Description

Technical Field

[0001] The present invention relates to a spinning take-up device that takes up the yarn spun from a spinning machine to form a winding package, and more particularly to a spinning take-up device for industrial material yarns that have a large fineness and require a long heating length.

Background Art

[0002] In a spinning take-up device that takes up the yarn spun from a spinning machine to form a winding package, at the start of production, a yarn hanging operation is required to hang the yarn spun from the spinning machine along the yarn path to the take-up section.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in recent years, there has been a demand for labor-saving in facilities. However, when performing the threading operation in a general spinning take-up device described in Patent Document 1, at least two operators are required, namely, a second-floor operator who threads the yarns onto each roller and a threading operator who threads the yarns onto the winding section. Also, when threading the yarns by two operators, namely, a second-floor operator who threads the yarns onto each roller and a threading operator who threads the yarns onto the winding section, it is necessary to transfer the suction gun that is sucking the yarns when threading the yarns onto each roller or the winding section, which increases the threading operation time. Even if the threading of the yarns onto each roller or the winding section is performed by one operator, since the threading operation on the second floor where each roller is arranged is a high-place operation, it is necessary to get on and off the work cart, which not only lengthens the time required for threading but also increases the burden on the operator. Therefore, suppressing the height of the spinning take-up device to make it low-floor and shortening the threading time and achieving labor-saving are urgent issues.

[0006] The present invention has been made in view of the above problems, and an object thereof is to make the spinning take-up device lower-floor than before and to shorten the threading time and achieve labor-saving.

Means for Solving the Problems

[0007] (1) The spinning take-up device of the present invention is a spinning take-up device that takes up a plurality of yarns spun from a spinning machine and at least stretches them, a plurality of yarn suction parts capable of sucking the plurality of yarns respectively, and a winding part that winds up the plurality of yarns sent from the spinning take-up part to form a winding package, and the spinning take-up part is provided below the plurality of yarn suction parts, and includes a first guide part provided with a direction-changing roller for changing the traveling direction of the plurality of yarns for each of the plurality of yarns, a stretching part including a plurality of rollers including at least one roller for stretching the plurality of yarns guided from the first guide part, and a second guide part for guiding the plurality of yarns from the stretching part to the winding part, and the winding part and the stretching part On the same floor, the axial direction of the winding unit is parallel to the running of the yarn in the extending unit in plan viewHorizontally arranged, and the first guide part is arranged above at least one roller of the extension part. A first yarn feeding roller is provided on the yarn path from the plurality of direction-changing rollers to the extension part. The first yarn feeding roller is provided at a position lower than the yarn suction part and at a position deviated horizontally from the first guide part and the extension part. It is characterized by this. Preferably, the first yarn feeding roller is provided at a position deviated from the winding unit in a direction opposite to the horizontal direction with respect to at least the extending unit Also preferably, the first yarn feeding roller is provided at a position deviated from the winding unit in a direction opposite to the horizontal direction with respect to both the first guiding unit and the extending unit

[0008] According to the spinning take-up device described in (1) above, the winding part and the extension part are On the same floor, the axial direction of the winding unit is parallel to the running of the yarn in the extending unit in plan view Horizontally arranged, and further, the first yarn feeding roller is 「 At a position lower than the yarn suction part and at a position deviated horizontally from the first guide part and the extension part. ", "a position deviated from the winding unit in a direction opposite to the horizontal direction with respect to at least the extending unit", or "a position deviated from the winding unit in a direction opposite to the horizontal direction with respect to both the first guiding unit and the extending unit" It is provided at. Therefore, the height of the first guide part arranged above at least one roller of the extension part can be reduced, and the height of the spinning take-up device can be suppressed and the floor can be lowered. As a result, it is not necessary to divide the working area on the first floor vertically as in the conventional case and arrange an operator in each working area, and it becomes possible to perform the yarn hanging work by one operator, so that the shortening of the yarn hanging work time can be achieved and labor saving can be achieved.

[0009] (2) In the spinning take-up device described in (1) above, In the first guide part, the plurality of direction-changing rollers provided for each of the plurality of yarns are arranged offset in a row in a direction orthogonal to the axial direction of the winding shaft of the winding part in a plan view. It is characterized by this.

[0010] According to the yarn take-off device described in (2) above, since a plurality of direction-changing rollers are arranged in a row shifted from each other in a direction orthogonal to the axial direction of the winding shaft in a plan view, it is possible to prevent the plurality of yarns sent from the plurality of direction-changing rollers from interfering with or getting entangled with each other. Also, in order to prevent the yarns from interfering with or getting entangled with each other, a guide for maintaining the yarn interval is not required. In particular, in order to arrange the first guide part at a lower position, it is preferable to reduce the distance between the first guide part and the extending part in the height direction. However, even if the distance between the first guide part and the extending part in the height direction is reduced, the effect is great in that it can prevent the plurality of yarns from interfering with or getting entangled with each other.

[0011] (3) In the yarn take-off device described in (2) above, for each of the plurality of yarns, the plurality of direction-changing rollers provided are arranged in a row shifted from each other at equal intervals in a direction orthogonal to the axial direction of the winding shaft of the winding part in a plan view. It is characterized by this.

[0012] According to the yarn take-off device described in (3) above, since a plurality of direction-changing rollers are arranged in a row shifted from each other at equal intervals in a direction orthogonal to the axial direction of the winding shaft in a plan view, it is possible to easily perform the operation of hanging the yarns on a guide (not shown) or an entangling device (not shown) for maintaining the yarn interval arranged on the downstream side in the yarn running direction from the plurality of direction-changing rollers.

[0013] (4) In the yarn take-off device according to any one of (1) to (3) above, the direction-changing roller is a roller that changes the running direction of the yarn spun downward from the spinning machine to a direction below the horizontal direction. It is characterized by this.

[0014] According to the yarn take-off device described in (4) above, the traveling direction of the yarn spun downward from the spinning machine is changed downward from the horizontal direction by the direction-changing roller. Therefore, even when the bending angle is the same as in the case of providing a conventional guide, tension can be applied to the yarn without applying a load to the yarn as much as possible. As a result, by using the direction-changing roller instead of the guide, the height can also be reduced. Further, by individually driving each of the plurality of direction-changing rollers, it is also possible to reduce the tension difference between the plurality of yarns.

[0015] (5) In the yarn take-off device according to any one of (1) to (4) above, the plurality of rollers include rollers arranged in two rows in the horizontal direction characterized in that.

[0016] According to the yarn take-off device described in (5) above, since the plurality of rollers include rollers arranged in two rows in the horizontal direction, the height of the plurality of rollers can be suppressed, and the stretching part can be made into a low floor.

[0017] (6) In the yarn take-off device according to any one of (1) to (5) above, the first yarn feed roller and the plurality of rollers are each arranged such that the winding angle of the yarn around each roller is less than 360 degrees, and the direction substantially orthogonal to the yarn path in plan view is the axial direction characterized in that.

[0018] According to the yarn take-off device described in (6) above, not only is the winding angle of the yarn around each of the first yarn feed roller and the plurality of rollers less than 360 degrees, but the direction substantially orthogonal to the yarn path in plan view is the axial direction. Therefore, the plurality of yarns travel while maintaining parallelism from the first guide part to at least the stretching part, and the traveling direction in plan view becomes only the X direction. Thus, the plurality of yarns can be made to travel so that the yarn paths from the first guide part to at least the stretching part do not shift in the axial direction of each roller.

[0019] (7) In the spinning take-up device according to any one of (1) to (6) above, the plurality of rollers, below the first guide part, The surface temperature is at least one preliminary heating roller arranged in two or three in the vertical direction and set to a first temperature, below the first guide part, The surface temperature is at least one stretching roller arranged in two or three in the vertical direction and set to a second temperature higher than the first temperature, below the first guide part, The surface temperature is at least one heat setting roller arranged in two or three in the vertical direction and set to a third temperature higher than the second temperature, and having this is characterized.

[0020] According to the spinning take-up device described in (7) above, by arranging at least one preliminary heating roller, at least one stretching roller, and at least one heat setting roller in two or three in the vertical direction below the first guide part, the stretching part can be made lower in height. Further, by making the stretching part lower in height, it is possible to prevent the work of threading the yarn to the plurality of rollers provided in the stretching part from becoming work at a high place.

