On the other hand, in case drive the motor 71 of above-mentioned longitudinal moving mechanism 12, because the tooth-strip part 64 that is installed in the gear 72 on this motor 71 and is formed on the length feed axle 62 meshes, therefore this length feed axle 62 just is along the longitudinal movement, thus, the feeding platform 10 that is connected on this length feed axle 62 by linking arm 65 is along the longitudinal movement.At this moment, when above-mentioned feeding platform support 14 is depicted arc track ground when mobile in the horizontal, feeding platform 10 and this feeding platform support 14 move with depicting arc track together in the horizontal, but owing to allow that by above-mentioned linking arm 65 this feeding platform 10 moves, thereby feeding platform 10 also can move by length feed axle 62 when moving with depicting arc track in the horizontal in the vertical.
And linking arm 65 cooperates along horizontal mobile phase with this feeding platform 10, rotation and inclination in horizontal plane, and this inclination causes that linking arm 65 is along the longitudinal movement.In this occasion, to driving vertically with CD-ROM drive motor 71, length feed axle 62 is moved with the opposite direction of the direction that is along the longitudinal movement, thus mobile on vertically carried out revisal.
Like this, move and longitudinal moving mechanism 12 causes that longitudinally mobile of feeding platform 10 controlled aptly along horizontal circular arc by the feeding platform support 14 that makes that above-mentioned transverse moving mechanism 13 is caused, this feeding platform 10 is moved along both direction in length and breadth reliably.
In the feeding table driving device of present embodiment, feeding table driving device 11 is made of longitudinal moving mechanism 12 and transverse moving mechanism 13, because these two travel mechanisms 12,13 are configured in the rear of feeding platform 10, even so cut off when cloth that is produced when leaving buttonhole on the sewn object on being supported on feeding platform 10 or sewing finishing the end of a thread that is produced behind sewing line and the heart yearn fall feeding platform 10 below, this cloth or the end of a thread can not enter longitudinal moving mechanism 12 and transverse moving mechanism 13 gear 72 separately yet, 53 and tooth bar 64, in 25, thus, it is bad to have prevented to enter because of cloth or the end of a thread the action of the feeding platform 10 that brings.
Moreover, because on all directions of vertical and horizontal, the engagement of gear 72,53 and tooth bar 64,25 is carried out a position respectively, therefore can easily carry out the adjustment of backlash.
In addition, feeding platform support 14 is done in a rectangular shape, rotary driving force is from actuating arm 21, be delivered to four jiaos of this rectangle reliably by leading truck 15A, 15B and connecting plate 31, therefore, improve the rigidity of feeding, can realize the correct feeding of feeding platform 10, as a result, improved the quality of the needle tracking that is bearing in the sewn object on the feeding platform 10.
