Referring to Figures 1 and 2, the present invention has an edge and tension controlled roll-to-roll transfer system for providing transport of a film 90 along a machine direction D _M and winding the film 90. The roll-to-roll (R2R) transmission system is mainly defined by two idle wheels and a dancer roll in a three-wheel two-pitch setting. The transmission mechanism of the tension and edge controlled roll-to-roll transmission system includes a swing wheel 10, two idle rolls 21, 22, and two linear actuating units 51, 52. The oscillating wheel 10 has an axle 11 that extends axially through the oscillating wheel 10. The two idlers 21, 22 are a first idler 21 and a second idler 22 for supporting the film 90 and changing the direction of the film 90. When the film 90 is transported, the first idler 21 and the second idler 22 are free to rotate at a fixed height position. In Fig. 1, only the two idlers 21, 22 of the roll-to-roll transfer system and the portion of the oscillating wheel 10 are depicted, and the power members for providing the take-up and roll drive are omitted.

The first idler gear 21 and the second idler gear 22 are disposed on two adjacent sides of the swing wheel 10. In the present embodiment, the first idler gear 21 is disposed adjacent to the swing wheel 10 and is located at a relative position on the upstream side of the transport direction D _M . Further, the second idle gear 22 is disposed adjacent to the swing wheel 10 and is located at a relative position on the downstream side of the transport direction D _M .

Referring to FIG. 3, the roll-to-roll transmission system with tension and edge control of the present invention further includes an edge sensing unit 30. The edge sensing unit 30 is adjacent to the first idler 21 or the second idler 22 disposed on the downstream side of the transmission direction D _M and spans an edge 91 of the front and back sides of the film 90 to The position of the edge 91 of the film 90 is sensed. In practice, the edge sensing unit 30 is disposed on the second idler 22 on the downstream side of the transport direction D _M to more accurately sense the position of the edge 91 of the film 90. Specifically, the edge sensing unit 30 is mounted on a fixing member adjacent to the second idler gear 22 and extends above the second idler gear 22 without being in contact with the film 90. Thereby, the edge sensing unit 30 senses the position of the edge 91 of the film 90 to output an edge sensing value E _D . As for the detailed operation of the edge sensing unit 30, please refer to the following description.

Referring to FIG. 4 , the roll-to-roll transmission system with tension and edge control further includes two force sensing units 41 , 42 , which are a first power sensing unit 41 and a second power sensing unit 42 respectively. They are disposed on opposite sides of the axle 11 to detect the force on both sides of the axle 11. The first power sensing unit 41 or the second power sensing unit 42 may be a load cell, or a load cell. Thereby, the first force sensing unit 41 and the second force sensing unit 42 respectively detect the magnitude of the force on both sides of the axle 11 to correspondingly output a first power sensing value F _S1 and a second force. The sensed value F _S2 . For detailed operation of the two force sensing units 41, 42, please refer to the following description.

Referring to FIG. 5 and referring to FIG. 1, the roll-to-roll transmission system with tension and edge control of the present invention further includes a control unit 60. The control unit 60 can be a microcontroller or a microprocessor with computing power, but is not limited thereto. The control unit 60 receives the edge sensing value E _D output by the edge sensing unit 30 and the first power sensing value F output by the first power sensing unit 41 and the second power sensing unit 42 _S1 and a second force sensing value F _S2 . The control unit 60 further performs an operation and processing on the received edge sensing value E _D , the first power sensing value F _{S1 ,} and the second power sensing value F _S2 to output a first power control command value.

For the detailed operation of the control unit 60 for the arithmetic processing of the sensing values E _D , F _S1 , F _S2 and the output of the power control command values F _CM1 , F _CM2 , please refer to the following description. It is worth mentioning that the power control command values F _CM1 , F _CM2 output by the control unit 60 only control the linear actuating units 51, 52 with a schematic expression, that is, omitted in FIG. 5 to drive the linearities. The drive circuit of the units 51, 52 is actuated with the drive member.

Referring to Figures 6A and 6B, the edge control of the film 90 will be described. As described above, the edge sensing unit 30 is preferably disposed on the second idler 22 on the downstream side of the transport direction D _M . The film 90 is shown as being unshifted during transport, and the film 90' is indicative of an offset in transmission. When the edge sensing unit 30 detects that the film 90 is not offset on the second idler 22, it indicates that the edge 91 of the film 90 is transmitted on an edge reference value E _D0 .

