Description

  The present invention relates to a material supply apparatus for supplying a material such as a billet to a forging press.

  In a forging press that forges a material that extends long in one direction, such as a billet, as the processing method, a case of performing vertical punching that presses a material in a vertical orientation (the longitudinal direction is oriented in the vertical direction) In some cases, the material is pressed in a horizontal direction (an orientation in which the longitudinal direction faces the horizontal direction) to press the material. For this reason, conventionally, a material supply device that supplies a material such as a billet to a forging press is a material that has been transported from a previous process such as a heating furnace in a vertical or horizontal posture by a robot, that is, forging. The posture was set according to the processing method in the press, and the material was supplied to the material supply position of the forging press.

  However, in a device that supplies materials to a forging press with a robot, if the processing cycle of the forging press is short, the material supply operation takes longer than the processing cycle, which is a factor that hinders the improvement of forging press productivity. There was a problem of becoming.

  On the other hand, in the material supply apparatus (billet supply equipment) proposed in Patent Document 1, the billet heated in the heating furnace is conveyed by a conveyor to the upper vicinity of the material supply position of the forging press in a lateral orientation, When performing horizontal punching with a forging press, the billet stopped on the conveyor is gripped by the robot and supplied to the material supply position (on the horizontal stand) during horizontal punching. When vertical punching is performed, the conveyor The billet that is discharged from the discharge end of the pipe is placed in a vertical orientation by guiding it with a curved tubular chute, and is supplied to the material supply position (on the stand for vertical placement) during vertical placement. The billet supply operation time is reduced.

  In the material supply device of the above-mentioned Patent Document 1, a conveyor that conveys the billet from the heating furnace to the vicinity of the upper position of the material supply position of the forging press, and a chute that guides the billet from the conveyor to the material supply position at the time of vertical punching, respectively. When the forging press and the material supply device are viewed as one facility, the layout requires a space that extends long in one direction. .

  Also, when performing horizontal punching with a forging press, processing is performed with the longitudinal direction of the billet oriented in a direction perpendicular to the conveying direction, so the robot has been conveyed in a posture in which the longitudinal direction is directed to the conveying direction by the conveyor. The billet is rotated 90 degrees in a horizontal plane, and it takes time for the material posture changing operation, which may lead to a further decrease in the productivity of the forging press at the time of horizontal driving.

  Then, this invention makes it a subject to provide the material supply apparatus for forge presses which has a high freedom degree of layout including a forge press, and can supply material efficiently.

  In order to solve the above-described problems, the present invention provides a material supply device for a forging press that selectively supplies a material having a shape extending long in one direction to a forging press in a vertically or horizontally oriented posture. A conveyor which conveys the material received from the forging press to a position near the upper side of the forging press, a vertical chute for guiding the material received from the conveyor to the material supply position in a vertical posture, and the material received from the conveyor A lateral chute for guiding the material to the upper side of the material supply position in a lateral orientation, and a robot for transferring the material guided to the upper side of the material supply position by the lateral chute to the material supply position. The conveyor, the vertical chute and the horizontal chute intersect each other in the horizontal plane with the material conveying direction in the forging press. Are arranged in a state extending toward the longitudinal beating chute and horizontal beating chute adopts the configuration that is connectable to selectively conveyor.

  In other words, by arranging the conveyor and each chute of the material supply device in a state extending in the direction intersecting the material conveyance direction in the forging press in the horizontal plane, the freedom of layout combining the material supply device and the forging press is achieved. In addition, the time required for material supply can be shortened by eliminating the need to change the posture of the material with a robot when performing horizontal punching with a forging press.

  Here, the vertical hitting chute can be moved horizontally, and the horizontal hitting chute can be rotated about a position away from the connection position with the conveyor in the vertical plane. For example, when switching between vertical punching and horizontal punching in a forging press, the connection of the vertical hitting chute and the horizontal hitting chute in the material supply device to the conveyor can be smoothly performed.

  As described above, the forge press material supply device of the present invention is a conveyor that conveys material to the vicinity of the upper portion of the material supply position of the forge press, and a vertical chute that can be selectively connected to the conveyor. And the horizontal chute are arranged so as to extend in a direction that intersects the conveying direction of the material in the forging press and in the horizontal plane, respectively, so that the flexibility of layout combining the material supply device and the forging press is increased. In addition, it is possible to improve the productivity of the forging press by shortening the time required for material supply when performing the horizontal punching with the forging press.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. This material supply apparatus supplies a material having a shape extending in one direction such as a billet to a forging press. As shown in FIGS. 1 and 2, the forging press main body 1 and a transfer constituting a part of the forging press. A conveyor 3 that is installed above the material supply side (left side of the drawing) of the apparatus 2 and conveys the material to the vicinity of the upper position of the material supply position of the transfer apparatus 2, and a vertical connection that can be selectively connected to the conveyor 3 A hitting chute 4 and a horizontal hitting chute 5 and a robot 6 for transferring material from the horizontal hitting chute 5 to the material supply position of the transfer device 2 are provided. And the conveyor 3, the vertical chute 4 and the horizontal chute 5 are each arranged in a state extending in a direction orthogonal to the conveying direction of the material in the forging press in the horizontal plane.

