Description

  In the present invention, a synthetic resin rivet member and a male or female synthetic resin fitting member in which a through hole for inserting a projection of the rivet member is disposed on both sides of the sheet-like member. Then, the protrusion of the rivet member is pierced into the sheet-like member and inserted into the through hole of the fitting member, and the distal end portion of the protrusion is struck and subjected to diameter expansion deformation (flanging), whereby the rivet member and the fitting are The present invention relates to a snap fastener attaching machine in which a fitting member and a sheet-like member are clamped and clamped.

  For example, a receiving tool that supports a rivet member made of synthetic resin so that the protrusions face upward, a driving tool that can be moved up and down disposed above the receiving tool, and a protrusion of the rivet member are inserted in the center. A first hopper that accommodates a synthetic resin fitting member having a through-hole formed therein, a second hopper that accommodates a rivet member, and a first chute that feeds down the fitting member that is fed from the first hopper A rivet that is supplied to the lower end of the second chute using the second chute that is supplied from the second hopper and the fitting member that is supplied to the lower end of the first chute. And a pusher capable of reciprocating in the front-rear direction having a two-stage pressing plate portion for feeding members to the receiving device, respectively, A movable driving tool body that can be moved up and down, an openable upper chuck for holding a fitting member that is slidable in the vertical direction on the driving tool body, and a vertically slidable and energizing force with respect to the driving tool body A cylindrical shaft-shaped guide punch urged downward by the means, and a caulking punch disposed on the inner side of the guide punch and fixed to the driving tool main body, the receiving tool receiving the rivet member And a lower chuck that can be opened and closed for positioning a sheet-like member configured to descend synchronously with the descent of the driving tool at a predetermined timing, and a sheet-like shape between the receiving tool and the driving tool By lowering the driving tool with the member interposed, the fitting member is pushed down by the guide punch, and the protrusion of the rivet member is inserted into the sheet-like member and fitted. Snap fastener attachment that is inserted into the through-hole of the material, hits the tip of the protrusion with the caulking punch, and is deformed to expand the diameter, and the rivet member and the fitting member are crimped to the sheet-like member The machine is already known from US Pat.

  In this type of snap fastener attaching machine, as described in Patent Document 1, for example, a sheet-like member such as an edge of the front body of clothing is interposed between the receiving tool and the driving tool. When the pedal is depressed, the driving tool driven by the motor output through the one-rotation clutch is lowered, and the driving tool is moved up and down after the rivet member and the fitting member are clamped and held between the sheet-like members. Ascending and returning to the upper end of the stroke, the next rivet member and fitting member are automatically fed to the receiving tool and the driving tool by the pusher, so that the rivet member and the fitting member are manually supplied to the receiving tool and the driving tool. Compared to a semi-automatic machine, there is an advantage that the snap fastener can be attached efficiently.

  By the way, even if it is a single garment, not all the snap fasteners attached to it are the same. For example, according to the color pattern of the garment, only the snap fastener at a specific position and the color of the rivet member are the same as the garment. May change to the same color. Also, even in a single garment, it is common for the end to have a number of pieces of fabric piled up to increase the thickness, and only the snap fastener attached to such a thick part has a long protrusion. May be used.

  In such a case, conventionally, the snap fastener attaching work is left only at the location where the rivet member having a different color and protrusion length is used, and the attaching work of the same snap fastener to all clothes is completed at an appropriate time, for example. After that, all the rivet members remaining in the second hopper and the second chute of the snap fastener attaching machine were taken out and replaced with another rivet member having a different color and protrusion length, and the snap fastener attaching work was left. Although the snap fastener is attached to the location, the rivet member remaining in the second chute cannot be visually confirmed, so that the rivet member is unexpectedly left in the second chute for some reason, such as a sag with the chute inner surface. As a result, the next snap fastener mounting operation can be resumed. There was.

  As a result, caulking failure due to insufficient protrusion length or color difference of the rivet member will occur. Using tools, etc., the snap fastener will be broken to separate it from the clothing, and the installation work will be performed again. The troublesome work of reworking was required.

  In addition, a male fitting member is accommodated in one of the two hoppers, a female fitting member is accommodated in the other, and guide grooves in the chute are respectively provided in the two chutes connected to both hoppers. In a snap fastener mounting machine of a type in which a shutter operating lever for opening and closing is provided, a rivet member is manually supplied to a receiving tool, and a male fitting member and a female fitting member are selectively automatically supplied to a driving tool. However, if either the male fitting member or the female fitting member is unexpectedly left in the chute for some reason, the same problem is caused.