In the present invention, the edge sensing unit 30 detects that the edge 91 of the film 90 and the lowermost edge of the second idler 22 are an edge sensing value E _D , and compares the edge sensing value E _{D .} The relative positional relationship with the edge reference value E _D0 is used to determine whether or not the film 90 is shifted, and the magnitude of the offset occurs. As shown in FIG. 6A, when the film 90' is offset in one direction, the edge sensing unit 30 detects the edge 91 of the film 90' and the lowermost edge of the second idler 22 as the edge. The measured value E _D , so the amplitude of the film 90 offset is an edge offset value ΔE _D . The magnitude of the edge offset value ΔE _{D is} the difference between the edge sensing value E _D and the edge reference value E _D0 , that is, ΔE _D =E _D −E _D0 . Similarly, in FIG. 6B, when the film 90 is offset in the other direction, the edge sensing unit 30 also detects the edge sensing value E _D and compares with the edge reference value E _D0 to obtain another One of the edge offset values ΔE _D .

It should be noted that in the two embodiments of FIG. 6A and FIG. 6B, the edge reference value E _D0 is used as a reference value, and then the difference between the edge sensing value E _D and the edge reference value E _D0 is calculated. Information on the offset or offset of the film 90 and offset can be detected. Specifically, if ΔE _D = E _{D -} E _D0 is positive, the direction in which the film 90 is shifted is as shown in FIG. 6A , and if ΔE _D = E _{D -} E _D0 is negative, it means that The direction in which the film 90 is offset is as shown in Fig. 6B. Thus, the direction of the offset of the film 90 and the magnitude of the offset can be determined based on the positive and negative values and the magnitude of the edge offset value ΔE _D .

Referring to the embodiment shown in FIG. 7A to FIG. 7D, it is explained how the roll-to-roll transmission system with tension and edge control of the present invention can perform edge and tension control on the film 90 by means of edge compensation and tension compensation. Specifically, in the embodiment shown in FIGS. 7A to 7D, the vertical direction of the first linear actuating unit 51 and the second linear actuating unit 52 perpendicular to the transport direction D _{M will be} transmitted. The amount of movement of the D _T up or down compensates for edge and tension control of the film 90.

As shown in Fig. 7A, in the first embodiment, the film 90 is not displaced during the transfer and the tension is balanced. In this state, it is assumed that the first linear actuating unit 51 is controlled to drive the position of the oscillating wheel 10 at a first origin position P ₁₀ , and the second linear actuating unit 52 is controlled to drive the swing. The position of the wheel 10 is a second origin position P ₂₀ . The position of the first origin position P ₁₀ and the position of the second origin position P ₂₀ are the same, so when the film 90 acts on the swing wheel 10 for transmission, the swing wheel 10 rotates horizontally. In order to maintain the film 90 unbiased and tension balanced.

As shown in Fig. 7B, in the second embodiment, the film 90 is not displaced during the transfer, but the tension is out of balance. Compared with FIG. 7A, the edge and the tension are balanced, and in this state, the control unit 60 controls the first linear actuating unit, assuming that the film 90 is excessively subjected to the upward direction of the vertical direction D _{T .} 51 moves upwardly with the second linear actuating unit 52 to provide tension compensation. More specifically, the control unit 60 controls the first linear actuating unit 51 to move upward from the first origin position P ₁₀ to a first moving position P _1U , and the difference between the two positions is defined as a first A compensation distance ΔP ₁ . At the same time, the control unit 60 controls the second linear actuation unit 52 to move upward from the second origin position P ₂₀ to a second movement position P _2U , and the difference between the two positions is defined as a second compensation distance ΔP. ₂ . Since in the embodiment, the film 90 is only unbalanced by the tension and no offset occurs, the first compensation distance ΔP ₁ is the same as the second compensation distance ΔP ₂ , that is, ΔP ₁ = ΔP ₂ .

Since the first compensation distance ΔP ₁ is the same as the second compensation distance ΔP ₂ , the first linear actuation unit 51 and the second linear actuation unit 52 move upward to drive the oscillating wheel 10 horizontally upward. The movement is tension compensated to maintain the balance of the edge and tension of the film 90. On the contrary, if the tension of the film 90 in the upward direction of the vertical direction D _T is too small, the control unit 60 controls the first linear actuating unit 51 and the second linear actuating unit 52 to move downward simultaneously to provide Tension compensation.

