A plurality of idler wheels 6 are arranged between the discharging motor 1 and the receiving motor 2 at intervals to reverse the film 100 transmission.
Fig. 2 is a schematic structural view of a first buffer assembly provided in an embodiment of the present utility model, and fig. 3 is a schematic structural view of a second buffer assembly 5 provided in an embodiment of the present utility model, as shown in fig. 2 and 3, the first buffer assembly 4 and the second buffer assembly 5 include a cylinder 41, a movable pulley 42, an inductor 43, and two receivers 44, wherein an output end of the cylinder 41 is in transmission connection with the movable pulley 42 and the inductor 43, and the two receivers 44 are spaced and fixedly arranged along a displacement direction of the inductor 43 so as to receive an induction signal of the inductor when the two receivers are opposite to the inductor 43. The displacement direction of the sensor 43 means a direction in which the sensor 43 moves by the driving of the cylinder 41. The control assembly is electrically connected with the discharging motor 1, the receiving motor 2, the driving assembly 3, the first buffer assembly 4 and/or the cylinder 41 of the second buffer assembly 5 respectively. When the film passes around the first buffer assembly 4 and/or the second buffer assembly 5, it means that the film passes around the movable pulleys 42 in the two buffer assemblies.
More specifically, for example, in one case, the first buffer assembly 4 and the second buffer assembly 5 each include a bracket, the cylinder 41 body is fixed on the bracket, the output shaft of the cylinder 41 is connected with one of the movable pulley 42 and the sensor 43, the movable pulley 42 is connected with the sensor 43, the two receivers 44 are fixedly connected on the bracket at a distance S, and when the cylinder 41 drives the movable pulley 42 and the sensor 43 to move along the first direction, the sensor 43 can pass through the positions of the two receivers 44 successively. Further, when the film is wound around the movable pulley 42, the extending direction of the film on both sides of the movable pulley 42 is the same as the displacement direction of the movable pulley 42, and in this case, the process of calculating the winding diameter is the simplest. Of course, the connection relation in the cache module is not limited thereto as long as the corresponding function thereof can be realized.
For the material winding device provided by the embodiment of the utility model, when the film 100 is wound and unwound, firstly, the material winding and unwinding are respectively sleeved on the output ends of the unwinding motor 1 and the material winding motor 2, wherein the film winding is sleeved on the unwinding. Then, the cylinder 41 of the first buffer assembly 4 drives the movable pulley 42 to move upwards, the film roll on the unreeling roll rotates at a certain angular speed, and the film 100 is released (at this time, the driving assembly 3 does not work), so that a section of film 100 is buffered by the first buffer assembly 4. At this time, the discharging motor 1 simultaneously provides reverse torque (and rotates during buffering, and does not rotate any more after buffering is finished), so that the film 100 is in a tensioned state. In this process, the cylinder 41 of the first buffer assembly 4 drives the movable pulley 42 and the inductor 43 to move upwards, the inductor 43 sequentially passes through the two receivers 44, the two receivers 44 respectively receive the induction signals of the inductor 43 and transmit the signals to the control assembly, meanwhile, the control assembly receives the rotating angle of the discharge motor 1 in this time period, the radius of the discharge coil and the corresponding angular speed and other data of the discharge coil are calculated after processing, the control assembly can regulate and control the angular speed of the discharge motor 1 in real time, and the tension of the film 100 in the discharge process is ensured to be constant and the film is controlled to travel at a relatively constant speed (discharge buffer).
Then, the driving component 3 works to drive the film 100 to walk (namely, the film walking stage), at this time, the driving force of the driving component 3 is greater than the force provided by the first buffer component cylinder, the cylinder 41 of the second buffer component 5 drives the corresponding movable pulley 42 to move upwards, and the cylinder 41 of the first buffer component drives the movable pulley 42 to move downwards (the discharging motor 1 and the receiving motor 2 do not rotate), so that the film 100 is buffered to the second buffer component 5 again.
