Description

THE SPACE FORMATION DEVICE, METHOD OF FORMATION OF SPACE, AND MANUFACTURING METHOD OF SLIDING BRACELET TECHNICAL FIELD The present invention relates to a space forming device, a space forming method, and a sliding fastener manufacturing method.

BACKGROUND OF THE INVENTION A space-forming device is known in which, in order to cut a plurality of slide fasteners of continuous fastener strips or in order to remove fastening components such as an upper stop, a lower stop and a slider, In desired positions of the elongate fastening bands, portions of elements firmly attached to a fastening tape are arranged to form a space where fasteners are not present in the fastening bands.

For example, Japanese Patent Laid-open No. 59-137140 (Patent Literature 1) discloses a device for automatically performing space formation and chain cutting fastening. The portions of the elements are cut with an element cutter arranged in a cutting element mechanism to form a space in a holding chain. Thereafter, the fastening chain is cut with a chain cutter arranged in a chain cutting mechanism at a predetermined position in the space, whereby the manufacture of a fastening chain is equipped with a fly (cloth). ).

Japanese Patent Laid-Open No. 8-322612 (Patent Literature 2) discloses a space device for more effectively removing fasteners without causing damage to a part of the core. In this device, the portions of the ends of the rows of coupling elements are cut with a cutting blade, while the clamping heads present in a section of the rows of clamping elements forming a space with a punch and a given, to separate the extremities. After cutting, the coupling heads and the remains of the remaining limbs in a fastening tape are pushed down and removed, while holding the coupling heads and the remains of the extremities with the punch and die, forming this way a space where the elements are not present in a fastener.

The space formation devices described above are provided with an alignment mechanism to restrict the displacement of a space. In the separation device of Patent Literature 1, for example, a The alignment strip is pushed downwards by a helical compression spring which is arranged in a blind hole provided in the lower part of a piston for upward and downward movement. This alignment strip moves downward as the piston lowers and fits between the elements to position the space. In the separation device of the Patent Literature 2, two positioning pins are arranged on the front and back of the cutting blade, and a space is made by controlling and coupling the two positioning pins with the elements.

The alignment strip described in Patent Literature 1 moves up and down together with the cutting element, while being constantly pushed by the spring. Accordingly, the alignment strip remains in a state of the application of an elastic force to the elements, even when the piston rises after the elements are cut with the cutting element by reduction of the piston. Accordingly, unnecessary force can be applied to the elements when the piston is raised, and therefore the misalignment of fastening bands can occur. Furthermore, in the separating device described in Patent Literature 1, the remains of clamping cutting elements can not be completely eliminated, and therefore, remain in the tape. The remains can thus be obstacles when manufacturing fastener materials in subsequent processes.

In the device described in Patent Literature 2, the remains of the cutting elements can be removed more safely by pushing the elements after cutting down the punch, as illustrated in, for example, Figure 5. the separating device described in Literature Patent 2, however, the final alignment has to be made while respectively controlling the two positioning pins placed on the front and rear of the blade and a tension bar of the chain or a chain suppression bar located separate from the positioning pins. Consequently, the device requires a greater number of components and is complex in the alignment operation and control mechanism.

It is intended that in the embodiments shown hereafter, cite the devices and methods that materialize the technical idea of the present invention as examples. Therefore, the technical idea of this invention does not want to concretize structures, designs and materials of constituent parts such as those described below.

Slide bra 10 Before describing a training device space 100 according to one embodiment of the present invention, an example of a slide fastener 10 capable of being manufactured using the space forming device 100 is illustrated in Figure 1. The slide fastener 10 includes a pair of fastening bands of 14 wherein a plurality of fastening elements 13 (hereinafter, "elements") are arranged in a row on each side of the tape of opposite edges 12 of fastening tapes 11; an upper stop 15 disposed at one end of each row of elements 13; a lower stop 16 disposed at the other end of the rows of elements 13 through both fastening tapes 11; and a sliding slide 17 slidably disposed along the rows of elements 13. Each element 13 is formed from metal or resin and includes a coupling head 131, a body portion 132 extending from the head coupling 131 towards the side of the fastening tape 11, and an end portion 133 extends farther from the body portion 132 towards the fastening tape side 11 and is fixed to the side edge of tape Such elongate fastening strips 14, as illustrated in Figure 2, are prepared when the sliding fastener 10 illustrated in Figure 1 is manufactured. The elongated fastening strips 14 are prepared with the opposite plurality of elements 13 coupled together in the tapes. 11. As shown in Figure 3, in the holding rails 14, the portions of the elements 13 are arranged by the space forming device 100 which will be described later in Figure 4 to form a space S where the elements 13 are not present. Then, the slide fastener 10 illustrated in Figure 1 can be manufactured by cutting the clamping stringers 14 and / or arranging the clamping components, such as the upper stops 15 and the lower stop 16, in these spaces S and joins sliding slide 17.

