Description

  According to the present invention, a plurality of yarn guide units arranged in series opposite to each other on the front surface of the warping drum are simultaneously used in accordance with pattern data (yarn arrangement order, color yarn arrangement order) set in advance. The present invention relates to a new sample warper with a series yarn guide mechanism capable of warping a pattern by warping.

  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 the yarn is changed by a yarn selecting device according to preset pattern data (yarn order).

  In addition, a rotary creel is used and the yarn changing process is omitted, so 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 a plurality of wires 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 (mainly different types of yarn), and warps each yarn while changing the yarn freely by the selection device. Therefore, there is an advantage that the warping work of the pattern warping can be performed, but there is a disadvantage that it takes much time for the warping work to wind a single yarn around the warping drum. 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 cannot perform the warping work of the pattern warping other than the limited pattern warping, but the warping time is required to wind multiple yarns around the warping drum at the same time. There is an advantage that it is greatly shortened.

  The applicant of the present application is compatible with fixed creel and rotary creel as a sample warper that can shorten the warping time of warping work that requires plain warping and pattern warping and can perform it extremely efficiently. A sample warping machine in which a plurality of yarn selection devices are provided and a combination of pattern warping and repetitive warping has already been proposed (Patent Document 5 and Patent Document 6).

  Further, the applicant of the present application has also proposed a sample warping machine in which a plurality of rotary creels are combined so that pattern warping and repeated warping can be performed freely (Patent Document 7).

In the conventional sample warper as described above, as described in Patent Document 1 to 7, one or a plurality of yarn guide mounted rotatably and radially on the side surface of the warper drum, the yarn The fixed creel and / or rotating creel installed corresponding to the guide and the yarn selection device for exchanging the yarn supplied to the yarn guide have an essential basic structure.

In such a conventional sample warper, the yarn is removed from the yarn guide that winds the yarn on the warping drum when changing the yarn, and the yarn to be wound next is supplied to the yarn guide. Yarn work is indispensable, and there is a lot of time to stop the warping work due to the occurrence of thread loosening until the yarn removed from the yarn guide is collected, thread selection failure, and thread breakage during thread selection. It was. In addition, there is an increasing demand for machines that can warp the pattern warping in a shorter time.
Patent No. 1529104 Japanese Patent No. 1767706 USP 4,972,662 EP375480 JP 2000-136456 A EP933455A2 JP 2002-339183 A JP-A-7-133538

  The inventor has reached the present invention as a result of repeated research to develop a sample warping machine having a novel mechanism that has solved the above-mentioned problems.

  The object of the present invention is to omit the installation of a conventional yarn selection device, and to cause slack in thread replacement, thread selection failure, and yarn breakage stop during thread selection, which has been a problem in the past. It is an object of the present invention to provide a new sample warper with a series yarn guide mechanism that can eliminate the trouble caused by the above and can warp the pattern warping efficiently and in a short time.

  The sample warper with the series yarn guide mechanism of the present invention has a plurality of yarn guide units arranged in series opposite to the front surface of the warping drum, and the yarn feeding unit attached to the yarn guide unit. In accordance with a predetermined yarn arrangement sequence or color arrangement sequence on a conveyor belt that moves the yarn drawn from the bobbin with a predetermined feed amount while the plurality of yarn guide units repeatedly rotate and stop. It is designed to be wound.

  In the sample warper of the present invention, a plurality of yarn guide units arranged in series opposite to the front surface of the warping drum can be freely rotated around the yarn guide main shaft disposed on the front center line of the warping drum. It is preferable to adopt a configuration to be attached to. Further, it is preferable that a motor (preferably a servo motor) is provided for each yarn guide unit as a driving means. Furthermore, it is preferable that the feed amount of the conveyor belt on the warping drum is controlled so as to move while changing according to the number of simultaneous rotations of the yarn guide unit.

