JPS602200Y2 - Horizontal warp line device using dobby machine - Google Patents

Description

[Detailed description of the invention] When exchanging the warp threads of a fabric, all the heald frames 109 are aligned in one line for a separate exchange operation.

Conventionally, it has been possible to align the heald frame in the lowered position when using a dobby machine and in the raised position when using a cam machine.

This is what is called a leveling device.

However, with these leveling devices, it is impossible to align the heald frame with the negative line at the middle position of the opening (so-called mail line), so there is still inconvenience in the warp exchange operation.

Therefore, when changing the warp, each user exchanges the card 101 for the dobby machine's shell with a card for the plain weave weave, aligns the heddle frame with the mail line, and performs the warp change. I had to go through the trouble of replacing the card with a new card.

However, with recent high-speed dobbies, changing cards is not as easy as it was in the past, and many of them have an oil bath, so when changing cards, oil may scatter and stain the warp threads, or the operator may The current situation is that the oil on hands causes problems such as staining the warp threads.

In view of the above, an object of the present invention is to provide a device capable of aligning all heddle frames on a mail line by operating a handle without changing cards when changing warp threads.

The gist of the present invention is that the claw portion of the leaf spring 1 presses upward every other ball holding hook 103 of the dobby machine, and the claw portion of the leaf spring 2 presses downward every other ball holding hook 104 of the dobby machine. Leaf springs 1 are arranged in a staggered manner, respectively.
and the leaf spring 2 are fixed to the shafts 4a, 4b, and the shafts 4a, 4b are fixed.
The intermediate levers 5 and 6 fixed to the ends of the handle lever 3
They are connected so that they can rotate in opposite directions.

Then, the claws of the leaf springs 1 and 2 are shifted in a staggered manner up and down and fixed to the shafts 4a and 4b.
3.5.7. ...Press the ball holding hook 103 upwards with the claw part of the leaf spring 1, and press it 2 or 4, counting from the front.
,6. ......In order to press the lower holding hook 104 downward with the claw portion of the leaf spring 2, as shown in FIG. 1, press the first ball holding hook 103 on the leaf spring 1. Claw part 1 - Claw part 1 that presses 1.3rd ball holding hook 103 - Claw part 1 that presses 3.5th ball holding hook 103 - Claw part 1 that presses 5.7th ball holding hook 103
- 7 is formed with a gap at a predetermined interval, and the leaf spring 2 has a claw part 2.2 that presses the second lower holding hook 104 in the gap between the claw parts 1.1 and 1.3 of the leaf spring 1. , the claw parts 2 and 4 that press the fourth lower holding hook 104 are in the gap between the claw parts 1 and 3 and 1 and 5 of the leaf spring 1, and the claw parts 2 and 6 that press the sixth lower holding hook are the leaf springs. The leaf spring 1 and the leaf spring 2 are attached to the upper shaft 4a and the lower shaft 4, respectively, so that the leaf springs 1 and 2 are disposed at positions corresponding to the gaps between the claw parts 1, 5 and 1, 7 of the leaf spring 1, respectively.
It means to stick to b.

The relationship between the leaf springs 1, 2 and the upper and lower holding hooks 103, 104 is shown in FIGS. 4 and 5.

In FIG. 5, when the shafts 4a and 4b are respectively simultaneously rotated in the direction of the arrow, the upper and lower holding hooks 103, 104
hook 1 by leaf spring 1゜2 every other piece.
06, 108, and then the knives 105, 107 alternately advance to engage the hook 10.
6 and the ball holding hook 103 are engaged with each other, and the hook 108 and the lower holding hook 104 are engaged with each other.

By the way, the holding hooks and the hooks that are engaged are arranged every other sheet as described above, and as a result, when started in this state, a plain weave structure is formed in which the heald frames alternately move up and down every other sheet.

For this reason, all heald frames must be used once in one cycle.
Align in the middle of the opening.

If the dobby machine is stopped at this position, the healds will be stopped in line with the mail line, and the warp replacement work can begin.

In this case, of course, the card 101 may be left hanging, but care must be taken to ensure that the peg 102 does not give commands to the holding hooks 103, 104.

For example, remove the pegs by about 1 to 2 picks,
Alternatively, the entire cylinder may be shifted to the side so that the peg does not give commands, but this mechanism may be considered separately.

The means for pivoting the leaf springs 1, 2 are shown in FIGS. 2 and 3.

Handle lever 3, intermediate levers 5 and 6, return spring 7
is located outside the machine.

The shafts 4a and 4b are through shafts. A leaf spring 1 and a leaf spring 2 are fixed to the shaft 4a and the shaft 4b.

An intermediate lever 5 is fixed to the shaft 4a, and an intermediate lever 6 is fixed to the shaft 4b, and both levers are in contact with each other at projections 8 and 9.

A further projection 10 is provided on the intermediate lever 6 and is in contact with a handle lever 3 provided on a further shaft 13.

The intermediate levers 5 and 6 are connected by a spring 7.

When the handle lever 3 is twisted by hand in the direction of arrow A, the shafts 4a and 4b are simultaneously twisted in opposite directions via the levers 5 and 6, and the leaf springs 1 and 4 fixed to the shafts 4a and 4b are twisted simultaneously.
2 is rotated into the state shown in FIG.

The leaf spring 192 is connected to the upper and lower shafts 4av4b as described above.
Since the upper and lower holding hooks 103 and 104 are fixedly attached to the upper and lower holding hooks 103 and 104, when the handle lever 3 is twisted, the plain weave structure can be commanded to the upper and lower holding hooks 103 and 104.

In this state, the loom and dobby are operated slowly, and when the heald frame is aligned with the - line in the middle of the shedding, the operation is stopped and the warp replacement work begins.

According to the present invention, a plain weave structure can be obtained by simply rotating the handle lever 3 provided outside the machine base, and therefore all heald frames can be moved to the middle position of the opening (mail line).
The warp threads can be aligned on the - line, the warp threads can be replaced efficiently, preparatory work such as card replacement can be omitted, and oil spills can be prevented.

Also, if the handle lever 3 is fixed at the turning position, of course,
It can also be used as a plain weave weaving device.
