Description

  The present invention relates to an automatic winder.

  2. Description of the Related Art Conventionally, an automatic winder having a yarn winding unit that winds a spun yarn around a package is known. Patent Document 1 discloses an automatic winder of this type. The automatic winder of Patent Document 1 includes a split including an upper frame in which a winding frame that supports a winding structure (yarn winding unit) is disposed at the uppermost portion, and a middle frame that is disposed in a lower portion of the upper frame. It has a frame structure. In the middle frame, an electronic board or an electronic component for controlling the operating state of each device is accommodated.

  In the automatic winder of Patent Document 1, in order to improve the robustness of the winding frame, the upper frame and the middle frame are joined in a state of surface contact with each other. According to this configuration, the vibration generated when the winding structure is continuously driven at high speed is suppressed (the shock is absorbed) because the upper frame is firmly fixed to the middle frame. It is thought that vibration of the upper frame is prevented. According to Japanese Patent Laid-Open No. 2004-228688, this configuration makes it possible to prevent the yarn winding in the package from being arranged, and to prevent parts of each device such as the middle frame from being damaged and failing to perform yarn joining accurately.

JP 2013-67444 A

  However, in the configuration of Patent Document 1, when the vibration generated in the winding structure is large and the shock cannot be absorbed by the structure of the frame alone, the vibration of the winding structure is transferred to the middle frame through the upper frame. As a result, there is a possibility that an electronic board (unit controller) disposed inside the middle frame may be adversely affected. Electronic substrates and the like are generally weak against vibration and shock, and it has been desired to take some measures against vibration.

  The present invention has been made in view of the above circumstances, and an object thereof is to protect a unit controller from vibration in an automatic winder.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

The yarn processing unit includes a mechanism for piecing and is attached to the main frame at a position different from a position at which the yarn winding unit is attached to the main frame. The unit controller is disposed in the yarn processing unit and controls the yarn winding unit and the yarn processing unit.

  As a result, the yarn winding portion that generates a large vibration with the winding of the yarn is attached to the main frame at a position different from the attachment position of the yarn processing portion with respect to the main frame. It is possible to reduce the direct transmission to the part. As a result, a unit controller that is generally vulnerable to vibration and impact can be protected from vibration, and control stability can be ensured.

  The automatic winder preferably has the following configuration. That is, the yarn winding portion is attached to the upper portion of the main frame. The yarn processing unit includes a yarn supply changing unit and a yarn joining unit. The yarn supply changing portion is disposed at a lower portion of the main frame. The yarn joining portion is disposed between the yarn supply changing portion and the yarn winding portion, and joins the yarns supplied from the yarn supply changing portion to the yarn winding portion.

  Thereby, the yarn winding unit, the yarn supply changing unit, and the yarn joining unit are each configured in a modular manner, and it is possible to suppress transmission of large vibrations generated in the yarn winding unit to other modules.

  The automatic winder preferably has the following configuration. That is, the yarn winding unit includes a yarn winding frame. The yarn joining portion of the yarn supply changing portion includes a yarn joining frame. The yarn winding frame and the yarn joining frame are attached to the main frame in a state of being separated from each other.

  Thereby, even if the yarn winding frame vibrates greatly as the yarn is wound, the vibration is not directly transmitted to the yarn joining frame, so that the unit controller can be protected from the vibration.

  In the automatic winder, it is preferable that a cradle for supporting a package for winding the yarn is attached to the yarn winding frame.

  Thereby, since the vibration of the cradle is not directly transmitted to the yarn joining frame, the unit controller can be protected from the vibration.

  In the automatic winder, it is preferable that a yarn monitoring device for monitoring a yarn defect is attached to the yarn joining frame.

  Thereby, the yarn monitoring device that is generally vulnerable to vibration can be protected from vibration. Therefore, the yarn can be sensed with high accuracy by the yarn monitoring device.

  In the automatic winder, it is preferable that a splicer for piecing is attached to the piecing frame.

  Thereby, the splicer can be protected from vibration.

  In the automatic winder, it is preferable that a tension applying device that applies tension to the yarn is attached to the yarn joining frame.

  Thereby, the tension applying device can be protected from vibration.

