Description

  The present invention relates to a woven fabric winding device used in a multiple width weaving loom for weaving two or more woven fabrics.

  Conventionally, as a purpose of increasing productivity and reducing weaving cost, there is one that simultaneously weaves two or more woven fabrics in a wide loom. In the technical field of looms, a loom that performs such weaving is usually referred to as a multi-width weaving loom (a two-width weaving loom in the case of two weaving fabrics (2 widths)).

  An example of the multi-width weaving loom as described above is disclosed in Patent Document 1. However, the loom specifically described in Patent Document 1 is a two-width weaving loom. A specific description will be given of a plurality of weft looms taking the example of a double weaving loom described in Patent Document 1. In such a double weaving loom, a woven fabric (hereinafter referred to as “product weaving fabric”) as a product is used. The warp string is set up with the number of warp yarns twice the number of warp yarns corresponding to However, the warp row is set in a state in which the warp interval (interval between two adjacent warps) in the center in the weaving width direction is slightly larger than the warp interval in other portions in the weaving width direction. Then, using such a warp row, a woven fabric corresponding to two widths of the product woven fabric (hereinafter referred to as “woven fabric”) is woven. Then, the woven fabric is divided into two product woven fabrics by cutting the weft constituting the woven fabric at the center in the weaving width direction. Then, the two product woven fabrics simultaneously woven in this manner are sent to the woven fabric winding device side, and each is wound on a winding roll in the woven fabric winding device.

JP 2001-329453 A

  Although not disclosed in Patent Document 1, in a conventional general multiple width weaving loom, a plurality of product woven fabrics woven as described above is a single winding roll in a woven fabric winding device. On the other hand, it is wound up while shifting its position in the weaving width direction.

  For this reason, the conventional multi-width weaving loom has a problem in that the product woven fabric on the side opposite to the weft insertion side in the weft inserting direction is wound with the winding of the product woven fabric. The reason is as follows.

  In a general loom in recent years, a winding roll in a woven fabric winding device is rotationally driven while a driving torque is adjusted according to the wound diameter of the wound product woven fabric, that is, the winding fabric. In the winding process, the winding roll is rotationally driven at each time point with a driving torque corresponding to the winding diameter of the winding cloth, and accordingly, the product woven cloth connected to the winding cloth corresponds to the driving torque. The tension (tensile tension) is applied to the wound cloth while being applied from the wound cloth. Therefore, the tension of the product woven fabric itself corresponds to the tensile force applied from the wound fabric. Incidentally, the relationship between the tension (tensile force) and the drive torque of the take-up roll is F = T / D, where T is the tension, T is the drive torque, and D is the winding diameter. In this case, since the tensile force generated according to the driving torque of the winding roll is constant over the woven width direction of the woven fabric, is the tension of the woven fabric itself constant over the woven width direction? It seems like.

  However, in a multi-width weaving loom that is a wide loom for weaving a woven fabric corresponding to a plurality of widths of a product woven fabric, even if the tensile force is constant over the weaving width direction, the weft in the weft insertion direction In some cases, the tension of the woven fabric itself is different between the product woven fabric on the insertion side and the product woven fabric on the anti-weft insertion side.

  The reason is considered that the tension of the weft woven into the woven fabric is different between the weft insertion side portion and the anti-weft insertion side portion. That is, when the loom is wide, the weft yarn in one weft insertion is naturally long. For this reason, the weft tension at the time of beating may be different between the weft insertion side and the counter weft insertion side (the anti-weft insertion side is lower). And because the wefts are woven in such a different tension state, the weft insertion side portion and the weft insertion side portion of the woven fabric become different in tension, and the weft insertion side after splitting The woven fabric itself has different tensions between the product woven fabric and the product woven fabric on the anti-weft side. Therefore, when the product woven fabric with different tension states is wound up with a single winding roll as in the past, the winding diameter and the winding hardness in the wound state for each product woven fabric will be different. As a result, curling will occur on any of the woven fabrics.

