Description

Technical Field

[0001] This invention relates to a zipper pull separation mechanism and a zipper pull separation method, and more particularly to an apparatus and method for separating the zipper pull body of a metal zipper pull from a locking pin. Background Technology

[0002] Japanese Patent Application Publication No. 2022-175567 (Patent Document 1) discloses a method for recycling metal sliders and the like. In the method of Patent Document 1, a crusher is used to separate the slider into a slider body, a locking pin, and a slider tab, which are its constituent components. However, in the method of Patent Document 1, during the crushing of the slider, for example, a portion of the stainless steel locking pin may adhere to the copper alloy slider body, resulting in stainless steel becoming mixed with the copper alloy. In this case, it creates a problem that hinders the reuse and recycling of the separated components by dissolving them.

[0003] Chinese Patent No. 105962553 (Patent Document 2) discloses the following technique: The slider is fixed, and a punched pin is used to press the front part of the locking pin from below (lower wing plate side) to above (upper wing plate side) the slider body, thereby separating the locking pin from the slider body. In this technique, the slider body, locking pin, and slider are pulled apart at once. However, because the top of the locking pin has a retaining engagement portion relative to the body, high pressure needs to be applied to the punched pin in the technique of Patent Document 2. Furthermore, the following situations may occur: the body deforms but the locking pin does not fall off, and stainless steel becomes mixed with copper alloy.

[0007] Patent Document 2: Specification of Chinese Patent No. 105962553 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] In view of the aforementioned problems, the object of the present invention is to provide a slider separation mechanism and a slider separation method in which the metal materials of the slider body and the locking pin do not adhere and mix, and the slider can be separated without high pressure.

[0010] [Methods used to solve problems]

[0011] To address the aforementioned issues, according to one aspect of the present invention, a zipper pull separation mechanism (100) is provided for separating the zipper pull body (10), locking pin (30), and pull tab (40) from a zipper pull (1), wherein the zipper pull (1) comprises:

[0012] The zipper body (10) has an upper wing plate (11), a lower wing plate (12) and a guide post (13) connecting the upper wing plate (11) and the lower wing plate (12).

[0013] The locking pin (30), which is a resilient plate-shaped member, is mounted on the upper wing plate (11). A locking portion (34) at one end of the locking pin (30) engages with a locking portion (13a) in the front portion of the slider body (10); and

[0014] The pull tab (40) is disposed between the upper wing plate (11) and the locking pin (30), wherein,

[0015] The zipper pull separation mechanism (100) includes a locking release part (120, 120B) which is used to displace the locking part (34) of the locking pin (30) that engages with the locking part (13a) of the zipper pull body (10) in front of the guide post (13) to release the engagement.

[0016] In this invention, firstly, at the engagement / disengagement part of the pull-head separation mechanism, the engagement part of the locking pin is moved forward (see reference). Figure 2 , Figure 3 The locking pin moves away from the locking part of the zipper head body, thereby releasing the engagement between the locking part and the locking part. Even if the engagement between the locking part and the locking part is released, the locking pin remains engaged with the zipper head body by means of the part other than the locking part.

[0017] In one embodiment of the present invention, the engagement release portion (120, 120B) includes a separation portion (130) for contacting the engagement portion (34) to separate the locking pin (30) from the slider body (10). In this manner, after the engagement of the locking pin engagement portion with the slider body's locking portion is released, the locking pin is completely separated from the slider body at the separation portion of the engagement release portion. Thus, firstly, the engagement of the locking pin engagement portion with the slider body's locking portion is released, and then the locking pin is separated from the slider body. As a result, the metal materials of the slider body and the locking pin can be separated without adhesion and mixing. Furthermore, the slider can be separated without high pressure.

[0018] In one embodiment of the invention, the locking pin (30) includes a curved portion (33c) that bends from the upper wing plate (11) side of the slider body (10) toward the guide post (13) side, and the engagement release portion (120) further includes an abutment portion (125) that includes a protruding member (121) that abuts against the curved portion (33c). In this manner, by abutting the protruding member of the abutment portion of the engagement release portion against the curved portion of the locking pin, the engagement portion of the locking pin can be displaced forward toward the guide post of the slider body, thereby releasing the engagement between the engagement portion of the locking pin and the locking portion of the slider body. If the protruding member abuts against the curved portion, the shape of the curved portion undergoes plastic deformation and loses the elasticity (locking property) of the locking pin, thereby lifting the engagement portion from the locking portion and releasing the engagement.

