Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic slider insertion device for a slide fastener that automatically inserts a slider into a gap portion of a slide fastener in which interlocking teeth are continuously formed.

Conventionally, inserting a slider into a slide fastener had to be done manually.

However, this resulted in high labor costs, low throughput, large variations in productivity, difficult production management and quality control, and high product costs.

The present invention automatically performs all of the slider insertion operations of the slide fastener, thereby increasing and stabilizing productivity.
The aim is to reduce costs by saving resources and labor, as well as improving quality and reducing running costs.

This will be explained with reference to the diagram.

In FIG. 1, 30 is a slide fastener, and the tape cord 2 of the tape 1 has hook teeth 5 formed thereon.

3 is the head of the tooth, and 4 is the leg of the tooth. 301 indicates a stringer on one side of the slide fastener.

Reference numeral 6 denotes a gap in which the fastening teeth 5 are removed at intervals of a certain length of the slide fastener 30, and 7 is a slider, with fastening tooth guide portions 8, 8 formed at the rear thereof, and fastening tooth engaging portions 9 formed at the front thereof. Ru.

Then, the engagement teeth 5.5 of the upper and lower opposed IJ fingers 30', 30' are inserted into the slider 7.

In FIGS. 2 and 3, a indicates a slide fastener release portion that disengages the slide fastener 30 that has been guided while being engaged, and b indicates the slide fastener 30 that has been separated.
C is a supply insertion part of the slider, and d is a take-off part of the slide fastener 30.

In the slide fastener separation part a, 10 is a guide, and 11 is a separation frame for disengaging the meshed slide fasteners 30.

In the guiding part, reference numerals 14 and 14' designate moving guides that are provided opposite to the take-off line of the slide fastener 30 with the line in between.

The moving guides 14, 14' are shown in detail in FIGS. 4, 7 to 9.

That is, the guide has insertion grooves 32 and 32' into which each stringer 30' of the slide fastener 30 is inserted, and on the opposing head side there is a hook tooth guide groove 12 into which the hook teeth 5 are fitted and guided. 12' is provided.

The front end exits of the coupling tooth guide grooves 12 and 12' have a guiding surface 13a that exactly matches the lower end surface 41 (see FIG. 7 or 8) of the coupling tooth leg portion 4 of the coupling tooth 5 on which it is attached to the tape 1. The upper surface of the engagement tooth push-in legs 13, 13' is formed.

As shown in FIG.
6 and 17, and the mounting plates 19 and 19 are inserted along this guide shaft 18.
The movement guide 14.14 is movable.

Further, as shown in FIG. 5, the main body of the guide cylinder 20 is attached to one mounting plate 191, and the guide cylinder 20
The movable guide 14 is fixed to each mounting plate 19' and 19 with its double inner and outer rond ends, respectively, and is attached to each mounting plate 19 and 19' by the operation of a guide cylinder 20.
, 14' can move toward or away from each other.

As shown in FIGS. 3 and 4, 15 is a cam whose tip end faces the toothed guide groove 121 of one of the moving guides 141, and the rear end of the cam 15 is engageable with the limit switch LS. be.

This limit switch LS is fixed to the bracket 16.

In the slider supply insertion section C, reference numeral 21 denotes a slider chute that supplies the slider 7, and the slider 7, together with its inclined surface (see Fig. 6), is moved onto the clamp block 24 by a vibration device or a cylinder (not shown). One piece will be sent to.

At the tip of the chute 21 is a slip prevention part 23 for the slider 7.
form.

22 is a guide block of the clamp block 24.

A clamp cylinder 27 is fixed by a cylinder mounting plate 26 attached to the bracket 25, as shown in FIG.

A clamp block 24 is attached to the cylinder rond.

The clamp block 24 is normally attached to the slider chute 2.
It is at the same height as the first surface, and when necessary, by operating the same cylinder 27,
A clamp bolt 28 rises to the position of the take-off line of the slide fastener 30 and is fixed to the upper part with a bracket 25.
The slider 7 is clamped between.

(See FIG. 11) In the take-off section d, reference numeral 29 is a take-off roller that takes off the slide fastener 30 at fixed length intervals.

Note that driving means such as a solenoid or a motor may be used in place of the guide cylinder 20, clamp cylinder 27, etc.

The action and effect will be explained.

The slide fastener 30, which is continuously fed with the engagement teeth 5, 5 engaged, passes through the guide 10 at the slide fastener separation section a, and is disengaged by the separation rod 11.

Each stringer 301°30 of the slide fastener 30
1 is a corresponding moving guide 14 in the guiding part.
, 14', and the fitting tooth 5 is fitted into the fitting tooth guide groove 12, 12' and guided forward.

Then, when the five rows of fastening teeth of the slide fastener 30 are cut and the gap 6 is reached, the rear fastening teeth 5 at the gap 6 section are cut.
The cam 15 senses the position of the limit switch L.
S is activated to stop the rotation of the take-up roller 29 of the take-off section d.

At the same time, the clamp cylinder 27 in the slider supply insertion section C operates, lifts up the slider 7 that was already waiting on the clamp block 24, and places it between the clamp bolt 28 at the position of the take-off line of the slide fastener 30. Clamp this.

At this time, the position of the slider 7 is adjusted to the position of the stringer 3 of the slide fastener 30, as shown in FIGS. 7 and 11.
This means that it is placed in 6 parts of the gap between 0' and 30'.

Then, the guide cylinder 20 in the guide section operates,
The movement guide 14.14', as shown in FIG.
Lean on each other.

and the guide groove 12.12' of the moving guide 14.14'.
The inner teeth 5, 5 are the inner teeth guide portions 8, 8 of the slider 7.
matches the position of

Then, when the slide fastener 30 is pulled up again by the operation of the take-up roller 29 of the take-up part d, the guide groove 12.12'
At the exit of the inner fitting tooth 5, the lower end surface 41 of the fitting tooth leg portion 4 is guided by the guide surface 13a of the fitting tooth pushing leg 13, 13', and the fitting tooth 5 remains as it is at the fitting tooth guide portion 8 of the slider 7. ,8
to go into.

The locking tooth 5 is reliably fed into the slider T by the pressing by the guide surface 13a of the locking tooth pushing portions 13 and 13' and by the pulling force of the slide fastener 30.

Each stringer 30',
The interlocking teeth 5, 5 of 30' are meshed again.

Then, before the next gap 6 reaches the cam 16,
Clamp block 24 and moving guides 14, 14'
is returned to its original position by the operation of a timer or limit switch, and the next one is placed on the crank block 24.
sliders 7 are provided.

Such operations are repeated one after another.

According to the present invention, it is possible to completely automate the complicated operations that conventionally relied on human hands, which saves labor and increases productivity.It also facilitates production management with stable production volume, which in turn , product costs can be lowered.

In addition, automatic high-speed processing becomes possible, greatly increasing production volume, and greatly reducing manpower, reducing work space and
The number of incidental facilities is also reduced, and management costs can also be reduced.

Furthermore, automation with other equipment becomes easy, and integrated automatic production of slide fasteners becomes possible.