  In view of the problems in the conventional multi-width weaving loom as described above, the present invention provides a multi-width weaving loom that simultaneously weaves a plurality of woven fabrics as product woven fabrics. The purpose is to prevent the occurrence of soot.

  The present invention relates to a woven fabric take-up device in a multiple width weaving loom that weaves two or more woven fabrics. And this invention is the winding roll of the same number as the number of the said woven fabrics provided corresponding to each of the two or more said woven fabrics, Comprising: The direction of an axis line corresponds to the width direction of a loom on the winding side of a loom A plurality of winding rolls provided, a plurality of drive mechanisms provided in correspondence with the respective winding rolls, a rotary shaft that is rotationally driven by a driving device, and provided corresponding to each winding roll And a plurality of drive mechanisms having drive transmission portions for transmitting the rotation of the rotating shaft to the corresponding winding rolls, and each driving mechanism can independently adjust the driving torque of each winding roll for each winding roll. It is characterized by being.

  In addition, about arrangement | positioning of each said winding roll in this invention, it is not restricted to what each winding roll is provided coaxially that "the direction of an axis line is made to correspond with the width direction of a loom", but each winding roll Are provided by shifting the position in the vertical direction and the front-rear direction (the direction perpendicular to the width direction in the horizontal direction). In other words, the arrangement of the winding rolls is not limited on the winding side of the loom as long as the direction of the axis is provided so as to coincide with the width direction of the loom.

  In the present invention, each of the drive mechanisms may include a drive motor as the drive device. In addition, the woven fabric winding device according to the present invention has a winding diameter of at least one winding roll in addition to the plurality of winding rolls and the driving mechanism provided corresponding to each winding roll. A winding diameter sensor to detect and a drive control device for the drive motor in each drive mechanism; and further, the drive control device according to the winding diameter so as to independently control the torque of each drive motor. The set value of the control parameter regarding the set drive torque of the drive motor may include a setter that is set individually for each drive motor. However, the “control parameter relating to the drive torque” mentioned here is not limited to the drive torque of the drive motor itself, but the corresponding parameter, for example, the tension applied to the woven fabric by the rotation of the winding roll driven by the drive motor. (Tensile force) is also included.

  According to the present invention, in a multi-width weaving loom, a plurality of woven fabrics are wound up by independent winding rolls, and the driving torque of each winding roll is set to the tension state of the woven fabric itself due to the weaving. Since it can adjust to what was considered, generation | occurrence | production of the winding habit of each woven fabric at the time of winding can be prevented.

  As shown in FIG. 1, in this embodiment, the loom 1 to which the woven fabric winding device 11 of the present invention is applied is a two-width weaving loom. Therefore, the warp row 2a sent out from the warp sending device (not shown) has twice as many warps 2 as the number of warps required to weave the product woven fabric 7b. Since the warp sending device has a large number of warp yarns as described above, for example, a device that feeds warp yarns simultaneously from a plurality of (for example, two) warp beams or the same number of yarn feeders as the number of warp yarns is set.

The rolls 8, 9, 9 are wound around a pair of press rolls 9, 9. Then, when the clothing roll 8 is driven by a winding motor (not shown), the woven fabric 7a is fed toward the woven fabric winding device 11 side.

  In the present embodiment, the woven fabric winding device 11 is a separate winding device that exists independently of the main body portion (weaving portion) of the loom 1. Therefore, the main body portion of the loom 1 is provided with a first guide roll 10 a for turning the woven fabric path toward the woven fabric winding device 11 side below the clothing roll 8. Further, the woven / woven fabric 7a is located at the center of the woven / woven fabric 7a in the width direction of the loom 1 (the warp described above) on the downstream side (for example, between the downstream press roll 9 and the first guide roll 10a). The product is cut into two product woven fabrics 7b and 7b by a cutting device (not shown) provided at a position where the interval between the warps 2 in the row 2a is increased. In the present application, the “width direction of the loom” is a direction that coincides with the weft insertion direction and is orthogonal to the warp direction, and is also simply referred to as “width direction” hereinafter. Each divided product woven fabric 7b is wound around the first guide roll 10a, turned to the woven fabric winding device 11 side, and sent to the woven fabric winding device 11.

