The specific embodiment
Below, utilize Fig. 1～Fig. 4 that the knitted fabric preforming device 1 as one embodiment of the invention is described.In the explanation of each figure,, put down in writing this not shown mentioning sometimes with reference to label to the part of explaining earlier.
[embodiment]
Fig. 1 will represent with the state that is not equipped on cam carrier as the formation of the knitted fabric preforming device 1 of one embodiment of the invention.Knitted fabric preforming device 1 comprises organizes compressing tablet 2, swing mechanism 3, stepping motor 4, revolving member 5 and sensor 6.Be equipped at knitted fabric preforming device 1 under the state of cam carrier of straight-bar machines, organize the pressure rod 2a of the front end of compressing tablet 2 to be in direction in the face of the tooth mouth of straight-bar machines.Swing mechanism 3 makes organizes compressing tablet 2 to swing with respect to the mode of tooth mouth advance and retreat with pressure rod 2a.Stepping motor 4 is via swing mechanism 3 driven organization compressing tablets 2.Revolving member 5 is installed on the output shaft 4a of stepping motor 4.Sensor 6 disposes near stepping motor 4.For to organizing compressing tablet 2, be provided with stiff spring 7 to the direction application of force of retreating from the tooth mouth.
Stepping motor 4 is with respect to body, also has output shaft 4b at the opposition side of output shaft 4a.The bristle 8 that output shaft 4b representes to simplification and with imaginary line so that its mode via driving and reversing mechanism 9 advance and retreat drive.Bristle 8 is opened needle latch under being used for when using latch needles as knitting needle, getting the hang of.The swing mechanism 3 and the stepping motor 4 of knitted fabric preforming device 1 are installed on carriage 10.Sensor 6 is installed on carriage 10 via installation component.Driving and reversing mechanism 9 is installed on base portion 11.Base portion 11 is installed on stepping motor 4 and carriage 10.
The operating state of the knitted fabric preforming device 1 of Fig. 2 presentation graphs 1, but omitted stiff spring 7.(a) represent the state that pressure rod 2a retreats, (b) state of expression pressure rod 2a entering.Revolving member 5 is installed on the output shaft 4a of stepping motor 4, has the side of retreating respectively and detects projection 5a, approaching side detection projection 5b and crank arm 5c.Swing mechanism 3 has erecting bed 12, toggle-action lever 13 and the connecting rod 14,15 of organizing compressing tablet 2.One end of toggle-action lever 13 is linked to the crank arm 5c of revolving member 5, and the other end is linked to the quadric chain that is formed by erecting bed 12 and connecting rod 14,15 at the linking portion of erecting bed 12 and connecting rod 14.When the output shaft 4a of stepping motor 4 rotated, the erecting bed 12 via crank arm 5c, toggle-action lever 13 and the quadric chain of revolving member 5 made and organizes compressing tablet 2 swings.
Shown in Fig. 2 (a), under the state that pressure rod 2a retreats, form the crank arm 5c utilize revolving member 5, toggle-action lever 13 with the linking portion of erecting bed 12 and connecting rod 14 to the state of pushing away from the direction of output shaft 4a.The side detection projection 5a that retreats of revolving member 5 faces the test section 6a of sensor 6 and detects this state.The output shaft 4a of stepping motor 4 becomes getting the hang of of the pressure rod 2a shown in Fig. 2 (b) when counterclockwise rotating about half-turn.Toggle-action lever 13 becomes the crank arm 5c that is rotated member 5 to be introduced to the direction near output shaft 4a, and with the linking portion of erecting bed 12 and connecting rod 14 to the state of introducing near the direction of output shaft 4a.The approaching side of revolving member 5 detects projection 5b and detects this state in the face of the test section 6a of sensor 6.
Because drive source uses stepping motor 4, therefore can carry out the high driving of reliability for direction of rotation or the angle of output shaft 4a, utilize a sensor 6 to detect also and can improve reliability.Because a sensor 6 is set to get final product, therefore cost be can reduce, and the lightweight and the miniaturization of the knitted fabric preforming device 1 that cam carrier carried realized, can also reduce the driving load of cam carrier.Though also can with revolving member 5 retreat that side detects projection 5a and approaching side detects the part of projection 5b and the part split setting of crank arm 5c, integrated through carrying out, can guarantee the reliability of the reduction and the action of number of components.
The formation of the revolving member 5 that uses in the knitted fabric preforming device 1 of Fig. 3 presentation graphs 1.(a) reaching (b) is respectively left side view and the front view as revolving member 5.The direction of observing as the front view of Fig. 3 (b) is suitable with the direction of observing as the left side view of Fig. 2.Revolving member 5 is provided with the axis hole 5d of the output shaft 4a that is used to be installed on stepping motor 4, also is provided with to be used in screw hole 5e, the 5f that hold-down screw that installment state is fixed screws togather.Front end at crank arm 5c also is provided with the connect apertures 5g that is used for toggle-action lever 13 bindings.
Fig. 4 will arrange the formation reduced representation of the driving and reversing mechanism 9 of the bristle 8 that is provided with on the knitted fabric preforming device 1 of Fig. 1.Bristle 8 is installed on adjustment platform 20, and adjustment platform 20 is advanced and retreat along the linking portion between the end of end of arm 21 and connecting rod 22.The other end of arm 21 combines with carriage 10 through pin.The rotation that the driving utilization that makes bristle 8 advance and retreat is transmitted to driven gear 24 from the driven wheel 23 of the output shaft 4b that is installed on stepping motor 4 and carrying out.The other end of connecting rod 22 is linked to driven gear 24 at the eccentric position from misalignment.The gear ratio of driven wheel 23 and driven gear 24 is set to 2:1, and output shaft 4b rotates about half cycle, 24 about weeks of rotation of driven gear.Set through this, can through knitted fabric preforming device 1 pressure rod 2a is got into or retreat during bristle 8 is back and forth advanced and retreat.