[0021] (8) In the spinning take-up device according to (7) above, one or more first heat insulation boxes for accommodating the at least one preliminary heating roller, one or more second heat insulation boxes for accommodating the at least one stretching roller, one or more third heat insulation boxes for accommodating the at least one heat setting roller, further comprising the yarn outlet of the first heat insulation box adjacent to the second heat insulation box among the one or more first heat insulation boxes is separated from the yarn inlet of the second heat insulation box adjacent to the first heat insulation box among the one or more second heat insulation boxes, and the yarn outlet of the second heat insulation box is separated from the yarn inlet of the third heat insulation box this is characterized.

[0022] According to the spinning and winding device described in (8) above, it is provided with a plurality of heat-insulating boxes that accommodate a preliminary heating roller, a stretching roller, and a heat-setting roller respectively. Moreover, the yarn outlet-side opening of the Nth heat-insulating box is separated from the yarn inlet-side opening of the (N + 1)th heat-insulating box arranged downstream of the Nth heat-insulating box without being in communication. Therefore, heat transfer between the Nth heat-insulating box and the (N + 1)th heat-insulating box can be suppressed. Also, temperature setting management for each heat-insulating box can be easily carried out. Note that the number of the first heat-insulating boxes, the number of the second heat-insulating boxes, and the number of the third heat-insulating boxes are not limited to one. For example, a plurality of preliminary heating rollers can be separated and accommodated in a plurality of first heat-insulating boxes respectively. Similarly, a plurality of stretching rollers can be separated and accommodated in a plurality of second heat-insulating boxes respectively, or a plurality of heat-sets can be separated and accommodated in a plurality of third heat-insulating boxes respectively. to It can be easily carried out. Incidentally, the number of the first heat-insulating boxes, the number of the second heat-insulating boxes, and the number of the third heat-insulating boxes are not limited to one. For example, a plurality of preliminary heating rollers can be separated and accommodated in a plurality of first heat-insulating boxes respectively. Similarly, a plurality of stretching rollers can be separated and accommodated in a plurality of second heat-insulating boxes respectively, or a plurality of heat-sets can be separated and accommodated in a plurality of third heat-insulating boxes respectively.

[0023] (9) In the spinning and winding device described in (7) or (8) above, Among the at least one preliminary heating roller, the at least one stretching roller, and the at least one heat-setting roller, at least any one of the rollers is unitized, For the unitized rollers, a first unit in which a predetermined number of rollers are unitized and a second unit in which a number different from the predetermined number of rollers are unitized are prepared, and the first unit and the second unit are configured to be recombinable according to the application. It is characterized by this.

[0024] According to the spinning and winding device described in (9) above, by preparing a plurality of units with different numbers of rollers in advance, and recombining the units according to the stretching process, the yarn brand, etc., and setting them in the spinning and winding device, the recombination of the rollers according to the application can be facilitated.

[0025] (10) In the spinning and winding device described in any one of (1) to (9) above, A guide roller for guiding the yarn is arranged on the downstream side in the yarn running direction from the stretching part to the second guide part. The interior of the second guide part is arranged above the winding part directly so that the acute angle formed by the yarn running direction of the yarn fed from the guide roller and the horizontal plane is 0° or more and 20° or less. It is characterized by this.

[0026] According to the spinning take-up device described in (10) above, the height of the interior of the second guide part can be suppressed, and the yarn hanging operation on the interior of the second guide part can be prevented from becoming a high-place operation.

[0027] (11) In the spinning take-up device according to any one of (1) to (9) above, The stretching part more than On the downstream side in the yarn running direction guide to An inner roller is arranged, In the yarn running direction, between the interior of the second guide part and the propose Inner roller , guiding the yarn to the second guiding unit A second yarn feed roller is arranged, The interior of the second guide part is arranged above the winding part directly so that the acute angle formed by the yarn running direction of the yarn fed from the second yarn feed roller and the horizontal plane is 0° or more and 20° or less. It is characterized by this.

[0028] The spinning take-up device described in (11) above has an inner roller on the downstream side in the yarn running direction in the stretching part, and a second yarn feed roller is arranged between the interior of the second guide part and the guide roller in the yarn running direction, which is different from the spinning take-up device described in (9) above. Even in such a case, by arranging the interior of the second guide part so that the acute angle formed by the yarn running direction of the yarn fed from the second yarn feed roller and the horizontal plane is 0° or more and 20° or less, the height of the interior of the second guide part can be suppressed. As a result, the yarn hanging operation on the interior of the second guide part can be prevented from becoming a high-place operation. more than On the downstream side in the yarn running direction guide to An inner roller is arranged, and in the yarn running direction, a second yarn feed roller is arranged between the interior of the second guide part and the guide roller. In this regard, it is different from the spinning take-up device described in (9) above. Even in such a case, by arranging the interior of the second guide part so that the acute angle formed by the yarn running direction of the yarn fed from the second yarn feed roller and the horizontal plane is 0° or more and 20° or less, the height of the interior of the second guide part can be suppressed. As a result, the yarn hanging operation on the interior of the second guide part can be prevented from becoming a high-place operation.

[0029] (12) In the spinning take-up device according to any one of (1) to (11) above, The winding part includes two winding devices arranged side by side in a direction substantially orthogonal to the yarn path in a plan view, The spinning take-off unit distributes and sends the plurality of yarns to the two winding devices. At least the yarn suction part, the first guide part, the stretching part, the second guide part, and the first yarn feed roller are all arranged within the range in the width direction of the winding part. It is characterized by this.

[0030] According to the spinning take-off device described in (12) above, since the yarn suction part, the first guide part, the stretching part, the second guide part, the first yarn feed roller, and the second guide part are all arranged within the range in the width direction of the winding part, not only can the height of the spinning take-off device be reduced to make it a low-profile type, but also the expansion in the width direction can be suppressed, and the overall size can be made more compact.

[0033] Hereinafter, the spinning take-up device 1 according to the present invention will be described with reference to the drawings. The spinning take-up device 1 according to the present invention is a device for taking up a yarn for industrial materials of 300 denier or more, for example. FIG. 1 is an example of a perspective view showing an outline of the spinning take-up device 1. FIG. 2 is an example of a side view showing an outline of the spinning take-up device 1.

[0034] In the present embodiment, the X direction and the Y direction are defined as shown in FIGS. 1 and 2. Both the X direction and the Y direction are horizontal directions and are perpendicular to each other. The X direction is one direction indicated by an arrow in FIGS. 1 and 2. Therefore, when referring to "the direction opposite to the X direction" in this specification, it means the direction opposite to the arrow shown in FIGS. 1 and 2. On the other hand, the Y direction is two directions indicated by arrows in FIGS. 1 and 2.

[0035] [1. Overall Configuration of Spinning Take-up Device] The overall configuration of the spinning take-up device 1 will be described with reference to FIGS. 1 and 2. As shown in FIGS. 1 and 2, the spinning take-up device 1 mainly includes, in order from the upstream side in the yarn running direction, an oil supply unit 2, a yarn suction unit 4, a spinning take-up unit 6, and a winding unit 8.

[0036] The oil supply section 2 has a plurality of oil supply sections 2. These plurality of oil supply sections 2 are arranged in a line in the left - right direction on the plane of FIG. 2. Here, the reason for describing "in a line in the left - right direction on the plane of FIG. 2" instead of "in a line in the X direction" will be described later with reference to FIG. 4.

[0037] Although not shown in FIGS. 1 and 2, a spinning machine is arranged above the plurality of oil supply sections 2. The plurality of oil supply sections 2 apply an oil agent to the yarn 100 in the form of a bundle of filaments spun from the spinning machine. In the present embodiment, the spinning take - up device 1 includes the oil supply section 2, but it is not limited to this, and the spinning machine may be provided with the oil supply section 2.

[0038] The yarn suction section 4 has a plurality of yarn suction sections 4 and is generally called an aspirator. When the spinning take - up device 1 includes the oil supply section 2, these plurality of yarn suction sections 4 are respectively provided directly below the corresponding oil supply section 2, and temporarily suck and hold the yarn 100 when the yarn 100 is wound around each roller or when the yarn breaks. The yarn 100 coated with the oil agent by the oil supply section 2 travels downward through the front surface of the yarn suction section 4 and then travels toward the first guide section 10 described later. All of the plurality of yarn suction sections 4 are mainly configured to generate a suction force at the suction port by the flow of the compressed fluid.