It is supported by the beam member 14 via a support stay 22x.

  As shown in FIGS. 5 and 6, the drive control device 31 for controlling the drive of each of the drive motors M1 and M2 is provided in common to all the drive motors M1 and M2 in this embodiment. . In other words, the woven fabric winding device 11 of this embodiment includes a single drive control device 31 that is common to the two drive motors M1 and M2. And control of each drive motor M1 and M2 shall be controlled by the common drive control apparatus 31. FIG. The drive control device 31 includes a cloth winding drive controller 32 and a storage device 33 as a setting device. The cloth winding drive controller 32 and the storage device 33 are connected to each other to exchange signals.

  The cloth winding drive controller 32 is connected at its input end to a loom control device 35 which is a main control device of the loom 1. The loom control device 35 is connected to an encoder EN that detects the rotation of the main shaft 34 of the loom 1, and the loom control device 35 detects the rotation speed of the main shaft 34 based on a signal from the encoder EN. . The loom control device 35 outputs a rotation speed signal r indicating the detected rotation speed of the main shaft 34 to the cloth winding drive controller 32. The cloth winding drive controller 32 is connected at its input end to each of the winding diameter sensors 21s and 22s described above, and winding diameter signals d1 and d2 corresponding to the winding diameter of the winding cloth wound around each winding roll. Are input from the winding diameter sensors 21s and 22s.

  The cloth winding drive controller 32 detects the winding diameter of the winding cloth wound around the winding rolls 21 and 22 based on the winding diameter signals d1 and d2. Further, the cloth winding drive controller 32 is connected to an input setting unit 36 (described later) at its output end, and is connected to drivers 29a and 29b for driving the drive motors M1 and M2 at other output ends. Yes. However, the drivers 29a and 29b are provided corresponding to the respective drive motors M1 and M2, and the cloth winding drive controller 32 corresponds to the drivers 29a and 29b with respect to the respective drivers 29a and 29b. The drive command signals t1 and t2 for driving the drive motors M1 and M2 are output independently.

  The storage device 33 is connected to the cloth winding drive controller 32 as described above, and is connected to the input setting device 36 at its input end. In this embodiment, the input setting device 36 is provided with a touch panel display screen (setting screen 36a), and the setting screen 36a is used to perform input settings such as setting values and to set the setting values. It also serves as a display for setting values. The input setting unit 36 sets various settings of the loom 1, control parameters related to driving torque for controlling the driving motors M1 and M2 in the woven fabric winding device 11, and the like.

  FIG. 6 shows an example of a setting screen 36a in the input setting unit 36 for inputting and setting control parameters related to the drive torque of the drive motors M1 and M2 (hereinafter also simply referred to as “control parameters”). In the illustrated example, the notation <drive motor 1> corresponds to the drive motor M1 for driving the first take-up roll 21, and the notation <drive motor 2> indicates the second take-up roll 22. This corresponds to the drive motor M2 for driving. In this setting screen 36a, for each of the drive motors M1 and M2, the winding diameter at the beginning of winding (≈ winding roll diameter) starts from 85 mm, and a predetermined winding diameter (eg, 105 mm, 125 mm, 250 mm). ) Control parameters can be input and set every time.

  In the illustrated example, the control parameter is set as a tension (cloth tension (unit: N)) applied to the product woven fabric 7b. However, the cloth tension referred to here corresponds to a tensile force that the wound cloth exerts on the product woven cloth 7b when the woven cloth 7b is wound on the cloth wound around the winding roll. Incidentally, the relationship between the cloth tension and the driving torque of each of the drive motors M1 and M2 is F = T / D, where F is the cloth tension, T is the driving torque, and D is the winding diameter. However, the control parameter to be input and set is not limited to the cloth tension as illustrated, and may be the drive torque of each of the drive motors M1 and M2.