[0019] In one embodiment of the invention, the zipper (1) has a gap (G) extending in the left-right direction between the zipper body (10) and the locking pin (30). The engagement release portion (120) further includes an abutment portion (125B), which includes an insertion member (123) that is inserted into the gap (G) to widen it. In this manner, at the engagement release portion, by inserting the insertion member into the gap to widen it, the engagement portion of the locking pin can be displaced forward of the guide post of the zipper body, thereby releasing the engagement between the engagement portion and the locking portion of the zipper body. If the insertion member widens the gap, the shape of the bent portion undergoes plastic deformation and loses the elasticity (locking property) of the locking pin, thereby lifting the engagement portion from the locking portion and releasing the engagement.

[0020] In one embodiment of the invention, the separating part (130) includes a push rod (131) that abuts against the engaging part (34) of the locking pin (30). In this manner, the pull head separates into the pull head body and the locking pin by the push rod of the separating part abutting against the engaging part of the locking pin, and the pull tab also separates accordingly.

[0021] In one embodiment of the present invention, the engagement release unit (120, 120B) further includes a positioning unit (126) for holding the slider (1), the positioning unit (126) including a main positioning stop (127) capable of switching between a holding state and a release state. The slider is positioned by the positioning unit. The main positioning stop of the positioning unit stops the slider supplied from the slider supply unit at a predetermined position and holds it. The main positioning stop can switch between a holding state (holdable position) where the slider can be held and a release state (non-holdable position) where the slider cannot be held. The slider held by the main positioning stop in the holding state is engaged, disengaged, and separated based on the engagement release unit.

[0022] In one embodiment of the invention, the slider separation mechanism (100) further includes a recovery section (140), which has a vibrating screen (143) with a plurality of through holes (143a), the diameter of which is such that the locking pin (30) can pass through but the slider tab (40) and the slider body (10) cannot. In this manner, the slider body, locking pin, and slider tab, which are further separated after being released from engagement by the engagement release section, are recovered to the recovery section and pass through the vibrating screen. At the vibrating screen, only the locking pin passes through the through holes, while the slider tab and slider body remain outside the through holes.

[0023] According to another aspect of the present invention, a method for separating a zipper pull is provided, which is used to separate the zipper pull body (10), the locking pin (30) and the pull tab (40) of a zipper pull (1), the zipper pull (1) comprising:

[0024] The zipper body (10) has an upper wing plate (11), a lower wing plate (12) and a guide post (13) connecting the upper wing plate (11) and the lower wing plate (12).

[0025] The locking pin (30), which is a resilient plate-shaped member, is mounted on the upper wing plate (11). A locking portion (34) at one end of the locking pin (30) engages with a locking portion (13a) in the front portion of the slider body (10); and

[0026] The pull tab (40) is disposed between the upper wing plate (11) and the locking pin (30), wherein,

[0027] The locking pin (30) includes a curved portion (33c) that bends from the upper wing plate (11) side of the zipper body (10) toward the guide post (13) side.

[0028] The method for separating the pull head includes the following steps:

[0029] In the engagement release process, the protruding member (121) in the abutment portion (125) abuts against the curved portion (33c), causing the engaging portion (34) of the locking pin (30) that engages with the locking portion (13a) of the slider body (10) to displace forward of the guide post (13) and release the engagement; and

[0030] In the separation process, after the engagement release process, the push rod (131) abuts against the engagement portion (34) of the locking pin (30).

[0031] According to another aspect of the present invention, a method for separating a zipper pull is provided for separating a zipper pull body (10), a locking pin (30), and a pull tab (40) in a zipper pull (1). The zipper pull (1) comprises: a zipper pull body (10) having an upper wing plate (11), a lower wing plate (12), and a guide post (13) connecting the upper wing plate (11) and the lower wing plate (12); a locking pin (30) being an elastic plate-shaped member mounted on the upper wing plate (11), wherein an engaging portion (34) at one end of the locking pin (30) engages with a locking portion (13a) in the front portion of the zipper pull body (10); and a pull tab (40) disposed on the upper wing plate (11) and the... Between the locking pins (30), wherein the pull head (1) has a gap (G) extending in the left and right direction between the pull head body (10) and the locking pins (30), the pull head separation method includes the following steps: a locking release step, in which the insertion member (123) in the abutment part (125B) is inserted into the gap (G), so that the locking part (34) of the locking pin (30) that is engaged with the locking part (13a) of the pull head body (10) is displaced forward of the guide post (13) to release the engagement; and a separation step, after the locking release step, in which the push rod (131) abuts against the locking part (34) of the locking pin (30).

