S11:: being ready in roller frame 310 wait fly to connect work beam batching to deposit in advance, such as can be once deposited in roller frame batching to deposit
Put it is multiple wait fly to connect work beam or connect work beam wait fly toward batching to deposit roller frame and increase by one by interval of preset time value, herein not
It is restricted.
S12: it is ready on unwinding device 10 wait fly to connect let off roll, i.e., on the first intermediate station 102 of unwinding device 10
Preparation pre-sets flying connecting joint wait fly to connect let off roll on the paper web wait fly to connect let off roll, usually can be used 50mm's
Water-soluble double-sided adhesive manufactures flying connecting joint on the paper web wait fly to connect let off roll.Wherein, using transport trolley when default
Between transport wait fly to connect let off roll to the first intermediate station 102, so that the connection of supercalender 1 carries out change of lap calendering operation.
S13: it is less than or equal in the length for detecting the remaining paper web on the current let off roll for unreeling and placing on station 101 pre-
If when length, when such as the length of the remaining paper web of current let off roll is 1000 meters, unreeling shaft coupling and disconnecting to current let off roll
Driving so that current let off roll by the automatic reduction of speed of normal work speed to flying to connect speed, fly to connect speed to be 40 ms/min, together
When control the paper web that the tension on the paper web that current let off roll is discharged discharges by the current let off roll under normal operating rate
On tension 20%-40%, meanwhile, control system control unreels lift lever decline, current let off roll is held up.
S14: control system, which further controls, unreels shaft coupling opening, so that devices for taking-up 30 drives current let off roll to be released
The paper web put continues to rotate, also, utilization unreels the tension that the locking device on lift lever keeps the paper web of current let off roll.
Meanwhile the double hook pull rod that batches of devices for taking-up 30 is moved along to batching station 301, it is secondary on double hook pull rod
Transmission coupling closure makes to batch the current work beam on station 301 to fly to connect speed rotation, even if batching current on station 301
Work beam is rotated with 40 ms/min of speed.
S15: it after unreeling lift lever and holding up current let off roll, is put wait fly to connect let off roll to be rolled by the first intermediate station 102
Volume station 101.After flying to connect let off roll and rolling into and unreel station 101, unreel shaft coupling closure, with drive be located at unreel station 101 to
Fly to connect the paper web of let off roll to fly to connect speed rotation, that is, unreel shaft coupling drive enter unreel station 101 wait fly to connect let off roll with
40 ms/min of speed rotation.
When sensor module 306 detects that the speed of the secondary drive shaft coupling of devices for taking-up 30 also reaches 40 ms/min
When, batch shaft coupling opening, double hook pull rod will be located at batch station 301 current work beam toward post-tensioning, will be on current work beam
It is sent in accumulator plant 312.
S16: unreeling cutting and blow and fly to connect roller and press to the paper web that current let off roll is reserved wait fly to connect let off roll, when light eye sense
The double-sided adhesive flying connecting joint for answering device to detect wait fly to connect let off roll has been bonded to the reserved paper of currently running current let off roll
After on width, unreels the cutter that cutting air blowing flies to connect on roller and cut off the paper web of current let off roll, while unreeling cutting and blowing and flying to connect
Gas blow pipe opening on roller is blown, and the paper scrap generated in cutting process is avoided to enter press polish area.So far, wait fly to connect let off roll
On paper web initially enter calendering device carry out press polish.
Meanwhile batching lift lever and will batch station 301 wait fly to connect work beam to be put into from the second intermediate station 302, batch shaft coupling
Device closure drives and connects speed operation wait fly to connect work beam with the winged of 40 points/minute.
S17: the sheet feeding with cutter is opened, and toward Forward, the paper web on current work beam is pressed to wait fly
Work beam is connect, and the cutter on sheet feeding cuts off the paper web on current work beam, while on sheet feeding
Gas blow pipe is pressed on the paper web on current work beam wait fly to connect on work beam.
S18: unreeling lift lever and unreel on sky roll bracket 109 having unreeled the empty roller finished and put into, with will be empty by driving
Roller is hung away.
Meanwhile the big paper roll on current work beam is moved to next work station by the double hook pull rod of devices for taking-up 30.
So far, entirely flying to connect reel change automatically terminates.
In conclusion it should be readily apparent to one skilled in the art that supercalender provided by the invention, by being put wait fly to connect
Flying connecting joint is made on winding up roller, when the length of the remaining paper web of current let off roll is less than or equal to preset length, using flying to connect
Connector will be wait fly to connect the paper that let off roll is Nian Jie with current let off roll, and the current let off roll of row cutting is discharged again after being bonded successfully
Width makes wait fly to connect let off roll automatically into calender progress press polish, and realization carries out change of lap in non-stop-machine situation, automates journey
Degree is high, can be shortened the change of lap time, improves the change of lap efficiency of supercalender.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