  When the control parameters for the respective winding diameters of the drive motors M 1 and M 2 are set in the input setting unit 36, the set values are output to the storage unit 33. Then, the storage device 33 uses the set values of the control parameters for the respective winding diameters of the drive motors M1 and M2 (hereinafter also simply referred to as “set values” (the set values)) as the drive motors M1 and M2. For each M2, the data is stored in association with the winding diameter.

  The cloth winding drive controller 32 in the drive control device 31 is based on the winding diameter signals d1 and d2 from the winding diameter sensors 21s and 22s and the set values of the control parameters set in the storage unit 33 during the operation of the loom 1. Drive command signals t1, t2 corresponding to the winding diameter are output to the drivers 29a, 29b of the drive motors M1, M2. Specifically, the cloth winding drive controller 32 determines the winding diameter of the winding cloth wound around each winding roll based on signals from the winding diameter sensors 21 s and 22 s in a predetermined cycle during the operation of the loom 1. Detect individually. Note that at the start of operation of the loom 1 (winding start time), the winding diameter is an initial value (85 mm in the illustrated example).

  Then, the cloth winding drive controller 32 determines the rotation speed of the main shaft 34 based on the detected winding diameter, the set value set in the storage device 33, and the rotation speed of the main shaft 34 based on the rotation speed signal r from the loom control device 35. Drive command signals t1 and t2 for driving the drive motors M1 and M2 so that the winding rolls 21 and 22 are driven at a rotational speed corresponding to the rotational speed and a drive torque corresponding to the set value, Output to the drivers 29a and 29b of the drive motors M1 and M2, respectively. However, the drive command signal t1 output to the driver 29a of the drive motor M1 corresponding to the first winding roll 21 is input and set in the setting field of <Drive motor 1> in the setting screen 36a of FIG. The drive command signal t2 output to the driver 29b of the drive motor M2 corresponding to the second winding roll 22 is based on the set value, and <drive motor 2 on the setting screen 36a in FIG. It is based on the set value input and set in the> setting column.

  In the example of FIG. 6, a control parameter (cloth tension) is set for each preset winding diameter, but between the determined winding diameters (for example, between 85 mm and 105 mm). The cloth winding drive controller 32 obtains the control parameters by linear interpolation or the like, and drive command signals t1 and t2 based on the obtained control parameters are output. The drivers 29a and 29b drive the corresponding drive motors M1 and M2 according to the drive command signals t1 and t2. Thereby, each winding roll (each drive motor M1, M2) is rotationally driven at a rotational speed corresponding to the rotational speed of the main shaft 34 and at a drive torque corresponding to the set value.

  According to the woven fabric winding device 11 in the present embodiment as described above, the two product woven fabrics 7b and 7b manufactured by dividing the woven fabric fabric 7a woven in the main body portion of the loom 1 are as follows. It winds up independently by the winding rolls 21 and 22 provided corresponding to each. Moreover, the winding rolls 21 and 22 that wind up the corresponding woven or woven fabric 7a are rotationally driven independently of the other roll by dedicated drive motors M1 and M2 that are torque controlled. In addition, control parameters that are the basis of drive commands for the drive motors M1 and M2 are set independently for the drive motors M1 and M2. In other words, the driving torque of each winding roll (each driving motor M1, M2) 21, 22 can be set (adjusted) independently for each winding roll.

  Therefore, even if the tension state of each product woven fabric 7b becomes different as a result of weaving, the drive motors M1 and M2 that are the drive sources of the winding rolls 21 and 22 for winding the product woven fabric 7b are provided. By setting the control parameters relating to the driving torque for driving in consideration of the tension state accompanying the weaving of each product woven fabric 7b, the tension state of the product woven fabric 7b corresponding to each winding roll 21, 22 is considered. Since each product woven fabric 7b is wound on the wound fabric while being pulled with a tensile force corresponding to the tension state, the product woven fabric 7b may be wound on the winding. Is prevented.

