Definitions

  • the present invention relates to a warp rearrangement method and device as a weaving preparatory operation performed before weaving a fabric using a weaving machine.
  • Warp rearrangement is an operation performed to arrange warps from two or more different warp sheets into a single warp sheet with a desired order.
  • the warps of the different warp sheets can have different thicknesses, colors, or be made from different materials, such as natural fibers and synthetic fibers.
  • Garakumi in Japanese.
  • Conventional warp rearrangement is performed by referring to a predetermined order table while manually aligning warps of different material, color, thickness, and the like in a desired order in a single-layer sheet shape.
  • the warps rearranged in this manner are then passed one at a time through the dropper, the heddles, and the reed, before being dressed onto the loom.
  • a plurality of warp beams are each wound with a different warp sheet.
  • the warp sheets are formed from a plurality of warps aligned in a single-layer sheet shape.
  • the warp sheets are drawn from the plurality of warp beams and held together in a multi-layer condition at a warp-beam side holding position and separately at a thread tip side of each of the warp sheets. This supports the warp sheets separated and under tension in a radial configuration centered on the warp-beam side holding position.
  • warps are separated one at a time from optionally selected ones of the held warp sheets, caught at a thread end thereof, and transported to a leasing position.
  • the transport is performed three-dimensionally centered on the warp-beam-side holding position, without changing thread length between the warp-beam-side holding position and the caught thread end. Then the transported warps are leased at the leasing position and the thread ends of the leased warps are fixed together.
  • a warp rearrangement device includes a plurality of warp beams, a multi-layer thread tension mechanism, a thread separation mechanism, a thread end transport mechanism, a leasing mechanism, and a thread end fixing mechanism.
  • Each of the warp beams is wound with a different warp sheet formed from a plurality of warps aligned in a single-layer sheet shape.
  • the multi-layer thread tension mechanism includes an intermediate holding portion and a plurality of tip holding portions.
  • the intermediate holding portion holds the warp sheets from the different warp beams together in a multi-layer condition at a warp-beam side holding position.
  • the tip holding portions each hold a thread tip side of a different one of the holding sheets. Together, the intermediate holding portion and the tip holding portions support the holding sheets separated and under tension in a radial configuration that is centered on the warp-beam side holding position of the intermediate holding portion.
  • the thread separation mechanism separates the warps one at a time from the supported warp sheets.
  • the warps are separated in a predetermined order from the warp sheets, depending on the desired rearrangement.
  • the thread end transport mechanism includes a thread-end holding portion that catches a thread end of each separated warp.
  • the thread-end holding portion transports the caught warp three-dimensionally, centered on the warp-beam-side holding position, without changing thread length between the warp-beam-side holding position and the thread-end holding portion.
  • the leasing mechanism leases the transported warps and the thread end fixing mechanism fixes the thread end of leased warps.
  • the warps drawn out from the warp beams can be reliably rearranged and maintained in a predetermined order into a single-layer sheet.
  • Subsequent preparations for weaving such as passing the warps one at a time through the dropper, the heddles, and the reed, can be performed smoothly.
  • warp rearrangement can be automatically performed, wherein the warps of the warp beams can be automatically rearranged in a predetermined order and fixed in place so that the warps from one of the warp beams are aligned with warps from the other warp beam or beams. This reduces the labor burden on the operator and greatly enhances warp rearrangement operations.
  • the warp rearrangement device 1 includes a multi-layer thread tension mechanism 20, a thread separation mechanism 30, a thread-end transport mechanism 40, a leasing mechanism 50, and a thread-end fixing mechanism 60.
  • the warp rearrangement device also includes a follower movement mechanism 70 as shown in Fig. 2 and thread-separator movement mechanisms 81, 82 and cutter portions 91, 94 as shown in Fig. 4.
  • the warp rearrangement device 1 is mounted with two warp beams 10, 11 wound with warp sheets 12, 13, respectively.
  • the warp sheets 12, 13 are formed by aligning a plurality of warps 15 into a single-layer sheet shape.
  • the warps 15 of the different warp sheets 12, 13 can be of the same or different materials, and have the same or different color or thickness.
  • the resultant warp sheets 12, 13 are then wound onto the warp beams 10, 11, respectively.
  • the multi-layer thread tension mechanism 20 includes an intermediate holding portion 21 and upper and lower tip holding portions 22, 23.
  • the intermediate holding portion 21 holds both of the two warp sheets 12, 13 drawn from the two warp beams 10, 11 at the same holding position 24.
