Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a member feeding device used in an automatic press machine or the like.

[Technical background of the invention and its problems]

BACKGROUND ART As a method for manufacturing a large number of parts of the same shape by press working, a method is widely adopted that uses an automatic press machine, feeds a long member into a press section, and sequentially press-works the long members. Conventionally, feeding devices such as gripper feeders and roll feeders have been used to feed parts in this automatic press machine, and these feeding devices sequentially feed a long member, such as a band-shaped member, at a fixed pitch to perform press processing. are doing. However, in this case, if multiple parts could be sent in parallel and pressed at the same time, the productivity would be dramatically improved, and this method would also allow for the simultaneous processing of irregularly shaped parts. By doing so, it becomes possible to shorten mold replacement and setup time, and easily perform production that is suitable for high-mix, low-volume production.

However, in the conventional feeding device, for example, taking an example of a gripper feeder, as shown in FIG. Therefore, it has been difficult to reliably feed multiple members at the same time.

That is, the gripper feeders are used in a pair facing each other so as to be able to grip the member W from both sides, and a plurality (two in the illustrated example) of the pair of facing gripper feeders are installed in the feeding direction of the member W. It is used as To feed the member W, a pair of gripper feeders installed at the rear end of the member W in the feed direction are used as sliding grippers 5 that can freely approach and separate and slide in the feed direction, and a pair of gripper feeders installed at the front end of the member W in the feed direction. As a fixing gripper 6, which approaches and separates the member W at its installation position, when the sliding gripper 5 clamps the member W and feeds it to the position shown by the dashed line in the drawing, the fixing gripper 6 releases the member W. However, when the sliding gripper 5 releases the member W and stops feeding, the method of holding the member W is performed.

Therefore, even with the gripper feeder in which the jaw 3 is fixed to the bracket 1 as described above, when feeding one member W, it is necessary to ensure that it is delivered regardless of the thickness of the member W as shown in Fig. 8A. It can be packed and sent. However, multiple members W arranged in parallel
When feeding the members W at the same time, it is necessary to sandwich the members W as shown in Fig. 8B depending on the difference in the thickness of the members W, the size of the warpage, or the size of the burr of the slit formed in the previous process. There are cases where this is not possible.

[Purpose of invention]

The purpose of this invention is to obtain a feeding device that can simultaneously feed a plurality of members in parallel.

[Summary of the idea]

A swinging fulcrum for swinging the pressing body in a transverse direction perpendicular to the feeding direction of the member is provided between a pressing body such as a jowl or a roll that presses the elongated member and a bracket supporting the pressing body, By configuring this swing fulcrum with an unchanging protrusion that is long in the feeding direction of the member and is integral with the pressing body or the bracket, the pressing body can change its posture freely in response to changes in the shape of the member, etc. It was possible to change to.

[Example of idea]

Hereinafter, this invention will be explained based on examples with reference to the drawings.

FIG. 1 shows a grip feeder that is an embodiment of this invention. This gripper feeder has a bracket 11 on the inside of which a support 10 is mounted, and a jaw 12 supported by the bracket 11. As shown in FIG. 2, this jacket 12 is composed of a stepped plate-like body whose diameter is smaller on the top side than on the bottom side, and on its top surface, an elongated protrusion 13 is formed that crosses the center of the plate-like body. ing. This protrusion 13
has an unchanging shape and is integrally formed with the stepped plate-like body. Furthermore, stepped through holes 14 are provided on both sides of the protrusion 13, as shown in FIG. 3, the diameter of which is larger on the bottom side than on the top side. A concave hole 15 is provided at the tip of the support body 10, which is shallower than the height h of the top of this Jyo 12 and has a larger diameter than the top. It is attached to the bracket 11 by a screw 16 that passes through the through hole 14 and engages with a screw hole formed at the bottom of the recessed hole 15. Around this screw 16, the top height h of the jaw 12 is
A sleeve 17 that is longer than the diameter of the small diameter portion of the through hole 14 and thinner than the diameter of the small diameter portion of the through hole 14 is inserted, and by the insertion of this sleeve 17, the jaw 12 is supported so as to be able to swing freely about the protrusion 13 as a fulcrum. There is. Incidentally, reference numeral 19 denotes a mounting portion consisting of bolts and nuts for mounting the gripper feeder to the drive mechanism.

