The paper table 201 is further rotated in a tilted state. Upper fork claws 203a, 203a and lower fork claws 203b, 203b are slidably supported by the paper mounting table 201, and the upper fork claws 203a, 203a and the lower fork claws 203b, 203b are hydraulic cylinders (not shown). (Shown) to hold a large number of papers P based on the relative movement. In the width direction of the paper P (the direction of arrow G in the figure), a guide rail portion 205 extends from the paper mounting table 201, and the guide rail portion 205 is mounted on the paper mounting table 201. A regulating device 206 for regulating the edge position of the paper P is slidably supported and can be moved according to the size of the paper. This regulation device 2
Reference numeral 06 has a rail portion 206a extending in the thickness direction of the paper, and the rail portion 206a supports the distal end opening portion 207a of the flexible duct 207 movably. A driving device (not shown) is provided inside the regulating device 206, and is configured to move along the thickness direction of the paper through the front end opening 207a. On the other hand, the flexible duct 207 is connected to a blower device (not shown), and blows air from a distal end opening 207a.

Now, as shown in FIG. 1, a large number of papers P are sandwiched between the paper mounting tables 201, and the paper mounting tables 201 are tilted in the direction of arrow D by a predetermined angle. Then, in the tilted state, the paper placing table 201 is rotated by 90 degrees so that the regulating device 206 is located on the lower side. In this state, the distal end opening 20 of the flexible duct 207 disposed in the regulating device 206 is

After a little driving of 03b and 203b to weaken the pinching force on the paper P, a blower device (not shown) is driven. The air from the blower device is blown out from the leading end opening 207a to the edge of the paper P via the flexible duct 207.
With the air being blown out in this manner, the tip opening 20
When the sheet 7a is moved along the rail portion 206a, air is blown over the entire edge of the placed paper,
Paper alignment is performed.

[0006]

According to the above-mentioned prior art, the paper loading table 201 and the like which are rotated with respect to the apparatus main body 202 have the tip opening 20 to which air is supplied.
7a and a hydraulic cylinder to which oil is supplied are arranged, and are connected to a pump device or a blower device attached to the device main body 202 by a flexible hose or duct 207. Therefore, when the paper mounting table 201 is rotated with respect to the apparatus main body 202, there is a risk that these hoses or the like may interfere, or the hose or the like may be forcibly bent and damaged.

Further, when pulsation occurs in the blower device, the amount of air blown out from the opening 207a at the end of the flexible duct 207 fluctuates, and there is a possibility that work such as paper alignment cannot be performed properly.

Accordingly, an object of the present invention is to provide a paper processing machine capable of smoothly rotating a paper mounting table and supplying air without pulsation.

, The tilt base 10 including the rotation support shaft 11 and the like is tilted and lifted. Therefore, the paper mounting table 100 rotatably supported by the rotation support shaft 11 is also tilted.

Next, the tilted paper table 100 is manually rotated to a 90-degree rotation position with the regulating plate 151 down, and fixed at that position using the stopper 150.
In this rotation position, the hydraulic paths 11a, 11b, 1
1c and the hydraulic paths 102a, 102b, 102c communicate with each other, so that the fork claws 108, 108 can be moved, and the holding force on the paper is reduced by a predetermined switch operation.

On the other hand, the housings 111 and 11 of the paper
1 and the air tank T are communicated by the two air supply paths E, E, regardless of the rotational position or the tilting position of the paper placing table 100. The air tank T and the blower device 3 are similarly connected via a flexible duct 119. Therefore, when the operator activates the blower device 3, the air from the blower device 3 is supplied to the inside of both the housings 111 via the air tank T.

Openings 112a, 112a are formed in the housings 111, 111 on the paper placement side, and belts 121 are provided inside the openings 112a, 112a.
(Especially, the closing part 121a) is stretched. Therefore, when air is supplied to the inside of the casings 111, 111 as described above, the belt 121 is opened by the air pressure.
It will bend to 12a and 112a side. By the way, the width d ₁ of the belt 121 is wider than the opening width of the openings 112 a, 112 a, and the belt 121 is
b, the belt 1
21 are urged toward the inside of the edges (recesses 112b, 112b) of the openings 112a, 112a, and as a result,
The openings 112a, 112a are closed.

