Description
Technical field
The utility model relates to cold rolling rewinding unit and is with steel to have the problem of belt end seal in coiling process, takes the lead in particularly a kind of motion and the control device of soft jaw location.
Background technology
" belt end seal " is exactly in the strip coiling process, under the effect of coiling tension, stays the horizontal impression of spacing rule owing to the thickness of band itself on the band steel.Use the cold rolling rewinding unit of ordinary cartridge, the band belt end seal of its production is apparent in view, and length can reach tens meters when serious, has a strong impact on strip quality.Adopt band resilient sleeve (being commonly called as rubber bush) to batch in the flat cold-rolled sheet production process, reached and eliminated the impression (folding line) that the spool secter pat causes thin plate, but the end can be eliminated thin plate self and taken the lead impression that thin plate is caused.Occurred adopting the sleeve that has soft jaw (soft groove) at present, soft jaw zone material is softer, when taking the lead to be pressed in the jaw zone, can effectively solve the belt end seal problem, and this is hot issue and the technical barrier of studying both at home and abroad.
General rewinding production line does not have takes the lead and soft jaw positioning function, and minority has the production line of this function, its complex structure, and the hardware cost height is not easy to safeguard, has certain defective.
Summary of the invention
The purpose of this utility model provides that a kind of hardware configuration is simple, algorithm is reliable, precision is high, can solve and take the lead in a kind of motion of belt end seal problem and the control device of soft jaw location.
The purpose of this utility model is achieved in that takes the lead in a kind of motion and the control device of soft jaw location, it is characterized in that: a soft jaw is arranged batching on the sleeve; Set A, B, C, E, F point on the sleeve batching, the C point is batching the Far Left of sleeve, the C point has jaw detection and localization switch, E, F point respectively the top of batching sleeve with bottom, A point soft jaw and take the lead joining when batching down, the B point on when batching soft jaw with take the lead joining, the A point is on F point right side, the B point is on E point right side, last bottom pinch roll clamping band steel bisector constitutes relative horizontal line with the C point, pinch rolls outlet has the feeding guide plate up and down, and the D point is provided with and takes the lead sense switch on the feeding guide plate; Batching sleeve motor, last bottom pinch roll and detection and localization switch is electrically connected with control module.
After starting the coiling machine spool and batching sleeve and batched certain angle, on rotate counterclockwise when batching, under clockwise rotate when batching, confirm behind the soft jaw that through soft jaw detection and localization switch the soft jaw of reel is parked in jaw start bit F point (on batch) or E point (batching down) at the C point, so far soft jaw start bit positioning step is finished;
On when batching, control feeding guide plate is upwards parallel with B point tangent line, takes the lead by last bottom pinch roll at the uniform velocity mobile to upper left B point along the feeding guide plate; Under when batching, control feeding guide plate is parallel with A point tangent line downwards, takes the lead that the A point is at the uniform velocity mobile to left down by last bottom pinch roll;

Take the lead in a kind of motion and the control step of soft jaw location by soft jaw initial alignment step and soft jaw with take the lead alignment procedures:
Fig. 2 explanation: operating personnel press that " " button enters step 110 jaw positioning starting program to soft jaw initial alignment, then enters control step 111, and coiling machine rotates; When be contained on the reel reflector be contained in the optoelectronic switch that batches on the frame on time, soft jaw puts in place and detects step 112 and finish, otherwise soft jaw puts in place and detects step 112 and constantly detect photoelectric switching signal; After step 112 is finished, trigger coiling machine encoder to count function, begin to count long step 113, setting up procedure 114 subsequently, and soft jaw is to shifting to an earlier date the parking stall not; When meter length puts in place, step 115 speed 0, reel is even to slow down, and whether step 116 detection speed is to 0, and to 0, soft jaw initial alignment is parked in desired jaw initial bit to end step 117, otherwise continues execution in step 116 detection speeds to 0.
Fig. 3 explanation: soft jaw with take the lead to aim at flow process from step 120, enter step 121, whether detection takes the lead sense switch 3 on the feeding guide plate in unit self-threading tape process, less than, continuation; Arrive, enter step 122, coiling machine encoder to count function triggers, and carry out step 123, and whether encoder to count arrives is set the position, less than continuing step 123, arrives, and enters step 124, and coiling machine begins to quicken to rotate.Enter step 125, at this moment, coiling machine speed is regulated beginning automatically, with
Be reference quantity,
Be feedback quantity, to its difference
Carry out the PI computing, the increment that output valve is set for coiling machine speed
Enter step 126, will
The coiling machine speed setting value is added to.Enter step 127, on the reel soft jaw with take the lead to arrive simultaneously overlapping bit, and both linear velocities are identical.Enter step 128, coiling machine speed is regulated and is withdrawed from.Enter step 129, withdraw from soft jaw automatically and take the lead alignment procedure.