  In the automatic winder, a space is preferably formed between the yarn winding unit and the yarn processing unit.

  Thereby, it is possible to effectively suppress the large vibration generated in the yarn winding unit from being transmitted to the yarn processing unit, and it is possible to reduce an adverse effect on the unit controller due to the vibration.

  In the automatic winder, it is preferable that the position where the yarn winding unit is attached to the main frame is disposed above the position where the yarn processing unit is attached to the main frame.

  Thereby, the yarn winding unit and the yarn processing unit can be rationally arranged.

  In the automatic winder, a vibration absorbing member for absorbing vibration is provided between at least one of the yarn winding unit and the main frame or between the yarn processing unit and the main frame. It is preferred that

That is, the main frame further includes a blower duct that is disposed in a state of being horizontally bridged between a pair of side plates and that allows a suction flow generated by the yarn processing section to pass therethrough. The yarn processing unit is fixed to the blower duct. A bottom portion on the back side of the yarn winding portion is fixed to a receiving plate that is bridged between the side plates above the blower duct.

  As a result, the yarn winding portion is not mounted on the upper surface of the blower duct but is placed on and fixed to a receiving plate disposed above the blower duct, so that the yarn winding portion is transmitted to the yarn processing portion via the blower duct. Vibration can be suppressed. Thereby, a unit controller can be protected from vibration and the stability of control can be improved.

  The automatic winder preferably has the following configuration. That is, the yarn winding unit includes a cradle that supports a package formed by winding the yarn supplied from the yarn processing unit. A fulcrum of the cradle is disposed above the receiving plate.

  As a result, a large vibration is transmitted to the fulcrum of the cradle as the package rotates, but since this position is arranged in the region above the receiving plate, the blur of the position of the fulcrum can be suppressed. . Therefore, it is possible to effectively protect the unit controller from vibrations and improve control stability.

  The automatic winder preferably has the following configuration. In other words, the position where the cradle supports the package is arranged on the front side of the yarn winding portion with respect to the position where the yarn winding portion is fixed to the receiving plate. The front surface of the yarn winding unit is located behind the front surface of the yarn processing unit.

  Thereby, the backlash of the backing plate can be further suppressed by reducing the amount of protrusion (overhang amount) protruding to the front surface in the yarn winding portion where the large vibration is likely to occur in the portion where the cradle supports the package. As a result, control stability can be improved.

The rotating arm 42 is a long plate-like member, and includes a package set portion 41 at both ends. A central portion 44 of the rotating arm 42 is rotatably supported by a support body 48. The rotating arm 42 rotates about the central portion 44 as a fulcrum, so that the package 7 for unwinding the yarn can be switched to any of the packages 7 set in the package setting portions 41 at both ends. The package supply device 40 is installed on the main frame 2 by placing the bottom of the support 48 on the bottom plate 12.

  An arm traverse type yarn winding device 60 shown in FIGS. 4 and 6 includes a winding bobbin 61, a winding bobbin rotation drive source (not shown), a cradle 62, a contact roller 63, a yarn winding frame 64, and a traverse. An arm 67 and a traverse drive motor 66 are mainly provided. The cradle 62 supports the take-up bobbin 61 to be rotatable. The other components of the yarn winding device 60 including the cradle 62, the winding bobbin rotation driving source, and the traverse driving motor 66 are arranged on the left and right sides of the yarn winding frame 64 and are cantilevered by the yarn winding frame 64. Yes. The traverse arm 67 is driven to reciprocate by a traverse drive motor 66. The contact roller 63 is rotatable in contact with the peripheral surface of the winding bobbin 61.

  The traverse arm 67 performs a reciprocating turning motion as the rotor of the traverse drive motor 66 repeats forward and reverse rotations. As a result, the yarn hooked on the tip of the traverse arm 67 is wound around the winding bobbin 61 that is rotationally driven via the contact roller 63 while being traversed. Thereby, the package 9 which rolled back the package 7 can be formed. A horizontal bottom plate 65 is provided at the bottom on the back side of the yarn winding frame 64. The bottom plate 65 is placed and fixed on the upper surface of the receiving plate 15, whereby the yarn winding device 60 is attached to the main frame 2.

