Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the following examples are not intended to limit the present invention, and various combinations and substitutions between the examples may be made.
As shown in fig. 2 and 3, one embodiment of the present invention provides a coiler. The coiler includes a sleeve 10 for coiling the strip, and a sleeve attachment 12 provided on the outer surface of the sleeve 10. Wherein the sleeve 10 comprises a first sleeve end face and a second sleeve end face which are parallel; the first and second lateral faces of the sleeve attachment 12 are flush with the first and second sleeve end faces, respectively. That is, the sleeve appendage 12 completely covers the outer surface of the sleeve 10 in the direction of the axis L as shown in fig. 3. Thus, the sleeve attachment 12 having a sufficient width is provided on the sleeve 10, which can be adapted to strip steels of different widths.
The attachment sleeve 12 further includes a first end 14 and a second end 16 opposite the first end 14, the second end 16 protruding from the outer surface of the sleeve 10, and the upper surface of the attachment sleeve 12 is smoothly curved and smoothly transits from the outer surface of the sleeve 10 through the first end 14.
It should be appreciated that the sleeve attachment 12 described above may be integrally formed with the sleeve 10 for ease of manufacture. Alternatively, the sleeve attachment 12 may be provided on the surface of the sleeve 10, such as by a connector or adhesive, which may facilitate retrofitting of existing sleeves without the need to re-produce the sleeve, reducing manufacturing and fabrication costs.
Of course, it should also be understood that the sleeve attachment 12 may be made of the same material as the sleeve 10, or the sleeve attachment 12 may be made of a material having some flexibility, as the case may be, and the present invention is not limited thereto.
In the coiling machine related to the embodiment, the sleeve additional piece 12 at least partially protruding out of the outer surface of the sleeve 10 is arranged on the sleeve 10, and in the process of coiling the strip steel by the coiling machine, the sleeve additional piece 12 can be aligned to the strip head of the strip steel, so that the thickness difference between the strip head part and the sleeve 10 is reduced, the curvature mutation degree of the subsequent strip steel is reduced, and the generation probability of strip head marks is further reduced.
Referring again to fig. 2 and 3, according to one embodiment of the invention, the first edge 24 of the first end 14, the second edge 26 of the second end 16, and the axis L of the sleeve 10 are parallel to one another so that the second edge 26 can be aligned with the head of the strip.
According to one embodiment of the invention, the second end 16 comprises two parallel second edges 26, as shown in fig. 2, the side between the two second edges 26 being configured as a second end side wall, which lies in a plane defined by the second edges 26 and the axis L. In other words, the two second edges 26 are coplanar with the axis L, i.e. the second end side wall is perpendicular to the tangential direction of the connection point of the second end side wall and the sleeve 10, so that the taping head can be aligned.
As shown in fig. 2, 4 and 5, according to one embodiment of the invention, the sleeve appendage 12 covers a quarter of the outer surface of the sleeve 10 about the axis L. Of course, it is conceivable that the sleeve attachment 12 can also cover more than a quarter of the outer surface of the sleeve 10 about the axis L as shown in fig. 2. Alternatively, in another embodiment, the sleeve appendage 12 may also completely cover the outer surface of the sleeve 10, so as to obtain a more rounded outer surface.
According to one embodiment of the invention, the second end 16 protrudes 1mm from the outer surface of the sleeve 10. Alternatively, the second end 16 may protrude from the outer surface of the sleeve 10 by other heights according to different requirements, and only needs to be matched with the thickness of the steel strip.
As shown in fig. 4 and 5, according to an embodiment of the present invention, the coiler further comprises: a drive device, a tape head position detection device 18, and a control device. Wherein the drive device is connected with the sleeve 10 in a torque-transmitting manner so as to drive the sleeve 10 to rotate; a leading position detecting device 18 for determining the leading position of the strip steel; control means are connected to the drive means and the tape head position detection means 18, respectively, for adjusting the speed at which the drive means drives the sleeve 10 in rotation in dependence on the tape head position detected by the tape head position detection means 18.
That is, the control means adjusts the rotation speed of the sleeve 10 according to the position of the leading end of the strip so that the leading end is at the start of the coiling, and the second end 16 of the sleeve attachment 12 has a suitable distance to accelerate.