However, in the portion of the nozzle device 130, the belt 121 is stretched by the roller 137 so as to be separated from the opening 112a to form an air blowing portion 121b. The width d _{1 of the} belt 121 is
Since 2,112 is less than the width d ₂ of the space formed,
The air inside the housings 111, 111 passes between the edge in the width direction of the belt 121 and the inner wall of the member 112, and is blown out from the opening 139a as shown by an arrow H in FIG. Accordingly, air is blown to the edge (not shown) of the paper, and the air is blown between the plurality of papers placed.

At this time, the motor 126 attached to the base member 105 has been activated, and its driving force is transmitted to the respective drive sprockets 123 via the chain 127 and the drive transmission shaft 124. As a result, A chain 125 stretched between the sprockets 122 is driven to rotate. Since the nozzle device 130 is locked to the chain 125, the nozzle device 13
0 moves in the thickness direction of the placed paper. Therefore,
The air blowing unit 121b is also moved, and air is sequentially blown between the placed papers as the paper moves. As a result, the paper into which the air is blown moves until the lower edge of the paper hits the regulating plate 151, and the paper is aligned.

When the paper alignment is completed in this way, the fork claws 108, 108 are activated again to re-clamp the paper, and
The paper mounting table 100 is rotated to the original rotation position (0-degree position). The hydraulic cylinder 9 is reset at the rotation position, and the paper placing table 100 is erected. Thus, the paper alignment work is completed.

Although the operation during the paper aligning operation has been described here, the same operation is performed by appropriately changing the rotation position and the tilting angle of the paper mounting table 100, so that the paper handling,
Other operations, such as inversion, can also be performed.

Thus, the housing 111 for supplying air to the nozzle device 130 (air blowing portion 121b) is fixed, and does not move in the thickness direction of the paper unlike the flexible duct of the prior art. Therefore, no space is required for movement. In addition, the nozzle device 1
The motor 30 for moving the nozzle device 130 and the nozzle device 13
Both the housings 111 that movably support 0 may be small. Therefore, the air blowing device 118 can be made compact.

Further, since the air blowing device 118 is compact, it can be stored in the paper mounting table 100. Therefore, the air blowing device 1 is different from the prior art.
18 does not need to be provided on the regulating plate 151,
Lightening of itself can be achieved. Further, since the regulating plate 151 is light, the rail member 152 that supports the regulating plate 151 can be simple, and the entire apparatus can be made compact. Further, since the regulating plate 151 is light, the operation of moving the regulating plate 151 becomes easy.

On the other hand, since the driven nozzle device 130 is housed in the housing 111, the operator does not accidentally pinch his hand.

Further, a rotating paper mounting table 100,
Air supply between the tilt base 10 that is only rotated and not rotated is performed via an air tank T formed by the paper mounting table 100 and the tilt base 10. The air tank T has an annular shape, and the housing 1 of the air blowing device 118
11 is communicated with the air supply path E which always opens to the air tank T irrespective of the rotation position of the paper mounting table 100. Therefore, air can always be supplied regardless of the rotation position of the paper table 100. In this case, unlike the related art, a flexible duct is not used between the rotating side (the paper mounting table 100 side in the present embodiment) and the non-rotating side (the tilt base 10 side in the present embodiment). Table 10
When rotating 0, the duct does not get in the way. Further, there is no possibility that the flexible duct is damaged.

Further, hydraulic paths 11a, 11b, 11c communicating with the pump device 5 arranged in the apparatus main body 2 are formed in the rotary support shaft 11, and hydraulic paths 102a, 102b, 102c communicating with the hydraulic cylinder 109 are formed. The hydraulic paths 11a, 1
1b, 11c and hydraulic paths 102a, 102b, 102c
Are configured to communicate with each other at a predetermined rotation position of the paper mounting table 100, so that oil can be supplied to the hydraulic cylinder 109 between the rotating side and the non-rotating side without using a flexible hose. Therefore, the flexible hose does not hinder the rotation of the paper table 100. Also, there is no need to worry about breakage of the hose.

On the other hand, the housing 11 via the air tank T
1 is supplied with air, so that pulsation on the side of the blower device 3 can be eliminated. Therefore, work such as paper alignment can be appropriately performed. Also, one blower device 3
Is supplied to the two housings 111, 111 by the air tank T and is supplied through the two air supply paths E, E. Therefore, even if the airflow resistance is slightly different, the air is supplied to both air supply paths E, E, and the air is properly blown out.

In the above-described embodiment, the paper mounting table 100 is manually rotated. However, the present invention is not limited to this, and the paper mounting table 100 may be rotated by a driving force from a driving source such as a hydraulic pump. Is also good.