  A yarn storage type yarn joining mechanism 80 shown in FIG. 6 temporarily stores the yarn supplied from the yarn supply exchange unit 3 in a yarn storage unit (accumulator) 81 and then stores it in a core tube (paper tube) in the yarn winding unit 5. The package 9 is formed by winding. The yarn storage unit 81 includes a yarn storage roller 82 capable of winding a yarn. As another configuration, the yarn joining mechanism 80 mainly includes a splicer 83, a yarn monitoring device 84, and a yarn guide member 85.

  The yarn supplied from the yarn supply exchange unit 3 is wound around the yarn storage roller 82 and temporarily stored, whereby the yarn is wound around the core tube (paper tube) in a state where an appropriate tension is applied to the yarn. When a yarn defect is detected by the yarn monitoring device 84, the yarn is immediately cut by a cutter and divided. Then, the lower thread on the yarn supply replacement section 3 side is blown up by a lower thread blowing upper part (not shown) and guided to the splicer 83. The upper yarn on the yarn winding unit 5 side is pulled out while being guided by the yarn guide member 85 and pulled out from the yarn accumulating roller 82. Then, the splicing is performed by the splicer 83 so that the yarn is reconnected and the winding of the yarn is resumed.

  On the left and right sides of the yarn joining frame 86, a yarn accumulating portion 81, a splicer 83, a yarn monitoring device 84, and a yarn guiding member 85 are arranged. The yarn joining frame 86 separates these members into pieces. I support it. The yarn joining frame 86 is positioned in the left-right direction with respect to the winding frame (yarn winding frame 64 in the example of FIG. 6) of the yarn winding unit 5 so as to partition between the yarn joining unit 8 of the adjacent winding unit 4. Arranged together. The winding frame and the yarn joining frame 86 are not directly connected, and a space is formed between them. In other words, the winding frame and the yarn joining frame 86 are arranged with a space in the vertical direction. The yarn joining frame 86 is attached to the yarn joining section 8 so that the stay 87 protruding from the back surface of the yarn joining frame 86 is hooked on the support shaft 14 and the back surface of the yarn joining frame 86 is in contact with the front end surface of the blower duct 13. A unit controller 94 for a yarn storage type yarn joining mechanism is embedded in the back side of the yarn joining frame 86.

  As shown in FIG. 6, when the yarn storage type yarn joining mechanism 80 is attached to the yarn joining portion 8, the vertical dimension of the yarn joining portion 8 is larger than when the yarn joining mechanism 70 is attached. This is because a vertical space is required for the yarn storage roller 82 for storing yarn. Therefore, in the present embodiment, when the yarn storage type yarn joining mechanism 80 is applied to the yarn joining portion 8 so that the yarn storage type yarn joining mechanism 80 can be handled in a modular manner, a dedicated main frame is used. 200 is used as a framework. Thereby, 12 types of winding units 4 can be easily configured by combining with the above-described two types of yarn winding units 5 and the above-described three types of yarn feeding exchange units 3.

  The automatic winder 1 of the present embodiment employs a unique configuration for protecting the unit controller 90 (94) and the winding controller 91 (93) that are vulnerable to vibration and impact. Hereinafter, the configuration for the vibration countermeasure will be described in detail. In the following description, the case where the automatic winder 1 is knitted with modules as shown in FIG. 2 will be described as an example, but the same applies to other knitting cases as shown in FIGS. The configuration is applied.

  As described above, the yarn winding unit 5 is attached to the main frame 2 at a position different from the position where the yarn processing unit 10 is attached to the main frame 2. In other words, the yarn winding unit 5 is indirectly connected to the yarn joining unit 8 via the main frame 2. Therefore, the vibration generated when the yarn winding unit 5 performs the yarn winding operation is transmitted to the yarn joining unit 8 only through the main frame 2. As a result, the unit controller 90 and the winding controller 91 that are generally vulnerable to vibration and impact can be protected from vibration. Further, the yarn monitoring device 71, the splicer 72, and the tension applying device 75 arranged in the yarn joining portion 8 in order from the side closer to the yarn winding portion 5 can be protected from the vibration of the yarn winding portion 5. In particular, the yarn monitoring device 71 is a device that performs sensing and is generally disposed in the vicinity of the yarn winding unit 5 even though it is weak against vibration. The monitoring device 71 can also be well protected from vibration.

