Abstract

PURPOSE:To provide an air suction/discharge system generating only weak noises for the sucker of a sheet suction/conveyance mechanism. CONSTITUTION:An air suction/discharge mechanism 5 is constituted of an air cylinder 51, a gear train 52 reciprocating its piston rod 51a, and a drive motor 53 for it. The piston rod 51a is reciprocated by the drive motor 53 at a proper low speed, the air suction/discharge mechanism 5 generates a weak vibration sound, the negative-pressure or positive-pressure air A generated by the air cylinder 51 is fed to a sucker 15 to suck or release a sheet 3 respectively. A room can be kept quiet with no noises when a sheet suction/conveyance mechanism 1 is installed in the room such as an office.

Slide rail 11 provided between the stackers 4A and 4B
And a mover 12 that moves along the mover 12, a lift mechanism 13 fixed to the mover 12, and a rod fixed to the lift mechanism 13.
It consists of a suction cup 15 attached to the tip of 14. In order to exhaust the air A from the suction cup 15, an air compressor (COM
An exhaust mechanism 2 including a P) 21 and a control valve 22 is provided. It is assumed that the air compressor 21 is always operating and the sheet 3 to be conveyed is contained in the stacker 4A. When the sheet 3 is conveyed, the mover 12 is stopped at the position of the stacker 4A, and the lifting mechanism 13 lowers the suction cup 15 to contact the sheet 3. When the control valve 22 is opened here, the air A is exhausted from the suction cup 15 and the seat 3 is adsorbed. Then raise the suction cup 15,
When the stacker 4B moves to the position of the stacker 4B and descends, the control valve 22 is closed and the exhaust is stopped, the sheet 3 is released from the suction cup 15 and accommodated in the stacker 4B.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Since the moving element 12 and the lifting mechanism 13 are driven by respective motors, noise is hardly generated. On the other hand, the exhaust mechanism 2
Makes a lot of noise. That is, it is general that the air compressor 21 is always operated as described above, and the exhaust is performed by the control of the control valve 22. The normal air compressor 21 has a considerable vibration noise, and when the suction transport mechanism 1 is installed in a room such as an office, it constantly gives noise to the room, which is very troublesome. On the other hand, it is desirable to use an exhaust system that does not generate noise or emits noise only to the extent that it does not interfere. An object of the present invention is to provide an air intake / exhaust system that generates only a weak noise in order to install the sheet suction / conveyance mechanism 1 in a room such as an office.

SUMMARY OF THE INVENTION The present invention is an air suction / exhaust system for a sheet suction mechanism that achieves the above object.
An intake / exhaust mechanism including an air cylinder, a gear train that reciprocates a piston rod of the air cylinder, and a drive motor for the gear train is provided for the suction cup. The drive motor reciprocates the piston rod at an appropriate low speed to reduce the vibration noise generated by the intake / exhaust mechanism, and supply the negative pressure or positive pressure air generated by the air cylinder to the suction cup to suck or suck the sheet. It releases each.

The operation of the above-described sheet suction / conveyance mechanism 1 will be described. The mover 12 is stopped at the position of the stacker 4A, and the lifting mechanism 13 lowers the suction cup 15 to bring it into contact with the sheet 3.
Next, when the drive motor 53 of the intake / exhaust mechanism 5 is rotated at an appropriate low speed, the gear train 52 causes the piston rod 51a to move.
Moves slowly in the direction of arrow C 1 . Due to this movement, the negative pressure generated inside the air cylinder 51 is applied to the suction cup 15, the air A is exhausted, and the seat 3 is adsorbed. The sucked sucker 15 is moved up and down by the movement of the lifting mechanism 13 and the mover 12, stopped at the position of the stacker 4B, and further lowered. Here, when the drive motor 53 is also reversely rotated at a low speed and the piston rod 51a is slowly moved in the direction of the arrow C 2 , a positive pressure is generated inside the air cylinder 51, which is given to the suction cup 15 to release the suction. Then, the sheet 3 is stored in the stacker 4B. In the above, the rotation of the drive motor 53 and the movement of the piston rod 51a are slow and slow,
Further, since the operation is performed only when the sheet 3 is sucked and released, the vibration noise generated by the intake / exhaust mechanism 5 is extremely weak and intermittent as compared with the conventional exhaust mechanism 2, and the sheet suction / transport mechanism 1
The room, such as an office, where is installed will be quiet and quiet. In addition, in this case, since the intake / exhaust mechanism 5 operates at a low speed in this case, it may not be suitable when high-speed conveyance is required.
