形成される。2. Description of the Related Art Conventionally, a sewing machine equipped with an embroidery frame feeding device (for example, Japanese Patent Application Laid-Open No. 2-80084) is provided with a sinking mechanism for sinking a feed dog from a needle plate. The sinking mechanism releases the vertical movement mechanism for vertically moving the feed dog by moving the lever, and causes the feed dog to sink from the needle plate. In a conventional sewing machine, the lever of the lowering mechanism is connected to a switching lever exposed to the outside. The operator operates the external switching lever to lower the feed dog from the needle plate, and then mounts the embroidery frame feeding device on the sewing machine. If the feed dog sinks below the needle plate, the movement of the embroidery frame performed by the embroidery frame feeding device works together with the vertical movement of the sewing needle of the sewing machine without being disturbed by the feed dog, and the desired movement of the work cloth attached to the embroidery frame is achieved. Embroidery is formed.

る。On both sides of the eccentric cam 45 of the vertical feed drive mechanism 23, a flange portion 45a and a concentric cam portion 45b are integrally formed. The outer diameter of the concentric cam portion 45b is the same as the minimum diameter of the eccentric cam 45 (the portion where the distance from the center of the lower shaft 43 is the shortest). Therefore, a part 45c is formed between the eccentric cam 45 and the concentric cam part 45b. As shown in FIG. 3, a cutout 45d is formed in the concentric cam 45b in the axial direction of the lower shaft 43. A pin 46 that engages with the notch 45d is attached to the lower shaft 43. With this configuration, the eccentric cam 45 and the flange portions 45 a and the concentric cam portions 45 b on both sides thereof do not rotate with respect to the lower shaft 43, but can slide in the axial direction of the lower shaft 43.

5 is arranged to be swingable in the horizontal direction by a shaft 57. On the lower surface of the end of the horizontal rotation lever 55, the above-described operation projection 1
3 are provided. On the upper surface of the other end of the horizontal rotation lever 55, a contact projection 59 that contacts the flange 45a of the eccentric cam 45 is provided. Therefore, horizontal rotation
The lever 55 and the abutting projection 59 move the action projection 13 eccentrically.
It functions as an interlocking unit for connecting to the system 45. The horizontal rotation lever 55 is pulled by a tension spring 61 fixed to a frame (not shown), and the contact protrusion 59 is
It is urged to the 5th side. The spring constant of the tension spring 61 is smaller than the spring constant of the compression spring 53.

The vertical lever 47 moves up and down along the outer peripheral shape of the eccentric cam 45 by the rotation of the lower shaft 43, and vertical feed is applied to the feed dog 25. The feed dog 25 protrudes from the needle plate 3 at the raised position, moves in a predetermined direction by the operation of the front-rear feed drive mechanism 21, and transfers the work cloth on the surface of the needle plate 3. The feed dog 25 sinks below the needle plate 3 at the lowered position, and the front / rear feed drive mechanism 21 operates to return the front / rear position to the position before the transfer of the work cloth.

を保つ。When the embroidery frame feeder S is mounted on the sewing machine 1, the pushing piece S3 provided on the embroidery frame feeder S pushes out the working projection 13 of the sewing machine in the direction of arrow A in FIG. . Then, the contact protrusion 59 moves the flange portion 45a against the pressing force of the compression spring 53, and arranges the concentric cam portion 45b below the sub-portion of the vertical movement lever 47. Since the concentric cam portion 45b has the same outer diameter as the minimum diameter of the eccentric cam 45, in this state, even if the lower shaft 43 rotates, the vertical movement lever 47 does not rise. That is, as shown in FIGS. 7 and 8, the feed dog 25 is kept sunk from the needle plate 3.

成される。When the embroidery frame feeder S is mounted on the sewing machine 1, the feed dog 25 is sunk below the needle plate 3. Therefore, the embroidery frame S1 of the embroidery frame feeder S is not disturbed by the feed dog 25. The movement and the vertical movement of the sewing needle 9 of the sewing machine work together to form a desired embroidery on the work cloth mounted on the embroidery frame S1.

加工布の送りが可能になる。When the embroidery frame feeding device S is removed from the sewing machine 1,
The extruded piece S3 separates from the working projection 13. Then, the eccentric cam 45 is biased by the compression spring 53 toward the lower part of the sub-part of the vertical movement lever 47. Since there is a surface 45c between the eccentric cam 45 and the concentric cam portion 45b, when the surface 45c is rotated to the position of the vertical movement lever 47 by the rotation of the lower shaft 43, the eccentric cam 45 is urged. Moves to the lower part of the sub-part of the vertical movement lever 47. Thereafter, the eccentric cam 45 moves the vertical movement lever 47 up and down, and enables the feeding of the work cloth in which the feed dog 25 projects from the needle plate 3.

う効果を奏する。According to the sewing machine described above, the feed dog 25 is attached to the needle plate 3 only by mounting the embroidery frame feeding device S on the sewing machine.
Since the operation of lowering the feed dog 25 automatically becomes unnecessary, the possibility of erroneous operation can be basically eliminated.