[0039] The spinning take - up section 6 mainly includes, in order from the upstream side in the yarn traveling direction, a first guide section 10, a first yarn feed roller 20, a stretching section 28, a relaxation section 60, and a second guide section 70. Details of the first guide section 10, the first yarn feed roller 20, the stretching section 28, the relaxation section 60, and the second guide section 70 will be described later.

[0040] The winding unit 8 mainly includes a main frame 80, a first winding device 81, and a second winding device 91. The first winding device 81 and the second winding device 91 are arranged side by side in the Y direction. Since the first winding device 81 and the second winding device 91 have the same structure, hereinafter, the first winding device 81 will be described, and the description of the second winding device 91 will be omitted. In the present embodiment, the winding unit 8 includes two devices, namely the first winding device 81 and the second winding device 91, but it is not limited thereto, and it may be provided with one winding device.

[0041] The first winding device 81 mainly includes a disk-shaped turret 82 rotatably provided on the main frame 80, two winding shafts 84 cantilever-supported on the turret 82 with the X direction as the axial direction, and a plurality of shedding devices 85 for performing the shedding of the yarn 100.

[0042] A plurality of bobbins 86 are serially mounted on the winding shaft 84. The winding shaft 84 rotates by the drive of a motor (not shown), thereby rotating the plurality of bobbins 86 mounted on the winding shaft 84, and winding the yarn 100 around the rotating plurality of bobbins 86. The yarn 100 wound around the bobbin 86 forms a winding package. The case of viewing the winding unit 8 in the direction opposite to the X direction will be described later.

[0043] Here, the positional relationship between the stretching part 28 of the spinning take-up part 6 and the winding part 8 will be continuously described with reference to FIGS. 1 and 2. The stretching part 28 is located on the upstream side in the yarn running direction from the winding part 8 and is arranged on the side opposite to the X direction from the winding part 8. Specifically, the stretching part 28 and the winding part 8 are horizontally arranged on the same floor such that the axial direction of the winding shaft 84 and the running direction of the yarn 100 at the stretching part 28 in plan view are parallel. That is, in the present embodiment, different from the conventional spinning take-up device in which the working area on the first floor is divided vertically, the winding part is arranged in the lower working area on the first floor and the stretching part is arranged in the upper working area, the stretching part 28 is arranged at a height position almost the same as that of the winding part 8. By doing so, the stretching part 28 can be arranged to such an extent that one operator can perform the yarn threading work for the stretching part and the winding part without using a work cart or the like. As a result, the shortening of the yarn threading work time can be achieved, and labor saving can be achieved.

[0044] Note that the first guide part 10 is arranged near the upper part of the stretching part 28. Further, the yarn suction part 4 is arranged directly above the first guide part 10, and the oil supply part 2 is arranged directly above the yarn suction part 4. The operational effects achieved by arranging each member in the vicinity will be described later, including the positional relationship with the first yarn feed roller 20.

[0045] [2. Spinning take-up part] Hereinafter, the first guide part 10, the first yarn feed roller 20, the stretching part 28, the relaxation part 60, and the second guide part 70 provided in the spinning take-up part 6 will be described.

[0046] [2-1. First guide part, first yarn feed roller] FIG. 3 is an example of a side view showing the periphery of the first guiding part 10. As shown in FIG. 3, the first guiding part 10 is mainly composed of a plurality (for example, 12) of direction-changing rollers 10A to 10L. The plurality of direction-changing rollers 10A to 10L are arranged in a row in the left-right direction on the plane of FIG. 3. Specifically, the direction-changing rollers 10A to 10F are arranged from left to right on the plane of FIG. 3, and the direction-changing rollers 10G to 10L are arranged from right to left on the plane of FIG. 3. Here, the reason for describing "arranged in a row in the left-right direction on the plane of FIG. 3" instead of "arranged in a row in the X direction" will be described later with reference to FIG. 4 in conjunction with the plurality of oil supply parts 2 described as "arranged in a row in the left-right direction on the plane of FIG. 2".

[0047] In addition, in the present embodiment, although it has been described that the plurality of direction-changing rollers 10A to 10L are arranged in a row in the left-right direction on the plane of FIG. 3, the plurality of direction-changing rollers 10A to 10L may be arranged horizontally or may be arranged with a shift in the vertical direction.

[0048] The plurality of direction-changing rollers 10A to 10L are rollers for sending a plurality (for example, 12) of yarns 100 spun downward from a spinning machine and coated with an oil agent, for each of the plurality of yarns 100, to a first yarn feed roller 20 located below the horizontal direction. Note that "below the horizontal direction" is preferably slightly below the horizontal direction. For example, it is preferable that the acute angle formed by the yarn running direction of the yarn 100 sent from the direction-changing rollers 10A to 10L to the first yarn feed roller 20 and the horizontal plane is greater than 5 degrees and not more than 30 degrees. The "acute angle formed by the yarn running direction of the yarn 100 sent from the direction-changing rollers 10A to 10L to the first yarn feed roller 20 and the horizontal plane" corresponds to the angle α shown in FIG. 3.

[0049] The yarn 100 whose running direction is changed by the direction-changing rollers 10A to 10F is sent to a first winding device 81 (see FIG. 1) and wound. Also, the yarn 100 whose running direction is changed by the direction-changing rollers 10G to 10L is sent to a second winding device 91 (see FIG. 1) and wound.

[0050] The first yarn feeding roller 20 is a roller provided on the yarn path from the first guiding part 10 to the extending part 28, and is a roller having an axial direction in a direction substantially orthogonal to both the yarn traveling direction and the vertical direction (i.e., the Y direction). The first yarn feeding roller 20 is located between the first guiding part 10 (i.e., the plurality of direction-changing rollers 10A to 10L) and the extending part 28 in the vertical direction, and is arranged on the side opposite to the X direction with respect to both the first guiding part 10 (more specifically, the direction-changing roller 10G) and the extending part 28 in the horizontal direction. That is, the first guiding part 10 and the extending part 28 are vertically arranged at positions overlapping in plan view, while the first yarn feeding roller 20 is arranged at a position deviated horizontally from both the first guiding part 10 and the extending part 28 and does not overlap with either of them in plan view. However, from the perspective of space saving, it is preferable that the first yarn feeding roller 20 is in the vicinity of the first guiding part 10 and the extending part 28 in the horizontal direction.

[0051] In this way, by arranging the first guiding part 10 near the upper part of the extending part 28 and arranging the first yarn feeding roller 20 at a position deviated to the side opposite to the X direction with respect to both the first guiding part 10 and the extending part 28, the vertical distance between the first guiding part 10 and the extending part 28 can be reduced. Also, by reducing the vertical distance between the first guiding part 10 and the extending part 28, the heights of the first guiding part 10, the yarn suction part 4 arranged directly above the first guiding part 10, and the oil supply part 2 arranged directly above the yarn suction part 4 can also be suppressed, and the entire spinning take-up device 1 can be made to have a lower floor. As a result, it is not necessary to divide the working area on the first floor vertically as in the conventional case and arrange an operator in each working area, and it becomes possible to perform the yarn hanging operation by one operator, so that the yarn hanging operation time can be shortened and labor saving can be achieved.

[0052] The yarn 100 fed out from the first yarn feeding roller 20 travels toward the extending part 28. The winding angle of the yarn 100 around the first yarn feeding roller 20 is less than 360 degrees.