In this gripper feeder, the longitudinal direction of the protrusion 13 formed on the Jyo 12 coincides with the feeding direction of the member, and the Jyo 12 swings in the transverse direction of the member, which is orthogonal to the member feeding direction, using the protrusion 13 as a swing fulcrum. is movably attached to a drive mechanism.

FIG. 4 shows an example of use in which this gripper feeder is placed upward and faces a conventional gripper feeder to clamp a member W. Like this, Jiyo 12
If you use a gripper feeder that is attached so that it can sing freely, for example, as shown in Figure A,
Even when there is a difference in the thickness of the two members W, the jaw 12 rotates about the protrusion 13 as a fulcrum when pressing the member W, and can reliably hold both the members W. In addition, when transporting one member W by holding it, even if the thickness of the member W differs in the width direction, as shown in Figure B, for example,
This can be held securely. In other words, the conventional grip feeder shown in Fig. 7 alone cannot
Hold the member W as indicated by the broken line 21 in the drawing,
This tends to result in unstable clamping and unstable feeding, but this gripper feeder can reliably clamp the clamp and provide stable feeding by rotating the jaw 12.

Next, other embodiments will be described.

In the above embodiment, a protrusion was provided on the top surface of the jaw to serve as a swinging fulcrum, but as shown in FIG.
A protrusion 13 with a similar unchanged shape is provided on the bottom surface of the concave hole 15 of 0.
may be formed integrally to serve as a swinging fulcrum. The rest of the configuration of this gripper feeder is the same as that of the above embodiment, so the same reference numerals are given and the explanation thereof will be omitted.

FIG. 6 shows an example of application to a roll feeder. This roll feeder has bracket 11
A pair of rolls 24a, 24b rotatably supported between a pair of side plates 23 of this bracket 11.
and has. A hemispherical projection 13 or an unchanging projection 13 having a constant length in the rotational direction of the rolls 24a, 24b is integrally formed at the inner center of the bracket 11. , the member W can be pressed with an arbitrary pressing force.
The upper roll 24a is configured to be in pressure contact with the upper protrusion 13. In addition,
Reference numeral 19 is a mounting portion for mounting the roll feeder to the drive mechanism.

When the roll feeder is configured as described above, the upper roll 24a can be swung within a plane including its rotation axis and the lower roll 24b using the protrusion 13 as a fulcrum, and the member W
can be securely held and sent.

Further, in the roll feeder described above, a protrusion is provided on the bracket to serve as a swing fulcrum, but this protrusion may be provided in an annular shape at the center of the upper roll.

In addition, in each of the above embodiments, the bracket, jaw, roll, etc. are provided with an unchanging protrusion, but the protrusion is rotatable like the ball or roll in a bearing, so that it can be worn out during use. It may be possible to reduce the

In addition, in each of the above embodiments, the bracket, the
Although the protrusion is fixed to a roll or the like, in short, this protrusion must be integrated with either of the brackets and the press body so that the protrusion can be configured in an unchanging shape and the press body such as the slide or roll can be swung. It is not limited to the structure of each of the above embodiments.

〔Effect of the invention〕

A swing fulcrum is provided between a pressing body such as a jog or a roll and the bracket, and is integrally connected to either of them to swing the pressing body in a transverse direction perpendicular to the direction in which the member is fed. Since it is constructed with long protrusions, its posture relative to the members can be changed arbitrarily, and even a plurality of members arranged in parallel can be reliably clamped and fed.
