As shown in Fig. 4 (a), drive gear 29 is engaged with the crank part 25 being formed as gear.Drive gear 29 Rotation rotates in the opposite direction crank part 25, around rotation axiss 26a, makes the change in location of crank axle 25a.Crank axle 25a Jing Engaging bar 25b is engaged with the slot 27a of arm member 27.Because slot 27a extends in the footpath direction of angular displacement axis 23a, So, on the footpath direction, engaging bar 25b is slided when being engaged with slot 27a.If crank part 25 is around rotation axiss 26a is rotated in one direction, then 27 Jing crank axle 25a of arm member, engaging bar 25b and slot 27a swing, so as to around angular displacement Axis 23a is repeated reversion.

For example, if making drive gear 29 rotate in the counterclockwise direction from the state of Fig. 4 (a), crank part 25 is in up time Pin direction rotates, Jing crank axle 25a, makes engaging bar 25b slide to the interior side in footpath direction in slot 27a, and arm member 27 exists Counterclockwise swing.After slider bar 25b reaches the most interior side in footpath direction in sliding groove 27a, glide direction is reversed to footpath The foreign side in direction, but, arm member 27 continues anticlockwise swing.With regard to engaging bar 25b and card as shown in Fig. 4 (b) For closing the engaging position of groove 27a, until it becomes footpath direction relative to angular displacement axis 23a and relative to rotation axiss 26a The orthogonal state in footpath direction till, arm member 27 is swung in the counterclockwise direction.

If from the state shown in Fig. 4 (b), continuing the anticlockwise rotation of drive gear 29, then by crank portion The clockwise rotation of part 25, engages bar 25b and continues to the foreign side in footpath direction to slide in slot 27a, but, arm The swaying direction reversion of part 27.If making drive gear 29 further rotate in the counterclockwise direction, crank part 25 is clockwise Direction continues rotation, engages bar 25b and slides to the foreign side in footpath direction in slot 27a, after most foreign side is reached, carries out anti- Turn to slide to the interior side in footpath direction.With regard to the engaging bar 25b and slot 27a as shown in Fig. 4 (c) engaging position and Speech, if becoming relative to the footpath direction of angular displacement axis 23a and relative to the orthogonal state in the footpath direction of rotation axiss 26a, The swaying direction reversion of arm member 27.

Arm member 27 is swung in the clockwise direction from the state shown in Fig. 4 (b) to Fig. 4 (c).In addition, arm member 27 exists From the state shown in Fig. 4 (c) to Fig. 4 (b), swing in the counterclockwise direction.That is, Fig. 4 (b) and state shown in Fig. 4 (c) become by The stop of the crank mechanism that crank part 25 and arm member 27 are formed, unidirectional rotation of crank part 25 are converted into stop Between arm member 27 swing repeatedly.By the swing repeatedly of arm member 27, pin support shaft 23 makes pre- around angular displacement axis 23a Reversion in the range of fixed angle is repeated, and the pecker 11 for being maintained at the bottom of pin support shaft 23 also makes reversion repeatedly Carry out.

In the reversing device 18 of the present embodiment, for example, motor 17 can be made to rotate in one direction, is inverted at about 50 degree Angle in the range of be repeated angular displacement.In the case where alternately direction of rotation is switched using servo motor, can only Rotating speed is lifted to the low rotating speed of the situation than rotating in one direction.In the present embodiment, as long as making motor 17 revolve in one direction Turn, can proceed to high-revolving rotation.Because pecker 11 is by reversing device 18 around angular displacement axis 23a predetermined It is repeated reversion in the range of angle, so, penetrating property becomes good, it is not necessary to reduces the stacking thickness of fine sheet 7, can enter The stable piercing of row, will not also produce the undesirable condition caused because of the winding of line 9.Further, because the rotation of motor 17 is only utilized One direction, so, if using one-way clutch in the lump, the rotation of other direction can be used to not use the piercing drill of line 9 Or bore a hole for the line using different lines 9.

In addition, in reversing device 18, because rotation is converted to swing by crank part 25 and arm member 27, By the adjustment of the distance between the offset of crank axle 25a, rotation axiss 26a and angular displacement axis 23a etc., pendulum can be adjusted Dynamic angular range.In addition, though crank part 25 and arm member 27 are combined, but it is also possible to utilize the machines such as cam, connecting rod Structure, from rotation to swing conversion.In addition, though via the drive gear 29 driven with drive shaft 22 come rotation driving crank part 25, but it is also possible to by 22 direct rotation driving crank part 25 of drive shaft.But, in this case it is necessary to be adjusted to arm Part 27 does not disturb drive shaft 22.In the present embodiment, although crank part 25 is made gear, make to engage with drive gear 29 Gear ratio be 1:1, but, if change gear ratio, can be with speedup or deceleration.

Fig. 5 represents the shape near the front end of pecker 11.Pecker 11 is extended along angular displacement axis 23a, to front end 11a arranges the tubulose of hollow part 11b till nearby.Front end 11a is formed tapered, near the 11a of front end, in the sky of tubulose The side of center portion 11b formed line 9 by hole 11c.Although also can be cut with being inclined by using front end 11a as pecker 11 The pin of such knife-edge shape, but, for knife-edge shape when, especially in the case of the fine sheet 7 of the thin knitted fabric of coil, exist The probability line of cloth cut off when being pierced into.Further, since front end is from axis misalignment, so, exist and piercing to fine sheet 7 In fashionable, piercing, warpage, the problem of bending are produced, existence position precision is reduced, the probability that pin is damaged.The present embodiment is worn Hole pin 11 is formed tapered because of the front end 11a extended along angular displacement axis 23a, around angular displacement axis 23a predetermined It is repeated high speed reverse rotation in the range of angle, thus it is possible to when being pierced into fine sheet 7, easily fiber is pushed open by one side Simultaneously it is pierced between fiber, it is difficult to damaged fiber.

In the above embodiments, although line punching machine 10 is arranged on into the severing 3 of cutting machine 1, however, it is also possible to Line punching machine 10 is used together or is used alone in the same manner as patent documentation 1 with stretching machine etc..