That is to say, the holding beams 14 are cut in the space S to manufacture the sliding fastener 10 equipped with the slide 17. Alternatively, the best stops 15 and the lower stop 16 are equipped and arranged in the space S without cutting the longitudinal beams clamping 14 and then the clamping stringers 14 are cut to make the slide clamp 10.

Note that in a case where the best stops 15 and the bottom stop 16 are not discarded, this slide fastener 10 is sewn to a garment or bag to be equipped with the clamping device, thus making it possible to prevent the slide 17 from falling out of the rows of coupling elements. It is also possible to arrange the upper stops 15 or the lower stop 16.

Space Formation Device 100 Figure 4 illustrates a schematic view of the space forming device 100 according to an embodiment of the present invention. The space-forming device 100 includes a base 1 in which the fastener element 14 to be transported is placed; a cutting part 2 up and down arranged movably on the base 1 to cut portions of the elements 13; an alignment mechanism 3 for positioning the holding stringers 14; an energizing mechanism 4 connected to the alignment mechanism 3; and a punch 6 and a die 7 (see Figure 5 for the die 7) to hold the remains of the cut elements 13 with the cutter part 2 and pushing out these debris down the base 1 to remove the debris of the elements 13 of the stringers of the fastener 14.

As illustrated in Figure 4, the pairs of guide rollers 8 and 9 for transporting the fastener element 14 in the base 1 are arranged on the front and the back of the fastening stringers 14, respectively, in a transport direction (direction of the arrow A) through the base 1. Note that in the description given below, the direction of travel in the transport direction A of the holding stringers 14 is represented as " front side (or the front side of the conveying direction) ", and the direction of travel opposite to the conveying direction of the holding rails 14 is represented as" rear part (or the rear part of the transport direction) " .

As illustrated in Figure 6, a pair of mutually opposite cutting edges 21 are disposed at the forward ends of the cutting part 2. The cutting edges 21 extend parallel to the longitudinal direction of the holding stringers 14, as it is illustrated in Figure 4. The cutting part 2 moves above the base 1 to cut the elements 13 of the holding beams 14. The cutting part 2 is driven by a press piston (not shown) arranged in an upper portion of the cutting part 2 and connected thereto, and can move up and down above the base 1.

A slot 22 inclined with respect to the upper surface of the base 1 is formed inside the cutting part 2. The bar alignment mechanism 3 is housed in this slot 22 to move up and towards down above the base 1 in relation to the rise and fall of the blade part 2. The alignment mechanism 3 can be moved along this groove 22. The alignment mechanism 3 is disposed obliquely to the upper surface of the base 1, so that the upper part of the alignment mechanism 3 is placed on the front side of the transport direction A and the lower part of the alignment mechanism 3 is placed on the rear side of the transport direction A. Alignment mechanism 3 includes, at one end thereof, a hook part 31, of which the front end is finely formed. As understood from Figures 4 and 5, the part of the hook 31 protrudes downwardly from the cutting edges 21 of the cutter part 2.

As illustrated in Figure 4, the energizing mechanism 4 for driving the alignment mechanism 3 is connected to one end of the alignment mechanism 3 on the opposite side of the hook part 31. The energizing mechanism 4 drives the mechanism of alignment 3 obliquely downwards from the front to the rear of the transport direction along the slot 22. With this energization obliquely downward, the single unit of the alignment mechanism 3 adjusts to the hook part 31 between adjacent elements 13. As the result of the cutting part 2 moves further down, the alignment mechanism 3 moves obliquely upwards relative to the cutting part 2 along the groove 22. This oblique upward movement causes the hook part 31 to fit between the elements to engage with the elements 13 on the side front of the transport direction and allows the positioning where the holding stringers 14 are attracted (pulled) to the transport direction side A (front side of the transport direction). That is to say, the holding stringers 14 are placed in a direction closer to the cutting part 2 from a position in which the holding stringers 14 are placed before being pulled by the alignment mechanism 3. Consequently, the elements 13 a cutting can be positioned below the cutting edges 21 of the cutting part 2. The side of the transport direction A refers to a direction towards the front side of the transport direction. That is, the positions of the elements 13 and the part of the hook 31 before transport are taken as reference and the side of the forward transport direction from the reference positions is defined as the side of the transport direction A. Details of positioning operation will be described later.

The energizing mechanism 4 is not limited to a specific mechanism, as long as the activation mechanism is a device capable of switching between the energization / de-energization of the alignment mechanism 3. In the present embodiment, an air cylinder, for example, is suitably used. By adopting a device, such as the air cylinder, capable of switching between energizing / deenergizing the alignment mechanism 3 as the energizing mechanism 4, it is possible to control the energization and de-energization of the alignment mechanism 3 according to the operation movement up and down of the cutting part 2. Accordingly, there is no need to apply unnecessary force to the fastening bands 14, as compared to a case where the alignment mechanism 3 is constantly pushed by a spring as practiced conventionally, thereby avoiding misalignment of the stringers of the fastener 14.