[0032] In one embodiment of the present invention, the pull head separation method includes a first falling step, in which, after the separation step, the abutment part (125, 125B) is reset to its initial position, and the push rod (131) is moved further forward, thereby causing the locking pin (30) and the pull tab (40) to fall.

[0033] In one embodiment of the present invention, the pull head separation method includes a second dropping step, in which the main body (10) is dropped by releasing the main body positioning stop (127) after the first dropping step.

[0034] [Invention Effects]

[0035] In this invention, firstly, the locking pin is released from its engagement with the locking part of the slider body. Then, the locking pin, slider body, and slider are separated. As a result, the metal materials of the slider body and the locking pin do not adhere and mix. In addition, the slider can be separated without high pressure. Attached Figure Description

[0057] (First Embodiment)

[0058] First, an example of a pull head (hereinafter also referred to as "SL"), which is the object to be separated and recycled in this invention, will be described based on the accompanying drawings. Figure 1 This is a 3D view of SL1. Figure 2 This is a top view of SL1. Figure 3 yes Figure 2 A sectional view along line AA. Figure 4 From Figure 2 Arrow B is used to observe the main view of SL1. Figure 5 This is an exploded perspective view of SL1. In the following, in this specification, the left-right, front-back, and up-down directions of SL1 will be... Figure 2 and Figure 4 The directions described are: left-right, front-back, and up-down, which are orthogonal to each other. SL1 is, for example, recycled from old clothes, etc., and separated by the pull-out separation mechanism 100 of the present invention (see reference). Figure 6 , Figure 7 Separate and recycle (etc.).

[0059] The slider (SL) 1 is, for example, made of metal and consists of three parts: the slider body (hereinafter also referred to as "body") 10, the locking pin 30, and the pull tab 40. As an example, the body 10 and the pull tab 40 are made of copper alloy, and the locking pin 30 is made of stainless steel, but this is not a limitation. If the body and the locking pin are made of different metals, a portion of the pull tab may contain non-metallic material or may be made of resin. Furthermore, the same SL is disclosed in Japanese Patent Application Publication No. 2002-10808, etc.

[0060] The main body 10 includes an upper wing plate 11, a lower wing plate 12, and a guide post 13 connecting the upper wing plate 11 and the lower wing plate 12. The upper wing plate 11 has a downwardly projecting upper flange 11a, and the lower wing plate 12 has an upwardly projecting lower flange 12a. A Y-shaped chain tooth guide passage 14 is defined between the upper wing plate 11 and the lower wing plate 12, and between the upper flange 11a and the lower flange 12a. The chain tooth guide passage 14 opens at the left and right shoulder openings 15 of the guide post 13 at the front of the main body 10, and at the rear opening 16. A groove 13b extending vertically is provided at the left and right center portions of the front surface of the guide post 13 at the front portion of the main body 10, i.e., the front surface of the guide post 13. On the front surface of the guide post 13 (the front surface of the groove 13b), left and right locking portions 13a protruding forward are provided at positions offset from the left and right center points in the left and right directions. A front protrusion 17 and a rear protrusion 18 are provided on the upper surface of the upper wing plate 11. Furthermore, the upper wing plate 11 has a through hole 19 adjacent to the rear of the front protrusion 17 and extending vertically, and a locking hole 20 adjacent to the rear of the rear protrusion 18 and extending vertically. In this embodiment, as part of the front portion of the main body 10, a groove is provided on the front surface of the guide post 13, and a locking portion 13a is provided in the groove, but this is not limited to this. For example, it may be configured such that the guide post 13 has a through hole extending vertically, and a locking portion is provided inside the hole of the through hole.

