Description

  The present invention relates to a novel sample warping machine with a yarn recovery mechanism capable of performing warping by simultaneous warping of a plurality of yarns according to preset pattern data (yarn arrangement order, color yarn arrangement order).

  As a sample warper used conventionally, for example, a structure disclosed in Patent Document 1, that is, a fixed creel that stands a plurality of bobbins wound with different types of yarns (different colors or different twists), It is known that a yarn is wound around a warping drum by a yarn guide while changing a yarn by a yarn selecting device according to preset pattern data (yarn arrangement order, color yarn arrangement order).

  In addition, a rotary creel is used and the yarn changing process is omitted, so that there is no time loss during yarn changing and multiple yarns can be wound around the warping drum at the same time, further reducing the warping work time. Sample warping machines capable of simultaneously warping multiple numbers are also known (Patent Document 2, Patent Document 3 and Patent Document 4).

  The fixed creel has a plurality of bobbins wound with the same type and / or different types of yarn, and can warp each yarn while changing the yarn freely by the selection device. There is an advantage that the warping work of the pattern warping can be performed, but there is a disadvantage that it takes a long time for the warping work to wind one yarn around the warping drum sequentially. On the other hand, the rotary creel has a plurality of bobbins wound with the same type and / or different types of yarns, and has a solid warp (for example, one color of red yarn), one-to-one (for example, red 1 and white 1). 2 repetitions (for example, 2 repetitions of red and 2 repetitions, 2 repetitions of S and 2 rotations of Z), etc. It can be used for repetitive warping of patterns. This rotary creel has the disadvantage that it is not possible to perform warping work other than limited pattern warping, but it takes a lot of warping time to wind multiple yarns around the warping drum at the same time. There is an advantage that it is shortened.

  In the above-described conventional sample warping machine, one or a plurality of yarn guides rotatably and radially attached to the front surface of the warping drum, a fixed creel installed corresponding to the yarn guide, and / or Alternatively, the rotating creel and the yarn selection device for exchanging the yarn supplied to the yarn guide have an essential basic structure.

On the other hand, there has also been proposed a pattern warp partial warping machine that performs winding of a yarn and stopping of winding of the yarn without using a yarn selection device (Patent Documents 5 and 6). There have been problems such as wasteful consumption of the yarn, and smooth switching between yarn winding and yarn winding suspension.

A slide rail 40 is provided on the upper surface of the slide base 38 in a direction parallel to the main shaft pipe 34. A rotating creel frame 42 is movably mounted on the slide rail 40 via a slide block 41 so as to be able to contact and separate from the warper frame 30.

  A drive shaft 44 is rotatably installed on the upper surface of the rotating creel frame 42 via a bearing metal 43. The drive shaft 44 is driven by a drive motor 48 via a pulley belt 46. A rotating creel 50 is attached to the drive shaft 44, and the rotating creel 50 rotates with the rotation of the drive shaft 44. The rotary creel 50 has a support plate 53, on which a plurality of bobbins 52 wound with different and / or the same type of yarn 54 can be set up. A guide plate 56 is provided in front of the bobbin 52 via a support shaft 58 and guides the thread 54 from the bobbin 52.

  A plurality of yarn guides 60 are attached to the tip of the drive shaft 44, and the yarn guide 60 rotates coaxially with the rotary creel 50 as the drive shaft 44 rotates. The yarn guide 60 includes a long yarn guide arm 62, a yarn guide position converting device 64 attached to the tip of the yarn guide arm 62, and a yarn guide member 66 attached to the yarn guide position converting device 64. ing. In the illustrated example shown in FIGS. 1 to 6, the yarn winding switching means includes the yarn guide position converting device 64 and the yarn guide member 66, and the winding for winding the yarn 54 drawn out from the bobbin 52 around the warp drum 12. The operation is divided into the attaching yarn 54 and the rest yarn 54 that is not wound around the warping drum 12 (the rest yarn may be indicated as 54a).