An energizing control mechanism 5 for controlling the triggering mechanism 4 is connected to the energizing mechanism 4. The energizing control mechanism 5 controls the energizing mechanism 4 based on the operation of the cutting part 2 and the mechanism of alignment 3. For example, the energizing control mechanism 5 places the activation mechanism 4 in an energizing state when the cutter of part 2 moves down over the base 1. If the cutter of part 2 moves above base 1, the mechanism of energization control 5 places the activation mechanism of 4 in a de-energized state.

In a case in which an air cylinder, for example, is adopted as the energizing mechanism 4, the energizing control mechanism 5 supplies air to the air cylinder at the outlet with a signal to activate the alignment mechanism, when the part of the cutter 2 moves downwardly above the base 1. The energizing control mechanism 5 stops the supply of air to the air cylinder at the outlet a signal to de-energize the alignment mechanism 3, when the cutter part 2 it moves above the base 1. There is no particular limit on specific modalities of the energizing control mechanism 5. For example, the energizing control mechanism 5 can be constructed in an arithmetic control circuit (not illustrated) to control the operation of the respective components of the device space 100, such as the formation of the cutting part 2, the punch 6 and the matrix 7.

As illustrated in Figure 5, the punch 6 is arranged in a central region inserted by the pair of the cutting part 2. The matrix 7 is arranged in a space formed in the center of the base 1, so that it faces towards the punch 6. The punch 6 and the matrix 7 can move up and down above the base 1. When moving the remains of the elements 13 downwards from the base 1, while the remains of the grip with the punch 6 and the matrix 7 and keep the remains between them, it is possible to safely eliminate the remains of cutting elements 13 of the stringers 14. Therefore, a space S can be formed more securely on the support stringers 14.

Space formation method A method of forming a space according to an embodiment of the present invention will be described using Figures 4 and 7 to 13. First, the fastening stringers 14 illustrated in Figure 2 are transmitted to the base 1 by the rollers. 8 and 9 illustrated in Fig. 4. When the support of stringers 14 are placed in a correct position in the base 1 by a position detector (not shown), a piston of the press (not shown) connected to the part of cutting 2 decreases, and the cutting part 2 and the alignment mechanism 3 connected to the press piston move downwards on the holding beams 14. Since the part of the hook 31 located at the front end of the alignment mechanism 3 is placed below the cutting edges of the cutting part 2, as illustrated in Figure 7, the part of the hook 31 comes into contact with the previous elements 13 of the cutting part 2.

After coming into contact with the elements 13, the part of the hook 31 fits between an element 13a and an element 13b adjacent to each other, as illustrated in Figure 8, as a result of the part of the cut 2 moves further downward . As the cutting part 2 moves down further, a bar-like portion of the alignment mechanism 3 slides obliquely up (in the direction of an arrow B in Figure 9) along the groove 22, under the condition of the part of the hook 31 is in a position represented by a dotted line in Figure 9 in a positional relationship with the cutter of part 2 shown by the dotted lines in Figure 9 being pushed by the mechanism of energization 4 to adapt between the element 13a and the element 13b and pulling the element 13a and the element 13b towards the side of the transport direction A. Therefore, on the part of the hook 31 of the alignment mechanism 3, the the positioning in which the clamping stringers 14 are attracted towards (taken out) the side of the transport direction A. As a result, the cutting part 2 is adjusted to a correct position in the clamping stringers 14, as is shown by a solid line in Figure 9, when the cutting edges 21 of the cutting part 2 come into contact with an element 13c.

According to the space-forming device 100 according to the embodiment of the present invention, the holding beams 14 are placed in a correct position as a result of the alignment mechanism 3 moving within a limited space of the groove 22. Accordingly, it is possible to prevent the element 13a from being cut and being adjacent to the element 13c to be cut which is cut by the cutting part 2 and removed due to the misalignment.

After the cutting edges 21 of the cutting part 2 come into contact with the elements 13, a predetermined pressure is applied downwards from the cutting edges 21 as illustrated in Figure 10 to cut portions 134 of the elements 13. (corresponding to the limb portions 133 in Figure 1) and separate the portions. After cutting, the energizing control mechanism 5 cancels the state in which the alignment mechanism 3 is driven by the energizing mechanism 4. Subsequently, the cutting part 2 and the alignment mechanism 3 are moved up again above the base 1, as illustrated in Figures 11 and 12. Observe whether the alignment mechanism 3 is maintained driven as is conventionally practiced, the part of the hook 31 of the alignment mechanism 3 moves the elements 13a and 13b to the rear part of the transport direction of the holding beams 14 due to the elevation of the cutting part 2. Since the alignment mechanism 3 according to the embodiment of the present invention is in a state to be released from downward energization by the energizing mechanism 4, however, the alignment mechanism 3 moves upward directly from a finally fixed position (position shown by a dotted line) together with the elevation of the cutting part 2, as illustrated in Figure 11.