Referring again to fig. 4 and 5, in accordance with one embodiment of the present invention, the leading end position detecting device 18 includes a signal transceiver device 20 and a signal reflector device 22 that are aligned, and the leading end position detecting device 18 is configured to block signal transmission between the signal transceiver device 20 and the signal reflector device 22 when the strip passes between the signal transceiver device 20 and the signal reflector device 22.
Specifically, in one embodiment, the signal transceiver 20 may include a light source and a photocell, and the signal reflecting device 22 may include a mirror. The light source is used for emitting light beams to the signal reflection device 22, and the light beams are received by the photoelectric tube after being reflected by the signal reflection device 22. When the strip steel passes between the signal transceiver 20 and the signal reflection device 22, the strip steel blocks the transmission of the light beam, the photoelectric tube cannot receive the light beam irradiation, and a signal can be fed back to a user to judge the position of the strip head. Of course, the signal transceiver 20 may also emit signals such as electrical signals, and the invention is not limited thereto.
In another embodiment, the leading end position detecting device 18 may also include a signal emitting device and a signal receiving device which are aligned with each other, and the strip steel can block the signal transmission between the signal emitting device and the signal receiving device when passing between the signal emitting device and the signal receiving device.
Referring again to fig. 4 and 5, in one embodiment, the strip is fed to the sleeve by the strip transport 28, and the strip transport 28 passes through the leading end position detecting device 18 without obstructing the signal transmission between the signal transceiving device 20 and the signal reflecting device 22.
As shown in fig. 6, fig. 6 shows the length of the strip that is rolled using the improved coiler of an embodiment of the present invention that produces a head mark defect, and the length of the strip that is rolled using the existing sleeve that produces a head mark defect. Wherein the abscissa represents the sampling number (i.e., the sample collection amount), and the ordinate represents the length of the strip steel having the head print defect. It can be seen that the length of the strip with defects can be greatly reduced by using the coiler with the sleeve attachment 12 according to the invention for coiling the strip, and the average defect length can be reduced from 88.7 meters to 34.2 meters.
In another embodiment, the coiler is a galvanizing unit coiler.
The invention also provides a speed adjusting method of the coiling machine, which comprises the following steps: the remaining movement distance Deltal from the tape head to the contact position where the tape head is in contact with the sleeve 10 is calculated1And the remaining rotational distance Deltal of the attachment sleeve 122(ii) a Comparison of Δ l1And Δ l2，

Wherein α is the acceleration of the attachment sleeve 12, when the tape head reaches the head contact position, the second end sidewall of the attachment sleeve 12 is aligned with the tape head, and the rotational speed of the attachment sleeve 12 is v0。
The alignment of the side wall of the second end part and the strip head means that the strip head reaches the contact position of the strip head, and the coiling machine is about to coil the strip steel.
Calculating Δ l1And Δ l2The process comprises the following steps:
s3: starting the coiler and calculating or measuring the distance l of the movement of the head after passing the head position detection device 181Residual distance Deltal between tape head and tape head contact position1Is composed of
Δl1＝L1-l1，
At tape head movement distance l1While the sleeve attachment 12 is rotated over a distance l2Until the second end side wall is aligned with the tape head, the remaining rotational distance Δ l of the sleeve attachment 122Is composed of
Δl2＝L2-l2。
Specifically, according to one embodiment, step S2 further includes the sleeve attachment 12 accelerating at an acceleration α for a time t1Elapsed time t1The rear sleeve attachment 12 reaches a speed v0And at a velocity v0Uniform motion with time t2Then, then

according to one embodiment of the invention, the method comprises the following steps: when the second end sidewall is aligned with the tape head, the distance between the second end sidewall and the tape head is 0 to 80 mm.
According to one embodiment of the invention, the method comprises the following steps: if Δ L is positive, the rotational speed of the attachment sleeve 12 is reduced; if Δ L is negative, the rotational speed of the sleeve attachment 12 is increased; if Δ L is 0, the driving sleeve attachment 12 is driven at a speed v0And continuing to rotate.