As shown in Fig. 7C, in the third embodiment, the film 90 is in tension during the transfer, but is in an offset state. The state in which the edge and the tension are balanced is compared with FIG. 7A. In this state, the case where the film 90 is shifted is assumed as shown in FIG. 6B. The control unit 60 can control the first linear actuating unit 51 not to move such that the position of the oscillating wheel 10 is at the first origin position P ₁₀ . At the same time, the control unit 60 controls the second linear actuating unit 52 to move upward to provide offset compensation. More specifically, the control unit 60 controls the second linear actuation unit 52 to move upward from the second origin position P ₂₀ to a second movement position P _2U , and the difference between the two positions is defined as a second Compensation distance ΔP ₂ . In addition, if the film 90 is offset as shown in FIG. 6B, the control unit 60 can control the second linear actuating unit 52 not to move, so that the position of the swing wheel 10 is at the second origin position P. ₂₀ . At the same time, the control unit 60 controls the first linear actuating unit 51 to move downward to provide offset compensation.

On the contrary, if the film 90 is shifted, it is as shown in Fig. 6A. The control unit 60 controls the second linear actuator means 52 does not move, so that the position of the wheel 10 is swung in the second origin position P _20. At the same time, the control unit 60 controls the first linear actuating unit 51 to move upward to provide offset compensation. In addition, if the film 90 is offset as shown in FIG. 6A, the control unit 60 can control the first linear actuating unit 51 not to move, so that the position of the swing wheel 10 is at the first origin position. P ₁₀ . At the same time, the control unit 60 controls the second linear actuation unit 52 to move downward to provide offset compensation.

As shown in Fig. 7D, in the fourth embodiment, the film 90 is displaced during transport and the tension is out of balance. 7A is a state in which both the edge and the tension are balanced. In this state, it is assumed that the tension of the film 90 in the upward direction by the vertical direction D _T is excessive, and the film 90 is displaced as shown in FIG. 6B. The control unit 60 controls not only the first linear actuating unit 51 and the second linear actuating unit 52 to move upward to provide tension compensation, but the control unit 60 controls the second linear actuating unit 52 to move upward. The distance is greater than the distance that the second linear actuating unit 52 moves upward to simultaneously perform offset compensation.

More specifically, the control unit 60 controls the first linear actuating unit 51 to move upward from the first origin position P ₁₀ to a first moving position P _1U , and the difference between the two positions is defined as a first A compensation distance ΔP ₁ . At the same time, the control unit 60 controls the second linear actuation unit 52 to move upward from the second origin position P ₂₀ to a second movement position P _2U , and the difference between the two positions is defined as a second compensation distance ΔP. ₂ . Since the film 90 is displaced and the tension is out of balance in the embodiment, the first compensation distance ΔP _{1 is} different from the second compensation distance ΔP ₂ . Since the film 90 is displaced as shown in FIG. 6B, the second compensation distance ΔP _{2 is} greater than the first compensation distance ΔP ₁ . Wherein the first compensation distance ΔP ₁ provides compensation for the tension imbalance of the film 90, and the difference between the second compensation distance ΔP ₂ and the first compensation distance ΔP ₁ , that is, ΔP ₂ -ΔP ₁ , provides the film 90 offset compensation occurred.

With respect to the film 90 described above, the tension in the upward direction of the vertical direction D _T is excessively large, and the film 90 is offset. As shown in FIG. 6B, there is another possible state of imbalance, that is, the film. 90 is an excessive tension in the upward direction by the vertical direction D _T , and the film 90 is offset in an unbalanced state as shown in FIG. 6A, and the film 90 is too small in tension in the upward direction by the vertical direction D _T , and The case where the film 90 is shifted is an unbalanced state as shown in Figs. 6A and 6B, respectively. Therefore, for the three unbalanced states, the manner in which the first linear actuating unit 51 and the second linear actuating unit 52 are controlled can be analogized according to the description of the embodiment of FIG. 7B to FIG. 7D, and thus is no longer Describe the description.

