Description

[Detailed Description of the Invention] The present invention relates to an apparatus for charging sheet molding compound material (hereinafter abbreviated as SMC material) into a mold.

One type of device for charging SMC material into a mold is a device that has an arrowhead-shaped portion at the tip to pierce and hold the SMC material, and then inserts it into the mold when the mold is open. In this type of feeding device,
SMC being impaled and held by a stabbing rod
removing the material from the piercing rod by pushing it toward the tip of the piercing rod with a scraping member;
It will be dropped onto the lower mold. Since the piercing rod is positioned in advance with respect to this lower mold, the fallen SMC material will be placed on the lower mold at a predetermined position. However, in conventional feeding devices of this type, the mold surface of the lower mold is tilted. In the case where the SMC material fell onto a predetermined position, it would slide along the mold surface and be displaced from the predetermined position.

The purpose of the present invention is to provide an SMC material charging device that can accurately position and charge SMC material even when the mold surface of the lower mold is inclined.

In order to achieve this purpose, the present invention
The SMC material charging device includes (a) a main body of the charging device; (b) a stabbing rod extending downward from the main body and having an arrowhead-shaped portion at a lower end to pierce and hold sheet molding compound material; c) a discharging member provided to be movable relative to the stabbing bar in a direction parallel to the stabbing bar; and (d) an actuating member that operates relative to the stabbing bar in a direction parallel to the stabbing bar; a scraping member drive device that moves the scraping member between a scraping position protruding below the tip of the stabbing rod and a standby position retracted from the tip position; and (e) between the scraping member and the actuating member. (f) a stopper defining a relative lowering limit of the brushing member with respect to the actuating member;

In the charging device configured in this way, the driving force of the scraping member drive device is applied to the scraping member via the spring, so that the scraping member is not allowed to move after it comes into contact with the SMC material pierced by the stabbing rod. Advancement is blocked by SMC material,
The actuating member moves forward while compressing the spring. Then, when the amount of compression of the spring increases and its elastic force overcomes the SMC material holding force of the stabbing rod, the SMC material comes off from the stabbing rod and falls onto the lower mold, but at this time, the scraping member is also attached to the spring. This is followed by the elastic force, and the SMC material is pressed against the mold surface of the lower mold. Therefore, even if the mold surface is inclined, the SMC material is prevented from sliding on the mold surface, and the SMC material can be accurately placed at a predetermined position on the lower mold.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 schematically shows the SMC material charging device according to the present invention, and this charging device has a mold surface 10.
This is for charging the SMC material 14 into the lower mold 12 which is inclined. The feeding device is the device main body 16
The main body 16 can be moved by appropriate means between a material input position directly above the lower mold 12 and a material receiving position removed from the lower mold 12. The means are the same as before,
Moreover, since it has no direct relation to the present invention, illustration and description will be omitted.

A piercing rod 18 extends from the device body 16, and an arrowhead-shaped portion 20 is provided at the lower end of the piercing rod 18. The arrowhead-shaped portion 20 is the piercing rod 18
It is slightly thicker than the rest of the body, and has a pointed tip. The piercing rod 18 is attached to the device main body 1
6 are provided with a plurality of them at appropriate intervals, and their tips, that is, their lower ends are connected to the main body 1 of the device.
6 is brought directly above the lower mold 12, the lower mold 1
The two mold surfaces 10 have a length such that they are spaced from each other by the same small distance.

A scraping plate 22 is provided movably along the stabbing rod 18. This scraping plate 22 is provided with a plurality of through holes 24, and the piercing rod 18 is provided to pass through the through holes 24. This scraping plate 22 is fixed to the lower end of the piston rod 28 of a plurality of air cylinders 26 that are attached downward to the device main body 16, and the piercing rod 1 is
It is designed so that it can be moved in a direction parallel to 8. That is, in this embodiment, the air cylinder 26 serves as a blow-off member driving device, and the piston rod 28 serves as an operating member.