  In addition, about this invention, it is not limited to the Example (the said Example) demonstrated above, It can implement also in the following modified embodiment.

  In the case where a dedicated drive motor is used as a drive device (drive source) for driving the take-up roll as in the above embodiment, and the drive motor is controlled based on the winding diameter of the winding cloth detected by the winding diameter sensor. In the embodiment, two winding diameter sensors 21 s and 22 s are provided so as to correspond to the winding rolls 21 and 22, and the winding diameter of each winding cloth wound around the winding rolls 21 and 22 is detected. However, the detection of the winding diameter is not necessarily performed for each winding cloth, and only one winding diameter sensor is used to detect only the winding diameter of the winding cloth wound on one winding roll, and based on the detected value. It is also possible to control the drive of both drive motors M1, M2. That is, by controlling the driving torque of each drive motor M1, M2 in accordance with the tension state of each product woven fabric 7b in order to prevent winding during winding, each product woven fabric 7b has the same tension. As a result, the winding diameter of the winding cloth wound around each of the winding rolls 21 and 22 becomes substantially the same, so that the winding diameter of one winding cloth is the same. Even if the drive of both drive motors M1 and M2 is controlled based on this, there is substantially no problem.

  Moreover, in the said Example, while arranging the drive mechanism 23 on the same side regarding the width direction with respect to each winding roll 21 and 22, the length dimension of the 1st winding roll 21 and the 2nd winding roll 22 is set. Differently, with respect to the first winding roll 21 for winding the product woven fabric 7b on the side farther than the drive mechanism 23 (on the other main side wall 13b side), the other end side is supported by the other main side wall 13b. For the second winding roll 22 that extends over a range including the existence range of the second winding roll 22 and winds up the product woven fabric 7b on the one main side wall 13a side, the other end side is The center in the longitudinal direction supported by the second intermediate wall 16 is provided so as to coincide with the center in the width direction of the product woven fabric 7b on the one main side wall 13a side. (1), deformation like (2) Possible it is.

  (1) A driving mechanism 23 for driving the first winding roll 21 is disposed on the other end side of the first winding roll 21 and is connected to the other end of the first winding roll 21. It may be a thing. In the case of this configuration, the first winding roll 21 does not need to extend to the one main side wall 13a on the one end side. For example, the one end side is formed by the second intermediate wall 16. It is good also as a structure supported. That is, the second intermediate wall 16 is disposed between the two product woven fabrics 7b and 7b with respect to the width direction and extends to the upper side of the first winding roll 21 with respect to the vertical direction. The roll 21 may be supported by the second intermediate wall 16 and the other main side wall 13b. However, in this configuration, in order to reduce the distance between the two product woven fabrics 7b and 7b, the second intermediate wall 16 is penetrated in correspondence with the positions of the first and second winding rolls 21 and 22. A hole is formed, and the first winding roll 21 has one end passing through the second intermediate wall 16 and being supported by the surface of the second intermediate wall 16 on the side of the one main side wall 13a. For the second winding roll 22, the other end side penetrates the second intermediate wall 16 and is supported by the surface of the second intermediate wall 16 on the other main side wall 13b side. preferable.

  (2) About the 2nd winding roll 22, like the 1st winding roll 21 of the said Example, the said other end side has a length dimension supported by the said other main side wall 13b. Also good. And when the 1st winding roll 21 is comprised like the said Example, it is unnecessary about the 2nd intermediate wall 16 by making the 2nd winding roll 22 into such a structure. Become. That is, the winding rolls 21 and 22 are supported by the first intermediate wall 15 and the other main side wall 13b. And when it is set as the structure by which each winding roll 21 and 22 is supported by the 1st intermediate wall 15 and the said other main side wall 13b, about arrangement | positioning with respect to the winding rolls 21 and 22 of each drive mechanism 23, Either one end or the other end may be used.

