The support shaft 33a supporting the 1 st driven roller 33 is formed as an eccentric shaft, and a portion supporting the 1 st driven roller 33 is eccentric with respect to a portion supported by the 1 st end 32A of the lever 32. Accordingly, the position of the 1 st driven roller 33 can be changed by simply rotating the support shaft 33a with respect to the lever 32, and therefore, the contact between the 1 st driven roller 33 and the reverse cam 81 of the drive shaft 80 can be easily adjusted.
The support shaft 34a supporting the 2 nd driven roller 34 is formed as an eccentric shaft, and a portion supporting the 2 nd driven roller 34 is eccentric with respect to a portion supported by the 2 nd end 32B of the lever 32. Accordingly, the position of the 2 nd driven roller 34 can be changed by simply rotating the support shaft 34a with respect to the lever 32, and therefore, the contact between the 2 nd driven roller 34 and the forward cam 82 of the drive shaft 80 can be easily adjusted.
In the cutting section 20 and the 1 st hammer drive mechanism 30 configured as described above, the drive shaft 80 rotates and the cam top of the retraction cam 81 presses the 1 st driven roller 33 downward, whereby the lever 32 rotates clockwise in fig. 6 and the 1 st hammer 21 retracts. Further, the drive shaft 80 rotates and the cam top of the forward cam 82 presses the 2 nd driven roller 34 rearward, whereby the lever 32 rotates counterclockwise in fig. 6 and the 1 st hammer 21 advances. Therefore, the 1 st hammer 21 reciprocates in the front-rear direction by the rotation of the drive shaft 80.
As shown in fig. 10 to 13, the 2 nd hammer drive mechanism 50 includes: a base part 51 fixed to an apparatus frame not shown; a lever 52 rotatably provided on the base portion 51 and having a 1 st end portion 52A to a 3 rd end portion 52C; a pair of 1 st driven rollers 53 rotatably provided at the 1 st end 52A of the lever 52; a pair of 2 nd driven rollers 54 rotatably provided at the 2 nd end portion 52B of the lever 52; and a link 55 having one end rotatably coupled to the 3 rd end portion 52C of the lever 52 and the other end rotatably coupled to the upper end portion of the 2 nd hammer 41. Also, the pair of 1 st driven rollers 53 are respectively in contact with the pair of downward moving cams 83 of the drive shaft 80. In addition, the pair of 2 nd driven rollers 54 are respectively in contact with the pair of upward moving cams 84 of the drive shaft 80.
The lever 52 is rotatably supported by the base portion 51 via a support shaft 51 a. The pair of 1 st driven rollers 53 are supported rotatably with respect to the 1 st end 52A of the lever 52 by a support shaft 53 a. The pair of 2 nd driven rollers 54 are supported rotatably with respect to the 2 nd end portion 52B of the lever 52 by a support shaft 54 a. One end of the link 55 is rotatably coupled to the 3 rd end portion 52C of the lever 52 by a lever-side coupling shaft 55a, and the other end of the link 55 is rotatably coupled to the 2 nd hammer 41 by a hammer-side coupling shaft 55 b.
The support shaft 53a supporting the 1 st driven roller 53 is formed as an eccentric shaft, and a portion supporting the 1 st driven roller 53 is eccentric with respect to a portion supported by the 1 st end 52A of the lever 52. Therefore, the contact condition of the 1 st driven roller 53 with the downward movement cam 83 of the drive shaft 80 can be adjusted.
The support shaft 54a supporting the 2 nd driven roller 54 is formed as an eccentric shaft, and a portion supporting the 2 nd driven roller 54 is eccentric with respect to a portion supported by the 2 nd end 52B of the lever 52. Therefore, the contact condition of the 2 nd driven roller 54 with the upward moving cam 84 of the drive shaft 80 can be adjusted.
In the head forming portion 40 and the 2 nd hammer driving mechanism 50 configured as described above, the drive shaft 80 rotates and the cam top portion of the downward movement cam 83 presses the 1 st driven roller 53 upward, whereby the lever 52 rotates in the clockwise direction in fig. 13 and the 2 nd hammer 41 moves downward. In addition, the drive shaft 80 rotates and the cam top of the upward moving cam 84 presses the 2 nd driven roller 54 forward, whereby the lever 52 rotates counterclockwise in fig. 13 and the 2 nd hammer 41 moves upward. Therefore, the 2 nd hammer 41 reciprocates in the up-down direction by the rotation of the drive shaft 80.