[0053] A plurality of yarns 100 spun downward from a spinning machine not only contact the respective roller surfaces of a plurality of direction-changing rollers 10A to 10L, but are wound at a winding angle of, for example, 45 degrees or more and less than 90 degrees. In particular, by installing the first yarn feed roller 20 on the side opposite to the X direction with respect to the direction-changing roller 10G and making the angle α as small as possible, it becomes possible to increase the winding angle of the yarn around each of the direction-changing rollers 10A to 10L, and the gripping force between the yarn 100 and each of the direction-changing rollers 10A to 10L increases. Therefore, tension can be applied to the yarn 100 between the plurality of direction-changing rollers 10A to 10L and the first yarn feed roller 20, and the running of the yarn 100 on the downstream side of the plurality of direction-changing rollers 10A to 10L can be stabilized. Furthermore, a guide for finely adjusting the tension on the yarn, as provided conventionally, becomes unnecessary, and accordingly, the oil supply unit 2 and the yarn suction unit 4 can be arranged at a lower position than a yarn take-up device provided with a guide. Moreover, since the running direction of the yarn 100 is changed by rollers, the burden on the yarn 100 can be reduced as much as possible. When the yarn separation position on the circumferential surface of the plurality of direction-changing rollers 10A to 10L is vertically lower than the yarn entry position on the circumferential surface of the first yarn feed roller 20, the winding angle in contact with each roller surface of the plurality of direction-changing rollers 10A to 10L exceeds 90 degrees.

[0054] The plurality of direction-changing rollers 10A to 10L are each provided with a plurality of motors (not shown) corresponding to each roller. When the first yarn feed roller 20 is arranged at a position deviated from either the first guide part 10 or the extension part 28 on the side opposite to the X direction, the distances from each of the direction-changing rollers 10A to 10L to the first yarn feed roller 20 (i.e., the yarn lengths) are different, and there is a possibility that the tensions are different for each of the plurality of yarns 100. Therefore, by enabling each of the plurality of direction-changing rollers 10A to 10L to be individually driven, the yarn feed speed becomes stable, and it becomes possible to suppress variations in yarn tension even when the yarn lengths are different.

[0055] Next, with reference to FIG. 4, the positional relationship among the plurality of oil supply units 2, the plurality of yarn suction units 4, and the plurality of direction change rollers 10A to 10L will be described. FIG. 4 is an example of a plan view showing the plurality of oil supply units 2, the plurality of yarn suction units 4, and the first yarn feed roller 20.

[0056] As shown in FIG. 4, in the oil supply unit 2, the plurality of oil supply units 2A to 2L are arranged in a row at equal intervals in the left - right direction and the Y - direction (i.e., the direction orthogonal to both the take - up shaft 84 (see FIG. 1) and the vertical direction) on the plane of FIG. 4. Although not shown in FIG. 4, the yarn suction units 4A to 4L (see FIG. 3) are arranged directly below each of the oil supply units 2A to 2L. Similar to the direction change rollers 10A to 10L, the oil supply units 2A to 2F are arranged from left to right on the plane of FIG. 4, and the oil supply units 2G to 2L are arranged from right to left on the plane of FIG. 4.

[0057] Also, although the first guide part 10 (the plurality of direction change rollers 10A to 10L) is not shown in FIG. 4, the direction change rollers 10A to 10L are arranged directly below each of the yarn suction units 4A to 4L. Therefore, the plurality of direction change rollers 10A to 10L are also arranged in a row at equal intervals in the Y - direction with a shift. By doing so, the plurality of yarns 100 spun from the spinning machine will travel while being shifted from each other in the Y - direction so as to be parallel in plan view, and it is possible to prevent the yarns from interfering with or entangling with each other. In particular, in this embodiment, although the vertical distance between the first guide part 10 and the stretching part 28 is made small, even in such a case, the plurality of yarns 100 can be made to travel in parallel, and it is possible to prevent the plurality of yarns from interfering with or entangling with each other. Also, it is possible to easily perform the operation of hanging the yarns on a guide (not shown) or an interlacing device (not shown) that maintains the yarn interval in the yarn path between the plurality of direction change rollers 10A to 10L and the distribution rollers 70A to 70L. However, this is not limited thereto. It is not necessary to provide a guide or an interlacing device that maintains the yarn interval between the plurality of direction change rollers 10A to 10L and the distribution rollers 70A to 70L.

[0058] The reason for describing the arrangement of the plurality of oil supply parts 2A to 2L and the plurality of yarn suction parts 4A to 4L as "displaced in the left-right direction and the Y direction on the plane of FIG. 4" instead of "displaced in the X direction and the Y direction" is that the X direction means one direction. That is, this is to avoid the possibility of inconsistency with the description of "displaced in the Y direction" when the description "arranged in the X direction" is interpreted restrictively as being arranged in series in one direction such as the X direction. In the description with reference to FIGS. 2 and 3, the reason for describing "arranged in a row in the left-right direction on the plane of FIG. 2" or "arranged in a row in the left-right direction on the plane of FIG. 3" instead of "arranged in a row in the X direction" is also for the same purpose. That is, this is to avoid being interpreted that there is no displacement in the Y direction when it is described as "arranged in a row in the X direction".

[0059] Incidentally, the numbers of the plurality of oil supply parts 2, the plurality of yarn suction parts 4, the plurality of direction change rollers 10A to 10L, the plurality of shedding devices 85, and the plurality of bobbins 86 are not particularly limited.

[0060] [2-2. Stretching part] FIG. 5 is an example of a side view showing the periphery of the stretching part 28. As shown in FIG. 5, the stretching part 28 mainly includes a plurality of preheating rollers 31 to 34 for heating the yarn 100 before stretching, a plurality of stretching rollers 41 to 44 arranged on the downstream side of the preheating rollers 31 to 34, and a plurality of heat setting rollers 51 to 56 arranged on the downstream side of the stretching rollers 41 to 44 for conditioning the stretched yarn 100.

[0061] By the way, conventionally, in order to secure the heating length, a plurality of turns of yarn were wound around a long roller with a relatively large roller width. However, in the spinning take-up device 1 of the present embodiment, a short roller with a roller width smaller than that of the conventional one is used, and the winding around the roller is less than one turn. However, in order to secure the heating length while making the winding around the roller less than one turn, a larger number of rollers than the conventional ones are required. In particular, for example, in a spinning take-up device for producing yarn for industrial materials of 300 denier or more, a longer heating length is required compared to a spinning take-up device for clothing yarn. Therefore, in the spinning take-up device 1 of the present embodiment, the preliminary heating rollers 31 to 34, the drawing rollers 41 to 44, and the heat setting rollers 51 to 56 are horizontally arranged in series in the X direction on the same floor, so that the winding around the roller is less than one turn (the winding angle around the roller is less than 360 degrees), and the drawing section 28 can be made lower. The preliminary heating rollers 31 to 34, the drawing rollers 41 to 44, and the heat setting rollers 51 to 56 correspond to the "plurality of rollers" of the present invention.

[0062] The yarn feeding speed of at least the most upstream drawing roller 41 among the drawing rollers 41 to 44 is greater than the yarn feeding speed of the most downstream preliminary heating roller 34 among the preliminary heating rollers 31 to 34. Therefore, the yarn 100 is drawn between the most downstream preliminary heating roller 34 among the preliminary heating rollers 31 to 34 and the most upstream drawing roller 41 among the drawing rollers 41 to 44.

[0063] The preliminary heating rollers 31 to 34, the drawing rollers 41 to 44, and the heat setting rollers 51 to 56 are each provided with a plurality of motors (not shown) corresponding to each roller so that each can be individually driven.

[0064] The preliminary heating rollers 31 to 34, the drawing rollers 41 to 44, and the heat setting rollers 51 to 56 all have the direction substantially orthogonal to the yarn path in plan view (that is, the Y direction) as the axial direction, and two rollers arranged close to each other in the vertical direction are horizontally arranged along the X direction. However, the number of rollers arranged in the vertical direction is not limited to two, and three rollers may be arranged in the vertical direction as long as the yarn hanging operation by one operator is possible.

[0065] The yarn 100 fed out from the first yarn feed roller 20 is first sent to the preliminary heating roller 31, and then runs in the order of the preliminary heating rollers 32 to 34, the drawing rollers 41 to 44, and the heat setting rollers 51 to 56. In the preliminary heating rollers 32 to 34, the drawing rollers 41 to 44, and the heat setting rollers 51 to 56, the yarn 100 runs in an S shape from below to above between two rollers arranged close to each other in the vertical direction, and then runs toward the lower roller among the upper and lower two rollers arranged on the downstream side.

[0066] The winding angle of the yarn 100 around each of the preliminary heating rollers 31 to 34, the drawing rollers 41 to 44, and the heat setting rollers 51 to 56 is less than 360 degrees for each roller.