  A vibration absorbing member 59 is disposed between the bottom plate 55 of the yarn winding frame 54 and the receiving plate 15. Further, a vibration absorbing member 79 is disposed between the back surface of the yarn joining frame 76 and the blower duct 13. Furthermore, the yarn winding unit 5 and the yarn joining unit 8 are arranged with a gap (interval) therebetween in the vertical direction. Thereby, it is possible to more effectively reduce the vibration accompanying the winding operation of the yarn in the yarn winding unit 5 from being transmitted to the unit controller 90 and the winding controller 91 of the yarn joining unit 8. Similarly, transmission of vibration to the yarn monitoring device 71, the splicer 72, and the tension applying device 75 is also effectively suppressed.

  Here, considering the layout of a textile machine having a yarn winding unit at the top, the configuration is such that the yarn winding unit is fixed to the upper surface of the blower duct, which is the main structure of the main frame. However, in the present embodiment, since the yarn joining portion 8 is fixed to the blower duct 13, if the yarn winding portion 5 is fixed to the blower duct 13, vibration accompanying the rotation of the package 9 in the yarn winding portion 5 It becomes easy to be transmitted to the yarn joining part 8 through the blower duct 13. Therefore, in the present embodiment, the yarn winding portion 5 (specifically, the bottom plate 55 of the yarn winding frame 54) is not the upper surface of the blower duct 13, but the upper surface of the receiving plate 15 that is disposed away from the blower duct 13. Is supported by. With this configuration, vibration transmitted to the yarn joining portion 8 can be suppressed, so that the unit controller 90 inside the yarn joining portion 8 can be protected.

  Furthermore, the yarn winding unit 5 is structurally positioned forward of the position on the back side where the yarn winding unit 5 is supported by the main frame 2 (the mating surface of the bottom plate 55 and the receiving plate 15). A vibration source (position where the winding bobbin 61 or the package 9 and the contact roller 63 are in contact) of the yarn winding unit 5 is disposed. Here, considering the simplification of the layout as much as possible, the amount of forward protrusion of the yarn winding portion 5 is the same as the amount of forward protrusion of the yarn joining mechanism 70, and the front surface of the yarn winding portion 5 is set. A layout that matches the front surface of the yarn joining portion 8 in the front-rear direction can be considered. However, as the weight of the portion where the yarn winding unit 5 is located forward is larger, a larger load is applied to the mating surface between the bottom plate 55 and the receiving plate 15 and the bottom plate 55 becomes loose. In this regard, in this embodiment, even when the tray-type bobbin supply device 30 is used as shown in FIG. 4, the front surface of the yarn winding unit 5 is positioned behind the front surface of the yarn joining unit 8 by a distance P. It is composed. As a result, the forward overhang amount of the yarn winding portion 5 is reduced, and the backlash of the bottom plate 55 is reduced. This also suppresses vibrations transmitted to the main frame 2 (and thus the unit controller 90).

  Furthermore, in this embodiment, the fulcrum 58 of the cradle 52 to which the vibration generated at the vibration source of the yarn winding unit 5 (position where the winding bobbin 61 or the package 9 and the contact roller 63 are in contact) is directly transmitted, It is arranged not in the overhanging area of the yarn winding section 5 but in the area above the receiving plate 15 (area supported from below). Therefore, the position of the fulcrum 58 is stably held, and the blur of the position of the fulcrum 58 can be reduced. Also by this, the backlash of the bottom plate 55 is suppressed, and the vibration transmitted to the main frame 2 (and thus the unit controller 90) can be suppressed.

  As described above, the automatic winder 1 of this embodiment includes the main frame 2, the yarn winding unit 5, the yarn processing unit 10, and the unit controller 90. The yarn winding unit 5 is attached to the main frame 2. The yarn processing unit 10 includes a mechanism for performing yarn splicing and is attached to the main frame 2 at a position different from the position at which the yarn winding unit 5 is attached to the main frame 2. The unit controller 90 is disposed in the yarn processing unit 10 and controls the yarn winding unit 5 and the yarn processing unit 10.