  In the above-described embodiment, each drive mechanism 23 includes the dedicated drive motors M1 and M2 provided in correspondence with the winding rolls 21 and 22, but instead of each drive mechanism 23, Alternatively, the take-up rolls 21 and 22 may be rotationally driven by a single drive motor provided separately and common to all the drive mechanisms 23. That is, in the woven fabric winding device according to the present invention, each driving mechanism 23 is not limited to the one provided with the driving device (driving motor) as in the above-described embodiment, and what is each driving mechanism 23 or woven fabric winding device 11? A drive device provided separately may be used as a drive source. However, in such a configuration, when each drive mechanism 23 transmits the rotational torque of the output shaft of the drive motor to the corresponding take-up roll, the drive torque for the take-up roll is different from the other drive mechanism 23. The configuration must be independently adjustable. An example of such a drive mechanism 23 is a cloth winding torque adjusting device 23a as shown in FIGS. However, the example shown in FIGS. 7 and 8 is an example in which the drive mechanism 23 of the woven fabric winding device 11 in the above embodiment is changed to a fabric winding torque adjusting device 23a. Incidentally, FIG. 8B is a plan view of the entire cloth winding torque adjusting device 23a while including the DD cross-sectional view of FIG. 8A.

  The cloth winding torque adjusting device 23a is provided on each of the first and second winding rolls 21 and 22, as shown in FIG. Each cloth winding torque adjusting device 23a includes a first support shaft 59 that is rotatably supported with respect to the main body frame 12, and a winding roll having one end fixed to the first support shaft 59 and the other end corresponding thereto.

It is configured to abut against the wound fabric wound around the winding roll corresponding to 67.

  Accordingly, when the winding diameter of the winding cloth of each of the winding rolls 21 and 22 changes (increases), the position of the roller 67a that contacts the winding cloth is displaced, and the winding diameter tracking lever 67 is moved along the displacement by the first support shaft. The first support shaft 59 is also rotated along with the rotation. Thus, each cloth winding torque adjusting device 23 a is supported by the first support shaft 59, the winding diameter tracking lever 67 fixed at one end to the first support shaft 59, and the other end of the winding diameter tracking lever 67. The roller 67a includes a portion that follows the change amount of the winding diameter of the corresponding winding rolls 21 and 22.

The rotating plate 47 is not fixed to the support pins 46 and can be displaced in the direction of the rotation axis of the disk case 44. Further, the rotating plate 47 has a through hole 47h having a diameter larger than the shaft diameter of the connecting shaft 41 at the center thereof, and the connecting shaft 41 is inserted into the through hole 47h.

  In addition, the friction transmission unit 45 includes a plurality of discs (two in the illustrated example) provided between the adjacent rotary plates 47 and 47 and between the rotary plate 47 and the inner surface of the connecting portion 44a of the disc case 44. And a plurality of disk-shaped friction plates 49 provided between the driven plate 48 and the inner surface of the coupling portion 44a of the disk case 44. Each driven plate 48 has a connecting shaft 41 fitted in the center thereof, and is attached to the connecting shaft 41 so as to be displaceable in the axial direction and not to be relatively rotatable. However, each follower plate 48 has a smaller diameter than the rotary plate 47, and a pair of support pins 46, 46 are located apart from the outer peripheral edge thereof.

Accordingly, the pressing force setting unit 64 applies an urging force (pressing force) by the compression spring 65 to the friction transmission unit 45 via the pressing plate 52. Further, the compression spring 65 is adjusted by changing the screwing amount of the adjustment nut 66 relative to the male screw portion 41a of the connecting shaft 41 and adjusting the distance between the pressing plate 52 and the adjustment nut 66 (compression amount of the compression spring 65). The pressing force with respect to the friction transmission portion 45 by the urging force is changed.