  1 and 2 (excluding the part of the horizontal shooting chute drawn with a one-dot chain line) show the state when vertical punching is performed with a forging press. FIG. 4 and FIG.

  The forging press main body 1 is driven by a servo motor (not shown), and can simultaneously process a plurality of materials arranged in the material conveying direction.

  The transfer device 2 includes a pair of clamp members 7 that sandwich the material from the left and right (the direction perpendicular to the material conveyance direction in the forging press in the horizontal plane). By moving in the left-right direction, the material supplied by the material supply device is sent to the forging press main body 1 and the material processed by the forging press main body 1 is unloaded from the forging press main body 1. FIGS. 1 and 2 show a state in which both clamp members 7 are at the forward limit in the material conveying direction, the lower limit in the vertical direction, and the open limit in the left and right direction.

  The conveyor 3 conveys the material heated in a heating furnace (not shown) to a position near the upper side of the material supply position of the transfer device 2 in a lateral orientation in which the longitudinal direction is directed to the conveying direction. Is extended in the horizontal direction, but is inclined slightly downward at the discharge end so that the material can be smoothly fed from the discharge end to the vertical shooting chute 4 or the horizontal shooting chute 5.

  As shown in FIG. 3, the vertical chute 4 is formed in a cage shape and a curved tubular shape, and when vertical punching is performed by a forging press, the transfer device is configured such that the material received from the conveyor 3 is in a vertical orientation. 2 to the material supply position. And it is possible to move horizontally in the material transport direction in the forging press, and when switching the processing method in the forging press from vertical strike to horizontal strike, it is opposite to the forge press main body 1 from the state of FIGS. It moves horizontally in the direction (left side in FIG. 1) and retreats to a position where it does not interfere with the side-shooting chute 5 and the robot 6.

  The lateral chute 5 supplies the material received from the conveyor 3 in the lateral orientation when the lateral strike is performed by a forging press as shown in the dashed line in FIG. 2 and FIG. It guides to the upper part of the position, and is supported by supporting members 8 at a plurality of positions in the longitudinal direction. A stopper 5a for stopping the material is provided at the tip, and a notch 5b for the robot 6 to grip the stopped material is formed in the vicinity of the tip of the side wall as described later. Although illustration is omitted, the support member 8 is centered on a position away from the connection position with the conveyor 3 in the vertical plane when the rod of the air cylinder connected to the central portion in the longitudinal direction of the support member 8 expands and contracts. When the processing method in the forging press is switched from the horizontal strike to the vertical strike, it is turned downward from the state of FIG. 4 so that it does not interfere with the vertical strike chute 4. evacuate.

  As described above, when the vertical hitting chute 4 is horizontally movable and the horizontal hitting chute 5 is rotatable in the vertical plane, when switching between vertical hitting and horizontal hitting in the forging press, It is possible to smoothly switch the connection between the vertical chute 4 and the horizontal chute 5 to the conveyor 3.

  The robot 6 is installed at a position where the base portion 6a is higher than the discharge end of the conveyor 3, and holds the arm 6b (see FIG. 5) at a position higher than a predetermined position when performing vertical driving with a forging press. Thus, it does not interfere with the vertical shooting chute 4.

  FIG. 5 shows a state in which a horizontal punching is performed with a forging press. At this time, as described above, the vertical hitting chute 4 is horizontally moved to a position where it does not interfere with the horizontal hitting chute 5 and the robot 6 (not shown), and the robot 6 extends the arm 6b from the horizontal hitting chute 5. The taken out material is placed at the material supply position of the transfer device 2.

  This material supply device is configured as described above, and the conveyor 3 and the chutes 4 and 5 are arranged in a state extending in a direction perpendicular to the material conveying direction in the forging press. Compared to the conventional one arranged in parallel with the material conveying direction, the layout of the equipment combined with the forging press is more flexible and the length of the installation space can be shortened.

  In addition, when performing horizontal punching with a forging press, it is not necessary for the robot 6 to rotate the material in a horizontal plane, so that the material can be supplied in a shorter time than the above-described conventional one. As a result, in a forging press, productivity can be improved, and a decrease in material temperature before processing is suppressed, and the load during processing is reduced. You can do it.

  In addition, the conveyor and each chute change the direction in the horizontal plane according to the positional relationship of the forging press and the equipment of the previous process such as a heating furnace, and in a direction intersecting the material conveying direction of the forging press at a predetermined angle. It can also be arranged in an extended state. However, if the orientation of the side-shooting chute is changed, it is necessary to rotate the material in the horizontal plane by the robot. Therefore, at least for the horizontal-shooting chute, in the material conveying direction of the forging press and in the horizontal plane as in the embodiment. It is desirable to arrange them orthogonally.
