Description

[Detailed Description of the Invention] This invention relates to a sewing machine pricking device that performs pricking by operating a fixed tracing needle as a target on an original drawing so that the needle traces the original drawing.

The present applicant has previously proposed an embroidery device of this type that can be set up simply by placing the main body, which is equipped with a mounting surface for an original picture and a fabric tensioning section, on a bed.

According to this device, since the entire device is not supported by the sewing machine, there is no need to install or remove it from the sewing machine, and it has the advantage that it can be installed and removed from the sewing machine extremely easily. It does not cause much trouble when putting it in and taking it out, and it also has various advantages such as the ability to enlarge the fabric tensioning area and embroidery over a wide area at once, making it extremely excellent in practical terms. If the main body is not movable on a plane that includes the bed surface, that is, the device that supports the main body so that it can move back and forth and left and right independently of the sewing machine will tilt the main body even slightly with respect to the bed surface. There was a problem with the smooth movement of the main unit on the bed when it was supported by the support.

In this idea, the main body, which has a mounting surface for the original picture and a cloth covering section, can be moved back and forth and from side to side by means of a fixed plate supported by the bed, thereby ensuring smooth movement of the main body at all times.

To explain this using drawings, the first embodiment shown in Figs. 1 and 2 has a main body 3 on which a mounting surface 1 for the original picture and a mounting part 2 for a stitching frame (not shown) are formed, with one side attached to a bed 5. The main body 3 and the plate 6 are mounted on a rigid plate 6 made of resin or metal, preferably a plate whose surface has been treated with fluorine resin, and the main body 3 and the plate 6 have one end pivoted to the back surface of the plate. The other end of the pantograph mechanism 8 is connected to the pantograph mechanism 8 which is pivotally supported on the back surface of the main body through a window 7 formed in the plate 6, and as the mechanism bends and stretches, the main body moves back and forth and from side to side. is formed to a size that allows the necessary movement of the main body, that is, the pivot portion of the pantograph mechanism, so that the needle drop position can reach any position within the stabbing frame. 1
0 is a hole drilled in the plate 6 through which the needle passes, and it may be a small hole that allows the needle to pass through, but if the needle plate 11 slightly protrudes from the bed surface as shown in the figure (in many cases). (For sewing machines, this is done this way for processing reasons) The needle plate should be formed in a size that fits the needle plate, and the thickness of the plate should be equal to or smaller than the amount of protrusion of the throat plate from the bed surface.ゝIt is desirable to form it thickly. This is because the main body can move smoothly without hitting the throat plate.

13 is a plate 6 whose one side is placed on the bed 5
The foldable legs that support the other side may be attached directly to the back of the plate in a position where they do not interfere with the movement of the pantograph mechanism 8, but in the illustrated example, a cover that covers the pantograph mechanism is used. 14
is provided and attached to the back of the cover. Legs 13 are also preferably adjustable in length by known means. Reference numeral 15 is a handle for operating the main body 3, and reference numeral 16 is a tracing needle pointing toward the mounting surface 1 of the original.

Figures 3 and 4 show an example in which the longitudinal and lateral movement of the main body is carried out along each longitudinal direction of orthogonal rails, similar to that shown in Japanese Patent Application No. 57-25078 (Japanese Patent Application No. 58-144160). Of the pair of orthogonal rails, one rail 21 is attached to the cover 22 and the other rail 23 is attached to the main body 24, and the rail 23 attached to the main body has a rectangular window 2 bored in the plate 25.
6, and runners 27 are slidably engaged with both rails, respectively.

FIG. 5 shows yet another example, in which the cover 31
is formed on the plate 32, and the main body 33 is formed in two stages so that the cover 31 and the plate 3
A pantograph mechanism 35 is installed between the main body 33 and the plate 32.

In the one shown in FIG. 6, both sides of the plate 41 are bent to form a cross-sectional shape, and one side is fitted into the bed. This increases the bending strength of the plate and allows the main body 42 to be bent as shown in the figure. It does not bend even when moved to the left, the plate can be easily positioned on the bed, and the plate does not move inadvertently during the stabbing operation. In this embodiment, the length of the bent portion 43 is formed to be the same as the height of the bed surface, or it can be attached to the bed using a magnet, adhesive or other removable fastening means, or it can be attached to one side of the plate. If a fitting part is provided to the bed and it is fitted, plate 4
1 can be omitted.

In each of the embodiments described above, the pantograph mechanism or rail that guides the longitudinal and lateral movement of the main body is housed within the main body, but it may be provided in an exposed state outside the main body.

As described above, the embroidery device of the present invention is designed so that the main body, which includes the mounting surface for the original image and the fabric tensioning section, moves on a flat fixed plate, so the machine is attached to the sewing machine with the fixed plate slightly tilted. The main body can always move smoothly even when set.
