The following describes effect and the effect of the pay-off F of pattern sewing machine M.
Pattern sewing machine M has control device (not shown).Control device stores makes the stitch data that various styles, decorative pattern, figure are used, and comes drive controlling sewing machine body 1 and pay-off F according to the stitch data of the selected style of user, decorative pattern, figure.
During beginning pattern seam, top board 4 is followed the action of pressing mechanism 9 and is risen to be in and remove the position, between the lower platen 3 and top board 4 of processing cloth expanded configuration on workbench 2.Then, top board 4 is followed the action of pressing mechanism 9 and is descended and be in the cloth holding position, keeps processing cloth by the 3a of rectangle frame portion of lower platen 3 and the 4a of rectangle frame portion of top board 4.
Under the driving of fore-and-aft direction drive motor 53 and left and right directions drive motor 27, keep the lower platen 3 and the top board 4 of processing cloth on workbench 2, to move along all around direction.Move left and right plate 21 contacted an edge left and right directions with the upper surface of workbench 2 on one side and moved as previously mentioned this moment, and lower platen 3 and top board 4 contact an edge fore-and-aft direction with the upper surface of move left and right plate 21 on one side and move.
Below contact resistance and pushing precision about lower platen 3 and top board 4 edges, when fore-and-aft direction moves are described.Can only move along left and right directions with lower platen 3 and top board 4 with the move left and right plate 21 of workbench 2 contact.Therefore, with there not being move left and right plate 21 lower platen 3 keeping with the contact condition ground of workbench 2 along about, the occasion that moves of fore-and-aft direction relatively, contact amount of movement with respect to workbench 2 is about 1/2, and the wearing and tearing powder amount that contact site produced is reduced to about 1/2.
When lower platen 3 is made by synthetic resin, with the contact site of move left and right plate 21 on only produce the wearing and tearing powder of synthetic resin material.This wearing and tearing powder is not easy attached on the processing cloth, even and attached to also simply it being flipped on the processing cloth.Thus, can not resemble the wearing and tearing powder that lower platen 3 produced of steel plate system, can improve the quality of quilt yet attached on the processing cloth and the processing cloth of making dirty.
The move left and right plate 21 that contacts with the upper surface of workbench 2 directly is connected with left and right sides feeding table 23, can move at the state lower edge left and right directions that does not produce strain.The move left and right plate 21 that is connected with front and back feeding table 41 can not move at the situation lower edge left and right directions that can not produce the feeding error because of the influence of the minim gap between fore-and-aft direction track 41a and the front and back feeding table 41.
Because lower platen 3 moves along left and right directions integratedly with above-mentioned this move left and right plate 21, therefore, the strain of left and right directions can not take place in the connection board 3b of lower platen 3.Thus, can improve the left and right directions pushing precision of the processing cloth that keeps by lower platen 3 and top board 4 significantly, can further improve the quality of making finished product.
As previously mentioned, the sheet material that is not subjected to the lower platen 3 of left and right directions contact resistance effect can adopt the synthetic resin material of low rigidity to make.Thus, in the time of can reducing fore-and-aft direction and move and the contact resistance of move left and right plate 21, also can improve the pushing precision of processing cloth fore-and-aft direction.
Owing to effectively utilize the space of column 5 left and right sides on Sewing machines machine frame 7 tops to dispose a pair of fore-and-aft direction guide rail 43,43 and fore-and- aft direction arm 45,45, therefore, the integral width (left and right sides width) of pay-off F can be reduced, this pay-off F and pattern sewing machine M miniaturization can be made.
The left and right sides width that left and right sides width between the fore-and- aft direction arm 45,45 of pairing left and right has made the 1st moving area 22 that moves than left and right sides feeding table 23 is little.Thus, can will be located at the length setting of guide tang 46 of fore-and- aft direction arm 45,45 front ends in the left and right sides width of the 1st moving area 22, can not only prevent to cause the decline of fore-and-aft direction pushing precision because of the strain of guide tang 46, and can make guide tang 46 lightweights, can adapt to the high speed of fore-and-aft direction feeding speed.
The height and position of guide tang 46 can suitably be set.Thus, track component 47 along guide tang 46 can be carried out the mobile member 48 that left and right directions moves is fixed near the center of gravity of pressure arm 8, the fore-and-aft direction feeding power that front and back feed mechanism 40 is produced is delivered near the center of gravity of pressure arm 8, thereby can carry out the mobile feeding of fore-and-aft direction sleekly.
The leading section of the fore-and-aft direction guide rail 43,43 of pairing left and right is configured to bow and sees the form overlapping with the 1st moving area 22.Thus, can effectively utilize the space of the 1st moving area 22 tops, the fore-and-aft direction that reduces pay-off F takies length, thereby can make this pay-off F and pattern sewing machine M miniaturization.
The following describes the change form of the embodiment of above explanation having been carried out the locality change.
