BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing molded articles in press working, and is applied to take out molded articles and scraps from a soundproof case when a press machine is surrounded by a soundproof case to cut off noise during press working. be able to. Further, the present invention can be applied to a case where a material used in a press machine is introduced from outside the soundproof case.

[0002]

2. Description of the Related Art Conventionally, when removing molded articles and scraps from a press machine surrounded by a soundproof case, a door for an operator to enter and exit the soundproof case is provided, and the molded articles and scraps accumulated in the accumulation box are manually removed. Was. In addition, in the case of material input, the coil material is supplied through a duct penetrating the soundproof case, and a sound reduction effect of the duct was expected. Also,
Blanks or semi-finished products have been carried in through ducts or manually through doors. Also, when carrying blanks and semi-finished products or carrying out molded products and scraps on a conveyor, an opening for passing the conveyor is provided in the soundproof case, and this is left open to reduce noise or sound. Was not provided. The materials, molded products and scrap are hereinafter referred to as molded products and the like.

[0003]

Among the above-mentioned prior arts, providing a door in the soundproof case does not pose a problem in that the process from loading to unloading of a molded article or the like cannot be automated. Even if a duct is provided, only a slight attenuation of sound can be expected, and if the device is used with the opening open, even if the sound is slightly reduced, there is almost no sound insulation effect. Except for these drawbacks, the purpose of the present invention is to expect that the opening of the soundproof case cannot be expected to be closed, but by providing means that can be substantially closed, the sound insulation effect is high, and in press working that does not hinder automation of press working. An object of the present invention is to provide a molded product removal device.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, a configuration of the present invention is a device for removing a molded product in a press working provided in a soundproof case surrounding a press machine. It is characterized in that a plurality of such members are provided so as to sandwich a molded product or the like, and at least one member is provided with a member which always closes a passage and cuts off press working noise. A soundproofing plate extending in the radial direction which equally divides the circumferential angle from the shaft with the member, and a soundproofing plate continuously extending from the outer peripheral end in an arc of a required length in the direction opposite to the rotation direction of the shaft on the same circumference. And a plurality of rotary shutters. A duct provided with the other members at a required length from the opening of the soundproof panel to the outside, and an open / close shutter that opens and closes the duct in a direction perpendicular to the duct at required intervals at two places along the length of the duct. . Still another member is a set of squeeze rolls made of a soft material which presses a molded product or the like from above and below, deforms by elasticity and adheres to each other. By reducing the pressure in the soundproof case, sound transmission was reduced, and air was sucked into the shutter and rolls at a high speed from a small gap between the soundproof case and the inside.

[0005]

The rotary shutter and the opening / closing shutter carry a molded article or the like between two shutters while one of the two shutters closes a passage (opening). Since the carriage is carried out while the shutter is closed, the passage is always kept closed and the processing noise can be cut off. One set of squeeze rolls is such that when a molded product or the like is sandwiched between the rolls, the soft material deforms and passes through the passage in close contact with the molded product, so that the passage is always kept in a closed state and the processing noise is shut off. it can. Further, when the pressure in the soundproof case is reduced, the propagation of sound is reduced. In addition, since the outside air is sucked in at a high speed from the narrow gap between the shutter and the squeeze roll and the soundproof case, the leakage of the sound is slightly reduced.

At the end of the Panel of soundproof case (2) (6)
An opening (7) is provided with a shaft (7) of a required length that faces the horizontal direction perpendicular to the direction of unloading of the molded product (4), and the center angle of the shaft (7) is equally divided, in this example, the radius at a position equally divided into 4 And a plurality of arc-shaped soundproof plates (8B) extending from the tip of the soundproof plate (8A) on the same circumference in a direction opposite to the rotation direction of the shaft (7) by a required length. A rotary shutter (8) is provided. The arc-shaped soundproofing plate (8B) is made slightly longer than half the length of an arc that equally divides the circumference. The panel (6) is provided with a duct seal (9) extending along the arc of the arc-shaped soundproof plate (8B) and having a circumferential length corresponding to the arc in the direction of rotation of the shaft (7) from the panel (6). The duct seal portion (9) continuously surrounds both sides of the rotary shutter (8) on the shaft end side with a narrow gap in the range indicated by the dotted line. When the rotary shutter (8) is intermittently stopped at the position where the soundproof plate (8A) faces up and down and left and right as shown in the figure, the tip of the arc-shaped soundproof plate (8B) and the end of the conveyor (5) A flexible chute (10) for communicating Shoot from the exit of the duct seal (9) with the required downward slope
(11) is provided, and the collecting box (12) for receiving the lower end of the chute (11) is placed on the transfer conveyor (13). The molded product (4) on the conveyor (5) passes through a flexible chute (10) and is placed on a pocket (8C) formed of a soundproof plate (8A) of a rotary shutter (8) and an arc-shaped soundproof plate (8B). Rotary shutter (8)
Is rotated 90 °, the molded product (4) is in the pocket
(8C) falls onto the chute (11)
2) Enter. Arc-shaped soundproof plate for rotary shutter (8)
Since (8B) is larger than half of the equally-divided arc, any of the rotary shutters (8) can be connected to the duct seal during rotation.
Opposed to (9), the opening is closed.

In FIG. 3, a press machine shown in FIG.
1 shows the structure of a scrap removing device (16) provided in a pit (15) below a floor (14) of (1). The lower part of the duct (17) is attached to the lower part of the duct (17) in a direction perpendicular to the axis of the cylinder, above and below the cylinder (17). 1st shutter (1
8) and a second shutter (19). Pit (1

[0008]

[Effects of the Invention] As is clear from the above description, the present invention has the following effects. 1) The opening through which the molded product of the soundproof case is passed is always closed by the shutter provided with a small gap from the soundproof case, so that press working noise can be cut off and leakage to the outside can be prevented. 2) Hold the shutter vertically or horizontally between molded products
With at least one shutter closing the opening,
Since the gap between the shutter and the soundproof case has been reduced,
Leakage of processing noise from the gap can be minimized. 3) Since the inside of the soundproof case is decompressed, the propagation of sound is reduced, and the air is sucked in from the above-mentioned gap to reduce the leakage of sound.
