As shown in FIG. 2, the dancer unit 11 includes a dancer roller 111 disposed between the guide roller 12 on the outfeed roller 66 side and the guide roller 16 on the nip roller unit 13 side, and a support shaft provided at the base end. A support arm 112 rotatably supports the dancer roller 111 using a support arm 114 as a fulcrum, and a drive cylinder 113 presses the support arm 112 to rotate it.

The support arm 112 rotates about the support shaft 114 by the driving force of the drive cylinder 113, so that the dancer roller 111 presses the web W with a predetermined pressing force. Thereby, the dancer unit 11 adjusts the winding tension Tw applied to the web W so as to be balanced with the pressing force of the dancer roller 111.

The guide roller 12 is a roller that is arranged upstream of the dancer unit 11 and guides the web W. Further, the guide roller 16 is a roller that is arranged downstream of the dancer unit 11 and guides the web W.

The control unit 21 realizes each function of the control unit 21 shown in FIG. 3 by loading various operating programs and data stored in the storage unit 22 and the ROM of the control unit 21 into the RAM and operating the CPU. let Thereby, the control section 21 operates as a calculation section 211, a tension control section 212, and a nip load control section 213.

The calculation unit 211 calculates winding conditions such as an initial winding tension Tw 0 which is the initial value of the winding tension _{Tw input by the operator, an initial nip load N 0 which} is the initial value of the nip load N, and a winding speed Uw. An appropriate winding tension Tw and nip load N are calculated based on the setting parameter Ps that defines the winding tension Tw and nip load N. Calculation of the winding tension Tw and the nip load N can be performed using a known method, for example, the method described in Patent Document 1 can be used. That is, by optimizing the winding tension Tw and the nip load N based on the objective function and the constraint function of the objective function stored in advance in the storage unit 22, the winding tension Tw and the nip load N are adjusted to the winding roll. It is calculated as a function of the radial coordinate of 31.

The take-up control section 25 includes a motor driver that controls the take-up drive device 15 , and controls the operation of the take-up drive device 15 based on the control signal received from the tension control section 212 . Thereby, the winding control unit 25 controls the rotation of the drive shaft 14 and adjusts the winding tension Tw of the web W.

The dancer control section 26 includes a driver that controls the drive cylinder 113 of the dancer unit 11, and changes the pressing force of the drive cylinder 113 based on a control signal received from the tension control section 212. Then, the winding drive device 15 is controlled so that the dancer roller 111 is always at a predetermined position, and the winding tension Tw of the web W is adjusted.

The nip roller control section 27 drives the drive cylinder 132 based on the control signal received from the nip load control section 213. This controls the pressing force of the nip roller 131 on the take-up roll 31, that is, the nip load N.

Next, the winding operation of the web winding device 1 will be described based on FIG. 4, taking as an example the web winding device 1 that winds up the web W sent out from the gravure printing device 60.

First, the operator inputs the setting parameter Ps from the input unit 24 (step S11). The setting parameters Ps include the initial winding tension Tw ₀ applied to the web W, the initial nip load N ₀ at which the nip roller 131 presses the winding roll 31, the winding speed Uw of the web W, and the material of the web W. These setting parameters Ps are not limited to those input by the operator at the time of initial setting, and may be set in advance. Further, the setting parameter Ps may be selected from setting parameters Ps that are set in advance for each material of the web W, for example.

In addition, in the initial settings, the elastic modulus of the web W, the environmental temperature T of the web winding device 1, the material of the core C that winds the web W, and the winding start portion of the web W are set as additional conditions Ac. It is good also as including the pasting pattern which shows how to paste the pasting tape Tp for fixing to. The elastic modulus of the web W is not limited to numerical input, but can be set by displaying a list of materials for the web W stored in advance in the storage unit 22 on the display unit 23 and selecting from the displayed material list. It may also be a thing.

After the setting parameter Ps is input, the calculation unit 211 calculates the winding tension Tw and the nip load N based on the objective function and constraint function read from the storage unit 22 and the input setting parameter Ps (step S12).

In addition, when the data set Ds, which is the past performance data used in the past, is stored in the storage unit 22 (YES in step S13), the control unit 21 sets a setting parameter that approximates the setting parameter Ps input in step S11. The data set Ds including Ps is read out as a reference data set Dsr (step S14). If the data set Ds is not stored in the storage unit 22 (NO in step S13), the control unit 21 moves to the next process (step S18) without reading the data.