[0067] The surface temperature of the preliminary heating rollers 31 to 34 is set to a temperature equal to or higher than the glass transition point of the yarn 100 (for example, 90°C). The surface temperature of the drawing rollers 41 to 44 is set to a temperature higher than the surface temperature of the preliminary heating rollers 31 to 34 (for example, 110°C). The surface temperature of the heat setting rollers 51 to 56 is set to a temperature higher than the surface temperature of the drawing rollers 41 to 44 (for example, 130°C).

[0068] The surface temperature of the preliminary heating rollers 31 to 34 (for example, 90°C) corresponds to the "first temperature" of the present invention. The surface temperature of the drawing rollers 41 to 44 (for example, 110°C) corresponds to the "second temperature" of the present invention. The surface temperature of the heat setting rollers 51 to 56 (for example, 130°C) corresponds to the "third temperature" of the present invention.

[0069] Note that it is not essential that all of the preliminary heating rollers 31 to 34 be set to the same surface temperature, and they may be set to different surface temperatures for each of the preliminary heating rollers 31 to 34. Similarly, it is not essential that all of the stretching rollers 41 to 44 be set to the same surface temperature, and they may be set to different surface temperatures for each of the stretching rollers 41 to 44. Also, it is not essential that all of the heat setting rollers 51 to 56 be set to the same surface temperature, and they may be set to different surface temperatures for each of the heat setting rollers 51 to 56.

[0070] Also, in this embodiment, the surface temperatures of all of the preliminary heating rollers 31 to 34 are being increased in temperature, but it is not limited to this. For example, among the preliminary heating rollers 31 to 34, the surface temperature of at least one roller may be increased in temperature, and the surface temperatures of the remaining other rollers do not have to be increased in temperature. The same applies to the stretching rollers 41 to 44 and the heat setting rollers 51 to 56.

[0071] Also, the stretching section 28 also includes a first heat insulation box 39, a second heat insulation box 49, and a third heat insulation box 59. The first heat insulation box 39, the second heat insulation box 49, and the third heat insulation box 59 are all formed of a heat insulating material. The preliminary heating rollers 31 to 34 are housed in the first heat insulation box 39, the stretching rollers 41 to 44 are housed in the second heat insulation box 49, and the heat setting rollers 51 to 56 are housed in the third heat insulation box 59. In this way, heat radiation from each roller is suppressed. In this embodiment, the preliminary heating rollers 31 to 34 are housed in the first heat insulation box 39, the stretching rollers 41 to 44 are housed in the second heat insulation box 49, and the heat setting rollers 51 to 56 are housed in the third heat insulation box 59, but they do not have to be housed in one heat insulation box each. For example, the preliminary heating rollers 31 to 34 may be separately housed in a plurality of first heat insulation boxes 39, the stretching rollers 41 to 44 may be separately housed in a plurality of second heat insulation boxes 49, or the heat setting rollers 51 to 56 may be separately housed in a plurality of third heat insulation boxes 59.

[0072] Note that since the preheating rollers 31 to 34, the stretching rollers 41 to 44, and the heat setting rollers 51 to 56 are each housed in their respective heat insulation boxes 39, 49, and 59, they would not originally be shown in the drawings, but are shown in each of the figures referred to in this specification for the sake of convenience.

[0073] In this embodiment, 4 preheating rollers, 4 stretching rollers, and 6 heat setting rollers are arranged respectively, but the number of each roller is not limited to this, and the number of rollers can be changed according to the application.

[0074] Next, a mode in which the yarn 100 is sent from any one of the first heat insulation box 39, the second heat insulation box 49, and the third heat insulation box 59 to another heat insulation box on the downstream side will be described with reference to FIG. 6. FIG. 6 is an example of a side view showing an outline of a mode in which the yarn 100 is sent from the first heat insulation box 39 to the second heat insulation box 49. In FIG. 6, cross-sections that can be seen when the first heat insulation box 39 and the second heat insulation box 49 are cut in the vertical direction are shown.

[0075] As shown in FIG. 6, an outlet opening 36 is formed in the first heat insulation box 39. An inlet opening 45 is formed in the second heat insulation box 49. The outlet opening 36 and the inlet opening 45 are not in communication and are separated from each other. That is, the yarn 100 that exits the first heat insulation box 39 from the outlet opening 36 once touches the outside air and then enters the second heat insulation box 49 from the inlet opening 45. The outlet opening 36 corresponds to the "yarn outlet of the first heat insulation box" of the present invention. Also, the inlet opening 45 corresponds to the "yarn inlet of the second heat insulation box" of the present invention.

[0076] In this way, by separating the outlet opening 36 of the first heat insulation box 39 and the inlet opening 45 of the second heat insulation box 49 on the downstream side of the first heat insulation box 39 without connecting them, heat transfer between the first heat insulation box 39 and the second heat insulation box 49 can be suppressed. Although not shown, similarly, the outlet opening of the second heat insulation box 49 and the inlet opening of the third heat insulation box 59 are not connected and are separated from each other. The outlet opening of the second heat insulation box 49 corresponds to the "thread outlet of the second heat insulation box" of the present invention. Also, the inlet opening of the third heat insulation box 59 corresponds to the "thread inlet of the third heat insulation box" of the present invention.

[0077] [2-3. Relaxing section] FIG. 7 is an example of a side view showing the periphery of the relaxing section 60, the second guide part 70, and the winding part 8. As shown in FIG. 7, the relaxing section 60 is disposed directly above the heat setting rollers 53 to 56.

[0078] The relaxing section 60 includes a first relaxing roller 61, a second relaxing roller 62 disposed on the downstream side in the thread running direction from the first relaxing roller 61, and a fourth heat insulation box 69. Both the first relaxing roller 61 and the second relaxing roller 62 are rollers having an axial direction in a direction substantially orthogonal to the thread running direction of the thread path in a plan view (i.e., the Y direction).

[0079] The thread 100 sent out from the heat setting roller 56 on the most downstream side among the heat setting rollers 51 to 56 runs in the order of the first relaxing roller 61 and the second relaxing roller 62.

[0080] The first relaxing roller 61 and the second relaxing roller 62 are arranged offset from each other in the vertical direction. Also, in the X direction, the first relaxing roller 61 is offset to the X direction side and the second relaxing roller 62 is offset to the side opposite to the X direction side with respect to each other. By arranging the first relaxing roller 61 and the second relaxing roller 62 in this way, the height of the second relaxing roller 62 can be suppressed, and the thread hanging operation on the second relaxing roller 62 can be facilitated.

[0081] The winding angles of the yarn 100 around the first relaxation roller 61 and the second relaxation roller 62 are both less than 360 degrees. The surface temperatures of the relaxation rollers 61 and 62 are set to a temperature lower (e.g., 100 °C) than those of the heat setting rollers 51 to 56 so that the internal strain of the yarn 100 is relaxed. However, it is not essential that the first relaxation roller 61 and the second relaxation roller 62 be set to the same surface temperature, and they may be set to different surface temperatures for each of the relaxation rollers 61 and 62. Also, it is not necessarily required that the surface temperatures of either the first relaxation roller 61 or the second relaxation roller 62 be increased. For example, among the first relaxation roller 61 and the second relaxation roller 62, the surface temperature of at least one roller may be increased, and the surface temperatures of the other rollers do not have to be increased.

[0082] The fourth heat insulation box 69 is formed of a heat insulating material. The two relaxation rollers 61 and 62 are housed in the fourth heat insulation box 69 so that heat dissipation is suppressed. Although not shown, the outlet opening of the third heat insulation box 59 and the inlet opening of the fourth heat insulation box 69 are not in communication with each other and are separated from each other. By doing so, heat transfer between the third heat insulation box 59 and the fourth heat insulation box 69 can be suppressed.

[0083] The yarn 100 sent out from the second relaxation roller 62 disposed on the downstream side in the yarn running direction in the relaxation section 60 is guided by the second guide section 70 after coming out of the fourth heat insulation box 69. The second relaxation roller 62 corresponds to the "guide roller" of the present invention.

[0084] [2-4. Second guide section] Referring to FIGS. 7 and 8, the second guide section 70 will be described. FIG. 8 is an example of a plan view showing the periphery of the second guide section 70.

