Description

[Detailed description of the invention] This invention relates to a slide fastener fastener attaching machine that is mainly used by sewing manufacturers to attach top or bottom fasteners to a fastener chain on a tabletop. The purpose is to provide a fastener attaching machine that is lightweight and compact so that it can be easily installed on a workbench, provides strong crimping force, and facilitates fastener attachment work. It's about doing.

When sewing manufacturers attach slide fasteners to clothing, for example, they may directly attach an existing completed slide fastener, but generally they cut a long fastener chain to a predetermined length. After the chain is sewn onto the object, a stopper, a slider, etc. are attached to create a completed slide fastener, so a stopper attachment machine, a slider threading tool, etc. are required. Therefore, conventionally, like a stapler,
There is a model in which the fastener is pushed down with a punch and then bent and crimped with a die, but this is done manually, and a model in which the fastener is driven by power is constructed almost the same as a press. However, it had the disadvantage of being large and expensive.

This invention was developed in response to these drawbacks, and is characterized by a stapler-shaped punch driven by a solenoid and a space created around the die.

Hereinafter, an embodiment of this invention will be explained in detail with reference to the drawings. A bracket 2 is fixed to one end of the base 1, a solenoid 3 is provided as close to the bracket 2 as possible, and the base 1 is attached to the base 1. A column 4 is set up at the other end with a space between it and the solenoid 3, a die holder 5 is fixed to the column 4 with a screw so that it can be adjusted up and down, and a die 6 is detachably attached to the top surface of the die holder 5. In addition, a swinging arm 8 with a punch and a rod-shaped holder 9 with a groove-shaped cross section are mounted on a pivot shaft 7 supported on a bracket 2, and a punch 10 is mounted with the swinging arm 8 on top.
are pivotably supported in a state where they face the die 6, respectively, and a spring 11 is interposed between the tips of the swing arm 8 and the holder 9 to maintain a distance between the swing arm 8 and the holder 9. , a U-shaped hanger 12 is provided on the swinging arm 8, on which the holder 9 is supported, the swinging arm 8 and the plunger of the solenoid 3 are connected by a connecting rod 13, and the base 1
The bracket 2 is provided with a return spring 14 that urges the swinging arm 8 upward, and the bracket 2 is
A stopper 15 that restricts the upper limit of the swing arm 8
In addition to protrudingly provided, a screw 16 is provided on the hanger 12 to adjust the distance between the swing arm 8 and the holder 9. Further, a magazine 17 for storing fasteners S in parallel is slidably fitted in the holder 9, a punch guide 18 is provided at the tip of the magazine 17, and a feeder 19 feeds the fasteners S toward the punch guide 18. The feeder 19 has a stopper push piece 20 slidably provided in the magazine 17, and a guide 21 that covers the magazine 17 is attached to the holder 9, and a long hole 22 is bored in the guide 21. , a part of the stopper pusher piece 20 is inserted into this long hole 22, the last stopper S is supplied to the punch guide 18, further sliding is controlled, and the stopper pusher piece 20 is attached to the elongated hole 22. A spring 23 is guided rearward via a roller 24 provided at the tip of the holder 9 and fixed to the swing arm 8. Furthermore,
A lever 2 having a claw piece 25 at the rear end of the holder 9
6, the magazine 17 can be pulled out by engaging the claw piece 25 with the magazine 17 and removing it.

In addition, the solenoid 3 is a small and narrow one that operates with a 100V power supply.
A 200V power supply is applied to create a strong suction force, but the coil may overheat and be damaged.
A safety device is provided to cut off the power in a bimetallic manner upon detection by a temperature sensing element, and the solenoid 3 is connected to a power terminal 28 that can withstand a voltage higher than its rated drive voltage.

In the figure, 27 is an auxiliary spring that pulls the holder 9 downward, 29 is a foot switch terminal, 32 is a cover, 33 is a spring for preventing aftershock of the swing arm 8 and holder 9, and an auxiliary rod 3 is located in front of the base 1.
0 may be made to protrude, and a slider passing jig 31 may be provided thereon so as to be freely adjustable in forward and backward movement.

This invention has the above structure, and the magazine 17
If the stopper S is placed in and the solenoid 3 is driven,
At the same time as the swinging arm 8 connected to the solenoid 3 descends, since the spring 11 is interposed between the swinging arm 8 and the holder 9, the holder 9 also descends while maintaining the distance from the swinging arm 8, and the punch guide Even after the 18 hits the die 6, the swinging arm 8
continues to descend, so the spring 11 that maintains the distance
is compressed, and the punch 10 hanging from the swinging arm 8 descends inside the punch guide 18 and the stopper S
is pushed out toward the die 6 and tightened. When the solenoid 3 is switched off after crimping is completed, the punch 10 begins to rise due to the repulsive force of the spring 11 that maintains the distance, and further due to the repulsive force of the return spring 14 applied to the swing arm 8. Holder 9
It also rises and returns to its original position. Therefore, when attaching the fastener S to the fastener chain f, the fastener chain f should be placed on the die 6.
After placing the specified part, apply a voltage higher than the rated voltage to activate the solenoid 3 and attach the stopper S.
Then just turn off the switch.

As described above, the slide fastener fastener attaching machine according to this invention provides a space between the bracket that pivotally supports the swinging arm with a punch and the support that has the die, and the solenoid that drives the swinging arm is Because it is small and placed as close to the bracket as possible, a large space is maintained between the column and the solenoid, and when attaching the fastener to the fastener chain sewn to the adherend, it is possible to Since a part of the fastener chain can be placed hanging in the space between the support and the solenoid, the fastener chain's stopper attachment position can be placed on the die comfortably and stably, and it can be held correctly until the stopper is hit. It is something. Furthermore, the solenoid,
It has a power terminal that can withstand a voltage higher than the rated drive voltage, and a safety device that detects overheating and shuts off the power, so the solenoid can be driven at a high voltage and has a large initial torque. Even though it is small, a strong crimping force can be obtained, and fasteners can be reliably attached even though the entire machine is downsized.