As shown in FIG. 5, the data set Ds includes setting parameters Ps, additional conditions Ac such as the environmental temperature T and the material of the core C, and the winding result Rr. The winding result Rr is a parameter indicating whether or not the winding roll 31 that was wound under the conditions expressed by the setting parameter Ps and the additional condition Ac had a problem. Approximate evaluation of the setting parameter Ps is performed, for example, by selecting the one with the smallest value shown in the following equation.

(However, Tw ₀ is the input initial winding tension, Tw _n is the initial winding tension of the data set Ds _n stored in the storage unit, Uw ₀ is the input winding speed, and Uw _n is the data set Ds _n is the winding speed, _N0 is the input initial nip load, N _n is the initial nip load of the data set Ds _n )

The control unit 21 causes the display unit 23 to display the winding tension Tw and nip load N calculated in step S12, each parameter included in the reference data set Dsr read from the storage unit 22 in step S14, and the winding result Rr ( Step S15). The operator determines whether or not to adjust the setting parameter Ps with reference to the winding result Rr and other parameters displayed on the display unit 23 (step S16).

FIG. 6 is a display example of the display unit 23. As shown in FIG. 6, input setting parameters Ps, additional conditions Ac, etc. are displayed as setting conditions on the left side, and in parallel with these, each parameter of the reference data set Dsr is displayed as reference conditions (actual data). . Further, the winding tension Tw and the nip load N calculated in step S12 are displayed on the right side of the display section 23. On the right side of the display unit 23, the winding result Rr of the reference data set Dsr and an operation start button 241 for starting winding are also displayed.

For example, if the winding result Rr of the reference data set Dsr, that is, the winding result Rr under the conditions expressed by the setting parameter Ps that approximates the input setting parameter Ps and the additional condition Ac, is good, the setting parameter Ps The initial setting is completed without adjusting the value, and the winding operation is started (NO in step S16). On the other hand, if the winding result Rr is not good, the operator adjusts the setting parameter Ps (YES in step S16). In adjusting the setting parameter Ps, the operator adjusts, for example, the winding speed Uw and inputs it again (step S17).

Returning to step S12, the calculation unit 211 calculates the winding tension Tw and the nip load N based on the objective function, the constraint function, and the re-input setting parameter Ps. Further, the control unit 21 reads from the storage unit 22 a reference data set Dsr that includes setting parameters Ps that approximate the re-input setting parameters Ps.

The control unit 21 causes the display unit 23 to display the calculated winding tension Tw, the nip load N, each parameter included in the reference data set Dsr read from the storage unit 22, and the winding result Rr. The operator repeats the above-described adjustment of the setting parameter Ps with reference to the winding result Rr displayed on the display unit 23 and other parameters until the operator determines that the setting parameter Ps is appropriate.

When the initial setting of the setting parameters Ps is completed (NO in step S16), the operator presses the operation start button 241 shown in FIG. 6. Thereby, the web winding device 1 starts the winding operation, and winding of the web W is started (step S18).

As shown in FIG. 1, the web W is set on an unwinding device 51, and is sent out from the unwinding device 51 to a gravure printing device 60. The gravure printing device 60 prints on the web W using printing units 61 , 62 , and 63 , and feeds the web W to the web winding device 1 via an outfeed roller 66 .

As shown in FIG. 2, the web W fed into the web winding device 1 is sent to the nip roller unit 13 after the winding tension Tw is adjusted by passing through the dancer roller 111 of the dancer unit 11. More specifically, the tension control unit 212 controls the winding control unit 25 and the dancer control unit 26 so that the actual winding tension Tw matches the winding tension Tw calculated in step S12. . As a result, the pressing force of the dancer roller 111 and the rotational speed of the drive shaft 14 are adjusted, and the winding tension Tw of the web W is controlled to an appropriate value.

The web W sent out from the dancer unit 11 is wound around the core C while being pressed by the nip roller 131 to form the take-up roll 31. The core C is attached to the drive shaft 14 as described above. The core C is rotationally driven together with the drive shaft 14 by the winding drive device 15 to wind up the web W.

The nip roller 131 is pressed against the take-up roll 31 with the nip load N calculated in step S12. The nip load control unit 213 adjusts the nip load N by controlling the drive cylinder 132 and moving the nip roller 131 based on the calculated nip load N.