[0085] The second case interior 70 mainly consists of a plurality (for example, six) of distribution rollers 70A to 70F for the first winding device and a plurality (for example, six) of distribution rollers 70G to 70L for the second winding device (see FIG. 8). The plurality of yarns 100 sent out from the second relaxation roller 62 are sent in two directions, a direction toward the distribution rollers 70A to 70F for the first winding device and a direction toward the distribution rollers 70G to 70L for the second winding device. The distribution rollers 70A to 70F for the first winding device are rollers for changing the traveling direction of the plurality of yarns 100 sent from the second relaxation roller 62 downward for each of the plurality of yarns 100 so as to be directed toward the bobbin 86 mounted on the winding shaft 84 of the first winding device 81 (see FIG. 1). The distribution rollers 70G to 70L for the second winding device are rollers for changing the traveling direction of the plurality of yarns 100 sent from the second relaxation roller 62 downward for each of the plurality of yarns 100 so as to be directed toward the bobbin 86 mounted on the winding shaft 84 of the second winding device 91 (see FIG. 1).

[0086] The distribution rollers 70A to 70F for the first winding device are arranged directly above the first winding device 81. Specifically, the distribution rollers 70A to 70F each correspond to a plurality of shedding devices 85 (see FIG. 7) and a plurality of bobbins 86 (see FIG. 7), and are arranged in series in the X direction directly above the corresponding shedding device 85. Note that the shedding devices 85 are arranged in series along the X direction directly above the corresponding bobbins 86.

[0087] The acute angle formed by the thread running direction of the thread 100 sent from the second relaxation roller 62 to each of the first winding device distribution rollers 70A to 70F and the horizontal plane is preferably 0 degrees or more and 20 degrees or less. By doing so, the heights of the relaxation portion 60 and the second guide portion 70 can be suppressed. However, this is not essential. The acute angle formed by the thread running direction of the thread 100 sent from the second relaxation roller 62 to each of the first winding device distribution rollers 70A to 70F and the horizontal plane may be, for example, a negative angle, or may be an angle slightly exceeding 20 degrees as long as the height of the second relaxation roller 62 can be suppressed. The "acute angle formed by the thread running direction of the thread 100 sent from the second relaxation roller 62 to each of the first winding device distribution rollers 70A to 70F and the horizontal plane" corresponds to the angle β shown in FIG. 9. Note that FIG. 9 is an example of a schematic diagram showing the acute angle β formed by the thread running direction of the thread 100 sent from the second relaxation roller 62 to the first winding device distribution roller 70A and the horizontal plane. In FIG. 9, among the plurality of first winding device distribution rollers 70A to 70F, the first winding device distribution roller 70A is illustrated as an example. In the present embodiment, the second relaxation roller 62 is arranged such that the acute angle β formed by the thread running direction of the thread 100 sent from the second relaxation roller 62 to each of the first winding device distribution rollers 70A to 70F and the horizontal plane is, for example, greater than 0 degrees and less than or equal to 20 degrees.

[0088] The thread 100 whose running direction is changed downward by the first winding device distribution rollers 70A to 70F is shed by the corresponding shedding device 85 and wound around the corresponding bobbin 86 to form a winding package.

[0089] Similarly, the second winding device distribution rollers 70G to 70L (see FIG. 8) are arranged directly above the second winding device 91. The second winding device distribution rollers 70G to 70L change the running directions of the plurality of threads 100 sent from the second relaxation roller 62 downward for each of the plurality of threads 100 so as to be directed toward the corresponding bobbins (not shown). The threads 100 whose running directions are changed downward by the second winding device distribution rollers 70G to 70L are shed by the corresponding shedding device (not shown) and wound around the corresponding bobbins to form winding packages.

[0090] [3. Take-up Unit] Referring to FIG. 10, the arrangement (front view) of the take-up unit 8 when viewed in the direction opposite to the X direction will be described. FIG. 10 is an example of a view taken along the arrow B-B shown in FIG. 7.

[0091] As described above, the take-up unit 8 includes a first take-up device 81 and a second take-up device 91, and the first take-up device 81 and the second take-up device 91 are arranged side by side in the Y direction. Also, two take-up shafts 84 of the first take-up device 81 are arranged. Similarly, two take-up shafts 84 of the second take-up device 91 are arranged. Further, the second relaxation roller 62 is arranged such that its position in the Y direction is shifted to the side of the first take-up device 81 with respect to the center line CL of the take-up unit 8. By doing so, the angles of the yarn 100 entering the bobbins 86 attached to the take-up shafts 84 of the first take-up device 81 and the angles of the yarn 100 entering the bobbins 86 attached to the take-up shafts 84 of the second take-up device 91 can be made substantially the same angle.

[0092] In the present embodiment, the length of the main frame 80 in the Y direction is approximately 1000 mm. Also, the oil supply unit 2, the yarn suction unit 4, the first guide unit 10, the first yarn feed roller 20, the stretching unit 28, the relaxation unit 60, and the second guide unit 70 are all arranged within the range in the width direction of the take-up unit 8, more specifically, within a range of approximately half (for example, approximately 500 mm) of the length in the width direction of the main frame 80 (for example, approximately 1000 mm). By doing so, it is possible to make the take-up unit 8 compact in the width direction while securing the working area for the operator. Note that the width direction of the take-up unit 8 corresponds to the direction (i.e., the Y direction) orthogonal to the axial direction and the vertical direction of the take-up shaft 84.

[0093] [4. Operational Effects] According to the spinning and winding device 1 of the present embodiment described above, the stretching unit 28 and the winding unit 8 are horizontally arranged on the same floor such that the axial direction of the winding shaft 84 and the running direction of the yarn 100 in the stretching unit 28 in plan view are parallel. Therefore, the height of the first guide portion 10 disposed above at least one roller of the stretching unit 28 can be reduced, and the spinning and winding device 1 can be made lower in height. As a result, it is not necessary to divide the working area on the first floor vertically as in the prior art and arrange an operator in each working area, and it becomes possible to perform the yarn threading operation by one operator, so that the yarn threading operation time can be shortened and labor saving can be achieved.

[0094] Further, the preliminary heating rollers 31 to 34, the stretching rollers 41 to 44, and the heat setting rollers 51 to 56 are arranged in two or three in the vertical direction along the X direction, and further, these rollers are arranged in series in plan view, whereby the stretching unit 28 can be made lower in height. In particular, for example, in a spinning and winding device for industrial material yarns of 300 denier or more, more heating length is required compared to a spinning and winding device for clothing yarns. Moreover, although the number of rollers provided in the stretching unit is increased by setting the winding angle of the yarn 100 around each roller to less than 360 degrees, even in such a case, the spinning and winding device 1 can be made lower in height.

[0095] Further, the first guide portion 10 is disposed directly above the stretching unit 28, and the first yarn feeding roller 20 is disposed at a position offset from both the first guide portion 10 and the stretching unit 28 on the side opposite to the X direction. Therefore, the vertical distance between the first guide portion 10 and the stretching unit 28 can be reduced, the heights of the first guide portion 10 and the stretching unit 28 can be suppressed, and thus the spinning and winding device 1 can be made lower in height.

[0096] In addition, a plurality of yarns 100 spun downward from the spinning machine are given tension by a plurality of direction-changing rollers 10A to 10L, and the running of the yarns 100 can be stabilized. Furthermore, there is no need for a guide for finely adjusting the tension on the yarns as provided conventionally, and accordingly, the oil supply section 2 and the yarn suction section 4 can be arranged at a lower position, and thus the spinning take-up device 1 can be made to have a lower floor. Moreover, since the running direction of the yarns 100 is changed by the rollers, the burden on the yarns 100 can be reduced as much as possible.

[0097] In addition, the plurality of direction-changing rollers 10A to 10L are each arranged with a shift in the Y direction. Therefore, while reducing the vertical distance between the first guide section 10 and the stretching section 28 and suppressing the height of the first guide section 10, it is possible to prevent the plurality of yarns 100 from interfering with or getting entangled with each other.

[0098] In addition, the plurality of direction-changing rollers 10A to 10L are each provided with a plurality of motors (not shown) corresponding to each roller so that each can be individually driven. Therefore, even if the distances from the respective direction-changing rollers 10A to 10L to the first yarn feed roller 20 are different, it is possible to reduce the tension difference between the plurality of yarns 100.