  • the two tip holding portions 22, 23 separately hold the warp sheets 12, 13 at tip holding positions 25, 26 to support and apply tension to the warp sheets 12, 13.
  • the multi-layer thread tension mechanism 20 also includes tip holder guides 27, 28 formed with arc shaped slots 27a, 28a, respectively.
  • the tip holding portions 22, 23 are slidably mounted in the slots 27a, 28a.
  • the slot 28a is formed with an arc shape that follows an imaginary arc 16a of an imaginary circle with a diameter 16b centered on the holding position 24 of the intermediate holding portion 21.
  • the slot 27a is also shaped to follow the imaginary arc 16a.
  • an adjustment mechanism is provided for fixing position of the tip holding portions 22, 23 at optional positions in the slots 27a, 28a. With this configuration, the tip holding portions 22, 23 can be separated vertically to support the warp sheets 12, 13 to radiate from the holding position 24 of the intermediate holding portion 21.
  • the thread separation mechanism 30 is for separating an edge thread 15a from a selected one of the upper and lower sheets 12, 13 and moving the edge thread 15a to the thread-end transport mechanism 40.
  • the thread separation mechanism 30 includes two thread separation blocks 31, 32.
  • the thread separation block 31 includes leasing strings 31a, 31b for leasing the warps 15 of the warp sheet 12 and the thread separation block 32 includes leasing strings 32a, 32b for leasing the warps 15 of the warp sheet 13.
  • the thread separation blocks 31, 32 also include well-known thread separation configuration for separating an edge warp 15a one at a time from the warp sheets 12, 13 in cooperation with the leasing strings 31a, 31b, 32a, and 32b and pulling a portion TP of the separated thread from, as shown in Fig. 4, alignment with the sheet edges 12a, 13a to thread-end catching positions 40a, 40b of the thread-end transport mechanism 40 (to be described later).
  • a computer is provided with a thread selection program for controlling selection of warp sheets 12, 13. The thread selection program selects one of the warp sheets 12, 13 and drives the corresponding thread separation block 31, 32 to separate an edge warp 15a from the selected warp sheet 12, 13.
  • the thread separation mechanism 31 uses the leasing strings 31a, 31b, 32a, 32b to separate warps 15 from the warp sheets 12, 13, any thread separation mechanism that separates one thread at a time from the warp sheets could be used, such as a thread separation mechanism that does not require the warps to be in a leased condition.
  • the follower mechanism 70 follows changes in the position of the sheet edges 12a, 13a caused by separating and transporting edge warp 15a from the warp sheets 12, 13.
  • the follower mechanism 70 moves the thread separation blocks 31, 32, the thread-end transport mechanism 40, the leasing mechanism 50, and the thread-end fixing mechanism 60 accordingly.
  • the follower mechanism 70 includes a movement frame 71, a rack 72 attached to the body of the warp rearrangement device, a pinion 73 attached to the movement frame 71, and a transport motor 74 for rotating the pinion 73.
  • the plurality of thread separation blocks 31, 32, which correspond to the warp sheets 12, 13, respectively, and the thread-end transport mechanism 40 are attached to the movement frame 71.
  • a thread detection sensor for detecting the sheet edges 12a, 13a of the warp sheets 12, 13 is also attached to the movement frame 71.
  • the transport motor 74 rotates the pinion 73 a predetermined amount in order to move the movement frame 71 to follow movement of the edges 12a, 13a in synchronization with detection of the edges 12a, 13a by the thread detection sensor.
  • the thread-separator movement mechanisms 81, 82 each include a control motor for driving the upper and lower thread separation blocks 31, 32 to move independently from each other forward and rearward in between sheet edges 12a, 13a of the sheets 12, 13 and a position that corresponds to thread-end catching positions 40a, 40b of the thread-end transport mechanism 40 (to be described later).
  • Each cutting portion 91 includes a cutter 93 and a cutting member 92.
  • the cutting member 92 operates in cooperation with the cutter 93 to cut warps interposed therebetween.
  • the computer controls the cutting portions 91, 94 to operate differently when thread separation is performed in the normal fashion and when the thread separation blocks 31, 32 are moved independently from each other toward and away from the warp sheets 12, 13. That is, during a normal separation operation, after one of the thread separation blocks (31 for example) separates an edge warp 15a from the corresponding warp sheet (12 in this example), then the follower movement mechanism 70 moves both of the thread separation blocks 31, 32, and consequentially both of the cutting portions 91, 94, to the edges 12a, 13a of the warp sheets 12, 13 without the other warp sheet (13 in this example) interfering with forward movement of the other thread separation block (32 in this example).
