As shown in Figure 4, on throughput direction (arrow A direction) front side and rear side of zipper teeth chain 14, a pair deflector roll (guide roller) 8,9 for making zipper teeth chain 14 carry on pedestal 1 is respectively arranged with across pedestal 1.In addition, in the following description, the direction that zipper teeth chain 14 advances to throughput direction A is expressed as " front (or throughput direction front) ", is expressed as to the direction of advancing with throughput direction opposite side at " rear (or throughput direction rear) ".
As shown in Figure 6, cutting portion 2 possesses opposed facing a pair point of a knife 21 in front end.As shown in Figure 4, point of a knife 21 extends abreast with the long side direction of zipper teeth chain 14.Cutting portion 2 declines on pedestal 1, cuts off the chain tooth 13 of zipper teeth chain 14.Cutting portion 2 is arranged at its top and the press ram (press ram) (not shown) be connected with cutting portion 2 drives, and can be elevated on pedestal 1.
The groove 22 tilted relative to the upper surface of pedestal 1 is formed in the inside of cutting portion 2.Bar-shaped detent mechanism 3 is contained in this groove 22, with the lifting linkage of cutting portion 2 be elevated on pedestal 1.Detent mechanism 3 can move along this groove 22.Detent mechanism 3, to become top and be positioned at the front side of throughput direction A and bottom becomes the mode of the state of the rear side of throughput direction A, configures obliquely relative to the upper surface of pedestal 1.Detent mechanism 3 at one end has the claw 31 that front end is formed thinner.According to Fig. 4 and Fig. 5, claw 31 is given prominence to downwards than the point of a knife 21 of cutting portion 2.
As shown in Figure 4, detent mechanism 3 with the end of claw 31 opposite side on be connected with force application mechanism 4 for exerting a force to detent mechanism 3.Force application mechanism 4 pairs of detent mechanisms 3 exert a force along groove 22 from throughput direction front below the geosyncline of rear.By this force oliquely downward, a detent mechanism 3 makes claw 31 be embedded between adjacent chain tooth 13 and chain tooth 13.Cutting portion 2 moves downwards further, and detent mechanism 3 relatively moves along above-mentioned groove 22 obliquely upward relative to cutting portion 2 thus.By this movement obliquely upward, be embedded into the claw 31 between chain tooth and engage with the chain tooth 13 of throughput direction front side, can carry out the location of zipper teeth chain 14 to throughput direction A side (throughput direction front) tractive (traction).That is, zipper teeth chain 14 from by the position before detent mechanism 3 tractive by the direction tractive close to cutting portion 2.Thereby, it is possible to make the chain tooth 13 that should carry out cutting off be positioned below the point of a knife 21 of cutting portion 2.Throughput direction A side refers to towards the direction in throughput direction front, with the position of the chain tooth 13 before carrying, claw 31 for benchmark, more will be called throughput direction A side by throughput direction front side than this benchmark.Describe the action of location below in detail.
As force application mechanism 4, if the device that can switch the force/force releasing to detent mechanism 3 does not then limit especially.In the present embodiment, such as preferably cylinder is used.As force application mechanism 4, adopt the device that can switch the force/force releasing to detent mechanism 3 as cylinder etc., the releasing that can control the force of detent mechanism 3 and the force to detent mechanism 3 according to the lifting action of cutting portion 2 thus.Therefore, compared with the situation in the past using spring to exert a force to detent mechanism 3 all the time like that, can not apply unwanted power to zipper teeth chain 14, therefore the position of zipper teeth chain 14 is departed from and is inhibited.
Force application mechanism 4 is connected with the force control mechanism 5 for controlling force application mechanism 4.Force control mechanism 5 controls force application mechanism 4 based on the action of cutting portion 2 and detent mechanism 3.Such as, when cutting portion 2 declines on pedestal 1, force control mechanism 5 makes force application mechanism 4 be in force state.When cutting portion 2 rises on pedestal 1, force control mechanism 5 makes force application mechanism 4 be in force disarm state.
Such as when adopting cylinder as force application mechanism 4, when cutting portion 2 declines on pedestal 1, force control mechanism 5 exports the signal be used for cylinder air supply to detent mechanism force.When cutting portion 2 rises on pedestal 1, force control mechanism 5 exports for making to stop the air supply of cylinder and removes the signal to the force of detent mechanism 3.The concrete mode of force control mechanism 5 is not particularly limited.Such as, also 5 groups, force control mechanism can be entered in the arithmetic control circuit (not shown) being used for controlling the action of cutting portion 2, drift 6 and punch die 7 each mechanism of forming apparatus 100 at equal intervals.
As shown in Figure 5, in the central area clamped by a pair cutting portion 2, drift 6 is configured with.In the mode relative with drift 6, in the space being formed at pedestal 1 center, be configured with punch die 7.Drift 6 and punch die 7 can in the oscilaltions of pedestal 1.To clamp and under the state keeping the residual part of chain tooth 13 at use drift 6 and punch die 7, residual part is moved to the below of pedestal 1, reliably can remove the cut-off residual part of chain tooth 13 thus from zipper teeth chain 14, thus interval S can be formed more reliably on zipper teeth chain 14.