[0099] In addition, according to the spinning take-up device 1 of the present embodiment, the first yarn feed roller 20, the preliminary heating rollers 31 to 34, the stretching rollers 41 to 44, the heat setting rollers 51 to 56, and the relaxation rollers 61, 62 all have a winding angle of the yarn 100 of less than 360 degrees. Also, the axial direction of each of the above rollers is a direction substantially orthogonal to the yarn running direction of the yarn 100 in plan view (that is, the Y direction). Therefore, the plurality of yarns 100 run while maintaining parallelism between the first guide section 10 and the second relaxation roller 62, and the running direction in plan view is the X direction or the direction opposite to the X direction. Thus, the plurality of yarns 100 can be made to run so that the yarn path from the first guide section 10 to the second relaxation roller 62 does not shift in the axial direction of each roller (that is, the Y direction).

[0100] Further, according to the spinning take-up device 1 of the present embodiment, the outlet opening of the Nth heat preservation box and the inlet opening of the (N + 1)th heat preservation box arranged on the downstream side of the Nth heat preservation box are separated without communication. By doing so, heat transfer between the Nth heat preservation box and the (N + 1)th heat preservation box can be suppressed. Note that N is a natural number with (the number of heat preservation boxes - 1) as the upper limit.

[0101] In addition, since the spinning take-up device 1 of the present embodiment is compact not only in the vertical direction but also in the width direction of the winding unit 8, space saving and work efficiency improvement of the entire spinning take-up device 1 can be achieved.

[0102] [5. Modification Example] Next, a modification example in which various changes are made to the spinning take-up device 1 of the present embodiment will be described. However, in describing the modification example, those having the same configuration as the above-described embodiment will be given the same reference numerals and their description will be omitted as appropriate.

[0103] [5-1. First Modification Example] In the above-described embodiment, for example, as shown in FIG. 2, a plurality of oil supply parts 2, a plurality of yarn suction parts 4, and a first guide part 10 are arranged directly above the stretching part 28, but it is not limited thereto. For example, in the spinning take-up device 1A shown in FIG. 11, a plurality of oil supply parts 2, a plurality of yarn suction parts 4, and a first guide part 10 are arranged at a position deviated in the direction opposite to the X direction from either the stretching part 28 or the first yarn feed roller 20, rather than directly above the stretching part 28.

[0104] Although the spinning take-up device 1A according to the first modification example has a longer length in the X direction than the spinning take-up device 1 described in the above-described embodiment, the stretching part 28 can be made lower. Furthermore, since the yarn 100 can be made to travel in one direction, it is also possible to reduce the load of the yarn winding operation.

[0105] [5-2. Second Modification Example] In the above-described embodiment, for example, as shown in FIG. 5, the preheating rollers 31 to 34 are accommodated in the first heat-insulating box 39, the stretching rollers 41 to 44 are accommodated in the second heat-insulating box 49, and the heat-setting rollers 51 to 56 are accommodated in the third heat-insulating box 59.

[0106] Incidentally, depending on the stretching process, the thread brand, etc., it may be necessary to change the number of all or some of the preheating rollers, stretching rollers, heat-setting rollers, and relaxation rollers.

[0107] As an example of the case where the number of all or some of the preheating rollers, stretching rollers, heat-setting rollers, and relaxation rollers is changed according to a change in the thread brand or the like, there are cases where the total number of rollers is not changed and cases where the total number of rollers is changed.

[0108] When the total number of rollers is not changed, although it is necessary to make the mounting pitches of all the rollers the same distance, the number of rollers in each roller group (preheating rollers, stretching rollers, heat-setting rollers, and relaxation rollers) can be changed by simply changing the heat-insulating box while keeping the rollers as they are. For example, in the case where there were 4 preheating rollers, 4 stretching rollers, 6 heat-setting rollers, and 2 relaxation rollers, and the heat-insulating box is changed to have 2 preheating rollers, 4 stretching rollers, and 8 heat-setting rollers. In this case, the heat-insulating box for accommodating the preheating rollers is changed from the heat-insulating box for 4 rollers to the heat-insulating box for 2 rollers, and the heat-insulating box for accommodating the heat-setting rollers is changed from the heat-insulating box for 6 rollers to the heat-insulating box for 8 rollers. The heat-insulating box for accommodating the stretching rollers remains the same for 4 rollers, but the rollers themselves to be accommodated are changed. Thus, when the total number of rollers is not changed, it is possible to easily perform the recombination of the rollers according to the application simply by changing the heat-insulating box.

[0109] When changing the total number of rollers, for example, by unitizing a roller, a heat-insulating box, and a motor for driving the roller, and configuring the unitized components to be attachable to the main body frame 90, it is possible to change the number of all or some of the preheating rollers, stretching rollers, heat-setting rollers, and relaxation rollers. Hereinafter, a specific example of changing the total number of rollers will be described with reference to FIG. 12. FIG. 12 is an example of a side view showing the outline of a spinning take-up device according to the second modification, and FIGS. (a) to (c) are diagrams showing an example of a recombination pattern of each roller.

[0110] In the example shown in FIG. 12, for example, by unitizing a roller, a heat-insulating box, and a motor for driving the roller and configuring them to be attachable to the main body frame 90, the number of various rollers can be arbitrarily changed within the region of the stretching unit 28. In particular, since the stretching unit 28 is horizontally arranged on the same floor as the winding unit 8, it is possible to easily perform the recombination of the rollers. In the example shown in FIG. 12, for example, a unit including four rollers is removed and a unit including two rollers is attached. Hereinafter, examples of the unit will be described.

[0111] On the main body frame 90 of the spinning take-up device 1B shown in FIG. 12(a), a preheating roller unit 30, a stretching roller unit 40, and a heat-setting roller unit 50 are set. The number of the preheating rollers, stretching rollers, and heat-setting rollers shown in FIG. 12(a) is the same as that of the spinning take-up device 1 described in the above embodiment.

[0112] The preheating roller unit 30 is a unitized combination of four preheating rollers 31 to 34, a first heat-insulating box 39 capable of accommodating the four preheating rollers 31 to 34, and four motors (not shown) connected to each of the four preheating rollers 31 to 34.

[0113] The stretching roller unit 40 is a unitized assembly consisting of four stretching rollers 41 to 44, a second heat insulation box 49 capable of accommodating the four stretching rollers 41 to 44, and four motors (not shown) each connected to one of the four stretching rollers 41 to 44.

[0114] The heat setting roller unit 50 is a unitized assembly consisting of six heat setting rollers 51 to 56, a third heat insulation box 59 capable of accommodating the six heat setting rollers 51 to 56, and six motors (not shown) each connected to one of the six heat setting rollers 51 to 56.

[0115] On the main body frame 90 of the spinning take-up device 1B shown in Fig. 12(b), a preheating roller unit 30A, a stretching roller unit 40, and a heat setting roller unit 50A are set.

[0116] The preheating roller unit 30A is a unitized assembly consisting of two preheating rollers 31, 32, a first heat insulation box 39A capable of accommodating the two preheating rollers 31, 32, and two motors (not shown) each connected to one of the two preheating rollers 31, 32.

[0117] The stretching roller unit 40 is as described above.

[0118] The heat setting roller unit 50A is a unitized assembly consisting of four heat setting rollers 51 to 54, a third heat insulation box 59A capable of accommodating the four heat setting rollers 51 to 54, and four motors (not shown) each connected to one of the four heat setting rollers 51 to 54.

[0119] On the main body frame 90 of the spinning take-up device 1B shown in Fig. 12(c), a preheating roller unit 30A, a stretching roller unit 40A, and a heat setting roller unit 50B are set.

[0120] The preheating roller unit 30A is as described above.

[0121] The stretching roller unit 40A is a unitized assembly consisting of two stretching rollers 41 and 42, a second heat-insulating box 49A capable of accommodating the two stretching rollers 41 and 42, and two motors (not shown) each connected to one of the two stretching rollers 41 and 42.

[0122] The heat-setting roller unit 50B is a unitized assembly consisting of eight heat-setting rollers 51 to 58, a third heat-insulating box 59B capable of accommodating the eight heat-setting rollers 51 to 58, and eight motors (not shown) each connected to one of the eight heat-setting rollers 51 to 58.