  • the sheet edge of that sheet will be positioned much further forward than the edge of the other sheet.
  • the sheet edge 12a will be positioned much further forward than the edge 13a of the other sheet 13. If the edge 13a of the sheet 13 interferes with forward movement of the thread separation block 32, the follower movement mechanism 70 cannot move the thread separation block 31, and consequently cannot move the cutting portion 91, to the sheet edge 12a, so no further threads can be separated from the sheet 12.
  • the thread-separator movement mechanisms 81, 82 operate independently to move only one of the thread separation blocks 31, 32 so that threads can still be separated from the sheets 12, 13. This will be referred to as an independent movement operation, hereinafter.
  • the upper thread warp separation block 31 separates a single edge warp 15a from the upper warp sheet 12 and the thread separation configuration (not shown) of the upper thread warp separation block 31 pulls the edge warp 15a toward the upper separation block 31.
  • the portion TP of the thread 15a moves from alignment with the edge 12a of the sheet 12 as shown in Fig. 3 to the thread-end catching position 40a as shown in Fig. 4.
  • the edge warp 15a is positioned at the opening between the cutting member 92 and the cutter 93 of the cutting portion 91.
  • a thread-end catching portion 46 of the thread-end transport mechanism 40 catches hold of the thread portion TP of the thread at the thread-end catching position 40a as shown in Figs. 5 and 6, then as shown in Fig. 7 the cutter 93 of the cutter portion 91 moves downward toward the cutting member 92 to cut the end-side of the edge warp 15a, and is then driven to immediately rise upward again.
  • the thread separation mechanism 31 is moved separately from the other thread separation mechanism 32.
  • the thread-separator movement mechanism 81 moves the upper thread separation block 31 and the upper cutting portion 91 forward from the position shown in Fig. 10 to a position as near to the sheet edge 12a as possible as shown in Fig. 11.
  • the thread separation configuration (not shown) of the upper thread separation mechanism 31 pulls a single edge warp 15a from the upper warp sheet 12 to the location of the cutter 93 as shown in Fig. 12.
  • the cutter 93 of the cutting portion 91 lowers to cut the separated thread 15a.
  • the cutter 93 does not immediately rise upward, but remains in its lowered position to hold the tip of the cut edge warp 15a between the cutter 93 and the cutting member 92.
  • the thread-separator movement mechanism 81 moves the upper thread separation mechanism 31 and the upper cutting portion 91 rearward to pull the warp held by the cutter 93 to the thread-end catching position 40a of the thread-end catching portion 46.
  • the cutter 93 of the cutting portion 91 rises up to release the tip of the edge warp 15a.
  • the thread-end transport mechanism 40 is for grasping the thread position TP of a separated edge warp 15a, whether separated by the normal thread separation operation or the independent movement operation, at the thread-end catching position 40a and then transporting the single edge warp 15a three-dimensionally centered on the holding position 24 of the intermediate holding portion 21, without changing the distance between the holding position 24 and where the thread-end transport mechanism 40 holds the thread 15a.
  • the thread-end transport mechanism 40 includes endless rotating belts 41a, 41b, a thread-end catching unit 45, and a guide groove portion 47.
  • the guide groove portion 47 is disposed between the two rotating belts 41a, 41b and includes two flange portions 47a, 47c that define therebetween a groove 47b with an arc shape as viewed in Fig. 2.
  • the thread-end catching unit 45 includes attachments 42a, 42b, two slide shafts 43a, 43b, an attachment body 44, a thread-end catching portion 46, and an operation mechanism (not shown).
  • the attachments 42a, 42b are attached to the rotating belts 41a, 41b.
  • the slide shafts 43a, 43b are supported between the attachments 42a, 42b.
  • the attachment body 44 is mounted on the slide shafts 43a, 43b slidable in the horizontal direction.
  • the attachment body 44 includes a roller that fits in the groove 47b.
  • the attachment body 44 slides horizontally on the slide shafts 43a, 43b in association with the arc-shape of the groove 47b.
  • the attachment body 44 is adapted for attaching the thread-end catching portion 46 thereto.
  • the thread-end catching portion 46 includes a fixed holding cylinder 46a and a holding body 46b.
  • the holding member 46b is capable of protruding from and retracting back toward the holding cylinder 46a and so can hold the edge warp 15a between the end surface of the holding cylinder 46a by retracting back and then releasing the tip of the edge warp 15a by protruding outward.
