Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method and apparatus for picking out clothing parts such as collars and cufflinks one by one from a stack of many collars and cufflinks.

[Conventional technology]

In order to sew clothing such as dress shirts, clothing components such as collars and cuffs are usually produced in large quantities separately, and these parts are assembled to create the finished clothing. Therefore, when automatically sewing clothing, it is important to automatically take out many parts (collars, cufflinks, etc.) one by one from a stack of parts (collars, cufflinks, etc.) stacked in one place. Due to the friction that occurs between the pieces of fabric, several pieces of fabric are picked up and removed at once, making it impossible to automate the removal process.

In order to avoid this problem, various take-out devices have been devised, but these devices have the drawback of damaging products such as collars and cuffs, and being unstable in the number of sheets that can be taken out, making it impossible to always take out one piece at a time. was there.

[Problem that the invention seeks to solve]

In view of the foregoing, the present invention provides a collar that can be used without damaging the product.
An object of the present invention is to provide a method and device for taking out clothing parts such as cufflinks one by one.

[Means for solving problems]

The present inventor conducted a seeding experiment regarding the frictional force generated on the contact surfaces when fabrics in contact with each other are moved relative to each other, and as a result, the following two characteristics were discovered.

As shown in figure fljfi1, the frictional force F when two pieces of cloth (c) (d) that are in contact with each other with their weave directions α and b aligned are moved relative to each other in the weave direction (arrow C) is: As shown in Fig. 2, the weave directions α and b do not match,
For example, the frictional force F in the case of relatively moving (arrow g) the cloth (4(d)) that is in contact with each other with a 45 degree deviation is larger.

(11) As shown in Figure 3, fabric (c) (ct) (h
)..., place a friction disk (L) on top of it, apply a force P to this friction disk (B) so that the surface pressure is 15 grams or more per square glue, then stack the fabric ( C) (d)
When a turning force M is applied parallel to (A), etc., the contact surface (rL) between the first fabric (C) and the second fabric (d,)
The friction torque generated on the friction surface between the second and third sheets (
It is smaller than the friction torque generated in q).

The above characteristic (1) is that the state of entanglement (8) of the fibers of the twisted yarns that make up the fabric changes depending on the direction of the weave of the stacked fabrics, and characteristic (11) is that the state of entanglement (8. Since the fabric (C) is compressed more strongly than the second and subsequent fabrics (ct), the intertwining of the fibers between the fabrics (C) (=') is stronger than that between the fabrics (ct) and (A). It is also estimated that the

The present invention utilizes the above-mentioned characteristics of friction between fabrics, and presses a member having a non-slip bottom surface onto the top of a stacked bundle of fabrics, and rotates the bottom surface parallel to the plane of the fabrics. When the above operation is performed, only the uppermost clothing part turns in the horizontal plane, so the turned part can be pulled out to the side, and only the pulled out part can be taken out independently. This has advantages such as facilitating automatic sewing.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. Fourth
The figure shows an example of a device for carrying out the method of the present invention, in which a take-out device places a bundle (2) of a large number of stacked strip-shaped cuffs (1) and a screw mechanism (3). A base plate (4) which can be moved vertically through It consists of a disc-shaped member (7) that is rotated in a horizontal plane.

Bottom surface (8) of member (7) and top surface (9) of plywood (4)
are constructed parallel to each other and flat, and anti-slip QQI 117J made of rubber or the like is attached.

The reference numeral (131) is a take-out arm that is placed at the same height as the top cuff (1) and is reciprocated in the horizontal direction by a drive device (not shown). An occlusal mechanism a9 that grips the is attached.

Next, the handling procedure and operation of this device will be explained.

First, place the bundle of cufflinks (2) stacked in the same direction on the plywood board (4) in the lowest position, and drive the cylinder (5) to stack the bundle of cufflinks (2) on the bottom surface (8) of the member (7). ) downwards (arrow P). At this time, the surface pressure of the member (7) is approximately 15 grams or more per square glue. Next, the swing arm (6) is driven in the direction of the arrow to swing the member (7) approximately 45 degrees in the horizontal plane (see imaginary line).

After performing the above operations, the top cuff (1) becomes member (7).
and turn in the direction of arrow ε (see imaginary line).

Here, pull up the member (7) slightly to loosen the pressure on the cuff (1) and drive the extraction arm 03 (arrow t).
Then, actuate the bite mechanism α9 to grab the rotated uppermost cuff (1), and drive the take-out arm OJ again to release the cuff (1).
) to the side (arrow U).

When pulling out the top cuff (1), pull out the top cuff (
Since the weave directions of the fabrics of 1) and the second cufflink are different from each other, only the top cufflink is taken out, and the second cufflink remains in its original position.

When the top cuff (1) is taken out, the plywood (4) rises by the thickness of one cuff (arrow υ), and the second cuff (1) comes to the top, so repeat the above operation. repeat.

It should be noted that the present invention is not limited only to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

〔Effect of the invention〕

As described above, the method and device for taking out one piece of fabric according to the present invention uses a member having a non-slip bottom surface.
Since it presses against the upper part of the stacked clothing parts and also rotates, it exhibits the following excellent effects.

(i1 Due to the frictional properties of the overlapping fabrics, only the top part can be turned, and the weave of the turned part is angularly shifted from the weave of the second part, so
Only the top part can be easily taken out to the side.

(11) As a result of item (1), the work of taking out each piece from the side is performed smoothly and reliably, so there is no risk of damaging products such as collars and cufflinks.

(m) as a result of paragraph (1), automated sewing of clothing is facilitated;
Work efficiency can be improved.