As shown in fig. 3 to 7, the 1 st hammer 21 is mounted at its front end portion with a lower die holder (dieholder)25 holding the cutting die 22.
As shown in fig. 7 and 14, the cutting die 22 includes a spacer 27 attached to the lower die holder 25, and a die body 28 attached to a front surface of the spacer 27. A penetration groove 27a is formed in the vertical direction on the front surface of the spacer 27, and the penetration groove 27a constitutes a half of the penetration hole 22a through which the wire rod W penetrates. A cut groove 28a is formed in the vertical direction on the rear surface of the die main body 28, and the cut groove 28a constitutes a half of the insertion hole 22a through which the wire rod W is inserted (see fig. 16). The insertion hole 22a is formed by aligning the insertion groove 27a of the spacer 27 and the cut groove 28a of the die body 28 in the front-rear direction. The cut groove 28a is formed in the same shape as the outer peripheral surface of the fastener element E on the pair of leg portions E2 side.
As shown in fig. 15 and 16, the mold body 28 is a block-shaped member having a substantially square shape in front view, and has a front surface 90, a rear surface 91, and four side surfaces 92. Two cuts 28a are formed orthogonally on the rear surface 91 of the mold body 28, and the end portions of the cuts 28a are open on the four side surfaces 92. The four side surfaces 92 are formed with molding recesses 43a of the molding die 43, which will be described later.
Two suction holes 28b for sucking chips and the like generated when the wire rod W is cut by the cutting groove 28a are formed in the die main body 28 so as to be orthogonal to each other, and the end portions of the suction holes 28b are opened at the four side surfaces 92. The opening of each suction hole 28b is disposed between the cutting groove 28a of each side surface 92 and the forming recessed portion 43 a. In addition, a communication hole 28c that communicates the two intersecting cutting grooves 28a with the two intersecting suction holes 28b is formed in the center portion of the rear surface 91 of the die main body 28. Therefore, the chips and the like can be sucked from the notch groove 28 a. In addition, two tape accommodating grooves 28d for accommodating the fastener tapes T when the 1 st ram 21 advances are formed orthogonally in the front surface 90 of the die main body 28.
In the mold main body 28 configured as described above, a pair of the cutting grooves 28a, the forming recessed portion 43a, the suction holes 28b, and the tape accommodation grooves 28d are arranged on each of the four side surfaces 92. Therefore, when the cut groove 28a and the forming recessed portion 43a of one side surface 92 are worn or damaged, the die main body 28 is detached and the die main body 28 is attached again so that the other side surface 92 becomes the upper surface, and thus, a new cut groove 28a and a new forming recessed portion 43a can be used. That is, one mold body 28 can be used four times.
As shown in fig. 9, a fitting recess 25a is formed in the vertical direction at the front end of the lower die holder 25, and the cutting die 22 is fitted into the fitting recess 25a to position the cutting die 22 in the lateral direction. Therefore, the positioning of the spacer 27 of the cutting die 22 and the die main body 28 in the left-right direction is completed only by fitting the cutting die 22 into the fitting recess 25a of the lower die holder 25. Therefore, when the shim 27 and the die main body 28 are attached, it is not necessary to manually position the shim 27 and the die main body 28 in the left-right direction.
As shown in fig. 7 and 14, a fitting recess 27b is formed along the left-right direction on the rear surface of the spacer 27, and the spacer 27 is positioned in the vertical direction by fitting the fitting recess 27b to the front end of the lower die holder 25. Therefore, the positioning of the spacer 27 in the vertical direction is completed only by fitting the fitting recess 27b of the spacer 27 to the front end portion of the lower die holder 25. Therefore, when the spacer 27 is attached, it is not necessary to manually position the spacer 27 in the vertical direction.
As shown in fig. 4 and 7, a shim fixing member 26 is attached to a lower portion of a front end surface of the die holder 25, and the shim fixing member 26 presses and fixes a shim 27 of the cutting die 22 to the die holder 25. A table portion 26a is formed in the center portion of the upper surface of the pad fixing member 26, and the mold main body 28 of the cutting die 22 is placed on the table portion 26a, whereby the mold main body 28 is positioned in the vertical direction. Therefore, the positioning of the mold main body 28 in the vertical direction is completed only by placing the mold main body 28 on the table portion 26 a. Therefore, when the mold body 28 is mounted, it is not necessary to manually position the mold body 28 in the vertical direction.