The first and second hoppers 12a and 12b rotate intermittently in one direction by the reciprocating swing of the swing arms 17a and 17b, and the intermittently rotates the fitting member B from the first hopper 12a in a fixed posture. The rivet member A is extended from the second hopper 12b in a fixed posture. 20a is a member supply port for fitting, and 20b is a rivet member supply port.

  Reference numeral 21 shown in FIG. 3 denotes a pusher that can reciprocate in the front-rear direction having upper and lower pressing plate portions 21a and 21b, and is made of a metal plate having a predetermined thickness and is supplied to the lower end of the first chute 13a. The fitted member B is fed to the driving tool 9 by the upper pressing plate portion 21a, and the rivet member A fed down to the lower end of the second chute 13b is transferred to the receiving device 8 by the lower pressing plate portion 21b. It is configured to send in.

  As shown in FIG. 3, the driving tool 9 is mounted by an elevating drive means (not described) driven by an elevating drive means (not shown), and is mounted on the driving tool body 22 so as to be vertically slidable. The upper chuck 23 that can be opened and closed for holding the fitting member, and a biasing means that is slidable in the vertical direction with respect to the driving tool main body 22 and that is interposed between the driving tool main body 22 and attached downward is applied. It includes a biased cylindrical shaft-shaped guide punch 25 and a caulking punch 26 that is disposed inside the guide punch 26 and is fixed to the driving tool main body 22 and moves up and down integrally with the driving tool main body 22. A spring 27 biases the upper chuck 23 in a closed state.

  The guide punch 25 and the caulking punch 26 are attached to the driving tool main body 22 so as to be detachable and replaceable. That is, the guide punch 25 and the caulking punch 26 have shapes suitable for the case where the fitting member B is male (for male snap) and the case where the fitting member B is female (for female snap). Are prepared in advance, and are exchanged depending on whether the fitting member B is male or female. Reference numeral 28 denotes a retaining ring for the guide punch 25, which is screwed and fixed to the lower end of the driving tool main body 22.

  The upper chuck 23 elastically holds the fitting member B fed by the upper pressing plate portion 21 a of the pusher 21 so as not to fall by its own weight, and is pushed down by the guide punch 25 of the driving tool 9. The fitting member B is pushed right and left against the spring 27 to release the holding state of the fitting member B. 29 is a pressing spring for holding the upper chuck 23 against the driving tool body 22 by friction force by pressing the upper chuck 23 against the front surface of the driving tool body 22, 30 is a nut for adjusting the spring pressure, and 31 is a driving tool body. 22 is a stopper that defines the upper limit position of the upper chuck 23 relative to 22.

  The receiving device 8 includes a receiving base 32 on which the rivet member A is placed, and an openable / closable lower chuck 33 for positioning the rivet member which is configured to be synchronized with the lowering of the driving tool 9 at a predetermined timing. It has. The lower chuck 33 is composed of a pair of left and right members biased in a closed state by a spring 34, and a rivet member A that is fed by a pressing plate portion 21 b on the lower stage of the pusher 21 to opposite sides of the pair of left and right members. And a circular hole located at the end of the guide groove (directly above the cradle 32), and the inner diameter of the circular hole is larger than the diameter of the head of the rivet member A. It has a slightly larger diameter. Reference numeral 35 denotes a guide plate for guiding the vertical movement of the lower chuck 33, which is positioned on the lower front surface of the block-shaped frame 4 by two pins 36 and fixed by bolts 37.

  Lower ends of the pair of left and right members of the lower chuck 33 are pivotally attached to a front end of the swing arm 39 by a pin 40 that can be inserted and removed. In contrast, it is configured to descend while opening left and right.

  Therefore, the upper chuck 23 holds the fitting member B by lowering the driving tool 9 with the sheet-like member such as the edge of clothes interposed between the receiving tool 8 and the driving tool 9. The guide punch 24 pushes down the fitting member B by further lowering the driving tool main body 22 even after the upper chuck 23 comes into contact with the sheet-like member supported by the lower chuck 33. Therefore, the protrusion of the rivet member A passes through the sheet-like member and is inserted into the through hole of the fitting member B.

  In this state, the guide punch 24 and the caulking punch 25 continue to descend further, and even after the lowering of the guide punch 24 is blocked by the cradle 32, the caulking punch 25 descends with respect to the guide punch 24, so that the caulking punch 25 projects. The tip portion is hit and deformed to expand, and the rivet member A and the fitting member B are caulked and stopped in a state where the sheet-like member is sandwiched.