  The warping method of the present invention uses a sample warper with a series yarn guide mechanism of the present invention, and a plurality of yarn guide units equipped with yarn feeding bobbins in accordance with a designated yarn arrangement order in accordance with preset pattern data It is characterized by warping the pattern by rotating.

  In the warping method of the present invention, the yarn guide unit equipped with a yarn feeding bobbin that is not required according to the yarn arrangement order is stopped at a predetermined position, and the yarn guide unit equipped with the required yarn feeding bobbin By rotating the, it is possible to always wind a plurality of yarns around the conveyor belt on the warping drum.

  The tip guide member of the yarn guide unit that is temporarily stopped is displaced to a position off the winding track of the warping yarn. Such a configuration is preferable because the tip guide member of the yarn guide unit that is not used does not contact the warping yarn.

  According to the sample warper with the series yarn guide mechanism of the present invention, it is possible to omit the installation of the conventional yarn selection device, the occurrence of yarn loosening at the time of replacing the yarn, which has been a problem in the past, or the failure of the yarn selection In addition, it is possible to eliminate troubles such as stoppage of yarn breakage when selecting a yarn and warp of a pattern by simultaneous warping of a plurality of yarns, thereby achieving an effect that warping can be performed efficiently and in a short time.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. However, the illustrated examples are merely illustrative, and various modifications other than the illustrated examples are possible without departing from the technical idea of the present invention. Needless to say.

  In FIG. 1, a sample warper 10 with a series yarn guide mechanism of the present invention has a base 12, and the base 12 is positioned on a rear side and a warper frame 12 a positioned on the front side. And a yarn guide frame 12b. A warping drum 14 is provided on the warping machine frame 12a. Reference numeral 16 denotes a conveyor belt which is movably installed on the circumferential surface of the warping drum 14. The conveyor belt 16 has its feed amount limited by the conveyor belt feeding means depending on the warping conditions (the number of warps, the warping width, the number of warp windings, etc.), and its movement is synchronized with the rotation of the yarn guide unit described later. At the same time, it changes according to the number of simultaneous rotations of the yarn guide unit.

  Reference numerals 18a to 18h are twilling bars, and there are twilling means at the tip ends of the yarn guides of the tallying bars 18a to 18h. The twilling means can form a yarn twill. More specifically, 18a is a cut upper bar, 18b is an upper bar, 18c and 18d are upper bar, 18e is an upper bar, 18f is an upper bar, 18g is an upper bar, and 18h is a cut upper bar.

  A main shaft pipe 20 supports the warping drum 14. The main shaft pipe 20 is fixedly supported by the warper frame 12a via a main shaft metal (not shown). 2 and 4, reference numeral 21 denotes guide means for performing aligned winding warping. The guide means 21 is described in detail in Patent Document 8 and will not be described again.

  In the sample warper 10 with a series yarn guide mechanism of the present invention, a yarn guide mechanism having a novel configuration is employed, and will be described below. As shown in FIGS. 1 and 2, a stand frame 22 is erected on the front end of the yarn guide frame 12b.

  A yarn guide main shaft 24 is supported and fixed by a first support portion 26 provided on the front surface of the main shaft pipe 20 and a second support portion 28 provided on the upper surface of the stand frame 22. Therefore, the yarn guide main shaft 24 is located on the front center line of the warping drum 14.

A plurality of base rings 30a to 30z are rotatably attached to the yarn guide main shaft 24 at predetermined intervals. The motor support plate 32A～32z in the yarn guide main shaft 24 is vertical set, motor 34a~34z is attached to the motor support plate 32A～32z. Reference numerals 36 a to 36 z denote bosses for fixing the motor support plates 32 a to 32 z to the yarn guide main shaft 24.

  A counter pulley is attached to the base rings 30a to 30z. The counter pulley is connected to motor pulleys coupled to the motor shafts of the motors 34a to 34z by timing belts 38a to 38z. Accordingly, the base rings 30a to 30z are rotated by the rotation of the motors 34a to 34z. As the motors 34a to 34z, a pulse motor, preferably a servo motor, can be used to control rotation, stop, stop holding, and rotation progress angle. In addition, it is preferable to use a toothed belt as the timing belts 38a to 38z.

