Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a drawing device, and more particularly to a drawing device that can pass warp threads through a reed and a heddle with one device using an air jet.

In particular, the present invention can be embodied in a device that enlarges the gap between the reed wings by means of an air jet from a nozzle located close to and opposite to the gap between the reed wings, and inserts the thread between the reed wings.

(B) Prior Art As a warp preparation process in weaving work, there is a work in which the warp threads are passed through the gaps between the reed blades of a reed and into the heald holes of a heddle. By the way, inserting the warp threads into the gaps between the reed feathers and inserting the warp threads into the heald holes are a series of operations.
Conventionally, each of these operations has been performed using separate devices, which has resulted in the problems that the device for performing the thread preparation process has become complicated and large, and the work efficiency has deteriorated.
In addition, there is a problem that the warp threads may be cut because the warp threads sucked into the ventilate are pulled out by the heddles.

(c) Problems to be solved by the invention The problem to be solved by the invention is to improve work efficiency by threading the warp threads through the heddles and reeds at once using an air jet. The object of the present invention is to simplify transportation, eliminate thread breakage, and simplify and downsize the device.

(d) Means for solving the problem In order to solve the above problem, the present invention attaches a heald holder to the outer periphery of an intermittently rotating turntable to hold the heald at a position away from the heald hole, and A nozzle block is provided in the center, and the nozzle block includes a nozzle extending toward the gap between the reed blades and a heald hole of the heald that communicates with the nozzle and is held by the heald holder when the turntable is stopped intermittently. A thread introduction hole is formed in communication with the air introduction hole, and the nozzle is connected to the air introduction port, and a heald supply device is provided at the periphery of the turntable to supply the healds one by one to the heald holder, and a heald feeder is provided adjacent to the thread introduction hole. A warp feeding device that sends the warp near the heald hole of a stopped heald and a heald transfer device that transfers the heald held by the heald holder to the heald rod are provided spaced apart in the circumferential direction of the turntable. has been done.

(E) Operation In the above configuration, a reed is sent near the tip of the nozzle, and the nozzle is stopped in a state where it is located in the gap between the reed blades. When the heald holder comes to the position of the heald supply device, the heald holder is supplied with healds from the heald supply device. Then, the turntable rotates intermittently while the heald holder holds the heald, and the heald is sent to a position where the heald hole communicates with the thread introduction hole. Thereafter, the warp threads are sent near the heald holes by the warp thread feeding device, and pressurized air is sent into the nozzle from the air inlet.
The warp threads are then blown into the nozzle through the heddle holes and the thread introduction holes, and from there into the gaps between the reed blades. After the warp threads are threaded, the turntable is rotated intermittently, and the healds are transferred to the heald rod by the heald transfer device.

(F) Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, the entire drawing device 1 of this embodiment is schematically shown. In the figure, 2 is a turntable that is intermittently rotated by a predetermined angle (60 degrees in this example) by a known intermittent drive mechanism, 3 is a nozzle block provided in the center of the turntable, and 4 is a periphery of the turntable. A plurality of (six in this embodiment) heald holders are provided at equal intervals in the section. In addition, 5 is a heald supply device, 6
7 is a warp feeding device, and 7 is a heald transfer device, which are arranged as shown.

As shown in FIG. 3, a pair of turntables 2 are fixed to a drive shaft 21 at an interval corresponding to the length of the heald, separated in the axial direction. The drive shaft 21 is intermittently rotated by an intermittent drive mechanism 22.

The nozzle block 3 has a nozzle 31 extending toward one end (lower end in FIG. 1), a thread introduction hole 32 that communicates with the nozzle 31 and opens at the other end (upper end in the figure) of the nozzle block, and An air inlet 33 communicating with the upper end is formed. The open end of the thread introduction hole 32 serves as an intermittent stopping position for the heald held by the heald holder. Further, an air supply source is connected to the air introduction port 33 so that pressurized air can be supplied to the air introduction port.
In Fig. 1, the left side portion 35 of the nozzle 31 and the thread introduction hole 32 is a cover that can be opened and closed by a known method, and when opened, the warp threads passed through the nozzle and the thread introduction hole are passed through the healds and reeds. It is designed so that it can be discharged from there as it is.

