The invention is a continuous working system, only need to put the reel 2 to be rolled on the upper shaft mechanism 35 manually, carry on blanking, upper shaft, upper reel and go out the reel automatically, the concrete process is:

the film 1 waiting for coiling is tensioned and fed in a double-row mode through the rack 5 and is coiled on a large-diameter roller of a rotating film discharging roller 9, and the film discharging roller 9 rotates clockwise slowly under the action of autonomous power.

The two ends of the scroll 3 are clamped between two bearings at the upper end of the supporting bearing frame 10 and roll together with the bearings, the supporting bearing frame 10 compresses the scroll 3 on the film discharging roller 9 through the supporting bearing frame return spring 11, the scroll 3 is compressed on the film discharging roller 9 to rotate together, and the film on the film discharging roller 9 is wound on the scroll 3. As the film on the spool 3 increases and the thickness increases, the spool 3 and the support bearing frame 10 together move progressively away from the film take-off drum 9 until the support bearing frame 10 is pushed up against the web full stroke switch 39.

The coil full-stroke switches 39 at both ends output signal jump to perform automatic reel change operation.

The method comprises the following three steps:

in the first step, the film is cut and divided when the winding shaft 2 falls.

The reel to be rolled 2 is arranged on an upper shaft bracket 41 of the upper shaft mechanism 35, the upper shaft bracket 41 has a certain downward inclination, and the swinging rack 36 is driven to swing by the swinging rack driving cylinder 37, so that the reel to be rolled 2 is discharged along the downward inclination one by one. After the winding shaft 2 is discharged, the film falls down on the film winding shaft brackets 25 at two sides of the film discharging roller 9, at the moment, the telescopic double-shaft cylinder 26 is in an extending state, and the film winding shaft bracket 25 is supported to receive the winding shaft 2 to be wound.

The mandril of the telescopic double-shaft cylinder 26 contracts, the film winding shaft bracket 25 drives the to-be-wound winding shaft 2 to fall, and the to-be-wound winding shaft 2 is in close contact with the arc surface of the film discharging roller 9 and rotates together under the driving of the film discharging roller 9. The lifting cylinder 19 is retracted from the original extending state to drive the lifting beam 18 to descend, the lifting beam 18 compresses the synchronous pressure rod 33 through the pressure rod spring 28, and the anti-skidding friction plates 27 on the synchronous pressure rod 33 enable the synchronous pressure rod 33 to be pressed on the film discharging roller 9, so that the lifting beam 18 and the film discharging roller 9 are enabled to rotate synchronously. Meanwhile, the left transverse cutting air knife 22, the left gluing mechanism 23, the left slide seat fixing seat 24, the right transverse cutting air knife 29, the right gluing mechanism 30 and the right slide seat fixing seat 31 are driven to descend, the left transverse cutting air knife 22 and the right transverse cutting air knife 29 are pressed on the film of the film discharging roller 9, the stepping motor 32 rotates to pull the transverse cutting synchronous belt 21, so that the left slide seat fixing seat 24 drives the left gluing mechanism 23, the left slide seat fixing seat 24 slides leftwards, the right slide seat fixing seat 31 drives the right transverse cutting air knife 29, and the right gluing mechanism 30 slides rightwards, the films of the two film discharging rollers 9 are cut and separated, and meanwhile, a glue tape is coated on the back end edge of the cutting surface.

And secondly, discharging the finished product reel 4, and enabling the bearing frames 10 at two ends to return.

After the first step of cutting and gluing is completed, the lifting cylinder 14 extends out, the V-shaped block 12 is pushed to ascend, the two ends of the finished product reel 4 are lifted, the pushing cylinder 13 extends out, the V-shaped block 12 and the finished product reel 4 are pushed to swing rightwards, as shown in fig. 2, the lifting cylinder 14 retracts after the finished product reel 4 is in place, the two ends of the finished product reel 4 fall onto the discharging slide rail 15, and the finished product reel slides down to the discharged material storage table 8 along the slope of the discharging slide rail 15 to complete discharging. The push-out cylinder 13 retracts.

When the two ends of the finished product reel 4 are lifted, the two-end supporting bearing frame 10 returns to the initial position under the action of the supporting bearing frame return spring 11, the initial position is matched with the falling position of the to-be-wound reel 2, and when the to-be-wound reel 2 falls, the to-be-wound reel 2 and the film discharging roller 9 have pre-pressure, so that the to-be-wound reel 2 and the film discharging roller 9 are ensured to rotate synchronously.

And thirdly, when the winding shaft 2 falls down for feeding, the lifting beam 18 is reset.

When the second step is carried out, the film discharging roller 9 rotates synchronously with the lifting beam 18 and the to-be-wound roll 2 on the film roll bracket 25, when the film discharging roller rotates to the two ends of the to-be-wound roll 2 to be contacted with the two-end supporting shaft bearing bracket 10, the to-be-wound roll 2 is fed to the two-end supporting shaft bearing bracket 10 and rotates synchronously, at the moment, the cut rear part of the film is separated, the cut front part of the film is adhered to the surface of the to-be-wound roll 2 which is fed completely under the action of glue viscosity, and the film discharging roller 9 and the to-be-wound roll are automatically started along with the synchronous rotation.

Meanwhile, the telescopic double-shaft cylinder 26 retracts, the lifting cylinder 19 extends, the lifting beam 18 leaves the film discharging roller 9, and the lifting beam 18 returns under the action of the swing rod spring 17. The stepping motor 32 rotates reversely to pull the transverse cutting synchronous belt 21 reversely, so that the left slide seat fixing seat 24 drives the left gluing mechanism 23, the left slide seat fixing seat 24 slides rightwards, the right slide seat fixing seat 31 drives the right transverse cutting air knife 29, and the right gluing mechanism 30 slides leftwards to return to the initial position.

At this time, the system state returns to the state before the first step, and the output signal jump signal of the coil full stroke switch 39 at the two ends is waited to appear.

The invention adopts PLC as a core controller, wherein a travel switch, each state signal are input, each electromagnetic valve and a stepping motor are output, and the PLC is realized by adopting logic programming.