Finally, the take-up motor 2 drives the take-up reel to rotate, so that the film 100 is wound up with a certain tension and speed (at this time, the driving assembly 3 is not operated). At this time, the film 100 pulls the cylinder 41 of the second buffer assembly to move downward, and the buffered film 100 is released and recovered onto the receiving roll. Similarly, in this process, the air cylinder 41 of the second buffer assembly drives the inductor 43 to move downwards, the inductor 43 sequentially passes through the two receivers 44, the two receivers 44 respectively receive the induction signals of the inductor 43 and transmit the signals to the control assembly, meanwhile, the control assembly receives the rotation angle of the discharge motor 1 in this time period, calculates the radius of the discharge coil and the corresponding angular velocity and other data after processing, and the control assembly can regulate and control the angular velocity of the receiving motor 2 in real time, so as to ensure that the tension of the film 100 is constant and the receiving is carried out at a relatively constant speed in the receiving process.
That is, the winding device provided by the embodiment of the utility model can determine the radius of the material receiving roll and/or the material discharging roll in real time, so that the angular speed of the material discharging motor 1 or the material receiving motor 2 during material receiving and discharging is adjusted in real time, the film is ensured to walk/receive at a relatively constant speed and tension, the film tension is maintained to be stable, and the film is prevented from being excessively loosened/tightened.
Similarly, when the coil stock device has only one buffer component, the first buffer component 4 or the second buffer component 5. Specifically, when the first size-reducing component is located between the driving component 3 and the unreeling roll, the radius of the unreeling roll and the corresponding angular speed and other data of the unreeling roll are calculated in the buffer memory in the above manner, so that the angular speed of the unreeling motor 1 when the unreeling roll is regulated in real time, and the description is omitted. When the second buffer assembly 5 is located between the driving assembly 3 and the receiving roll, the radius of the receiving roll and the corresponding angular velocity and other data of the receiving roll are calculated in the above manner, so that the angular velocity and the film tension of the receiving motor 2 are adjusted in real time when the receiving roll is retracted, and the detailed description is omitted. And when the first buffer assembly 4 and the second buffer assembly 5 are both arranged, the radius of the unreeling roll and the reeling roll and the corresponding angular speed and other data can be calculated at the same time, so that the angular speeds of the unreeling motor 1 and the reeling motor 2 during reeling and unreeling of the material rolls are adjusted in real time.
In one implementation of the utility model: calculating the radius of the unreeling roll:
when the sensor 43 on the first buffer assembly 4 passes through the two receivers 44 successively, the sensing signals received by the two receivers 44 are t 1 and t 2 respectively, the interval between the two receivers 44 is S 1 (which is a fixed value), and the radius of the corresponding unreeling roll is R 1. The discharging motor 1 is provided with an encoder which records that the rotating angle of the discharging motor at the time of t 1 and t 2 is alpha, the corresponding rotating arc length is L 1, namely the buffer length of the film 100 is L 1 (which is equivalent to 2 times of the distance between the two receivers 44), so that,
L1＝2*S1； (1)
2π*R1*α/360°＝2*S1； (2)
From formulas (1) and (2), R 1＝(360°/α)*S1/pi can be known, so that the radius R 1 of the unreeling roll is calculated in real time. In the period from t 1 to t 2, the discharging motor 1 collects α and transmits the α to the control component, the control component processes and obtains the real-time radius R 1 of the corresponding discharging roll and the angular velocity of the corresponding discharging motor 1 (the product of the angular velocity of the motor and the radius of the discharging roll is the constant discharging roll linear velocity to be controlled), and the control component regulates and controls the angular velocity of the discharging motor 1 in real time, so that the film linear velocity is constant, and the film movement speed is constant and the tension is stable in the discharging process.
Radius calculation for the receiving rolls:
When the sensor 43 on the second buffer assembly 5 passes through the two receivers 44 successively, the sensing signals received by the two receivers 44 are t 3 and t 4 respectively, the interval between the two receivers 44 is S 2 (which is a fixed value), and the radius of the corresponding material receiving roll is R 2. The material receiving motor 2 is provided with an encoder which records the rotation angle beta of the material receiving motor 2 in the time of t 3 and t 4, and the corresponding rotation arc length is recorded as L 2, namely the rolling length of the film 100 is L 2 (which is equivalent to 2 times of the distance between the two receivers 44), so that,
L2＝2*S2； (3)
2π*R2*β/360°＝2*S2； (4)
From formulas (3) and (4), R 2＝(360°/β)*S2/pi can be known, so that the radius R 2 of the receiving roll can be calculated in real time. In the period from t 3 to t 4, β is collected by the receiving motor 2 and is transmitted to the control component, the control component obtains the real-time radius R 2 of the corresponding receiving roll and the angular velocity of the corresponding receiving motor 2 (the product of the angular velocity of the motor and the radius of the receiving roll is the constant linear velocity of the unreeling roll to be controlled) through processing, and the control component regulates and controls the angular velocity of the receiving motor 2 in real time, so that the linear velocity of the film is constant, thereby ensuring that the moving velocity of the film is constant and the tension is kept stable in the receiving process.