Further, in one embodiment, the rotational speed of the collet attachment 12 is superimposed by an increment Δ L based on the value of Δ LvAnd repeating the above process for multiple times to obtain the increment delta corresponding to different delta L valuesvSo that the distance between the second end side wall and the tape head is in the range of 0 to 80mm when the second end side wall is aligned with the tape head. Thus, the increment Δ can be obtained after a plurality of testsvSo as to superimpose the increment delta exactly on the different values in the subsequent operationsvAnd the adjustment time is saved.
According to an embodiment of the invention, the coiler is a galvanizing unit coiler, the specific structure of a sleeve 10 of the coiler is shown in fig. 2, the structure of a conventional sleeve is optimized, a sleeve additional piece 12 which is approximate to a quarter of an arc is added and is spirally attached to the common sleeve, the thickness of the sleeve at the starting end (a second end part 16) is 1mm, the thickness of the sleeve at the tail end (a first end part 14) is 0, and the sleeve is gradually decreased, so that the thickness difference between the thickness of a strip head and the sleeve is reduced, the curvature mutation degree of subsequent strip steel is reduced, and the generation probability of the strip head mark is reduced.
The sleeve with the optimized structure has the problem of accurate positioning of the strip head of the strip steel and the sleeve additional part 12. Through field experiments, when the tape head is positioned within 0-80 mm behind the sleeve attachment 12, the tape head print defects are greatly improved; statistical analysis of the experimental data, the tape head was positioned 50mm behind the sleeve attachment 12 with a positioning accuracy of + -30 mm.
The positioning principle is as shown in fig. 4 and 5, firstly, the sleeve attachment 12 rotates to a point F, when the strip steel passes through the strip head position detection device 18, the strip head position detection device 18 detects a signal, the coiling machine rotates at a certain speed in a matching way, and when the sleeve attachment 12 rotates to a point E, the strip head is accurately positioned at a point B; the linear distance between the E point and the B point is 50 mm; the control precision is within +/-30 mm.
From the positioning point of view, the closer the opening position of the strip end position detecting device 18 (i.e., the position where the strip passes through the strip end position detecting device 18) is to the strip end contact position B, the better, but considering that the coiler needs a certain acceleration time from the standstill to the synchronization with the strip speed, the interval of 1.4m to 1.6m is suitable.
The movement speed of the strip steel is known as v0The acceleration of the coiler is α, and the distance from point D to point B is L1And the time t from the point D to the point B of the strip steel is as follows:
t＝L1/v0。
during the time t, it is necessary to control the clockwise rotation of the attachment sleeve 12 from the starting point F to the point E, and the acceleration takes place for a time t1The time of uniform motion is t2And then:
t＝t1|t2，
l1＝v0/α，

ΔL＝Δl1-Δl2，
At Δ l1As reference quantity,. DELTA.l2After PI calculation is carried out on the difference value Delta L of the feedback quantity, the output value is used as the increment Delta of the speed setting of the coilervAnd the speed input of the device is superposed, so that the accurate positioning is ensured.
Accurate positioning needs a certain time sequence control, the tape head positioning outputs an initial angle set value according to the inner diameter of the sleeve 10 and the coiling mode, the mandrel coils a preparation completion signal, the mandrel drives the sleeve to start rotating, and if the tape head position detection device 18 does not detect a tape head position signal within 30 seconds, the tape head positioning device automatically stops. When a signal is detected (that is, the tape head reaches the tape head position detection device 18), the mandrel angle self-positioning is triggered (that is, the second end 16 of the sleeve attachment 12 is positioned at point F shown in fig. 5), after the self-positioning is completed, the tape threading automatic step is started, when the tape head position detection device 18 detects a tape head position signal, the mandrel starts to synchronously rotate, the tape head hits a target area, the speed is increased, the tape head normally runs, and the tape head positioning is completed.
The coiling machine is adopted to coil the strip steel, and the length of the strip head print defect is obviously reduced; wherein the average length of the head print hand feeling defect is reduced from 88.7m to 34.2 m. FIG. 6 shows the comparison of the defect length of the tape head print of the coiler before and after the application of the present embodiment, the specification is 2.0mm, the steel grade is consistent, 18 rolls are randomly drawn out, and the change condition of the tape head print length is inspected.