-gap-forming method-
Use Fig. 4, Fig. 7 ~ Figure 13 illustrates the gap-forming method involved by embodiments of the present invention.First, by the deflector roll 8,9 shown in Fig. 4, the zipper teeth chain 14 shown in Fig. 2 is carried on pedestal 1.When by not shown position detector zipper teeth chain 14 being configured at the suitable position on pedestal 1, the press ram (not shown) be connected with cutting portion 2 declines, and the cutting portion 2 be connected with press ram and detent mechanism 3 decline on zipper teeth chain 14.As shown in Figure 7, the claw 31 being positioned at detent mechanism 3 front end is positioned at the point of a knife position more on the lower than cutting portion 2, and therefore claw 31 is more first than cutting portion 2 contacts with chain tooth 13.
After claw 31 contacts with chain tooth 13, by the further decline of cutting portion 2, as shown in Figure 8, claw 31 is embedded between adjacent chain tooth 13a and chain tooth 13b.When cutting portion 2 declines further, the claw 31 on the position represented with dotted portion of Fig. 9 is in position relationship at Fig. 9 between represented by dashed line and cutting portion 2, the active force be applied in for being embedded between chain tooth 13a and chain tooth 13b by force application mechanism 4, claw 31 is under the state be biased, dragged to throughput direction A layback by chain tooth 13a and chain tooth 13b, the bar-like portion of detent mechanism 3 is along groove 22 (the arrow B direction of Fig. 9) slip obliquely upward simultaneously.Thus, by the claw 31 of detent mechanism 3, carry out the location of zipper teeth chain 14 to throughput direction A side tractive (traction).Consequently, as shown in the solid line of Fig. 9, when the point of a knife 21 of cutting portion 2 contacts with chain tooth 13c, cutting portion 2 is adjusted to the appropriate location on zipper teeth chain 14.
Gap-forming device 100 involved according to the embodiment of the present invention, detent mechanism 3 moves in the limited space of groove 22, thus zipper teeth chain 14 is navigated to suitable position.Cut off and defect thereby, it is possible to prevent the chain tooth 13a of the non-severed object adjacent with becoming the chain tooth 13c that cuts off object from departing from cut-off portion 2 because of position.
After the point of a knife 21 of cutting portion 2 contacts with chain tooth 13, as shown in Figure 10, apply authorized pressure downwards from point of a knife 21, make a part 134 (being equivalent to the leg 133 of Fig. 1) for chain tooth 13 cut off and disperse thus.After the cut, force control mechanism 5 removes the force state of force application mechanism 4 pairs of detent mechanisms 3.Then, as is illustrated by figs. 11 and 12, cutting portion 2 and detent mechanism 3 is made again to increase to the top of pedestal 1.In addition, when detent mechanism 3 maintains the state be biased as in the past, due to the rising of cutting portion 2, the claw 31 of detent mechanism 3 can make chain tooth 13a, 13b move to the throughput direction rear of zipper teeth chain 14.But, detent mechanism 3 involved by embodiments of the present invention is in force application mechanism 4 force downwards by the state removed, therefore as shown in figure 11, with the rising of cutting portion 2 linkedly, rise from final position location (dotted portion) directly to top.
As shown in figure 13, between a pair point of a knife 21 of cutting portion 2, drift 6 is declined on chain tooth 13, by the residual part (be equivalent to engageable head 131 and the main part 132 of Fig. 1) of drift 6 with punch die 7 clamping chain tooth 13, and its below to pedestal 1 is released.Thus, from zipper teeth chain 14, reliably remove chain tooth 13, produce the zipper teeth chain 14 as shown in figure 3 with interval S.
Gap-forming device 100 involved according to the embodiment of the present invention and employ the gap-forming method of this gap-forming device 100, by force application mechanism 4 and the force control mechanism 5 for controlling force application mechanism 4, when detent mechanism 3 rises, remove the force of force application mechanism 4 pairs of detent mechanisms 3.Thus, detent mechanism 3 force is downwards removed, and therefore when the detent mechanism 3 be embedded between chain tooth 13 together rises with cutting portion 2, chain tooth 13 can not be pulled to throughput direction rear.Consequently, the position of zipper teeth chain 14 can be suppressed to depart from.By suppressing the position of zipper teeth chain 14 to be departed from, when utilizing drift 6 afterwards and punch die 7 removes the residual part of the chain tooth 13 after cutting off from zipper teeth chain 14, also can utilize the residual part of drift and punch die 7 suitably clamping chain tooth 13.Consequently, a kind of gap-forming device 100 reliably can removing the chain tooth 13 of fracture can be provided.And, gap-forming device 100 involved by embodiments of the present invention can use a detent mechanism 3 by zipper teeth chain 14 to suitable position traction (location), therefore, it is possible to reduce the number of components for locating, thus a kind of gap-forming device with simpler structure can be provided.
