Description

[Detailed Description of the Invention] Conventionally, when sewing fixed nets, purse nets, rod receiving shrines, fish tank 4j4, etc., the sewing of ropes and shrines has been an important element that accounts for the majority of the sewing work, but it all depends on manual labor. We are celebrating the opening of many people and time. The process is to wind the sewing thread around the end needle, and as shown in Fig.
While aligning the stitches, insert the brush needle into the stitches and sew the stitches together.
Knots are tied at regular intervals, which is all done manually and requires a lot of patience.

This is an issue that needs to be resolved urgently, as the fishing industry is getting older and the number of tailors is becoming more diverse and larger.
The major reasons why it was not possible to
In addition to the wide variety of net thread sizes, the main reason for this was that it was not possible to find a way to align the eyes with each other because they were custom-made for shrines and could be stretched freely in the slope and horizontal directions. .

The present invention successfully solves the problems with boards, and allows fishers to match the fish to the desired size several times faster than by hand, and provide it to fishermen quickly and at low cost. It is possible.

Hereinafter, an example of implementing the present invention will be described based on the accompanying drawings.

The present invention partially improves a popular sewing machine so that sewing can be performed individually by utilizing the relationship between the upper thread and lower thread of the sewing machine. is a main shaft pulley, and when the pulley is 1, the needle 3 moves one time in the vertical direction on the table 4.

5 is an iron piece attached to the outer periphery of the pulley 2 at a position tm, and 6 is a proximity switch provided at an outer position corresponding to the pulley 2, so that the rotation μ of the sideley 2 is detected by the proximity switch 6. It has become.

Normally, one revolution of pulley 2 moves a total of 8 back and forth, so it can be calculated by counting. At this time, 8a is a counter for setting the number of stitches, 8b
8e is an anti-unraveling pitch counter for setting conditions such as how many days the anti-unraveling pitch is to be performed.
is a counter that sets the number of stitches to prevent unraveling, and is set higher than the normal count.

3 and 4 schematically show the entire apparatus, the former being a side view and the latter being a plan view. In addition, FIG. 5 is a partially detailed enlarged view of the chain-dot circle in FIG.

In each figure, lO is a pair of h'4 A, B k to be sewn together at the 111th plane position of the sewing machine body L, with the ears aligned by a certain size corresponding to the 7th stitch pitch, so that they are parallel to each other on a plane. This is a sheet feeding device for conveying a sheet, in which a pair of freely rotating rollers 11a and 11b are provided facing each other at a certain distance, bells 12 are stretched on both roller surfaces, and A large number of iron pieces 13 are placed at regular intervals on the top surface of the plate 12.
is buried. In this case, the distance l between the 4D matching iron pieces 18 is made equal to the seam pitch p of the mesh.

In addition, 14 is a locking bottle installed on the bell) 12, which is provided at a position opposite to the center dividing line 0-01 in the length direction of the bell) 12, and has a sewn mesh. It is hooked onto the ni' at the joint section and moves to A and B all at once.

15 is a belt 12 ml in which the iron piece 13 is embedded.
This is a proximity switch provided below the proximity switch 15, and when the iron piece comes into contact with the proximity switch 15 due to the rotation of the belt, the rotation of the drive motor is stopped.

16 is a feed roller, 17 is its rotating shaft, and l-
A well-known one-way clutch 18 is provided in the 1lI end thread part, and this clutch 18 causes the feed roller 16 to be rotated between threads by a lever 19 that swings in conjunction with the rotation of the sewing machine pulley, thereby causing a small amount of thread to be applied to the net. I will make sure that the sending is done. It also serves to disconnect the feed roller 16 from the lever 19 at 9 o'clock when the feed roller 16 is rapidly moved by the motor.

Reference numeral 20 denotes a motor for rapidly feeding the feed roller 16 according to the mesh pitch p, and the rotation of the motor 20 is performed by rotating the rotation shaft 17t via the drawing wheels 21 and 22. ing.