  • the operation mechanism includes a motor (not shown) and an air compression cylinder (not shown).
  • the motor drives rotational movement of the rotating belts 41a, 41b.
  • the air compression cylinder operates to protrude and retract the holding body 46b from and toward the holding cylinder 46a at the thread-end catching position 40a to hold and release the edge warp 15a.
  • a plurality of thread-end catching units are provided with the same configuration as the thread-end catching unit 45 and are attached to the rotating belts 41a, 41b separated by a predetermined spacing.
  • the transport mechanism 40 transports the cut edge warp 15a first substantially perpendicular to, and then substantially parallel to, planes defined by the warp sheets 12, 13 supported by the thread tension mechanism 20. In other words, the transport mechanism 40 transports the thread in a three-dimensional movement. Because the roller of the attachment body 44 follows the arc shape of the groove 47b and can shift leftward and rightward on the slide shafts 43a, 43b, the transport mechanism 40 can transport the edge warp 15a three-dimensionally centered on the holding position 24 of the intermediate holding portion 21 without any change in the thread length between the holding position 24 and the thread position TP where the thread-end catching position 40a holds the thread.
  • the leasing mechanism 50 includes two leasing string holding pegs 51a, 51b. Each holding peg 51a, 51b has a wing formed with a hole. A leasing string 52, 52 is tied to each of the wings through the corresponding hole. The leasing strings 52, 52 are supported with tension by the pegs 51a, 51b and aligned in a direction that is perpendicular to the tension direction of the warps 15 transported one at a time by the thread-end transport mechanism 40.
  • Vertical movement mechanism moves the holding pegs 51a, 51b vertically, which is a direction perpendicular to the tension direction of the edge warp 15a, in alternation so that when the holding peg 51a is in an upper position, the other holding peg 51b is in a lowered position, and vice versa.
  • the thread-end catching portion 46 of the thread-end transport mechanism 40 brings a single edge warp 15a to the leasing mechanism 50, one of the pegs 51a, 51b moves up and the other moves down to perform a leasing operation, wherein the leasing strings 52, 52 hold the order of the warps 15 aligned in a single-layer sheet shape.
  • the thread-end fixing mechanism 60 sandwiches the ends of the warps 15, which are transported one after the other by the thread-end transport mechanism 40 as shown in Fig. 9, between two strips of adhesive tape 61, 62 to fix the ends of the warps 15 in place and form a single layer sheet as shown in Fig. 19.
  • the two warp beams 10, 11 are prepared, wound with the warp sheets 12, 13, respectively, which are formed from a plurality of warps 15 aligned in a single-layer sheet shape.
  • the two warp sheets 12, 13 are drawn from the warp beams 10, 11 and passed between the intermediate holding portions 21 to the tip holding portions 22, 23 as two separate layers.
  • the intermediate holding portion 21 holds the portion of the two warp sheets 12, 13 near the warp beams 10, 11 and the mutually separated tip holding portions 22, 23 support the two warp sheets 12, 13 to radiate in different directions applied with tension.
  • the thread separation blocks 31, 32 separate the warps 15 one at a time from selected ones of the two warp sheets 12, 13 using the normal thread separation operation that was described with reference to Figs. 3 to 8 or the independent movement operation that was described with reference to Figs. 10 to 18.
  • the thread-end catching portion 46 of the thread-end transport mechanism 40 catches the thread position TP of the separated single edge warp 15a at the thread-end catching position 40a.
  • the thread-end transport mechanism 40 transports the edge warp 15a three dimensionally without changing the thread length between the holding position 24 (which is near the warp beams 10, 11) and the thread position TP.
  • the leasing mechanism 50 performs a leasing operation on the warps 15 that were transported one at a time by the thread-end transport mechanism 40.
  • the thread-end fixing mechanism 60 fixes the ends of the warps 15 that were transported one at a time so that the warps 15 can be fixedly aligned in a single-layer sheet 100 shown in Fig. 19. Accordingly, by repeatedly performing this process, the warps 15 drawn out from the warp beams 10, 11 can be reliably rearranged and maintained in a predetermined order into the single-layer sheet 100. Subsequent preparations for weaving, such as passing the warps one at a time through the dropper, the heddles, and the reed, can be performed smoothly.