  In FIG. 4, the male fitting member B is shown as the fitting member B. However, the female fitting member B can be obtained by replacing the guide punch 25 and the caulking punch 26 with those for female snapping. And the rivet member A can be caulked. That is, the snap fastener is made of four members: a rivet member A and a male fitting member B that form a male snap, and a rivet member A and a female fitting member B that form a female snap. By replacing the guide punch 25 and the caulking punch 26, either a male snap or a female snap can be produced.

  Reference numeral 70 shown in FIG. 1 denotes a work table on which a sheet-like member is placed, and is detachably attached to the main body frame 1. On the work table 70, a positioning rising piece 71 capable of abutting the rear end edge of the sheet-like member is mounted in a state in which the position can be adjusted back and forth by a butterfly bolt and a nut. Reference numeral 72 shown in FIG. 3 denotes a marking projector disposed behind the driving tool 9, and when the driving tool 9 is at the upper end of the lifting stroke, a predetermined position of the sheet-like member (the protrusion of the rivet member A on the sheet-like member). (A position directly above) is irradiated with a cross-shaped spotlight.

  In the vicinity of the lower end of the second chute 13b, a stopper 76 is pivotally attached via a bracket screwed to the lower surface of the rear chute member 130B. The stopper 76 is rotated around a vertical bolt 77 serving as a fulcrum, thereby preventing the outflow from entering between the rivet member A located at the lowermost end and the second rivet member A from the bottom (FIG. 6). Reference) and an outflow allowable state (see FIG. 5) that has been withdrawn from between the rivet members A and A.

  Therefore, immediately before attaching the previous snap fastener to be changed to the rivet member A of a different color or the rivet member A having a different projection length, the stopper 76 that was in the outflow allowable state is switched to the outflow prevention state, and in this state, When the snap fastener is attached, there is no outflow of the rivet member A from the second chute 13b. Therefore, the upper pressing plate portion 21a pushes the fitting member B into the driving tool 9 as shown in FIG. As shown in FIG. 6, the lower pressing plate portion 21 b is fed to the receiver 8 and the rivet member is not supported by the receiver 8. Therefore, it is not necessary to take out an unnecessary rivet member from the receiver 8, and the rivet member A having a different color and protrusion lengths H and h can be easily and quickly loaded into the receiver 8 manually (tweezers).

  Reference numeral 78 denotes a coil spring that presses the stopper 76 and fixes it in the above two states by frictional force, and 79 is a spring pressure adjusting nut. The stopper 76 is formed with an operation opening 76a for locking the fingertip. 80a is a lid member at the tip of the first chute 13a, and 80b is a lid member at the tip of the second chute 13b. These lid members 80a and 80b are removed to open the tips of the first and second chutes 13a and 13b. By doing so, the fitting member B and the rivet member A inside the chute can be extracted. Reference numeral 81 denotes a fixing bolt for the lid member 80a, 82 denotes a fixing plate spring for the lid member 80b, and 83 denotes a positioning projection.

  According to the above configuration, since the first chute 13a and the second chute 13b are divided into two in the width direction, that is, each of the first chute 13a and the second chute 13b, Since the first half chute member 130A and the second half chute member 130B are divided and connected to each other, the guide chute corresponding to the cross-sectional shape of the fitting member and the rivet member is formed on the first chute and the second chute. The first chute 13a and the second chute 13b can be easily manufactured as compared with the case where the first chute 13a and the second chute 13b are connected to each other. Of the chute members 130B, since the first half side chute member 130A is made of a transparent material, the fitting portion remaining in the first chute 13a Visible rivets member A remaining in the B or the second chute 13b.

  Particularly, since the rear half chute members 130B of the first chute 13a and the second chute 13b are made of metal, even if the front half chute member 130A is made of a transparent synthetic resin, the metal latter half side connected thereto is used. The chute member 130B serves as a reinforcing member, and deformation due to temperature change or the like of the transparent synthetic resin first half chute member 130A can be prevented. Further, if each of the first half chute member 130A and the second half chute member 130B is made of a transparent synthetic resin, it becomes difficult to process the screw holes (female screw-shaped holes) or to connect them by screwing. In this embodiment, Since the rear half chute member 130B is made of metal, the screw holes 131 are processed in the rear half chute member 130B, and through holes corresponding to the first half chute member 130A made of transparent synthetic resin are formed.