[0061] The locking pin 30 is a flexible plate-like member, elongated in both length and width directions. The locking pin 30 includes a base 31, a downwardly curved piece 33 extending forward and downward from one end (front end) of the base 31 along its length, and a locking claw 32 extending downward from the other end (rear end) of the base 31 along its length. An engaging portion 34 is provided at one end (front end) of the downward piece 33. The base 31 includes a tongue 35 cut in a Japanese ko shape and bent downward, the tongue 35 having an opening 35a extending through in the vertical direction (thickness direction). The locking claw 32 also has an opening 32a extending through in the vertical direction (thickness direction). In SL1, the locking pin 30 is mounted on the upper wing plate 11 of the main body 10, and the engaging portion 34 at one end of the locking pin 30 is received in the groove 13b of the guide post 13 of the main body 10 and engages with the main body 10. (See reference...) Figure 3The drooping piece 33 of the locking pin 30 includes an upper portion 33a mounted on the upper wing plate 11, a front portion 33b (including an engaging portion 34) received in the groove 13b of the guide post 13, and a curved portion 33c between the upper portion 33a and the front portion 33b. That is, the drooping piece 33 is connected in the order of the upper portion 33a, the curved portion 33c, and the front portion 33b. The curved portion 33c does not contact the upper wing plate 11 or the guide post 13, and can be described as a portion separate from the main body 10. The portion between the upper portion 33a, which serves as the first fulcrum, and the front portion 33b, which serves as the second fulcrum, is the curved portion 33c. The pull tab 40 is a plate-shaped member including a pivot 41. The pull tab 40 is disposed between the upper wing plate 11 and the locking pin 30. More specifically, the pivot 41 is mounted on the upper wing plate 11 of the main body 10 and is covered and engaged by the locking pin 30.

[0062] With the main body 10, locking pin 30, and pull tab 40 engaged, the pivot 41 of the pull tab 40 is placed between the front protrusion 17 and the rear protrusion 18 of the upper wing plate 11 in the main body 10. Next, the base 31 of the locking pin 30 is placed on the pivot 41, the locking claw 32 is inserted into the locking hole 20 of the upper wing plate 11, and the tongue 35 is inserted into the through hole 19 of the upper wing plate 11. At this time, the front protrusion 17 is inserted into the opening 35a of the locking pin 30, and the rear protrusion 18 is inserted into the opening 32a of the locking pin 30. Furthermore, the engaging portion 34 of the drooping piece 33 is received in the groove 13b of the guide post 13 and engaged with the locking portion 13a. (See reference...) Figure 4 and Figure 5 The drooping piece 33 is approximately T-shaped, with its width gradually narrowing from the upper portion 33a towards the front portion 33b, and having left and right protrusions at the engaging portion 34 that protrude to the left and right in a manner approximately the same width as the end of the upper portion 33a. At this time, the front portion 33b of the drooping piece 33, excluding the engaging portion 34, is positioned between the left and right locking portions 13a, and the left and right protrusions of the engaging portion 34 of the drooping piece 33 contact the left and right locking portions 13a respectively. By pressing the front protrusion 17 in this state, the main body 10, the locking pin 30, and the pull tab 40 engage, and the engaging portion 34 locks onto the lower surface of each locking portion 13a. The recycle SL1 is the state in which the main body 10, the locking pin 30, and the pull tab 40 are engaged.

[0063] In the first embodiment of the pull-out mechanism 100 of the present invention, described later, the protruding member 121 of the engagement release portion 120 (see reference) is released by... Figure 11 (etc.) Strike the curved part 33c of the drooping piece 33, thereby displacing the engaging part 34 of the locking pin 30, which engages with the locking part 13a of the pull head body 10, forward of the guide post 13, and releasing the engagement between the engaging part 34 and the locking part 13a of the guide post 13.

[0064] Reference Figure 3 A gap G extending in the left-right direction exists between the main body 10 and the drooping piece 33 of the locking pin 30. More specifically, the gap G mainly exists between the curved portion 33c of the main body 10 and the drooping piece 33. In the second embodiment of the pull-out mechanism 100 of the present invention, described later, by inserting the engagement release portion 120B into the member 123 (see...) Figure 16 The gap g is widened by inserting the main body 10 into the gap g between the front portion 33b of the drooping piece 33, thereby displacing the engaging portion 34 forward of the guide post 13, and releasing the engagement between the engaging portion 34 and the locking portion 13a of the guide post 13. The gap g is a part of the gap G.