When the web W of a preset length is wound up, the control unit 21 stops the operation of the winding drive device 15. The operator inspects the winding roll 31 after winding, and confirms whether there are any wrinkles, deviations, or other defects in the web W that has been wound. Then, the operator inputs the winding result Rr indicating whether or not there is a problem with the winding roll 31 from the input unit 24. The winding result Rr may be simple information selected from options such as ○: Good, △: Fair, ×: Bad, etc., or detailed text data in which the content of the defect is specifically entered in text. It may be.

The control unit 21 stores the input winding result Rr in the storage unit 22 as a data set Ds together with the setting parameter Ps and additional condition Ac input in step S11 (step S19).

After completing the input of the winding result Rr, the operator removes the winding roll 31 from the web winding device 1 (step S20) and finishes winding the web W.

As explained above, in the web winding device 1 according to the present embodiment, the setting parameters Ps and the performance data of the winding result Rr representing the quality of the winding roll 31 wound based on the setting parameters Ps are processed. present to the person concerned. As a result, the operator can estimate the quality of the winding result Rr based on the setting parameter Ps input at the time of initial setting, so the operator can adjust the setting parameter Ps before starting the operation of the web winding device 1 and Good conditions can be set. Therefore, defects in the winding roll 31 can be reduced and winding quality can be improved.

In the web winding device 1 according to the present embodiment, the environmental temperature T, which is the additional condition Ac, is directly input by the operator, but the present invention is not limited to this. For example, the environmental temperature T may be automatically input from the output of a temperature sensor provided in the web winding device 1.

Further, in the present embodiment, parameters included in the reference data set Dsr are displayed on the display unit 23 as performance data, but the present invention is not limited to this. For example, the winding tension Tw and nip load N calculated based on the setting parameters Ps of the reference data set Dsr may be displayed together with the winding tension Tw and nip load N calculated in step S12. Thereby, the difference in the winding tension Tw and nip load N between the input conditions and the conditions of the reference data set Dsr can be confirmed, so more appropriate parameters can be set.

(Embodiment 2)
Next, a web winding system 80 including the web winding device 2 and the database 72 according to the second embodiment will be described. In this embodiment, as shown in FIG. 7, the web winding device 2 includes a camera 50 for detecting the pasting pattern of the pasting tape Tp for pasting the winding start portion of the web W onto the core C by image recognition. This differs from the web winding device 1 of the first embodiment in that the present invention is provided. Further, this embodiment differs from the first embodiment in that the web winding device 2 includes a communication unit 70 and is connected via a network to a database 72 that stores the data set Ds. The other configurations are the same as those of the first embodiment, so the same reference numerals are given.

A camera 50 provided in the web winding device 2 is attached near the drive shaft 14, as shown in FIG. More specifically, the camera 50 is arranged at a position where it can photograph the core C set on the drive shaft 14 of the web winding device 2, and has an angle of view that can photograph the entire width of the web W. There is.

As shown in FIG. 7, the communication unit 70 is a communication device connected to the control unit 21 of the web winding device 2, and transmits and receives data to and from a database 72 on the network. Thereby, the web winding device 2 is communicably connected to the database 72 on the network. The communication unit 70 may be a wired communication device or a wireless communication device, and the communication unit 70 according to this embodiment is a wireless communication device.

The database 72 is a data server connected to the web winding device 2 via a network, and includes a storage section 721. The storage unit 721 of the database 72 stores a data set Ds including setting parameters Ps and winding results Rr as performance data when the web W was wound in the past.

The winding operation of the web winding system 80 according to this embodiment will be described below based on FIG. 9.

As in the first embodiment, the operator inputs setting parameters Ps including the initial winding tension Tw ₀ , initial nip load N ₀ , winding speed Uw, etc. from the input unit 24 (step S31).

After the setting parameter Ps is input, the calculation unit 211 calculates the winding tension Tw and the nip load N based on the objective function and constraint function read from the storage unit 22 and the input setting parameter Ps ( Step S32).

Further, the control unit 21 transmits the input setting parameter Ps to the database 72 via the communication unit 70 (step S33).

If the data set Ds is stored in the storage unit 721 (YES in step S34), the database 72 includes setting parameters Ps that approximate the received setting parameters Ps from the data set Ds stored in the storage unit 721. The reference data set Dsr is read (step S35). If the data set Ds is not stored in the storage unit 721 (NO in step S34), the database 72 transmits information indicating that the data set Ds is not stored to the web winding device 2, and the web winding device Step 2 moves to the next process (step S40). The approximate evaluation method for the setting parameter Ps is the same as in the first embodiment.

