(action specification of embodiment)
Below, the action of Sewing machines with said structure is described.
At first, make in the process, the connecting rod front end 6a of cylinder 6 is outstanding to arrow B 1 direction, and cylinder union body 7 is configured in initial position shown in Figure 4.Therefore, become and cut off cutting knife 2 and movable cutting knife 9 to be configured in simultaneously that giving up the throne at last of arrow B 2 directions put be state (with reference to Fig. 9) on the initial position.
Then, if by the depressing backward of not shown Sewing machines pedal, cut off the line signal to control part (diagram slightly) input, then to cylinder 6 injecting gas, connecting rod front end 6a moves to arrow A 1 direction.Thus, as shown in Figure 5, cylinder union body 7 moves to arrow A 1 direction, via cutter driving wrist 5 and cut-out slitter shaft 4, cuts off cutting knife platform 3 and rotates (with reference to Fig. 2) to arrow A 2 directions.And in the moment that described Sewing machines pedal is depressed backward, sewing machine electromotor begins rotation.
Rotate to arrow A 2 directions if cut off cutting knife platform 3, then described cut-out cutting knife platform 3 engages with the movable cutter driving pin 21 of the lower surface that is fixed on movable cutting knife platform 10, and movable thus cutting knife platform 10 also rotates to the direction of arrow A 2.Turn to the line off-position by cutting off cutting knife 2 to arrow A 2 directions, via movable cutting knife platform 10 and movable slitter shaft 11, movable cutter driving wrist 12 rotates to arrow A shown in Figure 23 directions, become the state that cam roller 13 engages with the interval 15a of the standby of tangential cam 15, cutting off cutting knife platform 3 becomes the state that rotation temporarily stops.
In the process that cam roller 13 moves along the interval 15a of the standby of the tangential cam 15 shown in Fig. 8 (a)～(c), movable cutting knife 9 and cut-out cutting knife 2 are near the state (with reference to Figure 10) of standby needle downing position, as shown in figure 14, outer still 22 hooks at its tip reaches the standard grade T1 and after making the T1 that reaches the standard grade form triangle, shown in Fig. 8 (d), during to the pulling amount of reaching the standard grade, cam roller 13 is by the maximal end point of the interval 15a of standby at still.Then, by along the interval 15b drive cam of groove roller 13, movable cutter driving wrist 12 is to the swing of arrow A 3 directions, and movable cutting knife 9 is advanced further to the direction of arrow A 2.And,, then cut off 3 beginnings of cutting knife platform and rotate once more if cam roller 13 guides to the interval 15b of the groove shown in Fig. 8 (d) from the interval 15a of the standby shown in Fig. 8 (a)～(c).And if end at caging bolt 27 that cuts off installation on the cutting knife platform 3 and limiting plate 28 cards, the rotation of then cutting off cutting knife platform 3 is restricted, and cuts off cutting knife 2 and is configured in (with reference to Figure 10) on the suture off-position.Under this state, become near the pin center 32 that falls that extends to needle plate 25 belows state (with reference to Figure 12) as the point of a knife 2a of the front end that cuts off cutting knife 2.
At this moment, the front end of movable cutting knife 9 such as Figure 10～Figure 12 and shown in Figure 14 moving and insert in the triangle of the T1 that reaches the standard grade are so that it passes the space 33 than the below of the needle plate 25 of more close pin center 32 1 sides that fall of middle still jut 23a and middle still guide portion 25a and feeding tooth 26.
If tangential cam 15 continues rotation, cam roller 13 moves to the progressive position of movable cutting knife shown in Fig. 8 (e), and then movable cutting knife 9 is back to the line catching position of stepping back certain distance than progressive position shown in Figure 11.
Then, utilize the interval 15b of groove and the moving direction of movable cutter driving wrist 12 to the counter-rotating of arrow B 3 directions, catch roll off the production line T1, T2 (with reference to Figure 17 and Figure 22) by the line capture unit 9d of the movable cutting knife 9 that retreats to arrow B 2 directions.
At this moment, at the outer circumferential side of movable cutting knife 9, as shown in figure 23, become the state on the 31a of hanging wire portion that reach the standard grade T1 and the T2 that rolls off the production line be hooked on cable guiding device 31.And the interior all sides at movable cutting knife 9 as Figure 17 and shown in Figure 22, become the T1 that reaches the standard grade and keep out of the way the state of dodging the 9a of portion to reaching the standard grade of movable cutting knife 9.
If tangential cam 15 continues rotation, cam roller 13 is directed to the line off-position shown in Fig. 8 (f), and then movable cutting knife 9 retreats to line off-position (with reference to Figure 16).Then, after the hook line 29b of portion of the clamped spring 29 of the T2 that rolls off the production line hooked, by point of a knife 2a and the movably co-operating of the blade 9c of cutting knife 9 of cutting off cutting knife 2, the reach the standard grade T1 and the T2 that rolls off the production line were cut off (with reference to Figure 18).And cam roller 13 passes the open space 15c of tangential cam 15, is released in the periphery of described tangential cam 15, is disengaged (with reference to Fig. 8 (g)) with interval the engaging of 15b of groove.
Here, as shown in figure 12, the blade 9c of movable cutting knife 9 passes pin center 32 and rotates, point of a knife 2a standby near near the of the described pin center 32 that falls.Therefore, by movable cutting knife 9 with the co-operating of cutting off cutting knife 2 suture T1, when T2 is cut off, pin center 32 to the distance of point of a knife 2a significantly shortens than prior art from falling.
And after the reach the standard grade T1 and the T2 that rolls off the production line were cut off, as shown in figure 19, the T1 that reaches the standard grade dodged the 9a of portion and extracts and become free state from reaching the standard grade, the T2 that the rolls off the production line clamping section 29a clamping of being rolled off the production line.
In addition, as shown in figure 16, if movable cutting knife 9 then stops sewing machine electromotor by control part by the suture off-position, suture needle 24 stops at upper position (going up stop position).Meanwhile, from control part output tangent line reset signal, the connecting rod front end 6a of cylinder 6 moves to arrow B 1 direction corresponding to described output signal.Thus, cut off cutting knife 2 and reset to initial position shown in Figure 9 with movable cutting knife 3.At this moment, as shown in Figure 8, the interval 15b of the groove of tangential cam 15 is until the cut-out end position of the reach the standard grade T1 and the T2 that rolls off the production line, because after described cut-out, when suture needle 24 stops on the stop position, cam roller 13 moves to 15c between the open zone, therefore when movable cutting knife 3 resets to initial position, can not hinder the action of this movable cutting knife 3.
(effect of embodiment)
As mentioned above, according to the Sewing machines of present embodiment, because movable cutting knife 9, its front end can pass through than more close needle downing position 32 1 sides of the periphery of middle still 23, so the line off-position can be than prior art more near needle downing position 32 sides.Thus, can use existing in still guide portion and the needle plate, the residual end length of residual line on the shortening sewn object.Thereby, can shorten the time that post-processed such as plucking line needs, can realize the raising of production efficiency.
In addition, because movable cutting knife 9 is dodged above middle still 23 in its whole shift action process, the upper surface of still 23 approaches near the needle plate 24 in therefore can making.Thus, the line amount of the T2 that rolls off the production line that reels on the bobbin in the still 23 in being installed on is increased, can reduce the number of times of changing bobbin, thereby can realize the raising of production efficiency.
In addition, because by driving a cylinder 6, can realize making and cut off the action that cutting knife 2 and movable cutting knife 9 rotate and make in the action of this movable cutting knife 9 and last axle interlock any one, therefore can suppress the number of parts, realize the inhibition of cost.
