DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to an apparatus for manufacturing a reverse opening slide fastener.

b. Prior Art A conventional method for automatically manufacturing a reverse-opening slide fastener is to move a pair of left and right stringers, insert the first slider and second slider in sequence, and then attach a box rod and a butterfly to each stringer. How to attach a rod (for example, JP-A-56-
85301), and as an improvement on this, an insert pin is attached to one stringer before inserting the first slider and the second slider, and after inserting the two sliders,
A method of attaching a box bar to the other stringer (Japanese Patent Application No. 132095/1982) has been proposed by the same applicant, but an apparatus for automatically manufacturing a reverse opening slide fastener has not yet been realized. Previously, the insertion of the slider and the attachment of the insert pin and box pin had to be done individually by hand using dedicated machines. In manufacturing a reverse-opening slide fastener for right-hand insertion and a reverse-opening slide fastener for left-hand insertion, they were manufactured separately using jigs for right-hand and left-hand insertion.

c. Purpose of the Invention The present invention is a device that can automatically manufacture reverse-opening slide fasteners for right-handed and left-handed reverse-opening slide fasteners using a single machine, which has conventionally been done manually. The object of the present invention is to provide an apparatus that can freely select and automatically manufacture reverse-opening slide fasteners using one machine.

d. Structure of the Invention The structure of the present invention is as described in the claims, and includes an insert pin attachment unit A, a first slider attachment unit B, a second slider attachment unit C, and a box on the stringer transfer line. The rod mounting units D are arranged in sequence, and parts feeders for right and left insertion are provided in the insert pin mounting unit A and the box rod mounting unit D, respectively, and two insert pin holding holes and two box rods are provided. The structure is such that a right-hand insertion pin, box rod, or left-hand insertion pin and box rod are selectively supplied to the holding hole according to a command, and are attached to a predetermined stringer, so that each unit is automatically connected at a specified time. The present invention will be described in more detail with reference to the illustrated embodiment.The reverse opening slide fastener is a conventional slider 24 as shown in FIG. In addition, a slider 25 whose internal structure is reversed (inverted box slider) is installed, and can be used for right-handed or left-handed inserts depending on which side of the stringer the box bar 41 with a stopper is attached to. There are two types of reverse-opening slide fasteners. Figure 12 A shows when attached to clothing.
Because the stringer 2 on the right hand side is inserted, it is called a reverse slide fastener for right-hand insertion.
It is mainly used in Japan, and since the stringer 1 on the left hand side is also inserted in the one shown in Figure 12, it is called a reverse-opening slide fastener for left-hand insertion, and is mainly used in the United States. It is something. Therefore, since the attachment positions of the insert pin and the box rod are different, separate jigs are required, but in the present invention, a reverse opening slide fastener can be automatically manufactured using a single device. In addition, it is possible to freely select whether it is for right-handed or left-handed attachment and automatically manufacture it.

The insert pin holder 19 has an insert pin holding member 20 that forms an insert pin holding hole 22 and a notch punch 21 that are vertically supported. It is slidably provided. As shown in Fig. 6, two insert pin holding holes 22 are provided corresponding to the left and right stringers, and depending on the instruction for right-hand or left-hand insertion, either one of the insert pin holding holes 22 is provided.
2 is supplied with an insert pin 18 and attached to one of the stringers. Figure 3 shows stringer 2 and butterfly pin 1
8 is installed (as the stringer is installed with its back facing up, this is an example for right-hand insertion). Predetermined butterfly pin 18
The insert pin holder 19, which has received the stringer from the chute 17 into the predetermined insert pin holding hole 22, waits at the position shown by the solid line in FIG. The die 23 of the die device rises and pushes the insert pin holding member 20 upward, and at the same time, the notch punch 2
1 is pushed down by means not shown, and the insert pin 1
8 is caulked and attached to the stringer. After that, the die 23 is lowered, the insert pin holding member 20 is pushed down by other means not shown, and the insert pin holding hole 22 is opened widely, so that the stringer with the insert pin attached can easily pass therethrough. . After one reverse-opening slide fastener is completed, the insert pin holding hole returns to its original state and preparations are made for attaching the next insert pin.

Next, the slider mounting unit will be explained. Slider mounting units include a first slider mounting unit B and a second slider mounting unit C, as shown in FIGS. As shown in Figures 1 and 2, although the slider is supplied from the opposite direction, the structure of the mounting unit is the same, so we will explain the structure of the mounting unit B of the first slider, and then explain the mounting of the second slider. A description of unit C will be omitted.

As shown in FIG. 7, the first slider mounting unit B receives the slider 24 from the slider parts feeder 26, transports it into the stringer transport path, and inserts it into the stringer. and a slider holder 29 that holds the slider 24 between the transfer holder 28 and the chute 27 that receives the slider, as shown by the chain line in FIG. It is equipped with a clamper that grips and transports the slider. A slider holder 29 is provided below the transfer holder 28, and a stopper block 30 and a locking block 31, which are moved up and down by a piston, are slidably housed therein. At the tip of the stopper block 30, a slider 2 is inserted between the clamper of the transfer holder 28.
A mounting surface for holding the stringer 4 and a portion for blocking the tip of the stringer are provided. The locking block 31 has a locking lever 3 that engages with a pull 33 of the slider 24.