It is easy to understand that by calculating the radius of the unreeling roll and the reeling roll, the angular speed of the unreeling motor 1 and the reeling motor 2 can be controlled in real time, so that the running speed of the film 100 during unreeling of the material roll is controlled, the sizes of the reeling roll and the unreeling roll can be accurately judged, a new material roll can be timely replaced, and stable and continuous feeding and reeling of the film 100 are ensured. In addition, the first buffer assembly 4 and the second buffer assembly 5 buffer through the air cylinder 41, and the tension of the film 100 in the film feeding stage can be precisely controlled by controlling the force of the air cylinder 41, so that the influence on processing caused by the tension change of the film 100 due to the asynchronous motor angular speed is prevented. And through setting up the second buffer memory subassembly, still be convenient for receive the material that the material roll can be even receive, further still be convenient for receive the film that the material roll was retrieved and carry out reuse.
It should be noted that the processing of the film 100 may be performed between the discharging motor 1 and the receiving motor 2. Specifically, the processing of the film 100 is performed by a laser processing device or other processing device on a horizontal film section corresponding to the front or rear of the driving assembly 3, at which time the corresponding film 100 is stationary, and the first buffer assembly buffers the next film 100 while receiving the last film 100. Therefore, it is necessary to ensure that the film 100 is buffered and wound up by the first buffer assembly 4 during the processing of the film 100, and ensure the processing continuity and processing efficiency of the film 100. In addition, the device is suitable for the periodic travel of the film 100, wherein the distance of the periodic travel of the film 100 is not less than twice the distance between the two receivers 44. In addition, during use of the movable pulley, the extending direction of the films 100 on both sides of the movable pulley 42 is the same as the displacement direction of the movable pulley 42.
When the discharge is buffered, the torque applied by the discharge motor 1 is controlled to be larger than the tension (wherein the torque is controlled by current).
In another implementation of the utility model, the radius for the unwind is calculated:
The angular speed of the discharging motor during each discharging is omega 1, the distance between the two receivers is S 3, the radius of the discharging roll is R 3, the time difference that the two receivers respectively sense the sensing signals of the sensors is Deltat 1, therefore,
v1＝S3/△t1； (5)；
v1＝R3*ω1； (6)；
Wherein v 1 is the linear speed of the discharge coil, and R 3＝(S3/△t1)/ω1 is known by formulas (5) - (6), so that the radius R 3 of the discharge coil and the corresponding angular speed of the discharge motor 1 are calculated in real time. In the period of Δt 1, the discharging motor 1 collects ω 1 and transmits the ω 1 to the control component, the control component obtains the real-time radius R 3 of the corresponding discharging roll and the angular velocity of the corresponding discharging motor 1 through processing, and the control component regulates and controls the angular velocity of the discharging motor 1 in real time, so that the linear velocity of the film is constant, the film moving speed is constant in the receiving process, and the tension is stable.
Radius calculation for the receiving rolls:
The angular speed of the material receiving motor is omega 2 when receiving materials each time, the distance between the two receivers is S 4, the radius of the material receiving roll is R 4, the time difference that the two receivers respectively sense the sensing signals of the sensors is Deltat 2, therefore,
v2＝S4/△t2； (7)；
v2＝R4*ω2； (8)；
Wherein v 2 is the linear speed of the receiving roll, and R 4＝(S4/△t2)/ω2 is known by formulas (7) - (8), so that the radius R 3 of the discharging roll and the corresponding angular speed of the receiving motor 2 are calculated in real time. In the period of Δt 2, the discharging motor 1 collects ω 2 and transmits the ω 2 to the control component, the control component processes the ω 2 to obtain a real-time radius R 4 of the corresponding discharging roll and an angular speed of the corresponding receiving motor 2, and the control component regulates and controls the angular speed of the receiving motor 2 in real time to make the linear speed of the film constant, thereby ensuring that the film movement speed is constant and the tension is stable in the receiving process.
The cylinder 41 may be a rodless cylinder, for example, which has a small installation space and high accuracy.
