Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a marker mechanism in a handloom.

(Prior Art) As shown in Figure 7a, woven fabrics are generally obtained by threading a plurality of warp threads 2 vertically while passing the weft threads 3 through them.
For this purpose, as shown in FIG.
The warp threads 2 stretched between them are alternately and regularly distributed vertically to create a shuttle path S between the upper thread 2a and the lower thread 2b, and the weft thread 3 wound around the shuttle 40 is passed through it.
A mechanism is adopted in which the blade is driven in toward the front. Incidentally, it is relatively easy to alternately distribute the warp threads one by one as in the case of plain weaving, but in the case of patterned weaving, the distribution of the warp threads above and below becomes complicated. Conventionally, this has been done by using a special mount, but it is cumbersome to operate and it is not possible to perform a very complicated vertical distribution.

For this reason, hand looms have recently been proposed in which the vertical distribution of warp yarns can be easily performed using punch sheets. However, if, for example, two or three colored threads are used for the weft, and each colored thread is changed every five rows, it is difficult to determine whether or not a given colored thread has been sent, and which colored thread should be sent next. Sometimes I lose track of what I should do and when.

(Purpose of the invention) The purpose of this invention is to solve the above-mentioned drawbacks and to propose a marker mechanism for a handloom that allows the feeding of the weft to be easily confirmed.

(Structure of the invention) In order to achieve the above object, the marker mechanism according to the invention is characterized by having the following requirements.

(b) The main body of the handloom shall be provided with a support body for supporting the marker that can be moved up and down.

(b) The marker is supported by the support so that it can move up and down through the support.

(c) A punch sheet in which the drop holes for the markers are arranged vertically is provided at the lower part of the support so as to be movable in the vertical direction.

(Functions and effects of the invention) According to this invention, a punch sheet is provided at the bottom of the marker support, so when the support is moved down, the marker is supported vertically. is placed on the punch sheet, but in this case, when the marker faces a hole formed in the punch sheet, the marker falls into the hole and lowers. When facing a part other than the pit, it remains in that position. Therefore, for example, when weaving two colors of weft threads into warp threads in several rows of each color, if holes are formed in the punch sheet every several rows, the punch sheet can be advanced each time the weft thread is passed through one row. This allows you to know when the marker should fall into the hole when another weft thread should be woven. Therefore, it is very effective especially when weaving patterns. Note that the marker can have separate meanings for when it is raised and when it is lowered, so by providing marker mechanisms on both sides of the handloom body, four types of meanings can be added.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In the figure, symbol A indicates a handloom. In this handloom A, a plurality of warp threads 2 are stretched on a main body 1 in advance, and a warp thread distribution device provided approximately in the middle distributes the warp threads 2 vertically, and the distributed upper and lower threads 2a, Weft thread 3 is attached to the shed S formed between 2b
Weaving a piece of cloth by passing the weft thread 3 between the top and bottom threads 2a and 2b of the warp thread 2 by repeatedly passing it through the shuttle wrapped around it, changing the distribution of the warp thread 2 again, and passing it through the gutter from the opposite side. It is.

The warp threads 2 are stretched parallel to winding rods 1a and 1b at the front and rear portions of the main body 1.

The distribution device for vertically distributing the warp threads 2 includes a swingable support 5 which passes through a plurality of thread hooks 4 that engage the warp threads 2 and holds the warp threads 2 in a vertically movable manner at approximately the middle of the main body 1. A guide passage 7 is provided at the lower part of the support body 5 to guide the punch sheet 6 so as to be movable back and forth along the two warp directions, and the part of the guide passage 7 facing the thread hook 4 is open. The punch sheet 6 is further provided with a feeding mechanism that advances the punch sheet 6 by one horizontal row of punch holes, which will be described later.

First, the support body 5 is formed to be able to swing freely by forming a plurality of guide grooves 10 on the upper surface of the distal end thereof and having pivot shafts 11 attached to both sides of the main body 1 on the outer side of the proximal end. There is.

The thread hook 4 has a thread hook 13 formed in the upper part of a body part 4a whose cross section corresponds to the guide groove 10, a bar-like leg part 14 in the lower part, and a retainer 15 in the body part 4a. It is formed to protrude laterally and is fitted into the guide groove 10 of the support body 5 so as to be vertically movable. At this time, the thread hook 4 is configured to be prevented from slipping out from the support body 5 by a stopper 15.

16 indicates a marker. The marker 16 includes a body portion 16a and a rod-shaped leg portion 17 having the same configuration as the thread hook 4.
In addition, a thread locking piece 18 is formed on the upper part of the body portion 16a. The marker 16 is normally fitted into the guide grooves 10 on both outer sides of the support body 5 so as to be vertically movable.

The guide passage 7 is formed by attaching an upper plate member 7a and a lower plate member 7b to the main body 1 one above the other, and is open at the front and rear ends. The guide passage 7 also has an opening 1 in a portion facing the thread hook 4 attached to the support 5.
9 is formed. Furthermore, guide pieces 20 for a plain weave sheet, which will be described later, are formed on both sides thereof.