  • warp rearrangement can be automatically performed, wherein the warps 15 of the warp beams 10, 11 can be automatically rearranged in a predetermined order and fixed in place so that the warps 15 from the warp beam 10 are aligned with warps 15 from the other warp beam 11. This reduces the labor burden on the operator and greatly enhances warp rearrangement operations.
  • one of the thread separation blocks 31, 32 selectively separates a single warp 15a from the corresponding warp sheet 12 and also pulls the single edge warp 15a, at the thread portion TP thereof between the holding position 24 (near warp beams 10) and the thread-tip side of the thread-end holding position 25, to the thread-end catching position 40a.
  • the thread-end catching portion 46 catches the edge warp 15a
  • the corresponding cutting portion 91 cuts the end of the edge warp 15a. Therefore, the separated edge warp 15a can be reliably transferred to the thread-end transport mechanism 40.
  • one of the thread separation blocks 31, 32 for example the thread separation block 31, separates the single edge warp 15a selectively from the corresponding warp sheet 12 and pulls the edge warp 15a to the cutting portion 91.
  • the cutter 93 is driven to move downward and remain there, thereby simultaneously cutting the edge warp 15a and grabbing the end of the edge warp 15a.
  • the thread-separator movement mechanism 81 moves the thread separation block 31 and the cutting portion 91 rearward to pull the edge warp 15a to the thread-end catching position 40a.
  • the cutter portion 93 releases the end of the edge warp 15a. As a result, the edge warp 15a can be reliably transferred to the thread-end transport mechanism 40.
  • the positions of the two tip holding portions 22, 23 of the multi-layer thread tension mechanism 20 can be adjusted by moving the tip holding portions 22, 23 along an imaginary arc of an imaginary circle centered on the holding position 24 of the intermediate holding portion 21 and then fixing the tip holding portions 22, 23 in place, the warp sheets 12, 13 can be supported with tension in a radial arrangement without changing the thread length between the holding position 24 and the tip holding positions 25, 26 of the tip holding portions 22, 23.
  • the position of the threads 15 relative to the thread separation blocks 31, 32 can be that much more easily adjusted. Also, because a separate thread separation mechanism 31, 32 is provided for each of the warp sheets 12, 13, the relative positions between the warp sheets 12, 13 and the thread separation blocks 31, 32 can be easily adjusted and the warps 15 can be smoothly separated from the warp sheets 12, 13.
  • the follower movement mechanism 70 moves the thread separation blocks 31, 32, the thread-end transport mechanism 40, the leasing mechanism 50, and the thread-end fixing mechanism 60 to follow changes that occur in position of the sheet edges 12a, 13a of the warp sheets 12, 13 as warps 15 are separated from the warp sheets 12, 13. Because the follower movement mechanism 70 is provided, the relative positions of the warp sheets 12, 13, the thread separation blocks 31, 32, the thread-end transport mechanism 40, the leasing mechanism 50, and the thread-end fixing mechanism 60 can be properly maintained with changes associated with warps 15 being separated from the warp sheets 12, 13. The configuration is much simpler than if the warp beams 10, 11 and the multi-layer thread tension mechanism 20 where moved to follow changes associated with the warps 15 being separated from the warp sheets 12, 13. The warp sheets 12, 13 that have been subjected to leasing process as described above, can be smoothly moved to subsequent processes for preparing to dress the loom so that operations are that much easier.
  • the thread-separator movement mechanisms 81, 82 are provided to move the thread separation blocks 31, 32 reciprocally in an independent manner between the sheet edges 12a, 13a and the thread-end catching position 40a of the thread-end catching portion 46, the thread separation blocks 31, 32 can be moved reciprocally in an independent manner to the optimum thread separation position, which depends on the position of the sheet edges 12a, 13a of the warp sheets 12, 13.

  • a first thread separation mechanism separates many threads one after the other from the same warp sheet, while the other thread separation mechanism remains inactive.
  • the sheet edge of the other warp sheet will be much closer to the thread separation mechanisms than the sheet edge of the first warp sheet. If the thread separation mechanisms are moved integrally, then the other sheet separation mechanism will abut against its warp sheet, thereby preventing the first thread separation mechanism from moving close enough to the warp sheet to separate any more threads.
  • the positions of the sheet edges 12a, 13a can be easily placed out of alignment, for example, when the threads of the warp sheets 12, 13 are loosely arranged (not densely grouped together).
  • the thread-separator movement mechanisms 81, 82 can move the thread separation blocks 31, 32 forward and rearward independently from each other to the optimum position for thread separation in accordance with the sheet edges 12a, 13a of the warp sheets 12, 13.