A single or a plurality of scraping pins 30 are attached to the scraping plate 22 in parallel with the piercing rod 18. In other words, the removal plate 22
A cylindrical guide member 32 is fixed to the
The guide member 32 is slidably inserted into the through holes 34 and 36 of the scraping plate 22. The scraping pin 30 has flanges 38 and 40 near its lower end and at its upper end, respectively, and a compression coil spring 42 is installed between the flange 38 and the scraping plate 22. The spring 42 urges the knock-off pin 30 downward, that is, toward the tip of the stabbing rod 18, but the limit of movement of the knock-off pin 30 in this direction is until the flange 40 seats on the upper end surface of the guide member 32. It has come to be defined by

The set load of the spring 42 is applied to the flange 4.
0 is seated on the guide member 32, the SMC material holding force is smaller than the SMC material holding force of the piercing rod 18, but the spring constant is selected so that when compressed by a certain amount, the biasing force becomes larger than the holding force. There is.

The inputting device configured as described above receives SMC material at the SMC material receiving position. That is, by lowering the device main body 16 or raising the support plate supporting the SMC material, the SMCs placed on the support plate can be removed.
The arrowhead-shaped portion 20 of the stabbing rod 18 is pierced into the material. Thereafter, the stabbing rod 18 and the support plate are vertically separated, but since the arrowhead-shaped portion 20 of the stabbing rod 18 is made slightly thicker than the other parts of the stabbing rod 18 as described above, the SMC material 18 Once penetrated, it will not come out unless a certain force is applied, and this force is
The SMC material 14 is large enough to hold the SMC material 14 relative to its weight;
The material 14 is now held by the piercing rod 18. In this state, the piston rod 28 of the air cylinder 26 is retracted, and the knock-off pin 30 is in a standby position away from the SMC material 14.

Subsequently, the device main body 16 is moved to the charging device to convey the SMC material 14 to a predetermined position on the lower mold 12. FIG. 1 shows this state.

At this time, the air cylinder 26 is operated to lower the wipe-off plate 22. As a result, the scraping pin 30 attached to the scraping plate 22 also descends and comes into contact with the upper surface of the SMC material 14. Since the set load of the spring 42 that urges the scraping pin 30 downward is smaller than the SMC material holding force of the stabbing rod 18 as described above, the scraping pin 30 is
It stops at the position where it touches the material 14, and the spring 4
2 is compressed. When the amount of compression of this spring 42 becomes greater than the sum of the amount of protrusion of the arrowhead-shaped portion 20 from the SMC material 14 and the thickness of the SMC material 14, the biasing force of the spring 42 increases the SMC material holding force of the piercing rod 18. becomes larger, and the sweep-off pin 30 moves to the sweep-off position.
Push the SMC material 14 off the piercing rod 18.
The SMC material 14 that has been pushed out is placed on the mold surface 1 of the lower mold 12.
0, but at this time the knock-off pin 30
is the SMC material 1 due to the biasing force of the spring 42.
4 and presses it against the mold surface 10. Therefore, the SMC material 14 is prevented from sliding on the mold surface 10 even though the mold surface 10 is inclined, and is placed into the lower mold 12 in an accurately positioned state. and,
After the entire SMC material 14 is fully adhered to the mold surface 10, the air cylinder 26 is used to remove the SMC material 14 from the plate 22.
When the SMC material 14 is raised and the knock-off pin 30 is moved away from the SMC material 14, the SMC material 14 no longer slides across the mold surface 10. Therefore, when the charging device is retracted from the charging position and the upper mold is lowered, the SMC material 14 is compressed while being accurately positioned in the lower mold 12, and can be molded into a predetermined shape.

FIG. 3 shows another embodiment of the present invention. In this embodiment, a pressing member 52 is rotatably attached to the lower end of the sweep-off pin 30 by a pin 50, and the pressing member 52 is in close contact with the SMC material 14 on a relatively wide surface along the inclined surface. Therefore, it has the advantage that it can be pressed against the mold surface 10 with a sufficiently strong force without fear of causing a dent in the SMC material 14. Since the other parts are the same as those in the previous embodiment, the same reference numerals are simply given to the corresponding parts.

Incidentally, instead of fixing the scraping member such as the scraping pin 30 to the scraping plate 22, the piston rod 28 of the air cylinder 26 is slidably inserted into the scraping plate 22.
It is also possible to arrange a compression coil spring between 8 and the wipe-off plate 22 to have the same effect as the spring 42 in the above two embodiments, and in this case, the wipe-off member is Even when a plurality of such members are provided, the SMC material 14 can be pressed against the mold surface 10 all at once.

In addition, it goes without saying that the present invention can be implemented in various modifications and improvements based on the knowledge of those skilled in the art without departing from the scope of the claims for utility model registration.
