- Also, there has been known an electronically controlled sample warper which can warp a plurality of yarns concurrently, wherein time loss required for the yarn exchanging is cancelled and a plurality of yarns can concurrently be wound on a warper drum by using a rotary creel as well as omitting the yarn exchanging step, and further a period of time required for the warping work can be reduced (see Japanese Patent No. 1767706, U.S. Pat. No. 4,972,662, and EP No. 0375480).
- Since the fixed creel has a plurality of bobbins around which different kinds and/or the same kind of yarns (mainly different kinds of yarns) are wound and it is used for warping the yarns one by one, it is advantageously possible to perform pattern warping, but the yarns are wound on a warper drum one by one, so it takes disadvantageously much time to perform warping work correspondingly. Meanwhile, the rotary creel has a plurality of bobbins around which the same kind and/or different kinds of yarns are wound, and it is used for the plain warping (for example, only red color yarns), and the limited pattern warping, such as one to one warping (for example, repetition of a yarn of red color and a yarn of white color, or repetition of a yarn of S twist and a yarn of Z twist), two to two warping (for example, repetition of two yarns of red color and two yarns of white color, or repetition of two yarns of S twist and two yarns of Z twist). With the rotary creel, it is disadvantageously impossible to perform pattern warping other than the limited pattern warping, but it is advantageously possible to wind a plurality of yarns concurrently on the warper drum so that the warping time is reduced largely.

- The present invention will hereinafter be described in connection with embodiments with reference to the accompanying drawings.
- In FIG. 1, an electronically controlled sample warper W of the present invention comprises: a warper drum A; a plurality of yarn introduction means6 a to 6 d (four in the illustrated embodiment) each mounted to a side surface of the warper drum for winding
yarns 22 a to 22 e on the warper drum A; and a plurality ofyarn selection guides 27 arranged in one end portion of a base for supporting the warper drum A in correspondence to the yarn introduction means 6 a to 6 d, each theyarn selection guide 27 being pivotally moved to protrude to a yarn exchanging position when theyarns 22 a to 22 e are exchanged and pivotally moved to retract to a standby position when theyarns 22 a to 22 e are stored, wherein yarns 22 a to 22 e are passed between the yarn introduction means 6 a to 6 d and theyarn selection guides 27, so that theyarns 22 a to 22 e are exchanged according to the preset yarn order to be wound on the warper drum A. The basic structure and operation of the electronically controlled sample warper W are well-known from the above-mentioned patent publications, and detailed description thereof will be omitted. - In the electronically controlled sample warper W of the present invention, there are positioned adjacent corresponding ones of the plurality of yarn selection guides27 a rotary creel F supporting a plurality of
bobbins 100 a to 100 e (five in the illustrated embodiment) around which different kinds and/or the same kind ofyarns 22 a to 22 e are wound, and abobbin station 102 supporting a plurality ofbobbins 100 a to 100 e around which different kinds and/or the same kind of yarns are wound in a standby state. - The characteristic structure of the present invention resides in that the
bobbins 100 a to 100 e can detachably be supported by the rotary creel F and thebobbin station 102, respectively, and thebobbins 100 a to 100 e can be passed freely between the rotary creel F and thebobbin station 102. - In FIG. 1,
reference numerals 104 a to 104 e - denote bobbin bodies, which are composed of
bobbin frames 106 a to 106 e and thebobbins 100 a to 100 e attachable thereto, thereby the attaching and detaching operation of thebobbins 100 a to 100 e being easy. The basic structure of the rotary creel F is not changed from a conventional one. However, the rotary creel F is provided at its front portion with a plurality of bobbin receiving recesses 108 (four in the illustrated embodiment), into which thebobbin bodies 104 a to 104 e are detachably inserted. - It is enough for the
above bobbin station 102 to retain the plurality ofbobbin bodies 104 a to 104 e detachably in a standby state, and there are no need any specific constructions therefor. In the embodiment shown in FIG. 1, however, a plurality of bobbin receiving portions 112 (four in the illustrated embodiment) are formed on tworail members bobbin bodies 104 a to 104 e are detachably set in thebobbin receiving portions 112. - The bobbin station102 (or the
rail members bobbin bodies 104 a to 104 e are easily passed between the rotary creel F and the bobbin receivingrecesses 108. Also, it is preferable that thebobbin bodies 104 a to 104 e are automatically passed by a known robot hand or the like according to the preset pattern data (yarn order). - As the above-mentioned
yarn selection guides 27, such conventional ones as shown in FIG. 2 can be used. In FIG. 2, the plurality ofyarn selection guides 27 selectivelyguide yarns 22 a to 22 e according to the instructions from a program setting unit. Theyarn selection guides 27 are attached one to eachrotary solenoid 29. When the individualrotary solenoid 29 is energized, the correspondingyarn selection guide 27 is pivotally moved to advance to its operative position (yarn exchanging position) as shown with a phantom line in FIG. 3; when therotary solenoid 29 is de-energized, theyarn selection guide 27 is reversely pivotally moved to its standby position (yarn storing position) as shown with a solid line in FIG. 3. - The movements of the
yarn 22 during the yarn exchanging are shown in FIGS. 3 and 4. The distal end of the yarn introduction means 6 is inwardly bent to provide ayarn introduction part 6′ which is disposed against the front end of the outer periphery of the warper drum. Theyarn 22 k caught by theselection guide 27 initially located in its standby position (yarn storing position) assumes its yarn position 22 l as theselection guide 27 is pivotally moved to advance to its operative position(yarn exchanging position) as shown with a phantom line. From this position, the yarn 22 l is caught by theyarn introduction part 6′ and wound around the warper drum A. Theyarn selection guide 27 from which the yarn is removed is returned to the standby position (yarn storing position). 22 m designates the posture in which theyarn 22 is moved one turn, and when the yarn is not exchanged the yarn is wound around the warper drum A passing through an upper side of a guide plate S as in this posture. - When the
yarn 22 m being caught by theyarn introduction part 6′ and wound on the warper drum A is removed therefrom by ayarn removing unit 32, theyarn 22 m is pulled back to the direction of the rotary creel by a pulling-back device (not shown) and guided to a lower side of the guide plate S by aguide bar 59 a, then assuming itsposture 22 n. Theyarn selection guide 27 is pivotally moved to advance to its operative position to catch the removed yarn, and returns to the standby position (yarn storing position) with holding the yarn. The yarn in the standby position assumes itsposture 22 p in FIG. 4. - In FIGS.2 to 4, 16 designates a drum spoke of the warper drum A; 17, a conveyor belt provided on the drum spoke 16; 59, a yarn introduction cover arranged on one side of the warper drum A; 59 a, a guide bar attached on the inner surface of a lower portion of the
yarn introduction cover 59; and E, a yarn fastener mounted to a base Y. - The operation of the above-described electronically controlled sample warper W will now be described.