Furthermore, the longitudinal dimensions of the support lever 58 and the contact lever 62 are set so that the roller 62c contacts the pressure lever 54 in a state where the support lever 58 is supported by the first support shaft 59. ing. Therefore, the driven lever 57 can be brought into contact with the contact surface 54a of the pressure lever 54 by the roller 62c, and the other main side wall 13b side by the biasing force setting portion 71 is provided on the other end side of the contact lever 62. As a result, the contact lever 62 rotates about the third support shaft 63, and the roller 62 c is pressed against the contact surface 54 a of the pressure lever 54. .

  The urging force setting portion 71 is provided so as to protrude outward with respect to the support lever 58, and has a guide shaft 72 that penetrates the contact lever 62, and a male screw portion 72 a formed at the outer end portion of the guide shaft 72. And an adjustment nut 73 that is screwed to the guide shaft 72 and a compression spring 74 that is inserted concentrically with the guide shaft 72 and interposed between the contact lever 62 and the adjustment nut 73. The guide shaft 72 is provided so as to pass through a through hole (not shown) formed on the other end side of the contact lever 62, but the diameter of the through hole (in the longitudinal direction of the contact lever 62). The diameter) is formed to be larger than the shaft diameter of the guide shaft 72, and the rotation of the contact lever 62 around the third support shaft 63 is not restricted by the guide shaft 72. According to the urging force setting portion 71 having such a configuration, the urging force described above is applied to the other end side of the contact lever 62 by the compression spring 74 and the adjusting nut 73 for the male screw portion 72a of the guide shaft 72 is applied. By changing the screwing amount and adjusting the distance between the contact lever 62 and the adjustment nut 73 (the compression amount of the compression spring 74), the urging force of the compression spring 74 against the contact lever 62 is changed.

  According to the pressing force adjusting unit 53 configured as described above, the driven lever 57 acts the urging force of the compression spring 74 on the contact surface 54a of the pressure lever 54 via the roller 62c. 54 receives a pressing force toward the outer side on the side opposite to the friction transmission portion with respect to the rotation center (second support shaft 55). As a result, the pressing lever 54 is pressed by the pressing roller 52 by the pressing roller 56. Thus, a pressing force is applied to the friction transmission part 45 via the. Therefore, in the friction transmission means 43, the friction transmission unit 45 receives a pressing force from each of the pressing force setting unit 64 and the pressing force adjustment unit 53 via the pressing plate 52 included in the pressing force generation unit 51. It has become.

  Further, in the pressing force adjusting unit 53, the winding diameter tracking lever 67 rotates with the change in the winding diameter of the first winding roll 21, and the first support shaft 59 and the same amount as the rotation amount are rotated. The driven lever 57 rotates, and the contact position of the roller 62c of the driven lever 57 with respect to the contact surface 54a of the pressure lever 54 changes. In other words, the driven lever 57 on the contact surface 54a of the pressure lever 54 changes. By changing the position where the pressing force acts, the pressing force that the pressure lever 54 acts on the friction transmission unit 45 via the pressure roller 56 changes. That is, since the distance from the rotation center (fulcrum) of the pressure lever 54 to the position (action point) of the pressure roller 56 is constant, the pressing force on the contact surface 54a of the pressure lever 54 as described above. As a result, the pressing force applied by the pressure roller 56 to the friction transmission unit 45 is increased by the lever principle. For example, at the position S and the position E shown in FIG. 8A, when the roller 62 c comes into contact with the pressure lever 54 at the position E than when the roller 62 c comes into contact with the pressure lever 54 at the position S. However, the pressing force that the pressure roller 56 acts on the friction transmission unit 45 increases. That is, as the contact position of the roller 62c of the driven lever 57 with respect to the contact surface 54a of the pressure lever 54 is separated from the rotation center of the pressure lever 54, the pressure roller 56 transmits the friction in proportion to the distance. The pressing force applied to the portion 45 is increased.