  Reference numerals 40a to 40z denote bobbin stands attached to the base rings 30a to 30z, and yarn feeding bobbins 42a to 42z can be attached to the bobbin stands 40a to 40z. If a plurality of yarn feeding bobbins can be attached to the bobbin stands 40a to 40z, the yarn feeding can be performed by tying the trailing yarn of the feeding yarn bobbin and the front yarn of the waiting yarn feeding bobbin. This saves the trouble of supplying bobbins and is convenient.

  44a to 44z are yarn guide units installed on the base rings 30a to 30z. The yarn guide units 44a to 44z include a plurality of guide members 48 for guiding the yarn paths of the yarns 46a to 46z drawn from the yarn feeding bobbins 42a to 42z, and yarn guide arms 45a to 45z each having a guide member with holes 50a to 50z. 45z, tip guide members 52a to 52z extended from the guide member 50 with holes, and guide members 54a to 54z with tip holes provided at the tips of the tip guide members 52a to 52z. The guide members 54a to 54z with tip holes guide the yarn paths of the yarns 46a to 46z wound around the warping drum 14 by the yarn guide units 44a to 44z. By rotating the yarn guide units 44a to 44z, the yarns 46a to 46z drawn from the yarn feeding bobbins 42a to 42z can be wound around the warping drum 14, and the yarn guide units 44a to 44z are stopped. As a result, the winding of the yarns 46a to 46z on the warping drum 14 can be stopped.

  The tip guide members 52a to 52z rotate around the warping drum 14 at a position indicated by a solid line in FIG. 3 during warping, that is, during winding of the yarn 46a, and in FIG. It is preferable to adopt a configuration that allows movement by driving means such as a rotary air cylinder or a rotary solenoid motor so as to retreat to the position indicated by the dotted line. With this configuration, when the warp is performed using the yarn guide unit 44d positioned on the outer side and the yarn guide units 44a to 44c positioned on the inner side are stopped, the yarn guide units 44a to 44c that are stopped are stopped. By waiting at a position off the yarn path of the yarn 46d warped by the yarn guide unit 44d, a smooth warping operation can be performed.

  If the sample warping machine with the series yarn guide mechanism of the present invention is used, both the single warping and the simultaneous warping of multiples are performed by the pattern data (conventional array design) input before the start of the warping work. It becomes possible.

  In the case of multiple warping simultaneously, as shown in FIG. 2, the warp necessary for warping is obtained by warping while developing the yarn guide units 44a to 44d (in the case of four warps) radially at equal intervals. Can be taken. On the other hand, in order to use two double yarns or three double yarns used for feather double fabric and towel fabric, two rows of yarn guide units 44a and 44b and three rows of yarn guide units 44a to 44c are arranged. It becomes possible to implement freely by arranging.

  The yarn selection of the sample warper with the series yarn guide mechanism of the present invention may be performed by rotating the yarn guide units 44a to 44z during the aging time and stopping the yarn guide units 44a to 44z during the pause. Using the yarn selection device that was essential for the sample warper, it is no longer necessary to remove the yarn from the yarn guide and supply the yarn to the yarn guide between the yarn guide and the yarn selection device. There is no trouble that occurred with this.

  The stop position when the yarn guide units 44a to 44z are stopped is preferably between the cut lower bar 18a and the cut upper bar 18h, as indicated by a dotted line in FIG. 2 (only 44a is shown in FIG. 2). is there. This is because the cut traverse bar 18a is a traverse bar that forms a position for cutting the warped yarn, and the cut traverse bar 18h is provided on the surface of the warping drum 14 with the opposite end of the cut yarn. This is because it is a weaving bar that is fixed to the warping drum 14 by a clip device (not shown) and distinguishes between the first yarn and the final yarn when the yarn on the warping drum 14 is rewound around the warp beam.