  As shown in FIG. 6, the yarn guide member 66 can be displaced with a rotation angle α to the yarn winding position P1 and the yarn winding pause position P2 by the action of the yarn guide position converting device 64, and as required. Accordingly, a known aligned winding operation can be performed. The displacement of the yarn guide member 66 by the yarn guide position converting device 64 is performed on a motor, a solenoid, a cylinder, or the like built in the device 64. Therefore, as will be described later, when the yarn guide member 66 is at the yarn winding position, the yarn 54 is wound, and when the yarn guide member 66 is at the yarn winding pause position, the yarn 54 is not wound. Thus, the yarn is automatically wound and paused according to the set yarn order, and the yarn 54 is wound on the warping drum 12. In FIG. 6, 66 a is a guide hole provided at the tip of the yarn guide 60, that is, the tip of the yarn guide member 66.

  4 and 5, 67a to 67f are twill bars (67a is a cut upper bar, and 67b is a cut lower bar). Note that the basic configuration and operation of the sample warper 10 are widely known from the above-mentioned patent publications and the like, and detailed description of the known configuration and operation is omitted.

A yarn collection guide 70 is provided outside the central portion of the outer drum plate 16 of the warping drum 12 via a support rod 68. A yarn collection hole 72 is formed in the center of the yarn collection guide 70. Reference numeral 74 denotes a yarn take-up reel driven by a motor or the like, which collects and winds the rest yarn 54a guided from the yarn collection hole 72 to the back side of the yarn collection guide 70 and the warp starting work yarn 54a. The rotation of the yarn winding reel 74 is preferably performed in direct proportion to the rotation of the rotary creel 50. The yarn collection guide 70 and the yarn take-up reel 74 constitute a yarn collection mechanism. In FIG. 4, 76a and 76b are yarn cutting devices, which are installed on or near the lines connecting the cut upper bar 67a, the cut lower bar 67b and the yarn collection hole 72, respectively. The yarn cutting device 76a cuts the yarn 54a _{1 in} which the yarn 54 has changed from the winding suspension state to the winding state, and the yarn cutting device 76b has the yarn 54a in which the yarn 54 has changed from the winding state to the winding suspension state. Performs the action of cutting ₂ .

The operation of the above configuration will be described. Prior to the start of the warping operation, all the yarns 54 pulled out from the bobbin 52 are passed through the guide holes 66a at the tip of the yarn guide 60, as shown in FIG. Since it is a yarn, it is indicated by 54a in the drawing) and is wound and fixed to the yarn take-up reel 74 through the yarn collection hole 72 of the yarn collection guide 70. Warping is started from this state. In other words, the yarn guide member 66 designated by preset pattern data (yarn arrangement order, color yarn arrangement order) is rotated to the vicinity of the cut inferior bar 67b and displaced to the winding position P1, whereby the warp drum 12 is moved. winding is started, the winding (the trajectory of the thread 54a ₁ in FIG. 4) to start the yarn of the yarn guide 66 each yarn guide 66 after one revolution or more, is cut by the cutting device 76a.

Next, when the yarn 54 being wound (yarn of the yarn guide 66 at the position P1 in FIG. 4) is temporarily unnecessary according to preset pattern data (yarn arrangement order, color yarn arrangement order), it is designated. by yarn guide member 66 displaces the yarn guide member 66 when traveling in the vicinity of the cut Ayaka bar 67b to wind and the rest position P2, as the yarn 54 is rotated in the yarn guide 60, the yarn of FIG. 4 54a ₂ Is wound around the thread take-up reel 74 along with other rest yarns 54a. The yarn 54a _{2 that} has become the rest yarn is cut after the yarn guide 60 corresponding to the yarn has passed three or more revolutions. One end of the cut yarn is wound around the yarn take-up reel 74 while being twisted with another resting yarn 54a, and warping proceeds while the one end of the cut yarn remains free. If this yarn is needed again according to preset data, the warp drum 12 is again moved by displacing the yarn guide member 66 to the winding position P1 when the yarn guide member 66 advances to the vicinity of the cut lobe bar 67b. Winding around is started. The warping proceeds for the other yarn guides 60 by sequentially performing the same operations using preset pattern data.

