 and a turntable 4.
Is picked up by a continuous automatic grabber.

The cable 1 pulled out of the pack take-off machine 3 is put into a rotary guide tube 12, falls naturally into the pack 5 and is grasped.

At this time, the rotary guide tube 12 guides the cable 1 to the pack 5 and assists in grasping the cable 1 stored in the pack 5 neatly.

The turntable 4 has a plurality of (several to several tens) packs 5 prepared in advance and a plurality of openings for mounting the packs 5 having a diameter corresponding to the pack diameter. The cable 1 is continuously dropped on the pack 5 and accumulated.

When one pack 5 is full, a drive motor 13 for rotating the turntable 4 to switch to the spare pack 6, and a speed reducer 14 for decelerating and changing the rotation speed of the turntable 4 and The transmission 15 is provided.

Moreover, the wire holding guide 7 is provided above the turntable 4.

As shown in FIG. 3, when the cable 1 is fully wound, the wire holding guide 7 is moved by the air cylinder 19 when the full-pack 8 and the spare pack 6 are replaced.
Up and down to assist with pack replacement.

That is, the wire holding guide 7 located above the preliminary pack 6
After moving the cable 1 into the spare pack 6, the presser guide 7 is raised, and the rotary guide tube 12 guides the cable 1 into the pack (the previous spare pack 6), and the rotary guide tube 12 rotates. While storing the cable 1.

Also, the distal end portion 12 'of the rotary guide tube 12 is surrounded to prevent the cable 1 that falls freely into the pack 5 from being disturbed and protruding.

Further, as shown in FIG.
At an appropriate position around the pack, a pack extension detector 16 for detecting the presence or absence of the cable 1 stored in the pack 5, a spare pack detector 17 for detecting the presence or absence of the spare pack 6, and Each of the limit switches 18 for determining the position of the spare pack 6 is provided.

The continuous automatic grasping machine of the present invention can continuously automate cables by adopting these configurations.

(Action) Prevention of cable from protruding from spare pack 6; action of speed reducer linked with turntable.

In the continuous automatic grasping machine of the present invention, if the single length of the cable grasped in the pack 5 is, for example, 1,000 m, the length is preset in the counter 11, and when the set count is reached, the turntable 4 rotates. , The operation to switch to the spare pack 6 is performed.

In this case, if the switching is performed with the line speed of the cable production, the cable 1 may protrude from the pack 5, so that the counter 11 is also preset with 1,000 m and another, for example, 950 m. Thus, when the preset of 950 m is reached, the pack take-off machine 3 is moved to the production linear speed.
Decelerate by about 80%.

Next, when the read value of the counter 11 reaches 1,000 m, the turntable 4 is rotated by one pitch by the drive system of the drive motor 13, the speed reducer 14 and the transmission 15.

When the position of the next spare pack 6 is determined by the limit switch 18, the drive motor 13 stops. Then, as shown in FIG. 3, the wire press guide 7 of the up-and-down drive type is lowered to prevent the cable 1 in the pack 5 from being randomly wound and protruding outside (FIG. 3-2).

Subsequently, the up-and-down driving type wire presser guide 7 is raised to a fixed position by a timer (not shown) (3-3-3).
Similarly, the pack take-up machine 3 is accelerated to the production linear speed by the timer, and returns to the normal state (FIG. 3-1).

Thereafter, the operation is repeated for the length preset in the counter 11. The cable 1 decelerated during this switching is absorbed by the accumulator 10, and a constant linear speed of the production line is maintained.

As described above, by configuring the continuous automatic control device and the continuous automatic control mechanism, the ignition cable for the vehicle and the continuous automatic pack can be picked up.