At this time, reference numeral 23 is a one-way clutch provided at the gear 21 to prevent intermittent rotation by the lever 19 from being transmitted to the motor 20 while the motor 20 is stopped. The motor 20 is turned on when the iron piece 5 comes into contact with the proximity switch 6 due to the rotation of the pulley 2, and this causes the feed roller 16 to rotate and the metal piece 14 to be fed out. pin i44 to pin 14
When one of the iron pieces 13 buried on the belt comes into contact with the proximity switch 15, the needle 3 is turned off, and specifically, the needle 3 is moved to a slightly deviated position on the mesh as shown in the third example. During this period, the motor 20 drives the feed roller 16, which is driven by the motor 20 to move the feed roller 16 through the joints between the meshes. It's like sending darkness, so it's 6. This way, the needle will not pierce the masonry part while feeding the shrine. After this, the needle enters between the meshes and aligns the adjacent meshes, but if the number of implants I+ is other than 1, that is, 2.3, the motor 20 The off operation is performed by the pulley 2 turning twice, turning three times, etc., and this is done by setting the number of stitches setting counter 8a.

The present invention has been constructed as described above, and the stock to be used will now be explained. First, a belt 12 with iron pieces embedded at equal intervals according to the mesh size and pitch P) is moved to the roller 1.
1j, 11b+ tone.

Next, the count to be entered is set using the count setting counter 8a. On the other hand, the short intermittent feed of the feed roller 16 is possible because the driving pitch of the needle 3 is adjusted as appropriate with the existing adjustment table located on the sewing machine body depending on the size of the mesh, the number of stitches, etc. , the distance E in FIG. 5 is determined by the setting of the number of stitches and the length of the driving pitch 14.

On the other hand, depending on the anti-unraveling pitch, that is, how many devices are used to perform unraveling, for example, if this is set to 4, the unraveling will be performed every fourth position. On the other hand, 8
r-tzpi is a counter for setting the number of stop stitches, and is set in a larger number than the normal count.

When the above-mentioned operations are completed, as shown in FIG.
1 and guide it to the presser plate 25 and the lower surface of the feed roller 16 on the side of the sewing machine body 1 while holding the ears of fiA and B with pins 14, and
A suitable tension is applied to A%B.

Then, start the sewing machine needle from above the marked point in Fig. 5, move the main shaft pulley by -20 rotations, and move %A and B by the interval E in Fig. 5 by minute 1ml intermittently rotation of the feed roller 16. During that time, only the set count is entered, so at the end of the 69.E interval (the end of the set number of stitches), that is, when it approaches the (goods) point, the shimotor 20 is turned on in response to the command from the count setting counter 8a, and the XA , B, and by the time the needle comes out of the net and comes down again, it has rotated 1!1il through gears 21 and 22.
117 is rotated to fast-forward to the final point of the F+Mi interval. At this time, the rapid feed multi-speed is rotation 1+l1l117 at a speed exceeding the minute feed speed by the lever 19.
is rotated continuously, and the connection with the sillper 19 is broken by the one-way clutch 18, while the pin 14 of the tape 12 is pulled toward the set Mli and moved together with the net. One of the iron pieces 13 on the belt is the proximity switch 1.
5, the motor 20 is turned off f'1li-d
Then, the fast forwarding is canceled.

This release is performed at point e4, where d4A and B have moved a distance of F. Subsequently, the rotation of the feed roller 16 is switched to intermittent rotation with a small amount of fading due to the operation of the lever 19, and during this time the rotation is set by the setting counter 8a. The i-alignment is performed by punching the set number of stitches that have been set. Thereafter, the process is performed in the same manner, and when the set number of days is reached, the unraveling is performed at that location by the number of times set by the anti-unraveling pitch setting counter.

In the present invention, the pins 14 are implanted at a pitch that is an integral multiple of the mesh size, so that they automatically enter fixed positions between the meshes one after another during the movement of the rope, and the bell (12) It becomes something that always moves in the same way as the net.

FIG. 6 is a detailed view of a part of the stitches sewn in this way [A, B: 5-], in which m is the upper thread and n is the lower thread. In this example, the number of stitches to be driven is 2, the anti-unraveling pitch is 4, and the anti-unraveling count is 4. In this example, a wood-stitch zigzag sewing method is used as the sewing machine sewing method, but the sewing method is not limited to this, and various known methods can be adopted.

As mentioned above, (2) it is possible to carry out tailoring work reliably, and there is no possibility that the sewing needle will break or stick in the system or its sash. Therefore, it goes without saying that there is no need to attach the net, and it is also possible to perform arbitrary counting and prevention of unraveling, which contributes to a dramatic improvement in work performance.

The present invention can be used by making slight modifications to existing sewing machines, does not require any skill, and can be implemented quickly and inexpensively, thus meeting the needs of a wide range of fishermen. .
