Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery machine for sewing a tape on a sheet-like member by a sewing head while drawing an embroidery pattern using the tape. The tape is swung to represent a zigzag pattern. Related to moving jigs.

[0002]

2. Description of the Related Art Hitherto, an embroidery pattern has been sometimes expressed on clothes, tablecloths and the like by a tape made of embroidery thread. For example, a lace pattern composed of a curved pattern or a zigzag pattern using a tape may be displayed on a table cloth. Such an embroidery pattern is usually formed by sewing a tape made of embroidery thread onto a sheet-like member by one or more sewing heads while controlling the movement of the base on which the sheet-like member is sewn in two-dimensional directions. It is represented by an embroidery machine capable of representing an embroidery pattern by the tape.

As an example of a sewing head of such an embroidery machine, a sewing head 1 is shown in FIGS. The sewing head 1 includes a swing jig 2 and a tape 3.
Can be swung to represent a zigzag pattern. The swing jig 2 is composed of a link 4 and a lever 5 and is driven by a driving shaft.
Is moved up and down, the ring-shaped member 7 is slid up and down, and the lever 5 is reciprocated by the link 4 to swing the guide base 8 attached to the tip of the lever 5. It is configured as follows. That is, by swinging the guide base 8, the tape 3
Is swung so that a zigzag pattern by the tape 3 can be drawn.

[0004]

However, according to such a swing jig 2, it is possible to represent a zigzag pattern by the tape 3, but it is not possible to represent a more complicated pattern. For this reason, it was difficult to represent a desired pattern, and the commercial value could not be increased. In particular, it was difficult to represent a lace pattern obtained by crossing tapes representing a zigzag pattern.

The inventor of the present invention has intensively studied to solve such a problem, and has reached the present invention.

[0006]

The gist of the swing jig according to the present invention is that a base on which a sheet-like member is fixed is formed by two bases.
An embroidery machine is provided with an embroidery machine capable of displaying an embroidery pattern using the tape by sewing a tape made of embroidery thread to the sheet-like member by one or more sewing machine heads while controlling movement in a three-dimensional direction. A rocking jig for displaying a zigzag pattern on the sheet-like member by continuously rocking a guide holding the tape near the sewing machine needle in a direction substantially perpendicular to the moving direction of the substrate; The pair of the sewing heads is provided in such a manner that the guides are continuously oscillated in mutually opposite directions so that the single sewing head can represent a zigzag pattern formed by the two tapes.

When such a swinging jig comprises, for example, a link and a lever, first, the embroidery machine is operated to move the substrate, thereby enabling sewing with a sewing needle. Thus, the two links forming a pair are simultaneously reciprocated up and down. When the two links are reciprocated up and down at the same time, the paired two levers are reciprocated in opposite directions. By the two levers being reciprocated in the opposite direction,
The two guide bases forming a pair are reciprocated in opposite directions. When the two guide bases are reciprocated in the opposite directions, the two guides attached to the ends of the two guide bases are reciprocated in the opposite directions. In this manner, the two guides are reciprocally oscillated in the opposite directions while the substrate is being moved, whereby a pattern in which the two tapes extend in a zigzag manner on the sheet-like member is displayed.

[0008] The gist of the swing jig according to the present invention is that two guides forming a pair are successively swung in the opposite direction while intersecting each other, thereby forming two tapes. Can represent a pattern extending in a zigzag manner while intersecting.

In such a swing jig, two swing jigs forming a pair swing in the opposite direction while intersecting each other, and the two guide bases swing back and forth in the opposite directions to each other. This causes the two guides attached to the two guide base tips to reciprocate in the opposite direction while intersecting. In this way, while the substrate is being moved, the two guides are reciprocally oscillated in the opposite direction, whereby a pattern in which the two tapes intersect and extend in a zigzag manner on the sheet-like member is represented. Go.