Feed holes 21 are formed in vertical rows at regular intervals on both sides of the punch sheet 6, and drop holes 22 for markers are formed alternately every other feed hole 21 on both sides of the inner side, and furthermore, inside the holes 21 are formed with thread holes. Hanging drop holes 23 are formed in vertical and horizontal rows along the feed hole 21. The spacing between the horizontal rows of the thread hook drop holes 23 is set according to the upper and lower thread distribution of the warp threads 2, and the portion where the drop holes 23 are formed is the portion where the bobbin threads 2b are formed; The unformed portion 23a is a portion where the upper thread 2a is formed.

Next, the punched sheet 6 inserted into the guide path 7 is advanced by the feeding mechanism. This feeding mechanism is constituted by the rotation of a gear that is interlocked with the upward movement of the support 5. First, handles 24 are swingably provided on both sides of the main body 1, and a cam 25 is formed on the handles 24. The cam 25 is provided facing the cam receiving shaft 12 of the support body 5,
By swinging the handle 24, the cam 25
pushes up the cam receiving shaft 12, thereby causing the support body 5 to move upward. At this time, a claw 26 biased by a spring 27 is provided on the side of the support body 5.
The pawl 26 meshes with a ratchet wheel 28 formed on the side of the main body 1. A feed wheel 30 is fixed to the ratchet wheel 28 and the same shaft 31, which has protrusions 29 on the outer circumferential surface that are equal to the spacing between the feed holes 21 of the punched sheet 6. Further, the feed wheel 30 is connected to the feed holes 2 on both sides of the punch sheet 6.
A protrusion 29 is provided to engage with the lower part of 1. Therefore, when the support 5 moves upward, the claw 2
6 rotates the ratchet wheel 28 by a predetermined rotation angle, and as the feed wheel 30 rotates in conjunction with this, the protrusion 29 that engages with the feed hole 21 of the punch sheet 6 moves the punch sheet 6 by one feed hole. Just postpone it.

Note that the feeding mechanism for the punched sheet 6 is not necessarily limited to the one described above. Any other mechanism may be used as long as the punch sheet 6 is advanced by one feed hole 21 in conjunction with the upward movement of the support body 5. When using the handloom A having the above configuration, first, the handle 24 is operated to move the support body 5 upward, and after inserting the punched sheet 6 into the guide passage 7, the handle 24 is returned to its original position. At this time, the thread hook 4 descends onto the opening 19 of the guide passage 7. Since the opening 19 faces the first horizontal row of holes 23 of the punch sheet 6, the legs 14 of the thread hooks 4 facing the holes 23
Fall inward and sink. Those not facing the drop hole 23 are held in the same position because the legs 14 touch the upper surface of the punch sheet 6. By distributing the thread hooks 14 vertically in this way, the warp threads 2 are also distributed vertically. Therefore, these upper and lower threads 2a,
Pass the shuttle between 2b. After that, when the handle 24 is swung, the feed mechanism is activated and the punch sheet 6 is advanced by the next horizontal row.
When it is returned to its original position, the thread hanging device 4 and the warp threads 2 are distributed vertically according to the punched drop holes 23 as described above, so the shuttle is inserted on the opposite side. By sequentially repeating this operation, the weave pattern of the pattern completed by the punch sheet 6 is completed.

Next, according to the punched sheet 4, in addition to the vertical distribution of the warp threads 2, the markers 16 also move up and down along the drop holes 22 of the punched sheet 6. Therefore, by attaching a piece of the weft thread actually used to the upper end of this marker 16, it is possible to fully confirm whether the feed has been carried out when this marker 16 goes up, and which color thread will be woven next. Can be done.

Hand-weaving is also possible with the above punched sheet 6, but in this case the upper and lower distributions only need to be done alternately, so this can be achieved by reciprocating the plain weave sheet 32 shown below in the lateral direction. Can be done. That is, the pit holes 23 are formed in the plain weave sheet 32 at intervals of every other warp thread, and
A sliding shaft 33 is formed on the lower surface of one end, and by engaging with the guide piece 20 for the plain weave sheet 32 on the upper plate 7a of the guide passage 7, it can be slid in the direction perpendicular to the warp threads 2. It is configured. On the other hand, the main body 1 is rotatably provided with a gear 34 that meshes with a gear 37 fixed to the end of the shaft 31 of the ratchet 28, and a grooved wheel 35 is fixed coaxially with the gear 34. The groove wheel 35 has a wave-shaped sliding groove 36 formed on its outer peripheral surface, and the sliding shaft 33 of the plain weave sheet 32 is inserted into the sliding groove 36.

With the above configuration, the feeding mechanism operates when the support body 5 moves up and down, and the gear 3
When the groove wheel 4 rotates, the groove wheel 35 also rotates by the same rotation angle. Therefore, the sliding shaft 33 along the sliding groove 36
slides, and the warp thread 2 moves to the right or left along the sliding direction.
Move by one eye. When the support body 5 next moves up and down, it slides in the opposite direction. In this way, weft thread 3
Each time the thread is woven one by one, it alternately moves in the opposite direction, so the thread hook 4 facing the plain weave sheet 32 alternately moves upward and downward.
The warp threads 2 are accordingly distributed alternately above and below, which makes plain weaving possible in a simple manner.
