Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention provides a heald frame transfer means for simultaneously attaching a plurality of heald frames to a loom and removing the heald frames from the loom. The loom gear provided with this device is related to a means for guiding the installation of the heald frame to the loom, which is transferred by the device.

(Prior technology) In the work of attaching a warp beam to a loom and passing the warp threads to the weaving equipment side (tJl work is a work in progress), a new warp beam was installed in consideration of shortening the time for the above work, which would lead to improved operating efficiency of the loom. A common procedure is to insert the warp threads through a plurality of heald frames before installing them. By adopting such a work procedure, it is no longer necessary to tie the warp threads of the new warp beam example and the warp threads of the woven fabric one by one on the warp path from the warp beam on the loom to the heddle frame, and the loom process is free from work. It is possible to shorten the time required.

A device for transporting and transferring a warp beam and a heald frame through which its warp threads are inserted is disclosed, for example, in Japanese Patent Publication No. 57-53899. In this device, an arm that can be extended and contracted in the horizontal direction is supported by a pair of lifting columns, and a hook member is connected to the tip of both arms, and the upper frame of the heald frame and the upper carrier rod for tensioning the heald are connected to each other. By inserting the same latching member between them, a plurality of heald frames can be latched and suspended all at once.

(Problems to be Solved by the Invention) However, it is difficult to move the predetermined gears of the P&t, ffl i& side to the working position and stop the equipment accurately. It is not possible to accurately position the heald frame in the left-right direction with respect to the upper end insertion opening of the guiding channel-shaped guide member. Therefore, it is unavoidable that a plurality of heald frames must be manually aligned one by one with the upper end insertion opening, which is complicated, and it becomes impossible for the heald frames to be automatically installed by a device in the machine process.

Structure of the Invention (Means for Solving Problems) Therefore, in the present invention, a left and right channel-shaped guide body for guiding the vertical movement of a plurality of heald frames forming a warp shedding, or a channel-shaped guide body guided by the same guide body is provided. A machine mechanism equipped with a heald frame transfer means for simultaneously attaching and detaching a plurality of heald frames to and from a movable mounting body and supporting the heald frames so as to be movable from side to side is moved by a device to the channel-shaped guide body or An insertion guide member for a plurality of heald frames inserted from the upper end insertion port of the channel-shaped movable mounting body is installed directly above both the left and right guide members, and the heald frames are slid inward and guided to the upper end insertion port. A guide slope was formed on the insertion guide member.

(Function) In other words, even if the device does not accurately stop a predetermined loom at the rear of the loom at the working position, the loom will move upward between the pair of left and right insertion guide members installed to expand upward. When the movably arranged machine gear moves down the plurality of heald frames on the device, the plurality of heald frames supported so as to be movable left and right will collectively slide on the guide slope of one of the insertion guide members. and is guided to the upper end insertion port. Therefore, the heald frames can be smoothly inserted all at once without performing left-right alignment of the heald frames with respect to the upper end insertion opening.

(Example) Hereinafter, an example embodying the present invention will be described based on FIG. 1.2.

The levers 5 and 6 are rotatably supported by three-pronged brackets 3.4 erected on both the left and right side frames 1.2 of the loom, and are biased to rotate by springs 7 and 8.
Suspension ropes 9, 10 connected to jack lever 5.6
A channel-shaped movable mounting body 11.12 is latched and suspended from the lower end via a latching connection member 13.14. A reciprocating drive mechanism consisting of a cam 15 and a cam lever 16 that rotates in synchronization with the rotation of the machine is installed on one side of the side frame 1, and a pull-down rope 17, 18 connected to the cam lever 16 is a latching connection member. 19.20 to the lower end of the movable mounting body 11.12. Therefore, the rotation of the cam 15 is converted into vertical movement of the movable mounting body 11.degree. 12, and this vertical movement is guided by the guide bodies 21.degree. 22.

The heald frame 23 has both left and right site stays 23a.

, 12a and fixed by appropriate means, the heald frame 23 is installed and supported between the movable mounting bodies 11 and 12.

As a result, the heald frame 23 moves up and down together with the movable mounting body 11.12, and warp shedding is performed.

A guide plate 24 is provided at the upper end of the opposing surface of both the left and right brackets 3.4.
．． 25 is arranged and fixed directly above the movable mounting body 11.12 so as to cover the jack lever 5.6. The guide plates 24 and 25 have guide slopes 24a and 2 that expand upward.