  As a result, the yarn winding portion 5 in which large vibration is generated as the yarn is wound is attached to the main frame 2 at a position different from the attachment position of the yarn processing portion 10 with respect to the main frame 2. Can be reduced from being directly transmitted to the yarn processing unit 10. As a result, the unit controller 90 that is generally vulnerable to vibrations and shocks can be protected from vibrations, and control stability can be ensured.

  In the automatic winder 1 of the present embodiment, a winding controller 91 that is a lower controller of the unit controller 90 and controls the winding operation of the yarn of the yarn winding unit 5 is provided in the yarn processing unit 10 together with the unit controller 90. Be placed.

  Thereby, the winding controller 91 which is the control unit of the yarn winding unit 5 can also be protected from vibration and can stably wind the yarn.

  Further, in the automatic winder 1 of the present embodiment, the yarn winding unit 5 is attached to the upper part of the main frame 2. The yarn processing unit 10 includes a yarn supply exchanging unit 3 and a yarn joining unit 8. The yarn supply exchange unit 3 is disposed at the lower part of the main frame 2. The yarn joining unit 8 is disposed between the yarn supply changing unit 3 and the yarn winding unit 5 and joins the yarns supplied from the yarn supply changing unit 3 to the yarn winding unit 5.

  As a result, the yarn winding unit 5, the yarn supply changing unit 3, and the yarn joining unit 8 are each configured as a module, and large vibrations generated in the yarn winding unit 5 are prevented from being transmitted to the other modules 3 and 8. be able to.

  In the automatic winder 1 of the present embodiment, the yarn winding unit 5 includes a yarn winding frame 54. The yarn joining portion 8 of the yarn feeding exchange portion 3 includes a yarn joining frame 76. The yarn winding frame 54 and the yarn joining frame 76 are attached to the main frame 2 in a state of being separated from each other.

  Thus, even if the yarn winding frame 54 vibrates greatly with the winding of the yarn, the vibration is not directly transmitted to the yarn joining frame 76, so that the unit controller 90 can be protected from the vibration.

  In the automatic winder 1 of the present embodiment, a cradle 52 that supports the package 9 for winding the yarn is attached to the yarn winding frame 54.

  Thereby, the vibration of the cradle 52 is not directly transmitted to the yarn joining frame 76, so that the unit controller 90 can be protected from the vibration.

  In the automatic winder 1 of the present embodiment, a yarn monitoring device 71 that monitors yarn defects is attached to the yarn joining frame 76.

  Thereby, although it is generally weak to a vibration, the thread | yarn monitoring apparatus 71 arrange | positioned in the position close | similar to a vibration source (yarn winding part 5) can be protected from a vibration. Therefore, the yarn monitoring device 71 can sense the yarn with high accuracy.

  Further, in the automatic winder 1 of the present embodiment, a splicer 72 that performs piecing is attached to the piecing frame 76.

  Thereby, the splicer 72 can be protected from vibration.

  In the automatic winder 1 of the present embodiment, a tension applying device (tension applying device) 75 that applies tension to the yarn is attached to the yarn joining frame 76.

  Thereby, the tension applying device 75 can be protected from vibration.

  Further, in the automatic winder 1 of the present embodiment, a space is formed between the yarn winding unit 5 and the yarn processing unit 10.

  Thereby, it is possible to effectively suppress the large vibration generated in the yarn winding unit 5 from being transmitted to the yarn processing unit 10, and it is possible to reduce an adverse effect on the unit controller 90 due to the vibration.

  In the automatic winder 1 of the present embodiment, the position where the yarn winding unit 5 is attached to the main frame 2 (the upper surface of the receiving plate 15) is the position where the yarn processing unit 10 is attached to the main frame 2 ( It is arranged above the support shaft 14).

  Thereby, the yarn winding unit 5 and the yarn processing unit 10 can be rationally arranged.

  Further, in the automatic winder 1 of the present embodiment, vibration is absorbed between the yarn winding unit 5 and the main frame 2 and between the yarn joining unit 8 (yarn processing unit 10) and the main frame 2. Vibration absorbing members 59 and 79 are provided.