[0065] Next, several embodiments of the present invention will be described. Figure 6 This is a schematic structural diagram illustrating the pull head (SL) separation mechanism 100 and the SL separation method of the present invention. The SL separation mechanism 100 includes a pull head (SL) supply section 110, engagement / disengagement sections 120 and 120B, a separation section 130, and a recovery section 140 (regarding the engagement / disengagement section 120B, see...). Figure 17 In the first and second embodiments of the present invention, the separating part 130 is part of the engaging and disengaging parts 120 and 120B, but it is not limited thereto, and the separating part 130 may also be independent of the engaging and disengaging parts 120 and 120B. Figure 7 This is a diagram showing the pull head (SL) separation mechanism 100 viewed from the left. Figure 8 This is a diagram showing the pull head (SL) separation mechanism 100 viewed from the front. Figure 9 This is a view of the locking and unlocking section 120 of the first embodiment from the left. Figure 10 This is a diagram showing the disengagement mechanism 120 from the front. Figure 11 yes Figure 9 Enlarged views of the main parts. Figures 12(a), (b), (c), (d), and (e) show the operation flow of the separation unit 130, respectively. Figure 13 This is a view of the recycling section 140 from above. The SL supply section 110 includes a feeder (or hopper) 111 and a chute 112. Multiple SL1s separated from clothing, etc., are housed in the feeder 111. Figures 1-4 As shown, SL1 housed in the feeder 111 is in a state where the main body 10, locking pin 30 and pull tab 40 are engaged.

[0066] The SL supply unit 110 supplies SL1 units one by one from the feeder 111 to the engagement release unit 120 via the slide 112. The engagement release unit 120 disengages the engagement portion 34 of the locking pin 30, which engages with the locking portion 13a of the pull head body 10, by moving it forward toward the guide post 13 (engagement release process), details of which will be described later. At this time, the base 31 of the locking pin 30 and the like are still engaged with the body 10, and the pull tab 40 is also engaged with the body 10. Next, the separation unit 130 operates. The separation unit 130 separates the locking pin 30, the body 10, and the pull tab 40 after the engagement of the engagement portion 34 has been released (separation process). The locking pin 30 and the pull tab 40 are completely pulled away from the body 10 by the separation unit 130. Thus, the SL1 is separated into the body 10, the locking pin 30, and the pull tab 40 as constituent components. The main body 10, locking pin 30, and pull tab 40 are discharged and distributed from the separation section 130 to the recycling section 140, where they are housed and recycled according to their components.

[0067] The engagement release section (engagement release process) 120 will be described in further detail below. In the first embodiment of the SL separation mechanism 100, the engagement release section 120 includes a protruding member 121. Figure 9 , Figure 11 , Figure 15 In the drawing, the upper wing 11 is shown on the right, the lower wing 12 on the left, and the guide post 13 is shown at the top. Additionally, Figure 9 , Figure 11 , Figure 15 The top of the paper corresponds to the front of SL1, and the bottom corresponds to the back of SL1.

[0068] The engagement / disengagement unit 120 includes a positioning unit 126, an abutment unit 125, and a disengagement unit 130. The positioning unit 126 includes a main body positioning stop 127, which holds the SL1 supplied from the SL supply unit 110. Specifically, the SL1 is placed on the main body positioning stop 127. The main body positioning stop 127 can hold the SL1 when it is in a left-right inward state (holding state), and cannot hold the SL1 when it is in a left-right outward state (disengagement state), causing the SL1 to fall. The main body positioning stop 127 can switch between the holding state and the disengagement state. The main body positioning stop 127 is driven, for example, by an actuator such as a cylinder, to move between the holding state and the disengagement state.

[0069] The contact portion 125 includes a rotating portion 129 having a protruding member 121 and a drive portion 122 for driving the rotating portion 129. The protruding member 121 is a rod-shaped member protruding from the rotating portion 129. The rotating portion 129 rotates about a shaft 129a via the drive portion 122. Through this rotation, the protruding member 121 can move back and forth approximately along its axial direction (front-back direction). The drive portion 122 can be, for example, an actuator such as a cylinder that moves the rod 122a in and out, but is not limited to this. The separation portion 130 has a push rod 131 that can move in the left-right direction. The push rod 131 is driven, for example, by an actuator such as a cylinder.