As shown in fig. 4 and 7, a pair of die fixing members 29 are attached to an upper portion of a front end surface of the lower die base 25, and the die fixing members 29 press and fix the die main body 28 of the cutting die 22 to the shim 27. Therefore, the die main body 28 having a high wear rate can be easily replaced by simply detaching the pair of die fixing members 29 from the lower die base 25.
As shown in fig. 13, the cutting punch 23 is attached to the front surface of the lower end portion of the hammer guide 45 of the head forming portion 40. The cutting punch 23 is disposed such that the lower surface thereof is in sliding contact with the upper surface of the cutting die 22. Further, a cutting recess 23a having the same shape as the outer peripheral surface of the fastener element E on the coupling head E1 side is formed at the tip end portion of the cutting punch 23.
As shown in fig. 10, 11, and 13, an upper die holder 41a holding a forming punch 42 is attached to a front surface of a lower end portion of the 2 nd hammer 41. A pad holder 41b to which the element pressure pad 44 is attached to the front surface of the upper die base 41 a. The element pressure pad 44 is provided between the upper die base 41a and the pad holder 41b so as to be slidable in the vertical direction.
As shown in fig. 7 and 9, the molding die 43 is formed integrally with the die body 28 of the cutting die 22, and a molding recess 43a into which the coupling head E1 of the fastener element E is fitted is formed at the distal end portion of the molding die 43. Further, as described above, the forming dented portions 43a are formed on the four side surfaces 92 of the mold main body 28, respectively.
As shown in fig. 13, the 2 nd hammer driving mechanism 50 is provided with a pad pressing mechanism 56 that presses the element pressing pad 44 downward. The pad pressing mechanism 56 includes: a pressing pin 56a provided on the link 55 so as to be slidable in the vertical direction and abutting against the upper end surface of the element pad 44; a pair of compression springs 56b that press the pressing pins 56a downward; and a spring receiver 56c fixed to the upper surface of the link 55 and receiving the upper end portions of the pair of compression springs 56 b. The pressing pin 56a is inserted into a guide hole 55c formed along the longitudinal direction (vertical direction) of the link 55 at the center in the width direction of the link 55.
The pressing pin 56a is operated to absorb the dimension of upward movement of the element pressure pad 44 when the 2 nd hammer 41 moves downward and the element pressure pad 44 presses the fastener element E (see fig. 19).
In the element pressure pad 44 and the pad pressing mechanism 56 configured as described above, since the element pressure pad 44 is always pressed downward by the pad pressing mechanism 56, the following property of the element pressure pad 44 with respect to the vertical movement of the 2 nd hammer 41 at the time of high-speed driving can be improved, and thereby, high-speed operation of the fastener stringer manufacturing apparatus 10 can be realized. Further, since the fastener element E can be reliably pressed by the element pressing pad 44, the molding accuracy of the coupling head E1 of the fastener element E can be maintained constant.
As shown in fig. 3 to 5 and 8, the pressing portion 60 includes: a pair of pressing punches 61 provided on the upper surface of the lower die base 25 of the 1 st hammer 21, for pressing the pair of leg portions E2 of the fastener element E; a pair of chamfering punches 62 provided on the upper surface of the lower die base 25 of the 1 st ram 21 for chamfering the fastener elements E; and a pair of punch driving portions 70 that drive the pair of pressing punches 61 and the pair of chamfering punches 62.
The pair of pressing punches 61 and the pair of chamfering punches 62 are provided slidably in the left-right direction by a punch guide base 65 and a punch guide housing 66 (see fig. 6) attached to the upper surface of the lower die holder 25 of the 1 st ram 21. The punch guide housing 66 is formed to cover the upper portions of the press punch 61, the chamfering punch 62, and the punch guide base 65.