When the slider 24 is inserted into the stringer, the stopper block 30 is lowered, the locking lever 32 is removed from the handle 33, and the left and right stringers are moved inside the slider held by the clamper of the transfer holder 28 and the tip of the locking block. are transferred and properly engaged with the slider before being sent to the next process. However, in the second slider mounting unit C, since the internal structure of the slider is different, as the stringers are transferred, the meshed stringers are separated and sent to the next process. When the finishing process is completed and the upper stopper fixed to the rear end of the fastener element reaches the end, the locking block 31 is lowered and the transfer holder 28 is ready for the installation of the next slider.

Finally, box bar mounting unit D will be explained.
The box rod mounting unit D is provided with right-hand and left-hand box rod parts feeders 38 and 39 that sandwich the stringer transfer line, and can be selected by command in the same way as the insert rod parts feeders 15 and 16. The structure is such that the necessary box rods 41 are supplied. Since the attachment positions of the insert pin and box rod to the stringer are opposite to each other, the box rod parts feeder 39 for right-hand insertion and the box rod parts feeder 38 for left-hand insertion are required.
As shown in FIG. 1, the insert pin parts feeder is located in the opposite position. Box bar mounting unit D
As shown in FIG. 8, the box bar holder 34 is composed of a box bar holder 34 and a lower die device, and the box bar holder 34 is located at the feeding position of the chute 35 of the box bar parts feeder.
It is pivotally supported so that it can swing between the box and bar mounting positions.
Since two sliders are already attached to the stringer being transferred, it cannot pass through the box bar holding hole 40 after the box bar is attached, so the box bar holder 34 is retracted above the transfer line and at the same time the box bar is The box rod parts feeder is placed above the transfer exit side of the stringer so that it can be replenished. Therefore, since the direction in which the stringer is inserted into the box bar holding hole for attaching the box bar and the direction in which the box bar is supplied are opposite to each other, the two stringers formed at the tip of the box bar holder 34 are A lift gate 42 and a shutter 43 are provided in the box bar holding hole 40 to hold the box bar in a predetermined position. The lifting gate 42 is configured to hold the box bar 4 supplied to the box bar holding hole 40.
It prevents the shutter 4 from falling and guides the tip of the stringer to be inserted.

A stopper 46 is provided near the tip of the shutter 43 in order to keep the box rod holding hole 40 wide open, and when it comes into contact with the base 36 during supply, the stopper 46 comes off and the box rod mounting hole 40 is opened. 40 to its original state. A, B, C, and D in Fig. 10 show the installation order of the box bars. In Fig. 10 A, the box bar holder 34 swings to the supply position, and the stopper 46 and press pin 45 are placed on the base 36 and is pressed,
The stopper 46 comes off and the box bar holding hole 40 returns to its original position, and the shutter 43 is pressed by the tip of the press pin 45 and moves to the right, causing the box bar insertion hole 44 and the box bar holding hole 40 to communicate with each other, and the shutter 35 The box bar 41 has been supplied to the box bar holding hole 40 from above. In FIG. 10, the box bar holder 34 returns to the mounting position, and the stringer S is inserted from the left into the closed shutter 43 and the box bar 41 held by the lift gate 42. To attach the stringer to the stringer, as shown in Fig. 11, the grip base 7 of the gripper mechanism moves left and right to separate the gripped stringer, and the stringer with the insert pin is released from the box rod holder, leaving the stringer without the insert pin attached. This is done by inserting the stringer into the box bar held in the box bar holding hole, and FIG. 11 shows the installation for right-hand insertion. In order to easily take out the stringer with the box bar attached to it from the box bar holding hole 40, the locking lever 47 provided on the die 37 is lowered to pull down the box bar holding member. It has been opened wide. The stringer inserted into the box bar is caulked by the die 37 that has risen from below and the notch punch that has descended within the box bar holder 34. As the die 37 descends, the box bar holding member engaged with the locking lever 47 is pulled down, and the lifting gate 42 is also lowered.
A stopper 46 engages with the box bar holding member to maintain the wide open state. Next, the box bar holder 34
is swung to the position of the chute 35, and the stringer to which the box bar is attached is taken out from the box bar holding hole 40, and transfer by the gripper mechanism is resumed. FIG. 10D shows the state before the box bar holder 34 swings, the stopper 46 comes into contact with the base 36 and comes off, and the press pin 45 comes into contact with the base 36 and is not activated. By repeating such operations, the box rod for right or left insertion selected by the command is supplied to either one of the box rod holding holes 40, and is attached to the tip of the stringer to which no insert pin is attached. .

Finally, after the insert pin, first slider, second slider, and box rod have been attached, the stringer is cut by a cutting unit E having a well-known structure in the space where the element is missing and the length of the final product is predetermined. Then, the desired reverse-opening slide fastener for right-hand insertion or reverse-opening slide fastener for left-hand insertion is sent out from the manufacturing device as a finished product, and a single reverse-opening slide fastener is completed. In addition, the command for right-hand or left-hand insertion is for the butterfly pin,
It is configured to be electrically or mechanically transmitted to each parts feeder for box rods and to supply predetermined parts in synchronization with the operation of each holder.

e Effect of the Invention The device of the present invention is arranged in the order of the insert pin attachment unit, the first slider attachment unit, the second slider attachment unit, and the box rod attachment unit on the stringer transfer line, and in particular the insert pin attachment unit. In the box rod mounting unit, there are insert pin supply chute for right and left insertion, and box rod supply chute for right and left insertion, and the insert pin holder and box rod holder correspond to each stringer. Two holding holes are respectively provided, and each mounting bracket is selectively supplied to each holding hole according to a command for right-hand or left-hand insertion, and is configured to be attached to a predetermined stringer.