[0070] Next, the operation flow of the locking release unit 120 will be described in detail. Referring to FIG12(a), SL1, supplied from SL supply unit 110 to locking release unit 120, stops at a predetermined position, and the main body 10 is held and fixed in the holding state by the main body positioning stop 127. At this moment, the protruding member 121 of the abutment portion 125 is in the initial position, separated from the bent portion 33c of the locking pin 30. The push rod 131 of the separation portion 130 is also in the initial position, separated from the front portion 33b of the locking pin 30. In addition, at this moment, the locking portion 34 of the locking pin 30 is engaged with the locking portion 13a of the main body 10 (see reference). Figure 15 (dashed line).

[0071] Next, refer to Figure 12(b) and Figure 11 The drive unit 122 is activated, causing the rotating unit 129 to rotate counterclockwise by a predetermined angle and stop. This causes the protruding member 121 to move rearward from its initial position in the forward-backward direction and abut against the curved portion 33c of the locking pin 30. The protruding member 121 stops in the state of abutting against the curved portion 33c. Figure 15 This is a side view schematically showing the state in which the protruding member 121 abuts against the curved portion 33c of the locking pin 30. Figure 15 The structure of the abutment portion 125, excluding the protruding member 121, is omitted. It can be said that the protruding member 121 strikes or hits the bent portion 33c. As a result, the bent portion 33c deforms towards the gap G side, and the engaging portion 34 of the locking pin 30, which engages with the locking portion 13a of the main body 10, moves forward from the locking portion 13a of the guide post 13 (in...). Figure 15 (From top to bottom) Displacement occurs, and the engagement between the engaging portion 34 and the locking portion 13a is released. More specifically, by striking the bent portion 33c with the protruding member 121, the shape of the bent portion 33c undergoes plastic deformation, thereby losing the elasticity (locking property) of the locking pin 30, and the engaging portion 34 is lifted from the locking portion 13a. The front portion 33b of the locking pin 30 is displaced approximately 30 degrees forward of SL1, for example, with the contact point between the protruding member 121 and the bent portion 33c as the center (engagement release process).

[0072] Next, referring to Figure 12(c), with the protruding member 121 abutting against the bent portion 33c, the push rod 131 is activated. The push rod 131 is moved forward in the forward-backward direction from its initial position and stops abutting against the plastically deformed engaging portion 34 of the locking pin 30. As a result, the locking pin 30 separates from the main body 10, and the pull tab 40 also substantially separates (separation process). At this moment, the main body 10 remains held in place by the main body positioning stop 127.

[0073] Next, referring to Figure 12(d), the rotating part 129 of the abutment part 125 is rotated clockwise to return the protruding member 121 to its initial position. Simultaneously, the push rod 131 is moved further forward. As a result, the locking pin 30, separated from the main body 10, is pushed forward, causing the locking pin 30 and the pull tab 40 to fall through the falling passage 149 to the lower retraction part 140 (first falling process). In Figure 12(d), the locking pin 30 and the pull tab 40 during their fall are indicated by dashed lines.

[0074] Next, referring to FIG12(e), the main body positioning stop 127 is released. As a result, the main body 10 is lowered to the retraction section 140 (second lowering process).

[0075] The recovery unit 140 is equipped with multiple through holes 143a (see reference). Figure 13 The vibrating screen 143 vibrates simultaneously in the vertical, horizontal, and front-back directions via the drive unit 144. The diameter of the through hole 143a is such that the locking pin 30 can pass through, but the pull tab 40 and the main body 10 cannot. In the recycling unit 140, the locking pin 30 is collected in the locking pin recycling box 141 located directly below the vibrating screen 143, and the pull tab 40 and the main body 10 are distributed via the slide 145 to the main body / pull tab recycling box 142 located further back than the locking pin recycling box 141. The vibrating screen 143 of the recycling unit 140 vibrates continuously. Furthermore, since the main body 10 is made of the same material as the pull tab 40, it is distributed to the same recycling box, but if the main body 10 and the pull tab 40 are made of different materials, separate recycling boxes can be prepared. With this arrangement, the metal materials of the pull head body and the locking pin will not mix, and the pull head can be separated without high pressure.