It is worth mentioning that the three conditions of the above-mentioned FIG. 7B to FIG. 7D are performed for the edge compensation or/and the tension compensation mode and the compensation amount only at a certain time when the film 90 is in the edge offset or/and the tension is out of balance. The compensation, through the control unit 60, provides edge compensation or/and tension compensation of negative feedback, which can gradually converge the edge offset or/and the amplitude of the tension imbalance, and finally control the film 90 to operate unbiased. Move and tension balance.

As shown in FIG. 5, the control unit 60 receives the edge sensing value E _D and the first power sensing value F _S1 and the second power sensing value F _S2 to calculate and process the corresponding A linear actuating unit 51 and the second linear actuating unit 52 drive the oscillating wheel 10 to move along the vertical direction D _T to simultaneously perform edge and tension control on the film 90. More specifically, the control unit 60 performs edge compensation or/and tension compensation of the negative feedback based on the received edge sensing value E _D and the first force sensing value F _S1 and the second force. a sensed value F _S2 , a force control command value controlled by the first linear actuating unit 51 and the second linear actuating unit 52, that is, the first power control command value F _CM1 and the second power control command The value F _CM2 is adjusted to dynamically and instantaneously control the first linear actuating unit 51 and the second linear actuating unit 52 to control the film 90 to operate in an unshifted and tension balanced state.

Therefore, in the present creation, the control calculus relationship of the control unit 60 for the edge control and the tension control is as follows:

1. Edge control relationship: F _CM2 -F _CM1 =k×(E _D -E _D0 ). In the above relationship, F _CM1 and F _CM2 are the first power control command value and the second power control command value respectively; E _D and E _D0 are the edge sensing value and the edge reference value, respectively. Furthermore, the above relationship can be rewritten as: F _CM2 -F _CM1 =k×ΔE _D , that is, there is a difference between the difference between the two force control command values (F _CM2 -F _CM1 ) and the edge offset value ΔE _D The relationship of the constant multiple k. It can be known from the above relationship that when the film 90 is not offset, that is, ΔE _D =0, the first force control command value F _{CM1 is the} same as the second force control command value F _CM2 . On the other hand, if the film 90 is offset during transmission, that is, ΔE _D ≠0, the control unit 60 changes the first force control command value F _CM1 and / according to the positive and negative values and magnitude of the edge offset value ΔE _D . Or the second force control command value F _CM2 to dynamically and immediately control the first linear actuating unit 51 and the second linear actuating unit 52.

2. Tension control relationship: F _CM1 +F _CM2 =F _S1 +F _S2 +2ΔT. In the above relationship, F _CM1 and F _CM2 are the first power control command value and the second power control command value, respectively, and F _S1 and F _S2 are the first power sensing value and the second power sensing value, respectively. And 2ΔT is a tension change value, wherein 2ΔT is a tension change value of the film 90 wound in the upward direction of the vertical direction D _T across the sides of the swing wheel 10. It can be known from the above relationship that when the tension of the film 90 is balanced, that is, ΔT=0, the sum of the first force control command value F _CM1 and the second force control command value F _CM2 (F _CM1 +F _CM2 And is equal to the sum of the first force sensing value F _S1 and the second force sensing value F _S2 (F _S1 +F _S2 ). On the other hand, if the tension of the film 90 is unbalanced during transmission, that is, ΔT≠0, the control unit 60 changes the first force control command value F _CM1 and/or the first according to the positive and negative magnitude and magnitude of the tension change value ΔT. The second force control command value F _CM2 controls the first linear actuating unit 51 and the second linear actuating unit 52 dynamically and instantaneously. It is worth mentioning that the magnitude of the force on both sides of the axle 11 and the weight W of the oscillating wheel 10 (W=m×g, where m is the mass of the oscillating wheel 10, g is the gravitational acceleration) and the oscillating wheel 10 The force F (F = m × a, where m is the mass of the oscillating wheel 10 and a is the acceleration of the oscillating wheel 10) is related to the movement force F (F = m × a) in the vertical direction D _T .

The edge sensing unit 30 senses the position of the edge 91 of the film 90 to output the edge sensing value E _D , in combination with the first force sensing unit 41 and the second force sensing unit 42 . The magnitude of the force on both sides of the axle 11 is detected to output the first force sensing value F _S1 and the second force sensing value F _S2 . The control unit 60 receives the sensing values E _D , F _S1 , F _S2 , and can quickly calculate the first power control command value F through the simultaneous operation of the edge control relationship and the tension control relationship. _{The CM1} and the second force control command value F _CM2 further control the first linear actuating unit 51 and the second linear actuating unit 52. More specifically, according to the simultaneous operation of the edge control relationship and the tension control relationship, the first power control command value F _CM1 and the second power control command value F _CM2 may be respectively calculated:

F _CM1 = 1/2 [F _S1 + F _S2 + 2 ΔT - k × (E _{D -} E _D0 )].