As shown in fig. 8 and 9, the pressing punch 61 includes: a recess 61a formed at an inner end of the pressing punch 61 and into which a leg E2 of the fastener element E is fitted; and a guided surface 61b formed at an outer end of the pressing punch 61 and configured to contact a guide surface 72a of a pressing punch guide 72, which will be described later, to advance the pressing punch 61 inward in the width direction. The guided surface 61b is a surface inclined so as to face forward. The pressing punch 61 is constantly biased outward in the width direction by a compression spring 61c disposed inside thereof.
As shown in fig. 8 and 9, the chamfering punch 62 includes: a concave chamfered portion 62a formed at an inner end of the chamfering punch 62 and chamfering a corner of the fastener element E; and a guided surface 62b formed at an outer end of the chamfering punch 62, and configured to move the chamfering punch 62 inward in the width direction by contacting a guide surface 73a of a chamfering punch guide 73, which will be described later. The guided surface 62b is a surface inclined so as to face forward. The chamfering punch 62 is constantly biased outward in the width direction by a compression spring 62c disposed inside thereof.
As shown in fig. 8, the chamfering punch 62 is disposed so as to overlap the pressing punch 61. The chamfering punch 62 is disposed along a direction orthogonal to the sliding direction of the 1 st hammer 21, and the pressing punch 61 is disposed obliquely to the chamfering punch 62. Therefore, the pressing punch 61 and the chamfering punch 62 are disposed so as to intersect with each other in the sliding direction.
As shown in fig. 5 and 8, the punch driving unit 70 is disposed outside the pressing punch 61 and the chamfering punch 62 in the width direction, and includes: a housing 71 fixed to an apparatus frame not shown; a pressing punch guide 72 disposed in the housing 71 and driving the pressing punch 61; a chamfering punch guide 73 disposed in the housing 71 and driving the chamfering punch 62; and a cover 74 closing an upper opening of the housing 71.
The pressing punch guide 72 is provided in the housing 71 so as to be slidable in the left-right direction and fixable at an arbitrary position. Further, a guide surface 72a is formed at an inner end portion of the pressing punch guide 72, and the guide surface 72a is brought into contact with the guided surface 61b of the pressing punch 61 when the 1 st hammer 21 advances.
The chamfering punch guide 73 is disposed adjacent to the front side of the pressing punch guide 72, and is provided in the housing 71 so as to be slidable in the left-right direction and fixable at an arbitrary position. Further, a guide surface 73a is formed at an inner end portion of the chamfering punch guide 73, and the guide surface 73a comes into contact with a guided surface 62b of the chamfering punch 62 when the 1 st hammer 21 advances.
In the pressing portion 60 configured as described above, the 1 st ram 21 advances, and the guided surfaces 61b of the left and right pressing punches 61 come into contact with the guide surfaces 72a of the left and right pressing punch guides 72, whereby the left and right pressing punches 61 advance inward in the width direction, and the pair of leg portions E2 of the fastener element E fitted in the concave portions 61a of the left and right pressing punches 61 are pressed, whereby the fastener element E is attached to the fastener tape T (see fig. 22).
Further, the 1 st hammer 21 advances and the guided surfaces 62b of the left and right chamfering punches 62 come into contact with the guide surfaces 73a of the left and right chamfering punch guides 73, whereby the left and right chamfering punches 62 advance inward in the width direction, and the corner portion of the fastener element Eb attached to the fastener tape T one before the fastener element Ea attached to the fastener tape T at present is chamfered by the chamfering portion 62a of the chamfering punch 62 (see fig. 23).
Next, the operation of the fastener stringer manufacturing apparatus 10 will be described with reference to fig. 17 to 23.
First, fig. 17 shows a state where the 1 st striker 21 has advanced and a fastener element E is attached to the fastener tape T. At this time, the wire W is supplied to the insertion hole 22a of the cutting die 22 by the wire supplying portion 100 by an amount corresponding to the thickness of the fastener element E, and the wire W protrudes on the cutting die 22 by an amount corresponding to the thickness of the fastener element E.
Next, as shown in fig. 18, the 1 st hammer 21 is retracted, and the wire W sandwiched between the insertion hole 22a of the cutting die 22 and the cutting recess 23a of the cutting punch 23 is cut into the fastener element E having a predetermined thickness. Then, the 1 st hammer 21 is further retracted, so that the coupling head portion E1 of the fastener element E is fitted into the molding recess 43a of the molding die 43, and the pair of leg portions E2 of the fastener element E are fitted into the recess portions 61a of the left and right pressing punches 61 of the pressing portion 60, respectively. Thus, the fastener element E is fitted into and held by the molding recess 43a of the molding die 43 and the recesses 61a of the left and right pressing punches 61. At this time, the fastener tape T is fed upward by the tape feeding section 110 by the thickness of the two fastener elements E.