[0076] (A variation of the first embodiment)

[0077] Figure 14This figure shows a modified example of the abutment portion 125 in the first embodiment. The difference between this modified example and the aforementioned engagement release portion 120 is that the rotating portion 129B of the abutment portion 125 is shaped into a simple letter L. Otherwise, the structure is the same as the engagement release portion 120, and therefore the same reference numerals are used. The shape of the engagement release portion can be arbitrarily changed without affecting the device structure.

[0078] (Second Implementation)

[0079] Figure 16 This is a side view that roughly shows the state in which the insertion member 123 is inserted into the gap g of SL1. The gap g is a part of the gap G. Figure 17 This is a schematic side view showing the insertion member 123 and its driving part 124. In the second embodiment of the SL separation mechanism 100, the engagement release part 120B includes a positioning part 126, an abutment part 125B, and a separation part 130. The structures of the positioning part 126 and the separation part 130 are the same as in the first embodiment. The abutment part 125B includes the insertion member 123 and the driving part 124 that drives the insertion member 123. The insertion member 123 is a rod-shaped member with a top end 123b whose outer diameter gradually decreases towards the top end 123a. The outer diameter of the top end 123a is slightly smaller than the initial gap g, and the outer diameter of the rear end of the top end 123b is larger than the gap g. The insertion member 123 can be moved axially by the driving part 124, thereby being inserted into the gap g of the SL10 from the initial position in the left-right direction. Therefore, it can be seen that the approach direction of the insertion member 123 in the second embodiment and the protruding member 121 in the first embodiment abuts against the SL10 are different. The drive unit 124 may be composed of an actuator such as a cylinder, but is not limited thereto.

[0080] SL1, supplied from SL supply section 110 to engagement release section 120B, stops at a predetermined position, and the main body 10 is held and fixed by the main body positioning stop 127 in a holding state. At this moment, the insertion member 123 is in its initial position, separated from the bent portion 33c of the locking pin 30. The push rod 131 is also in its initial position, separated from the front portion 33b of the locking pin 30. In addition, at this moment, the engagement portion 34 of the locking pin 30 is engaged with the locking portion 13a of the main body 10 (see reference). Figure 16 (dashed line).

[0081] Next, the drive unit 124 is activated, inserting the insertion member 123 of the abutment portion 125B into the gap g. The insertion member 123 moves from its initial position in the left-right direction and enters the gap g from the top end 123a. Since the outer diameter of the rear end of the top end portion 123b of the insertion member 123 is larger than the outer diameter of the gap g, the gap g expands due to the stress of the insertion member 123, applying a force to the bent portion 33c of the locking pin 30 to move to the side opposite to the gap g. As a result, the engaging portion 34 of the locking pin 30 moves forward from the locking portion 13a (in... Figure 16 (From top to bottom) Displacement occurs, and the engagement between the engaging part 34 and the locking part 13a is released. By inserting the member 123 to widen the gap g, the shape of the bent part 33c undergoes plastic deformation and loses the elasticity (locking property) of the locking pin 30, and the engaging part 34 is lifted from the locking part 13a (engagement release process).

[0082] Next, with the insertion member 123 inserted into the gap g, the push rod 131 is activated, causing the push rod 131 to move forward in the forward-backward direction from the initial position and abut against the engaging part 34 of the locking pin 30, separating the locking pin 30, the main body 10 and the pull tab 40 (separation process).

[0083] Next, the insertion member 123 in the abutment portion 125B is reset to its initial position. Simultaneously, the push rod 131 is moved further forward. This pushes the locking pin 30 forward, causing the locking pin 30 and the pull tab 40 to fall downwards towards the retraction portion 140 (first falling step).

[0084] Next, the main body positioning stop 127 is released. As a result, the main body 10 falls downward to the retraction section 140 (second falling process).

[0085] As described above, in this invention, firstly, the engagement of the locking pin 30's engaging portion 34 with the guide post 13's locking portion 13a is released at the engaging release portions 120 and 120B. Then, the main body 10, the locking pin 30, and the pull tab 40 are separated using the separating portion 130. Therefore, the metal materials such as the main body 10 and the locking pin 30 do not mix, and SL1 can be separated without high pressure.