The vertical surfaces 24b and 25b are connected to the mounting groove 11 of the movable mounting body 11.12.
3, 12a is set within a plane including the bottom surfaces.

Now, when replacing the heald frame in conjunction with replacing the warp beam, a warp beam transfer means is used to attach the full warp beam to the loom and remove the empty warp beam from the loom, and the warp threads of the warp beam are inserted. A device is used as a mechanism consisting of a heald frame transfer means provided with a pair of hanging members 26 and 27 capable of suspending the heald frames all at once. A plurality of latching grooves 26a and 27a, which are slightly wider than the thickness of the heald frame 23, are formed on the upper surface of the latching members 26 and 27.
It is latched and supported by fitting into 27a. The plurality of heald frames 23, which are latched and supported all at once, are attached to the movable mounting body 11, as shown by the chain lines in FIG. 1 and the solid lines in FIG.
12 and then moved downward. The plurality of movable mounting bodies 11, 12 are stopped at upper and lower surfaces where the plurality of mounted heald frames are in a leveling state.

As the loom gear is not accurately stopped at the working position, the predetermined loom gear at the rear of the loom does not accurately stop at the working position, so the moving arrangement position is changed to the mounting groove 112 of the left and right movable mounting bodies 11 and 12 when viewed in the front and back direction.

When the heald frame 23 moves further downward, the heald frame 23 receives a rightward reaction from the guide slope 25a, and the latching member 26.2 moves vertically downward.
7 and sliding to the right on the guide slope 25a.

Slide down on top. As a result, the heald frame 23 is guided between the vertical surfaces 24b and 25b of the left and right guide plates 24 and 25, and the left and right site stays 23a and 23b of the heald frame 23 are aligned with the left and right movable mounting bodies 11. 12 mounting grooves 11
2 and 12a in the vertical direction. Therefore, the complicated process of manually aligning the left and right positions of the heald frame 23 with respect to the upper end insertion openings 11b and 12b of the mounting grooves 11a and 12a becomes unnecessary.

Due to the downward movement of the latching members 26, 27, both site stays 23a of the heald frame 23 are moved as shown by the chain lines in FIG.

The lower end of 23b is the mounting groove 11a of the movable mounting body 11.12.

When the upper end insertion openings 11b and 12b of 12a are moved downward, the downward movement of the latching members 26 and 27 is temporarily stopped. If the lower ends of both site stays 23a, 23b and the upper end insertion ports 11b, 12b are misaligned in the front-back direction, the hooking members 26, 27 are moved back and forth, and both site stays 23
After aligning the lower ends of a and 23b with the upper end insertion ports 11b and 12b, if the locking members 26 and 27 are moved downward, both site stays 23a and 23b fit into the mounting grooves 112 and 12a. Thereafter, by fixing the heald frame 23 to the movable mounting body 11.12, the installation of the heald frame to the loom is completed.

In this way, both the left and right guide slopes 24 expand upwardly the insertion of a plurality of heald frames 23 into the movable mounting body 1.1.12.
By guiding the heald frames 23 through a and 25a, it is possible to smoothly insert a plurality of heald frames 23 into the loom at once, and the work time of the loom can be shortened.

Of course, the present invention is not limited to the above-mentioned embodiment, and for example, as shown in FIG. It is also possible to form a wide guide groove surface 28C and further form a regulating groove 28d that gradually narrows from the guide groove surface 28c to about 1 illa of mounting width.In this way, the heald frame 23 can be placed in the mounting groove 12a. Even if there is a shift forward or backward, the alignment will be automatically corrected.

Furthermore, the present invention can be applied to an opening forming method in which the vertical movement of the heald frame is directly guided by the guide bodies 21 and 22 in the above embodiment, and the gripping member that can grip a plurality of heald frames at once can be moved horizontally. The present invention can also be applied to transfer work using a device that is equipped with a machine.

Effects of the Invention As detailed above, in the present invention, the insertion guide member for a plurality of heald frames inserted from the upper end insertion opening of the channel-shaped guide body or the channel-shaped movable mounting body is provided directly above both the left and right guides. Since the insertion guide member is formed with a guide slope that slides the heald frame inward and guides it to the upper end insertion opening, the heald frame can be smoothly inserted without performing left-right alignment of the heald frame with respect to the upper end insertion opening. It has this excellent effect.