- Firstly, as shown in FIG. 1, the
bobbin bodies bobbin receiving recesses yarns bobbin bodies bobbin receiving portions bobbin station 102 in a standby state, andyarns - Next, when winding of four
yarns 22 a to 22 d is performed, thebobbin bodies bobbin receiving portions yarn selection guides 27 are operated so that theyarns - When winding of the
yarns bobbin bodies bobbin receiving recesses yarns yarn selection guide 27 to be stored, and thebobbin bodies bobbin receiving portions bobbin station 102. - Furthermore, when winding of a
new yarn 22 e is performed, thebobbin body 104 e is mounted to an emptybobbin receiving recess 108 of the rotary creel F, and on the other hand theyarn selection guide 27 is actuated to get the yarn introduction means 6 a to catch theyarn 22 e so that theyarn 22 e can be wound around the warper drum. - Thus, it is easy to use larger number of the
bobbins 100 a to 100 e (five in the illustrated embodiment) than the number of the yarn introduction means 6 a to 6 d (four in the illustrated embodiment) so that a wide variety of pattern warping may be unlimitedly performed. Also, the reduction of the warping time may be realized by concurrently winding a plurality of yarns on the warper drum A. - In the above-mentioned embodiment, there is described the case wherein four yarn introduction means6 a to 6 d, four
bobbin receiving recesses 108 of the rotary creel F, fourbobbin receiving portions 112 of thebobbin station 102, and fivebobbins 100 a to 100 e are used. It is possible, however, to employ eight to sixteen or more of yarn introduction means 6, eight to sixteen or more ofbobbin receiving recesses 108 of the rotary creel F, eight to twenty or more of thebobbin receiving portions 112 of thebobbin station 102, and eight to forty or more of the bobbins so as to perform ultimately a wide variety of pattern warping with various kinds of yarns. - In the above embodiment, there is explained the case wherein the yarn exchanging is performed by exchanging the bobbins of the rotary creel F for the ones of the
bobbin station 102. In the case where there is no need to use the bobbins of thebobbin station 102, it is possible, as a matter of course, to warp only the yarns wound around the bobbins supported by the rotary creel F. In this case, the yarns wound around the bobbins supported by the rotary creel are guided to the yarn introduction means 6 a to 6 d through theyarn selection guides 27. Thus, such a manner as theyarn selection guide 27 are applied to the rotary creel F is a novel inventive idea which does not reside in any conventional electronically controlled sample warpers. The structure where the yarns are guided to the yarn introduction means 6 a to 6 d through theyarn selection guides 27 may advantageously and largely save time and labor in exchanging the bobbins and so on in comparison with the conventional one where the yarns of bobbins are directly guided to the yarn introduction means 6 a to 6 d. In this embodiment, using one yarn introduction means with the rotary creel F being in an inoperative state, there is no doubt that pattern warping may be performed as in the aforementioned known fixed creel. - As described above, according to the electronically controlled sample warper of the present invention, though using the rotary creel, it is possible to employ various kinds of yarns and perform the yarn exchanging thereof unlimitedly, thus enabling various pattern warping to be freely performed with the reduced warping time.
- According to the rotary creel assembly of the present invention, it is possible to warp yarns on the warper drum with a plurality of bobbins supported by the rotary creel, set the remaining bobbins which are not used for warping yarns in the bobbin station in a standby state and perform the bobbin exchanging between the rotary creel F and the
bobbin station 102. Therefore, the rotary creel assembly is used very preferably when performing pattern warping with a number of yarns. - Also, according to the warping method of the present invention, using the above-mentioned rotary creel assembly of the present invention, it is possible to perform pattern warping with various kinds of yarns and warp concurrently a plurality of yarns with the reduced warping time.
- Obviously, various minor changes and modifications of the present invention are possible in the light of the above teaching. It is therefore to be understood that within the scope of appended claims the invention may be practiced otherwise than as specifically described.
