Scrap conveying device utilizing reciprocating motion of press machine

Abstract

To solve such a problem that conventional scrap conveying devices for press machines require a driving device such as a motor separately from the press machine.SOLUTION: In a scrap conveying device comprising an air cylinder, a rotary actuator, a ratchet bearing, and a belt conveyor, the air cylinder performs repeated reciprocating motion by the reciprocating linear motion of a press machine, the rotary actuator converts the reciprocating motion of the air cylinder into a rotational motion of a fixed angle, and the ratchet bearing transmits only the unidirectional rotation of the rotational motion of the rotary actuator to the belt conveyor. The problem is solved by the scrap conveying device.SELECTED DRAWING: Figure 1

[0004] Conventional scrap transport devices for press machines have the problem that they require a drive device such as a motor separate from the press machine. [Means for solving the problem]

[0005] A scrap transport device equipped with an air cylinder, a rotary actuator, a ratchet bearing, and a belt conveyor. The air cylinder undergoes repeated linear motion due to the repeated linear motion of the press machine, The rotary actuator converts the reciprocating motion of the air cylinder into a rotational motion at a certain angle, The ratchet bearing transmits the rotational motion of the rotary actuator to the belt conveyor in only one direction. The problem is solved by the scrap transport device.

[0006] In the scrap transport device described above, The rotary actuator and the ratchet bearing are connected by a sprocket and a chain or a silent chain, a toothed pulley and a toothed belt, a pulley and a belt, or a gear mechanism. The problem is solved by the scrap transport device.

[0007] In the scrap transport device described above, The rotary actuator has a rotation angle of 90°, 100°, 180°, 190°, or 270°, or is an angle-adjustable rotary actuator. The problem is solved by the scrap transport device.

[0008] In the scrap transport device described above, The present invention is characterized in that it has a reverse prevention ratchet mechanism instead of a ratchet bearing. The problem is solved by the scrap transport device. Effect of the Invention

[0009] The scrap transport device no longer requires a drive device separate from the press machine, which simplifies the scrap transport device and reduces energy consumption. [Brief description of the drawings]

[0011] Next, the present invention will be described in detail by way of examples with reference to the accompanying drawings. EXAMPLES

[0012] In FIG. 1, a scrap transport device 1 according to the invention includes an air cylinder 2, a rotary actuator 3, a ratchet bearing 4, and a belt conveyor 5.

[0013] The cylinder 6 and piston rod 7 of the air cylinder 2 are respectively engaged with a slide portion to which an upper die of a press machine (not shown) is fixed and a bolster portion to which a lower die is fixed, and as the slide portion of the press machine reciprocates, air is discharged to air tube 11 or air tube 12 via air discharge portion 9 or air discharge portion 10. Fastener 8 is a fastener that fastens the bolster portion of the press machine and the piston rod 7 of the air cylinder 2. In FIG. 1, the piston rod 7 is engaged with the bolster portion and the cylinder 6 is engaged with the slide portion, but this may be reversed.

[0014] The air tubes 11 and 12 are engaged with the air supply port of the rotary actuator 3, and air is sent to the rotary actuator 3, causing the rotary actuator to rotate at a certain angle and then rotate in the reverse direction. These rotations are then repeated.

[0015] The rotary actuator 3 has a rotation angle of 90°, 100°, 180°, 190°, or 270°, or is an angle-adjustable rotary actuator.

[0016] The ratchet bearing 4 is a bearing that transmits rotation in only one direction and does not transmit rotation in the opposite direction. The rotary actuator 3 is connected to the ratchet bearing 4 by transmission elements 13, 14, and 15, and the ratchet bearing 4 functions to transmit only one-way rotation of the rotary motion of the rotary actuator 3 to the belt conveyor 5. The transmission elements 13, 14, and 15 are, but are not limited to, a sprocket and chain or a silent chain, a toothed pulley and a toothed belt, a pulley and a belt, or a gear mechanism.

[0017] Instead of the ratchet bearing, a reverse prevention ratchet mechanism may be used. [Industrial Applicability]

[0018] The scrap transport device can be simplified and energy saving can be achieved, making it suitable for industrial use. [Explanation of symbols]
