Description

Description: TECHNICAL FIELD The present invention relates to a sewing machine string material sewing device capable of appropriately sewing a sewing material for binding and other purposes to a sewing product during sewing work. Is.

2. Description of the Related Art Conventionally, for the purpose of preventing displacement of a sewn product such as a duvet cover or bed sheet during use, a string material having a length of about 20 to 30 cm for binding is provided at a predetermined position of an edge portion. Is being implemented.

In the sewing work using the sewing machine, the duvet cover, the bedcloth, and the like having such a configuration temporarily stop the operation of the sewing machine during the sewing work, and the operator manually sew a predetermined length of cord material to the predetermined sewing operation. By adding to the position and restarting the sewing machine operation, the string material is sewn in.

Problems to be solved by the invention As described above, the sewing of the string material in the sewing work of the sewing machine such as the duvet cover and the bedclothes depends on the manual work of the operator as described above, and the sewing work of the sewing machine is interrupted each time. It was necessary to do so, and the skill of the worker was required, and the work efficiency was poor.

An object of the present invention is to provide a sewing machine for sewing a string material of a sewing machine which can improve the work efficiency by mechanizing the sewing of the string material in the sewing work of a sewing material such as a duvet cover and a bed sheet. is there.

Means for Solving the Problems A configuration of the present invention for achieving the above object will be described with reference to FIGS. 1 to 3 corresponding to an embodiment, and a sewing machine for sewing a sewing machine according to the present invention. Is a string material supply base 1 for guiding and supplying the string material 4 in an expanded state immediately before the sewing machine sewing line.
And a cord pull-out rod 5 which has a clamping mechanism 7 capable of clamping the tip of the cord 4 on the cord supply table 1 and which moves back and forth in a direction traversing the sewing line, and the cord 4 pulled out. The present invention is characterized in that a cutter 10 for cutting is cut.

Action With the above-mentioned means, at the predetermined stage of sewing work of the sewn product K such as the duvet cover and bed sheet with the sewing machine, the pinching mechanism portion 7 provided at the tip end of the string material pulling rod 5 is operated to operate the string material. The tip end portion of the string material 4 placed on the supply table 1 in an expanded state is clamped. Under such a state, the cord pulling rod 5 is moved in a direction crossing the sewing line of the sewing machine, and the cord 4 is pulled out on the material cloth at the position to be sewn now.

The string material 4 pulled out by this is guided under the presser foot P of the sewing machine in a state of being added to the material cloth, and is sewn on the sewing machine to be sewn on the sewing product K. At the same time, the cutter 10 cuts the string material 4 pulled out at a predetermined position.

At this stage, the gripping mechanism 7 at the tip of the cord pulling rod 5 is released to open the tip of the pulled cord 4 and to retract and return the cord pulling rod 5.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A strip plate-shaped cord material supply base is provided on the side just before the sewing line of a sewing machine for sewing a sewing material K such as a duvet cover and a bed sheet. Install 1. The cord supply base 1 is slidably supported on a base 2 by a predetermined width, and is urged forward by a spring 3.
On the cord supply base 1, a cord 4 made of cloth tape or the like is installed in a horizontally expanded state with its tip facing in a direction orthogonal to the sewing line.

A string material drawing rod 5 is arranged in parallel with the string material supply table 1.
The cord pull-out rod 5 is formed of a plunger corresponding to the cylinder 6, and a tip end portion of the cord pull-out rod 5 holds the cord 4 by a clamping mechanism 7.
To provide. The holding mechanism portion 7 is composed of a fixed tongue piece 8 protruding downward from the side and a movable tongue piece 9 configured to be movable up and down above the fixed tongue piece 8. Further, a cutter 10 for cutting the cord material 4 pulled out from the cord material supply table 1 by the movement of the cord material pulling rod 45 feeds below the presser foot P having the needle hole H in the sewing machine. It is configured to swing by an appropriate means such as interlocking with a feed dog (not shown).

In the figure, reference numeral 11 indicates a cord supply table 1 by the movement of the cord pulling rod 5.
A cord material presser capable of moving up and down for appropriately pressing the cord material 4 pulled out from above, 12 is a cord material supply base for securing a path of the cord material 4 on the cord material supply base 1. A guide block provided on top of the guide block 1, and if necessary, the guide block
A spring or the like is provided inside 12 to urge the string material 4 by appropriately pressing it downward.

In the first illustrated state in which the sewing material K such as the duvet cover and the bed sheet is sewn by the sewing machine, at the stage where the cord material 4 is about to be sewn in, first, the cord material at the tip of the cord material pulling rod 5 is acted by the action of compressed air or the like. The movable tongue piece 9 in the holding mechanism portion 7 is moved downward, and the movable tongue piece 9 and the fixed tongue piece 8 located below hold the tip end portion of the cord material 4 from above and below at the tip end portion of the cord material supply base 1. To do.

Under such a state, the cord material drawing rod 5 serving as a plunger is advanced by supplying compressed air or the like to the cylinder 6 so as to cross the sewing line of the sewing machine. As a result, the cord supply table 1
In a state where only the upper string material 4 is clamped, as shown by a two-dot chain line in FIG. 1, it is pulled out laterally by a predetermined length onto the material cloth immediately before the sewing.

Here, the cord material presser foot 11 descends from above, and appropriately presses the drawn cord material 4, whereby the cord material 4 is guided so as to smoothly advance below the cloth presser foot P of the sewing machine. , The sewing machine is sewn and sewn into the sewing product K. At the same time, the string material 4 pulled out by the cutter 10 that swings is cut.

At this stage, the movable tongue 9 in the clamping mechanism 7 at the tip of the string material pulling rod 5 is moved upward to release the clamped state, and the distal end of the drawn string material 4 is released and the string material pulling rod is released. 5
To return to the state shown by the solid line in FIG. Here, the fixed tongue piece 8 in the holding mechanism portion 7 in the open state in which it recedes and returns integrally with the string material pulling rod 5 is the free end portion of the string material 4 on the string material supply base 1 cut by the cutter 10. Bend 13 to the lower surface of the leading end of the string supply base 1.

Effect of the Invention As described above, the present invention can realize the mechanized sewing of the string material in the sewing work of the sewing material such as the duvet cover and the bed sheet, and can significantly improve the work efficiency. Have.