In this embodiment, the heald holder 4 is made of a permanent magnet so that it can be held by magnetic force, but it may also have a structure in which it is attracted and held by vacuum.

As shown in FIG. 4, the heald supply device 5 intermittently stops a plurality of pairs of guide rails 51 that pass through a pair of upper and lower guide holes b of a heald a, and a heald a that is held and guided by the guide rails 51. It has a feed rod 52 that feeds the heald holder 4 toward the heald holder 4 on the turntable. The feed rod 52 is adapted to be operated by a cylinder 53.

The warp feeding device 6 includes a guide rod 61 that extends substantially parallel to the direction in which the nozzle extends, a slider 62 that is movably supported by the guide rod 61, and a slider 62 that is attached to the slider 62 and moves the warp e to the open end of the thread introduction hole 32. It has a guide member 63 of a known structure that guides the heald hole c of the heald a stopped adjacent thereto. Slider 62 is cylinder 6
4 along the guide rod 61. Note that 65 is a commercially available leeching machine for sorting the warp yarns, and is designed to operate in conjunction with the slider 62. Further, since the method for guiding the warp threads by the guide member is the same as the conventional method, a detailed explanation thereof will be omitted. The heddle transfer device 7 includes a guide rail 71 extending substantially perpendicular to the guide rod 61 of the warp feeding device 6, a slider 72 movably supported by the guide rail 71, and a heald movement selection robot 73 mounted on the slider 72. It is equipped with The heald movement selection robot 73 is equipped with a gripper 74 having a known structure and movable in a direction perpendicular to the guide rail 71.

This heald transfer device 7 is operated by a plurality of healds arranged parallel to a guide rail 71 after the heald is gripped by a gripper 74 of a heald movement selection robot 73 when the heald a held by the heald holder 4 is at the take-out position E. The heald rod is carried to the position of the selected heald rod among the heald rods 76, and the heald rod is transferred to the heald rod so that the heald rod 76 enters the guide hole b.

In the drawing device having the above configuration, the reed g is positioned below the open end of the nozzle 31 so as to be substantially parallel to the guide rail 51 of the heald supply device 5, as shown in FIG. The pitch is intermittently sent one pitch at a time between the reed feathers h. The opening end of the nozzle 31 is located at a distance i between the reed blades.

Under such conditions, the heald supply device 5 supplies the healds a one by one to the heald holder 4 attached to the turntable 2, and the heald holder 4 holds the healds a parallel to the rotation axis. When the turntable rotates intermittently and the heald a held by the heald holder 4 comes to position D, the warp e also moves to the warp feeding device 6.
It is sent to the vicinity of heald hole C of heald a which is selected by and stopped at position D. Thereafter, when pressurized air is supplied to the air introduction port 33, the warp threads e are sucked into the nozzle 31 through the heald hole c and the thread introduction hole 32 by the action of negative pressure generated in the thread introduction hole 32.
Furthermore, it is blown into the gap i. As a result, the warp threads e can be passed through the heald holes c of the heald a and the gaps i of the reed g at the same time.

Cover 35 of nozzle block 3 after threading the warp
opens and the warp threads are removed from the nozzle 31 and the thread introduction hole 32, and the turntable 2
is rotated intermittently by one pitch, and the heald a, through which the warp threads have been passed, is sent to position E. At this time, the warp threads e are removed from the nozzle 31 and the thread introduction hole 32. The heald a sent to the position E is delivered to the designated heald rod 76 by the heald delivery device 7. The reed is then advanced one pitch, and the next action is repeated.

(g) Effects According to the present invention, the following effects can be achieved.

Since the warp threads can be threaded through the reed and heddles at the same time using one device, the device can be simplified and work efficiency can be improved.

Since the warp threads can be threaded through the reed and heddles at once, there is no waste and no thread breakage occurs within the thread introduction holes.

Since the nozzle for threading the warp threads is dispensed with a single nozzle,
Air consumption can be reduced.
