The second reel member 2 includes a take-up reel 21, a take-up driver (not shown), and a take-up roll 22. The structure and operation principle of the winding shaft 21, the winding driver and the winding roll 22 are the same as those of the unwinding shaft 11, the unwinding driver and the winding roll 12, and the description thereof is omitted. In a specific setting, the unwinding shaft 11 is parallel to the winding shaft 21, so that the unwinding roll 12 is parallel to the receiving roll 22, and a space is formed between the unwinding roll 12 and the receiving roll 22.
The roll 3 includes a material strip 31, and the material strip 31 is integrally connected to the feeding roll 12 and the receiving roll 22, that is, the material strip 31 is a material strip released from the feeding roll 12 and a material strip wound by the receiving roll 22.

Example two
With continuing reference to fig. 1 and 2, fig. 2 is a flowchart of a roll diameter calculation method according to a second embodiment. The roll diameter calculating method in the embodiment includes a first roll member 1, a second roll member 2, and a roll material 3, and the first roll member 1 and the second roll member 2 cooperate to wind and unwind the roll material 3. It also includes the following steps:
and S1, the detection shaft 4 detects the coil 3 to obtain the coiling and uncoiling length L of the coil 3 in unit time.
S2, obtaining the rotation angle W of the first reel member 1 in unit time1Second reel member2 angle of rotation W per unit time2
S3, calculating the roll diameter D of the first reel member 1 in unit time1The winding diameter D of the second winding shaft member 2 in unit time2
The winding length L of the coil stock 3 per unit time is detected by the detection shaft 4, and the winding diameter D of the first winding shaft 1 and the second winding shaft 2 per unit time is indirectly calculated and measured1And D2And furthermore, automatic control of winding and unwinding is realized according to the real-time winding diameter, and the whole method is simple and accurate, is easy to improve on the existing winding and unwinding device, and is suitable for popularization.
Referring to fig. 1 and 2 again, further, in step S1, the detecting shaft 4 detects the coil stock 3 to obtain the winding/unwinding length L of the coil stock 3 in unit time, and includes the following sub-steps:
s11, winding the coil stock 3 around the detection shaft piece 4, and synchronously rotating the detection shaft piece 4 along with the winding and unwinding of the coil stock 3.

