JPS6036227Y2 - Net suturing device in sewing machine - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a net stitching device for overlapping required portions of joints of nets, particularly fishing nets, and sewing these portions together using a sewing machine.

Traditionally, a thick rope was inserted through the mesh at the top of the fishing net to lower the fishing net into the sea and wind it up when harvesting fish, but this part was folded back to withstand strong tension and friction. It was reinforced with a double mesh structure.

However, in order to do this, long net threads made of the same material were manually entwined around the joints of the fishing nets, creating a double overlap and fixing the seams.

This has the disadvantage that a large amount of mesh yarn is consumed, which is uneconomical, and the work must be done manually, which takes a long time.

The object of this invention is to provide a mesh suturing device for a sewing machine that can eliminate these drawbacks.

An embodiment of this invention will be described below with reference to the drawings.

In Fig. 1, 1 is a bed of a cycle sewing machine 2, 3 is a workpiece moving plate supported on the machine frame 4 of the sewing machine so that the upper surface of the bed 1 can be moved back and forth and left and right in synchronization with the needle N, and 5 is a workpiece movement plate. This is an X-shaped needle hole that is opened approximately in the center of the plate 3 and through which the needle N is inserted.

6.7 is a silk thread guide portion 6a, which is disposed on the periphery of the needle hole 5 of the workpiece moving plate 3, facing each other with the needle hole 5 in between. A pair of ■-shaped first guide bodies having a.

8 is a presser arm supported on the machine frame so as to be movable back and forth and left and right in conjunction with the workpiece moving plate 3; 9 is a presser foot supported at the tip of the presser arm 8 so as to be movable up and down; It is located above the object moving plate 3 and comes into contact with the sewing object moving plate 3 by descending.

Reference numeral 10 denotes an X through which the needle N, which opens approximately in the center of the presser foot 9, is inserted.
It is a letter-shaped needle hole.

11.12 forms a gap R that is located between the opposing first guide bodies 6 and 7 and holds the mesh thread FT when the presser foot 9 descends and comes into contact with the workpiece moving plate 3; A pair of ■-shaped second guide bodies are disposed on the lower surface of the presser foot 9 to face each other in a direction orthogonal to the opposing direction of the first guide bodies 6 and 7, sandwiching the needle hole 10 of the presser foot 9.

(See FIG. 2) In addition, lla and 12a are the second guide members 11.
There are 12 guide sections.

13.14 is a mesh thread FT installed on the upper part of the sewing material moving plate 3
This is a pin for locking.

In addition, the above-mentioned No. 1. Although a V-shaped second guide was used, a pin-shaped one with a curved peripheral wall may also be used.

Next, the operation of this invention will be explained.

First, the presser foot 9 is raised as shown in FIG.

Next, as shown in FIG. 3, the desired connection @vt of the net thread FT on the upper part of the fishing net F is placed in the center of the needle hole 5 of the sewing material moving plate 3,
The mesh threads FT connected to this joint portion Ft are made to run along the (1)th guide bodies 6 and 7, respectively.

Then, the upper mesh thread FT of the mesh thread FT connected to the joint part Ft
is hooked onto pins 13 and 14.

Thereafter, as shown in FIG. 4, the uppermost joint yt of the fishing net F facing the joint Ft is folded back so as to match the joint Ft, and the joint Ft1 is overlapped with the joint Ft, and the joint Ft□ The mesh threads FT connected in the .

When the presser foot 9 is lowered in this state, the silk thread FT is moved between the first guide members 6, 7 and the second guide member 11.1 formed on the lower surface of the presser foot 9.
2 and is reliably fixed and held within the X-shaped gap R formed by the two.

When the sewing machine is started, the workpiece moving plate 3 and the presser foot 9 are
moves back and forth and left and right so that the needle N falls into the X-shaped needle holes 5 and 10, and forms an X-shaped stitch in the mesh thread FT centering around the joints Ft and Ftl, thereby creating the joints Ft, Suture Ftl.

By repeating the above operations and sewing the joining part of the net thread FT at the upper end of the fishing net F and the joining part at the upper part opposite to this joining part, the mesh at the upper body end of the fishing net F will become a double mesh part. It will form quickly.

Then, a thick rope is inserted through this double mesh portion, and this rope is connected to a winding machine for use.

As described above, according to this invention, a pair of V-shaped first guide bodies arranged on the workpiece moving plate and a pair of V-shaped second guide bodies arranged on the lower surface of the presser foot are used to connect the joints of the net. The mesh can be held accurately and reliably, the joints of the net can be sewn accurately and firmly, and the work time can be greatly shortened compared to the conventional manual connection work. play.

Claims (1)

[Scope of Claim for Utility Model Registration] A workpiece moving plate having a needle hole and supported on a machine frame so as to be movable back and forth and left and right on the top surface of the bed, and a workpiece moving plate placed oppositely on the top surface of the workpiece moving plate with the needle hole in between. A pair of first guide bodies each having a guide portion for the mesh thread, and a needle hole, which are supported on the machine frame so as to be able to move upwardly and downwardly towards and away from the object moving plate, and move forward, backward, left and right in conjunction with the object moving plate. a presser foot that moves to the workpiece moving plate; and a guide section that is opposed to the guide section of the first guide body when the presser foot comes into contact with the workpiece moving plate; Stitching of a net with a sewing machine comprising a pair of second guide bodies which have a needle hole in the lower surface of the presser foot and are arranged opposite to each other in a direction perpendicular to the opposite direction of the first guide body so as to form a gap for holding the net thread.