F _CM2 = 1/2 [F _S1 + F _S2 + 2 ΔT + k × (E _{D -} E _D0 )].

Referring to FIG. 5, the control unit 60 receives the edge sensing values E _D , the first power sensing value F _{S1 ,} and the second power sensing value output by the sensing units 30 , 41 , 42 . F _S2 performs an operation to obtain the first force control command value F _CM1 and the second force control command value F _CM2 to control the first linear actuation unit 51 and the second linear actuation unit 52. Further, the power control command values F _CM1 , F _{CM2 are} further fed back to generate updated power control command values, thereby achieving immediate and dynamic control of the first linear actuating unit 51 and the second linear Unit 52.

Referring to FIGS. 8A-8C, the first link unit 71 and the second link unit 72 of the present invention have different implementations of the roll-to-roll transfer system with tension and edge control. Taking FIG. 8A as an example, a first connecting unit 711 and a second connecting unit 721 are a combination of a hinge and a link, and the first position is changed through the rotating shaft and the relative position of the connecting rod. The linear actuating unit 51 and the second linear actuating unit 52 do not interfere with each other, and the oscillating wheel 10 can be maintained at a central position of the two linear actuating units 51, 52.

As shown in FIG. 8B , a first connecting unit 712 and a second connecting unit 722 are a combination of two sliding rails and two sliding blocks, and the sliding wheel 10 is coupled by the sliders and the sliding rails are fixed to the sliding rails 10 . The linear actuator units 51, 52 are on. The first linear actuating unit 51 and the second linear actuating unit 52 are prevented from interfering with each other by the movement of the sliders, so that the swinging wheel 10 can be maintained at the two linear actuating units 51, 52. Central location.

For example, in FIG. 8C, a first connecting unit 713 and a second connecting unit 723 are respectively a rotating shaft and a horizontal sliding rail. When the heights of the first linear actuating unit 51 and the second linear actuating unit 52 are different from each other, since one side of the swinging wheel 10 is restrained by the rotating shaft, the center of the swinging wheel 10 is followed. change.

Please refer to FIG. 9, which is a flow chart of a method for controlling a roll-to-roll transmission system with tension and edge control. The roll-to-roll transfer system with tension and edge control provides for transporting a film along a transport direction and winding the film. The roll-to-roll transmission system with tension and edge control includes a swing wheel, two idlers, and two linear actuating units. The oscillating wheel has an axle that extends axially through the oscillating wheel. The two idlers are used to support the film and to change the orientation of the film. The two linear actuating units are respectively mounted on opposite sides of the axle of the swinging wheel. Each of the linear actuating units can be a linear motor to provide reciprocating motion in a linear direction.

The roll-to-roll transmission system with tension and edge control further comprises two connecting units for connecting the two linear actuating units and the swinging wheel, respectively, for driving the swinging wheel when driving the linear actuating units mobile.

The roll-to-roll transmission system with tension and edge control further comprises an edge sensing unit and two force sensing units. The edge sensing unit is adjacent to the idler disposed on the downstream side of the transmission direction to accurately sense the position of the edge of the film to output an edge sensing value. The two force sensing units are respectively disposed on opposite sides of the axle to detect the force on both sides of the axle. Each of the force sensing units may be a load meter, and respectively detects the force on both sides of the axle to output two force sensing values.

The roll-to-roll transmission system control method with tension and edge control includes the following steps. In step S10, two power control command values are obtained. When the roll-to-roll transfer system with tension and edge control is activated, the two force control command values are initialized by a control unit. Then, in step S20, the edge sensing unit is sensed by the edge sensing unit. Then, in step S30, the two force sensing units are used to sense and obtain the two force sensing values.

Step S40, the control unit calculates and updates the two power control command values according to the edge sensing value, the two force sensing values, and the two power control command values. Then, in step S50, according to the updated two power control command values, the two linear actuating units are respectively controlled to perform a belt action for one swing wheel movement on the film.