The database 72 transmits the reference data set Dsr read in step S35 to the web winding device 2 via the network (step S36).

The control unit 21 causes the display unit 23 to display the winding result Rr, the winding tension Tw calculated in step S32, the nip load N, etc. included in the received reference data set Dsr (step S37). As in the first embodiment, the operator refers to the winding result Rr displayed on the display unit 23 and determines whether or not to adjust the setting parameter Ps (step S38).

Further, the control unit 21 photographs the core C with the camera 50 and recognizes the pasting pattern of the pasting tape Tp for fixing the end portion of the web W to the core C based on the photographed image data. . More specifically, as shown in FIG. 10, the control unit 21 recognizes the shape of the adhesive tape Tp attached to connect the web W and the core C based on the image data, and registers the shape in advance. Select the applicable pattern from the pasting patterns that have been created. Thereby, the control unit 21 recognizes the pasting pattern of the pasting tape Tp, and displays it on the display unit 23 as one of the additional conditions Ac.

Referring to the displayed winding result Rr and other parameters, if the operator does not adjust the setting parameters Ps and operates with the current setting parameters Ps (NO in step S38), the operator completes the initial settings and The winding operation of the winding device 2 is started. When adjusting the setting parameter Ps (YES in step S38), the setting parameter Ps is adjusted and re-inputted via the input unit 24 (step S39).

When the setting parameter Ps is reset, the process returns to step S32, and the calculation unit 211 calculates the winding tension Tw and the nip load N based on the objective function, the constraint function, and the re-input setting parameter Ps. Further, the control unit 21 transmits the setting parameter Ps from the communication unit 70 to the database 72 (step S33). The database 72 reads a reference data set Dsr including setting parameters Ps that approximate the corrected setting parameters Ps from the storage unit 721 and transmits it to the web winding device 2 . Thereafter, similarly to Embodiment 1, the operator repeats adjustment of the setting parameter Ps until the operator determines that the setting parameter Ps is appropriate.

When the initial setting of the setting parameter Ps is completed (NO in step S38), the operator presses the operation start button 241 of the input unit 24. As a result, the web winding device 2 starts operating, and winding of the web W is started.

The operation from when the web W is fed out from the unwinding device 51 to being wound onto the core C via the gravure printing device 60 is the same as in the first embodiment (step S40).

When the web W of a preset length is wound up, the control unit 21 stops the operation of the winding drive device 15. The operator inspects the winding roll 31 after winding, and confirms whether there are any wrinkles or other defects in the web W that has been wound. Then, the operator inputs the winding result Rr indicating whether or not there is a problem with the winding roll 31 from the input unit 24.

The control unit 21 transmits the input winding result Rr to the database 72 as a data set Ds together with the setting parameter Ps input in step S31 and additional conditions Ac including the pasting pattern. The database 72 stores the received data set Ds in the storage unit 721 (step S41).

After completing the input of the winding result Rr, the operator removes the winding roll 31 from the web winding device 2 (step S42) and ends the winding process.

As described above, in the web winding system 80 according to the present embodiment, the data set Ds including the setting parameters Ps and the winding results Rr is stored in the database 72 on the network. As a result, it is possible to connect the database 72 and the plurality of web winding devices 2 and accumulate information on the data set Ds including more setting parameters Ps and winding results Rr, resulting in higher reliability. The winding process can be performed based on high information and the winding quality can be improved.

In addition, by analyzing the tendency of the winding result Rr for each web winding device 2 based on the data set Ds stored in the database 72, it is possible to analyze the trend of occurrence of defects in each web winding device 2, This makes it possible to detect malfunctions in the collecting device 2 at an early stage.

Although the camera 50 according to the present embodiment image-recognizes only the pasting pattern of the pasting tape Tp, the present invention is not limited to this. For example, the control unit 21 may determine the material of the core C from the color of the core C in the image taken by the camera 50, and register it as the additional condition Ac. Thereby, the setting parameter Ps can be adjusted in consideration of characteristics such as the elastic modulus of the core C, so that more appropriate condition settings can be made and the winding quality can be improved.

Further, the control unit 21 may determine the diameter of the core C from the color of the core C in the image taken by the camera 50, and register the diameter as the additional condition Ac. Thereby, the setting parameter Ps can be adjusted in consideration of changes in the winding diameter, so that more appropriate condition settings can be made and the winding quality can be improved.
