Problems solved by technology

As a result, the working space in the left and right directions of the sewing machine bed is reduced due to the increase in the size of the sewing machine as a whole or the narrowing of the distance between the pillar part and the needle bar, resulting in poor workability.

Embodiment Construction

[0016] Refer below Figure 1 ~ Figure 3 An embodiment of the present invention applicable to a needle-feed lockstitch sewing machine is described.

[0017] Such as figure 1 As shown, the needle-feed lockstitch sewing machine M has a sewing machine chassis 10 extending in the left-right direction. A pillar portion 11 extending upward is provided at the right end portion of the sewing machine chassis 10 . Further, at the upper end portion of the pillar portion 11, a sewing machine arm 12 facing the sewing machine chassis 10 and extending leftward is provided. A sewing machine head 13 is provided at the left end portion of the sewing machine arm 12 .

[0018] An upper shaft 15 extending in the left-right direction is provided inside the sewing machine arm 12 . Such as figure 2 As shown, the upper shaft 15 is rotatably mounted on the frame 14 of the sewing machine M through a plurality of bearings 17 and 18 (only two are shown), and is rotationally driven by an unshown sewin...

Abstract

The needle feeding sewing machine (M) of the present invention comprises: a horizontal feeding shaft (32) that reciprocates with the rotation of the lower shaft (16) to move the feeding dog (45) along the front and rear directions; Shaft (32) interlocking, the needle bar swing shaft (42) that makes the needle bar seat (22) swing in the feeding direction; and the reciprocating rotation of the horizontal feeding shaft (32) in the pillar part (11) The linkage mechanism (35) transmitted to the needle bar swing shaft (42), the swing lever member (43) that constitutes the linkage mechanism (35) is arranged between the upper shaft timing pulley (28) and the lower shaft. The inner side of the timing belt (29) between the shaft timing pulleys (27). Thereby, the width direction of the pillar part (11) can be miniaturized and the needle feed sewing machine (M) can be miniaturized, or the working space on the sewing machine base plate (10) can be enlarged to improve workability.

Description

technical field [0001] The invention relates to a needle-feeding sewing machine capable of feeding processed cloth through the cooperative movement of a sewing needle and a cloth-feeding dog. Background technique [0002] For example, in a sewing machine for lockstitching, usually when sewing a processed cloth, the processed cloth held on the needle plate is fed in the front-rear direction by means of a feed dog. In this case, the cloth feeding operation is performed with the sewing needle at the raised position, that is, with the sewing needle pulled out from the cloth to be processed. However, when processing cloth, such as thick material such as denim, due to the weight of the denim, the material cannot be fed correctly by the above-mentioned feed dogs. For this reason, for the processing cloth of thick material such as above-mentioned denim, in order to carry out feeding correctly, there is known a kind of needle-feed sewing machine such as the record in Japanese Patent...