  As described above, both the conversion operation from the yarn winding pause state to the yarn winding state and the conversion operation from the yarn winding state to the yarn winding pause state can be smoothly performed while minimizing waste of the yarn, and simultaneous warping of multiple yarns. It is possible to efficiently perform the pattern warping by the method in a short time.

  In the embodiment shown in FIGS. 1 to 6, an example in which the rotating creel 50 and the yarn guide 60 are integrally mounted on the drive shaft 44 is shown. However, the rotating creel 50 and the yarn guide 60 are shown. Can be installed separately and rotated in synchronism with each other.

  Furthermore, in the present invention, a guide rod is attached to the end of the warping drum on the outer drum plate side, and the guide rod is used as the yarn winding switching means or the yarn winding switching means from the yarn winding switching means. May be adopted, and will be described below with reference to FIGS.

FIG. 10 is an explanatory view showing a state where the yarn guide opening is closed by the movable piece. FIG. 11 is an explanatory diagram showing the position of the movable piece and the yarn trajectory when the rest yarn is switched to the winding state.

  In FIG. 7, reference numeral 80 denotes a guide rod having a ring-shaped guide rod main body 82 attached to the end of the warping drum 12 on the outer drum plate 16 side. A thread guide opening 84 is formed in a part of the guide rod body 82 so as to open. The opening position of the yarn guide opening 84 is set so as to be positioned between the cut upper bar 67a and the cut lower bar 67b as shown in FIG. A movable piece 86 is rotatably attached to one end edge of the yarn guide opening 84 so that the yarn guide opening 84 can be opened and closed with respect to the yarn guide rotation direction. The movable piece 86 includes a neutral direction (FIG. 10) for closing the guide opening 84, a resting direction (FIGS. 8 and 9) for drawing the wound yarn into the rest yarn raceway, and a rest yarn for the winding yarn raceway. It is possible to displace in at least three directions of the winding direction (FIG. 11) to be drawn out. By using this guide rod 80, it is possible to easily switch from the winding yarn to the rest yarn or from the rest yarn to the winding yarn.

When switching the winding yarn to the pause yarn, as shown in FIGS. 8 and 9, the movable piece 86 is displaced in the pause direction (that is, the warping drum 12 direction) in which the winding yarn is drawn into the raceway of the pause yarn. The thread guide opening 84 is opened, and the thread 54 (winding thread) being wound is drawn in the resting direction by the movable piece 86 from the thread guide opening 84 to become the resting thread 54a. After a predetermined time has passed, the track moves to the track B, twisted together with other pause yarns (not shown) as in the case of the pause yarn 54a described above, and wound around the yarn take-up reel 74 through the yarn collection hole 72.

  When the rest yarn is switched to the wound yarn, as shown in FIG. 11, the movable piece 88 is displaced in the winding direction (that is, the direction of the rotating creel 50) for drawing the rest yarn into the winding yarn path, and thereby the yarn guide. With the opening 84 opened, the paused yarn (resting yarn) 54 a is pulled out from the guide opening 84 in the winding direction by the movable piece 86, and is wound around the warping drum 12 by the yarn guide 60.

  In this way, the guide rod 80 can switch from the wound yarn to the rest yarn, or from the rest yarn to the winding yarn, so that the yarn guide 60 is always set in the winding state and the yarn winding switching is performed. The yarn guide 60 can be displaced between a yarn winding state and a yarn winding halt state, and can be used as a yarn trajectory changing unit.

When the guide rod 80 is used as the yarn winding switching means, the action of each member and the variation of the yarn trajectory are performed in the same manner as when the yarn guide 60 described above is used as the yarn winding switching means. Is omitted, for example, the yarn 54a _{1 that has been in the} winding state from the yarn winding pause state and the yarn 54a ₂ that has been in the winding pause state from the winding state are similarly cut by the above-described yarn cutting devices 76a and 76b. .