Next, as shown in fig. 19 and 20, the 2 nd hammer 41 moves downward, the element pressing pad 44 presses the pair of leg portions E2 of the fastener element E downward, the forming punch 42 performs scoring on the coupling head E1 of the fastener element E, and the coupling convex portion E3 and the coupling concave portion E4 are formed on the coupling head E1 of the fastener element E. The engaging convex portion E3 is formed by the forming concave portion 43a of the forming die 43, and the engaging concave portion E4 is formed by the tip end portion of the forming punch 42. In addition, the 2 nd hammer 41 moves upward rapidly after the formation of the engagement head E1.
Next, as shown in fig. 21 and 22, the 1 st ram 21 is advanced, so that the fastener element E moves toward one side edge portion of the fastener tape T, the one side edge portion of the fastener tape T is inserted between the pair of leg portions E2, and the pair of leg portions E2 are respectively pressed toward the fastener tape T side by the left and right pressing punches 61 of the pressing portion 60 which are advanced inward in the width direction, so that the fastener element E is attached to the one side edge portion of the fastener tape T.
At this time, as shown in fig. 23, since the left and right chamfering punches 62 advance inward in the width direction together with the left and right pressing punches 61, the corner portion of the fastener element Eb attached to the fastener tape T one before the fastener element Ea currently attached to the fastener tape T is chamfered by the chamfering portion 62a of the chamfering punch 62. Thereafter, the fastener element E is continuously attached to one edge portion of the fastener tape T by repeating the above operation.
As described above, according to the fastener stringer manufacturing apparatus 10 of the present embodiment, the molding die 43 is formed integrally with the die main body 28 of the cutting die 22, so that the number of parts can be reduced, and thus the manufacturing cost can be reduced.
In the conventional fastener stringer manufacturing apparatus, since the spacers are manually aligned with the mold body in the vertical direction (height direction), the operation of the apparatus needs to be stopped for a long time when the mold body is replaced, and the operation efficiency of the apparatus is lowered. However, in the present invention, the positioning operation itself does not exist because the molding die 43 is formed integrally with the die body 28 and the die body 28 is positioned in the vertical direction by placing the die body 28 on the table portion 26a of the gasket fixing member 26. Therefore, it is not necessary to stop the operation of the apparatus for a long time in order to replace the parts, and the operation efficiency of the apparatus can be improved.
Further, according to the fastener stringer manufacturing apparatus 10 of the present embodiment, since the fitting recess 25a is formed along the vertical direction at the front end portion of the lower die base 25 and the cutting die 22 is fitted into the fitting recess 25a to perform the positioning of the cutting die 22 in the lateral direction, the gasket 27 and the die main body 28 do not need to be positioned in the lateral direction by manual work when the gasket 27 and the die main body 28 are attached. Therefore, it is not necessary to stop the operation of the apparatus for a long time in order to replace the parts, and the operation efficiency of the apparatus can be improved.
Further, according to the fastener stringer manufacturing apparatus 10 of the present embodiment, since the fitting concave portion 27b is formed along the left-right direction on the rear surface of the spacer 27 and the spacer 27 is positioned in the vertical direction by fitting the fitting concave portion 27b to the front end portion of the lower die holder 25, the spacer 27 does not need to be positioned in the vertical direction by manual work when the spacer 27 is attached. Therefore, it is not necessary to stop the operation of the apparatus for a long time in order to replace the parts, and the operation efficiency of the apparatus can be improved.
The present invention is not limited to the above-described embodiments, and can be modified as appropriate within a scope not departing from the gist of the present invention.
For example, the weight-reduced portion may be provided appropriately in the shim and the die body of the cutting die.
As a modification of the die main body 28, as shown in fig. 25, a communication hole 28c that communicates two intersecting cutting grooves 28a with two intersecting suction holes 28b may be removed. In this case, the chips and the like generated when the wire W is cut are not sucked by the cutting grooves 28a, but are sucked only by the suction holes 28 b.