Referring to fig. 1 and 2 again, for convenience of understanding, the roll diameter calculating method in the present embodiment will be further described with reference to the roll diameter calculating device in the first embodiment. In step S111, the tape 31 of the roll 3 is wound around the detection shaft 41 of the detection shaft member 4. In step S12, the pressing shaft 51 of the pressing shaft 5 presses the tape 31 in cooperation with the detection shaft 41, increasing the friction between the detection shaft 41 and the tape 31. In step S113, the detection shaft 41 rotates synchronously with the retraction of the tape 31. In this manner, in step S11, the storage length L of the tape 31 can be converted into the arc length of the cross-sectional circle of the detection shaft 41 corresponding to the rotation angle of the detection shaft 41. Since the above-mentioned conversion process is a dynamic process, and is not an instant process, it is necessary to rotate the detection shaft 41 by a certain angle after a unit time, for example, 10s is rotated by 60 degrees, and the arc length of the cross-section circle of the detection shaft 41 corresponding to 60 degrees is equal to the storage length L of the tape 31 within 10 s.
In step S12, the diameter D of the detection shaft 41 can be measured directly by a scale or the like3. When the detecting shaft 41 rotates, the magnetic encoder or other angle sensor is arranged corresponding to the cross section circle of the detecting shaft 41, so that the rotating angle of the detecting shaft 41 can be measured in real time, and further the rotating angle W of the detecting shaft 41 in unit time can be obtained3. The detection shaft 41 rotates 360 degrees to form a complete circle. The circumference of a complete circle is expressed as D pi, and the rotation W of the detection shaft 41 in unit time3The length of the arc corresponding to the angle is equal to the length L of the tape 31, so that a corresponding formula can be listedFurther obtain the formula of the length of the material belt 31 in unit time
In step S2, the rotation angle W of the unreeling shaft 11 of the first reel member 1 is obtained in a unit time1And obtaining the rotation angle W of the take-up shaft 21 of the second reel member 22And obtaining the rotation angle W of the detection shaft 41 per unit time3The above-mentioned methods are consistent and will not be described in detail herein. The unwinding material 12 of the first reel member 1 is sleeved on the unwinding shaft 11, and the rotation angles of the unwinding material 12 and the unwinding shaft 11 in unit time are consistent; similarly, the winding material 22 of the second winding shaft 2 is sleeved on the winding shaft 21, and the rotation angles of the winding material 22 and the winding shaft 21 in unit time are consistent. The rotation angles of the unwinding shaft 11 and the winding shaft 21 in unit time are measured, and the rotation angles of the unwinding material 12 and the winding material 22 in unit time are also measured synchronously.
In step S3, the coil diameter D of the coil stock 12 per unit time1Angle of rotation W1Have the following relationship between:to obtain D1Is calculated byThe roll diameter D corresponding to the material roll 22 in unit time2Angle of rotation W2Have the following relationship between:to obtain D2Is calculated byThen the above-mentioned tape 31 length formula of receiving and releasing in unit timeCalculating to obtain the coil diameter of the uncoiled material 12 in unit timeThe roll diameter of the material roll 22 in unit timeThat is, in the case that the detecting shaft 41 is known, we only need to detect the real-time rotation angles of the unwinding shaft 11, the winding shaft 21 and the detecting shaft 41 in real time to obtain the roll diameter of the unwinding roll 12 and the winding roll 22 per unit time, that is, the real-time roll diameter. In practical application, the real-time rotation angle of the shaft is easy to realize, for example, the assembly of angle sensors such as a magnetic encoder and the like is enough, so that the calculation method can be simply modified in the existing equipment, the modification structure is simple, the calculation can be quickly realized, the detection result is accurate, and the stable automatic control of winding and unwinding is further ensured.

According to the winding diameter D of the first winding shaft member 1 in unit time1And the winding diameter D of the second winding member 2 per unit time2The rotational speeds of the first reel member 1 and the second reel member 2 are controlled, respectively.
The roll footpath of unit interval is the real-time roll footpath promptly, move backward along with time, the real-time roll footpath of blowing book 12 diminishes gradually, the roll footpath of receiving material book 22 enlarges gradually, if unreel axle 11 and rolling-up axle 21 rotate still with initial slew velocity, the coil stock 3 of the roll coil of 12 releases that real-time roll footpath diminishes gradually can't satisfy the winding speed of the roll coil of 22 that real-time roll footpath enlarges gradually, and then can make coil stock 3 be broken, then need correspond the slew velocity that increases unreel axle 11 this moment, or reduce the slew velocity of rolling-up axle 21, or synchronous increase unreel axle 11's slew velocity and reduce rolling-up axle 21 slew velocity.
Preferably, controlThe speeds of the material 3 to be wound and unwound from the first reel member 1 and the second reel member 2 are made to be the same. Specifically, the formulaIt can be seen that to control the length of the release strip 31 of the roll 12, the rotation angle W of the roll 12 needs to be correspondingly controlled1And a rotation angle W1The control of (1) needs to control the rotation speed of the discharging roll 12, the rotation speed of the discharging roll 12 is controlled by the rotation speed of the discharging shaft 11, and the rotation speed of the discharging shaft 11 is controlled by the discharging driver, that is, by the servo motor, so that the length of the discharging belt 31 of the discharging roll 12 can be controlled by only controlling the driving rotation speed of the servo motor. Similarly, the winding speed of the winding roll 22 can be controlled by controlling the driving rotation speed of the winding driver. Through the drive rotational speed complex regulation of unreeling driver and rolling driver, realize that the speed that control unreels material book 12 and releases material area 31 is unanimous with the speed that receives material book 22 and roll up material 33, when so avoiding material area 31 to be broken, also can guarantee that material area 31 can not the windrow, guarantees the normal operating of the equipment that has the receipts function of unreeling.