  As described above, when the pressing force applied to the friction transmission unit 45 by the pressing force generating unit (pressing force adjusting unit 53) 51 changes, the first winding roll 21 is proportional to the change in the pressing force. The rotational torque (drive torque of the take-up roll) applied to is changed. Further, the change in the contact position of the roller 62c of the driven lever 57 with respect to the contact surface 54a of the pressure lever 54 as described above is caused by the driven lever 57 (support lever 58) about the axis of the first support shaft 59. The rotation of the follower lever 57 is caused by the rotation of the first support shaft 59.

  With the configuration as the drive mechanism (cloth winding torque adjusting device 23a) described above, the rotation of the drive motor drives the shaft portion 42b of the sprocket 42 to rotate. Therefore, the shaft portion 42b of the sprocket 42 corresponds to the “rotary shaft” in the present invention. Further, the rotation of the shaft portion 42 b of the sprocket 42 serving as the rotation shaft is transmitted to the first winding roll 21 via the disk case 44, the friction transmission portion 45, and the connecting shaft 41, so The rotational torque (drive torque) of the first take-up roll 21 is changed by the pressing force applied to 45. Therefore, the combination of the disk case 44, the friction transmission part 45, the pressing plate 52, and the connecting shaft 41 corresponds to the “drive transmission part” in the present invention.

  Then, in the cloth winding torque adjusting device 23a as shown in the figure, the phase of the driven lever 57 with respect to the first support shaft 59 at the start of winding (position S of the driven lever 57 in FIG. 8A) is changed, or the driven lever The driving torque of the first winding roll 21 can be adjusted by adjusting the urging force by the urging force setting unit 71 in 57 and changing the pressing force applied to the pressure lever 54 by the roller 62c.

  In addition, in the examples shown in FIGS. 7 and 8, drive mechanisms (cloth winding torque adjusting devices 23 a) 23 as illustrated are provided corresponding to the respective winding rolls 21 and 22. Moreover, it can be said that it is the structure which can adjust the drive torque of each winding roll 21 and 22 independently for every winding roll.

  Moreover, in the said Example, although the 1st, 2nd winding rolls 21 and 22 shall be arrange | positioned by making height position differ regarding the up-down direction at the same position regarding the front-back direction, each winding roll However, the arrangement of the winding rolls 21 and 22 is not limited to this, and the positions are different in the front-rear direction. It is good also as what is arranged. In addition, when making the position of each winding roll 21 and 22 different in the front-back direction, the position of an up-down direction may differ as in the said Example, and may be the same. Moreover, as described in (1) of the above-described modification, one end side of the first winding roll 21 and the other end side of the second winding roll 22 are between two product woven fabrics 7b and 7b in the width direction. In the case of the configuration supported by the second intermediate wall 16 disposed in the first and second winding rolls 21 and 22, the first and second winding rolls 21 and 22 are disposed so that the positions of the axes coincide with each other when viewed in the width direction. It is also possible.

  In the above-described embodiment, the example in which the present invention is applied to the two-width weaving loom in which the two product woven fabrics 7b and 7b are simultaneously woven has been described. Not limited to this, a multi-width weaving loom that simultaneously weaves three or more product woven fabrics 7b may be used. In the above embodiment, the woven fabric winding device 11 is a separate winding device that is independent from the main body portion of the loom 1 that performs weaving. However, the woven fabric winding device according to the present invention includes such a separate winding device. As long as a plurality of winding rolls can be arranged together with the drive mechanism 23 on the winding side of the main body portion of the loom 1, the main body portion of the loom 1 that performs weaving corresponds to the woven fabric winding device of the present invention. It is good also as what has the structure to do. Further, when the main body portion of the loom 1 has the woven fabric winding device of the present invention, the main shaft (primary motor) 34 of the loom 1 is used as a drive source for the modified examples shown in FIGS. There may be.

  In addition, this invention is not limited to the said Example, In the range which does not deviate from the meaning, it can change suitably.