[0123] In this way, even when changing the total number of rollers, by preparing in advance a plurality of units with different numbers of rollers that can be attached to the main body frame 90, and reorganizing the units according to the stretching process, yarn brand, etc. and setting them on the main body frame 90, it becomes possible to easily perform the recombination of rollers according to the application. In particular, in a conventional spinning take-up device where the stretching section was arranged on an upper floor, it was difficult to recombine each roller. However, in a spinning take-up device where the stretching section 28 is horizontally arranged on the same floor as the winding section 8, by preparing in advance a unit that can be arbitrarily attached to the main body frame 90 using the area of the stretching section 28, the roller recombination work can be made even easier.

[0124] When reorganizing the preheating roller unit 30, the stretching roller unit 40, or the heat-setting roller unit 50 into another unit, disconnect and reconnect the motor connection wiring and replace it with another unit. If the number of rollers in the unit after replacement is less than the number of rollers in the unit before replacement, there will be excess motor wiring. Therefore, it may be possible to tidy up the wiring by providing empty sockets corresponding to the reduced number of rollers and connecting the wiring thereto.

[0125] Although the unitization of the relaxation rollers was not described in the second modification example, similar to the preheating rollers, stretching rollers, and heat setting rollers, the relaxation rollers can also be attached to the main body frame 90, and a plurality of units with different numbers of relaxation rollers may be prepared in advance.

[0126] In addition, when the roller to be recombined is a preheating roller, the preheating roller unit 30 corresponds to the "first unit" of the present invention, and the preheating roller unit 30A corresponds to the "second unit" of the present invention. Further, when the roller to be recombined is a stretching roller, the stretching roller unit 40 corresponds to the "first unit" of the present invention, and the stretching roller unit 40A corresponds to the "second unit" of the present invention. Similarly, when the roller to be recombined is a heat setting roller, the heat setting roller unit 50 corresponds to the "first unit" of the present invention, and the heat setting roller unit 50A or the heat setting roller unit 50B corresponds to the "second unit" of the present invention.

[0127] [5-3. Third Modification Example] In the above-described embodiment, for example, as shown in FIG. 2, the preheating rollers 31 to 34, the stretching rollers 41 to 44, and the heat setting rollers 51 to 56 are arranged along the X direction on the same floor. Further, for example, as shown in FIG. 7, the relaxation unit 60 is arranged directly above the heat setting rollers 53 to 56. However, the positional relationship among the preheating rollers 31 to 34, the stretching rollers 41 to 44, the heat setting rollers 51 to 56, and the relaxation rollers 61 and 62 is not limited to the above, and may be the positional relationship shown in FIG. 13, for example.

[0128] FIG. 13 is an example of a side view showing an outline of a spinning take-up device C according to a third modification. In the spinning take-up device 1C shown in FIG. 13, the stretching unit 28 and the relaxation unit 60 are horizontally arranged. More specifically, the first relaxation roller 61 and the second relaxation roller 62 are arranged side by side along the X direction on the same floor as the heat setting rollers 51 to 56. That is, it is not essential that the relaxation unit 60 is arranged above, for example, the heat setting rollers 51 to 56. However, in this case, it is preferable to arrange the second yarn feed rollers 94 and 95 between the second relaxation roller 62, which is the most downstream roller in the relaxation unit 60, and the second guide unit 70 above the running direction of the yarn 100, that is, above the relaxation unit 60. In this case, the second yarn feed roller 95 corresponds to the " Second yarn feeding roller" of the present invention. As described above, the second relaxation roller 62 corresponds to the "guiding roller" of the present invention By doing so, the yarn 100 can be smoothly fed from the second yarn feed roller 95, which is the most downstream one of the second yarn feed rollers 94 and 95, toward the second guide unit 70. Note that the number of the second yarn feed rollers is not limited to two. One may be used, or three or more may be used. The number of the second yarn feed rollers can be appropriately selected according to the contact angle and contact area of the yarn wound around the circumferential surfaces of the second relaxation roller 62 and each of the second yarn feed rollers.

[0129] Also in the spinning take-up device 1C according to such a third modification, it is preferable that the second guide unit 70 is arranged above the winding unit 8 such that the acute angle formed by the yarn running direction of the yarn 100 sent from the second relaxation roller 62 to each of the distribution rollers 70A to 70L and the horizontal plane is 0 degrees or more and 20 degrees or less.

[0130] [5-4. Fourth Modification Example] In the above-described embodiment, for example, as shown in FIG. 2, the first guide part 10 is disposed near the upper part of the stretching part 28, the yarn suction part 4 is disposed directly above the first guide part 10, and the oil supply part 2 is disposed directly above the yarn suction part 4. Further, the stretching part 28 is horizontally disposed with the winding part 8 (see FIG. 1), and the preliminary heating rollers 31 to 34, the stretching rollers 41 to 44, and the heat setting rollers 51 to 56 are horizontally disposed in series in the X direction on the same floor. Further, two or three rollers of the preliminary heating rollers 31 to 34, the stretching rollers 41 to 44, and the heat setting rollers 51 to 56 are disposed close to each other in the vertical direction. However, the positional relationship among the oil supply part 2, the yarn suction part 4, the first guide part 10, the stretching part 28, and the winding part 8 is not limited to the above, and may be the positional relationship shown in FIG. 14 including the relaxation part 60, for example.

[0131] FIG. 14 is an example of a side view showing the periphery of the first guide part 10 and the extension part 28A according to the fourth modification. Although the winding part 8 is not shown in FIG. 14, in the fourth modification, the extension part 28A includes at least one or more lower rollers horizontally arranged in series in the X direction on the same floor as the winding part 8 (see FIG. 1 etc.), and at least one or more upper rollers arranged at the same height as the oil supply part 2 and the yarn suction part 4. That is, for example, instead of arranging all of the plurality of rollers 31 to 34, 41 to 44, 51 to 56 (see FIG. 5) provided in the extension part 28 shown in FIG. 2 horizontally with the winding part 8, among the plurality of rollers 31 to 34, 41 to 44, 51 to 56 provided in the extension part 28A, some rollers may be arranged horizontally with the winding part 8, and other rollers may be arranged at the same height as the oil supply part 2 and the yarn suction part 4. Note that the first guide part 10 is arranged near the upper part of at least one or more lower rollers provided in the extension part 28A. Further, the yarn suction part 4 is arranged directly above the first guide part 10, and the oil supply part 2 is arranged directly above the yarn suction part 4. Furthermore, the first yarn feed roller 20 is arranged at a position deviated from the first guide part 10 and the extension part 28A on the side opposite to the X direction. In this way, even if the positional relationship of the oil supply part 2, the spinning suction part 4, the first guide part 10, the first yarn feed roller 20, and each of the rollers 31 to 34, 41 to 44, 51 to 56 (see FIG. 5) provided in the extension part 28A is the positional relationship shown in FIG. 14 for example, the height of the spinning take-off device can be suppressed and the floor can be made lower.

[0132] Note that in FIG. 14, for example, 15 lower rollers and, for example, 9 upper rollers are shown, but the number of rollers is not limited to this. Further, the extension part 28A includes at least one or more preheating rollers, at least one or more stretching rollers, and at least one or more heat setting rollers. Regarding how many of each of the preheating rollers, stretching rollers, and heat setting rollers to use, it can be appropriately determined according to the stretching process, the brand of the yarn, etc. Also, at least one or more of each of the preheating rollers, stretching rollers, and heat setting rollers may be used as the upper rollers, or only any one of the preheating rollers, stretching rollers, and heat setting rollers may be used as the upper rollers.

[0133] Also, for example, in the case of the spinning take-up device 1A shown in FIG. 11, it is a region that is directly above the stretching part 28 and is vacant between the oil supply part 2, the yarn suction part 4, the first guide part 10, and the relaxation part 60. Therefore, in the case of the spinning take-up device 1A shown in FIG. 11, among the plurality of rollers 31 to 34, 41 to 44, 51 to 56 provided in the stretching part 28A, some of the rollers may be arranged horizontally with the winding part 8, and for the other rollers, a part of the plurality of rollers provided in the stretching part 28 may be arranged in the above-mentioned vacant region.