As illustrated in Figure 13, the punch 6 moves down on the elements 13 of the cutting edge pair 21 of the cutting part 2 to hold the remains of the elements 13 (corresponding to the coupling of the heads 131 and the body portions 132 are illustrated in Figure 1) with the punch 6 and the die 7 and the debris is pushed outwardly from the base 1. Accordingly, the elements 13 are safely removed from the stringers 14, and fastening stringers 14 are fabricated including such space S, as illustrated in Figure 3.

According to the space forming device 100 according to the embodiment of the present invention and the method of space formation using the device space, the energization of the alignment mechanism 3 formed by the energizing mechanism 4 is canceled by the energizing mechanism 4 and the energizing control mechanism 5 for controlling the energizing mechanism 4, when the alignment mechanism 3 moves upwards. Since the downward energization of the alignment mechanism 3 is canceled accordingly, the alignment mechanism 3 is adjusted between the elements 13 not pulling the elements 13 towards the rear side of the transport direction when moving along with the part As a result, it can be avoided that the fastener stringers 14 become misaligned. As a result of the prevention of the clamping stringers 14 becoming misaligned, the remains of the elements 13 can be correctly clamped with the punch 6 and the die 7 also when the remains of the elements 13 after cutting are subsequently removed from the stringers of clamping 14 using the punch 6 and the matrix 7. Accordingly, it is possible to provide the space of the device 100 capable of safely removing the broken elements 13. In addition to training, since the space forming device 100 in accordance with the embodiment of the present invention can pull (align) the fastening bands 14 to a correct position by means of the unique alignment mechanism 3, it is possible to reduce the number of components used for positioning and provide a space forming device having a simple configuration.

Other modalities Meanwhile, the embodiments of the present invention have been described, the descriptions and drawings constituting part of this description should not be construed as limiting the present invention. The present invention naturally includes the modalities not explicitly specified in the present document and can be modified and embodied in an implementation stage without departing from the object of the invention.

For example, in the above description, an example has been cited in which the air cylinder is adopted as the energizing mechanism 4. However, the energizing mechanism 4 is not limited to the air cylinder only. For example, it is also possible to use an energizing mechanism 40 using an elastic member 41, such as a spring, as illustrated in Figure 14.

The activation mechanism 40 includes the elastic member 41 for pushing the alignment mechanism 3, and a shift mechanism 42 and a shift bar 43, such as an air cylinder, capable of switching between downward energization of the alignment mechanism 3 along the slot 22 and the de-energization of the alignment mechanism 3 by stopping the movement of the elastic member 41. The elastic member 41 is connected to one end of the alignment mechanism 3. As illustrated in Figure 15, a depression 33 engageable with the forward end of the shift bar 43 is provided in the alignment mechanism 3. The shift bar 43 advances and retracts in a direction in which the shift bar 43 contacts or moves away from the alignment mechanism 3, and stops movement of the elastic member 41 by engaging with the depression 33.

In this case, as in the embodiment described above, the part of the hook 31 of the alignment mechanism 3, after coming into contact with the elements 13, fits between the element 13a and the element 13b adjacent to each other as a result of the cutter from part 2 moves even more. As the cutter part 2 moves further, the bar portion of the alignment mechanism 3 slides obliquely upwards along the slot 22 provided in the cutting part 2, under the condition of the part of the The hook 31 is pushed by the elastic element 41 to fit between the element 13a and the element 13b and pull the element 13a and the element 13b towards a side A of the transport direction. Therefore, on the part of the hook 31 of the alignment mechanism 3, positioning is carried out in which the stringers of 14 are attracted to (take off) the side of the transport direction A. Then, after the cutting edges 21 of the cutting part 2 comes into contact with the elements 13 to cut the portions 134 (corresponding to the end portions 133 illustrated in Figure 1) of the elements 13 and causing the portions to separate, the shift mechanism 42 is actuated to engage the forward end of the shift bar 43 with the depression 33 of the alignment mechanism 3 ( see Figure 15). Therefore, the shift mechanism 42 cancels the state in which the alignment mechanism 3 is pushed by the elastic member 41.

Subsequently, the cutting part 2 and the alignment mechanism 3 moved again above the base 1. Since the shift mechanism 42 places the alignment mechanism 3 in a state of being released from energization downwardly by the elastic element 41 at this time, the alignment mechanism 3 moves upward directly from a finally fixed position (position shown by a dotted line), in relation to the elevation of the cutting part 2.
