Description of the Related Art Heretofore, as a compact device for releasing adhesion between sheets of paper that have been polymerized in a large amount or for drying printing ink, for example, one disclosed in Japanese Utility Model Publication No. 62-40998 is known. ing. This device holds the sheet stack on the two slopes of the receiving frame that are orthogonal to each other with the corners of the sheet stack facing down, and vibrates the receiving frame with a vibrating device.
Further, the air ejector is reciprocally moved so that air is blown between the sheets along the ventilation port provided at the bottom of the receiving frame, and the sheet stack is not misaligned and the sheets are not aligned. While aligning the aggregate along the slope of the frame,
Air is blown into each sheet to quickly separate the sheet stack.

[0003]

In the above-mentioned conventional paper sheet separating apparatus, the paper sheet aggregate is held in a separate container or the like and brought to this apparatus, and is moved from the container into the receiving frame for use. In addition, it is inconvenient to handle the paper sheet stack. In addition, the structure of the air injector is relatively complicated, the number of parts is large, and the device is large and heavy. Therefore, according to the present invention, a part of the apparatus can be used for transporting the sheet stack and can be mounted on the apparatus as it is. Further, the structure of the air injection unit is relatively simple, the number of parts is small, and the size and weight are small. An object of the present invention is to provide a paper sheet separating and drying device.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a case 4 having a holding portion 6 for holding the receiving frame 3 on the upper portion and a corner portion of the sheet stack P are held. Has two slopes 3c and 3d which are orthogonal to each other, and has a ventilation port 3f formed on one of the slopes so as to extend in the thickness direction of the sheet stack P, and The receiving frame 3 that is attachable to and detachable from the holding unit 6 with the corners of the sheet stack P facing downward, and the jetting position reciprocate along the extension direction of the ventilation port 3f of the receiving frame 3 to stack the sheets. The case 4 is formed so that air is blown into each sheet of the body P through the ventilation port 5a.
A sheet-feeding / drying device is configured by including a motor-driven air injection member 5 provided therein.

Is a box-like shape whose corners fit into the recesses 6 of the main body 2, and two orthogonal surfaces are open.
Can be stored. Receiving frame 3
Includes a frame body 3a and a pressing plate 3b. The frame body 3a is composed of two slopes 3c and 3d that are orthogonal to each other and a side face 3e that connects these slopes 3c and 3d.
The sheet stack P can be held on the slopes 3c and 3d with the corners facing down. A ventilation port 3f is formed on the inclined surface 3d at a position corresponding to the ventilation opening 6c in a state of being attached to the main body 2. The pressing plate 3b faces the side surface 3e and is provided so as to be movable in parallel so that the distance between the pressing plate 3b and the side surface 3e can be adjusted. 3g is a tightening mechanism for fixing or releasing the pressing plate 3b to the frame body 3a.

An air injection member 5 is swingably provided in the case 4. The air injection member 5 sucks air from the lower side by the rotation of the motor and injects the air from the upper injection port 5a. The air injection member 5 is directed toward the ventilation opening 6c and the bottom plate of the case 4 via the bracket 7. It is supported on 4b. That is, the air injection member 5 is
It is pivotally attached to the bracket 7 by a horizontal shaft 8 and can swing the upper part around the shaft 8. A guide member 5b extending in the vertical direction is provided on one side surface of the air ejecting member 5. The guide member 5b has a U-shaped cross section and a vertical guide groove. A swinging motor 9 is fixed to the upper part of one bracket 7 with the rotary shaft 9a penetrating horizontally. The rotating shaft 9a has a circular cam 10 at an eccentric position.
Is fixed. The cam 10 is fitted in the guide groove of the guide member 5b. Therefore, when the cam 10 is eccentrically rotated by the motor 9, the cam 10 reciprocates vertically in the guide groove of the guide member 5b,
The air injection member 5 is reciprocally rocked about the shaft 8. The air ejection member 5 swings while moving along the ventilation opening 6c through the ejection port 5a.

In the paper sheet separating / drying apparatus 1 of this embodiment, the receiving frame 3 is separated from the main body 2 and brought to the vicinity of the printing machine, and an appropriate amount of paper sheets are collected on the receiving frame 3 immediately after completion of printing. The body P is accommodated, the position of the pressing plate 3b is adjusted according to the thickness, and the sheet stack P is held with a margin. When the receiving frame 3 accommodating the paper sheet stack P is fitted into the recess 6 of the main body 2 and the apparatus is started, the air ejecting member 5 causes the ejection port 5 to exit.
a, the opening 6c, and the ventilation port 3f to blow air into the sheet stack P
At the same time, the motor 9 rotates to reciprocally swing about the shaft 8 while moving the jet port 5a along the ventilation opening 6c (in the thickness direction of the sheet stack P) by the rotation of the motor 9.
By this air jet, air is sequentially blown between the paper sheets, and the paper sheets are separated, and the entire sheet stack P is aligned with its corners downward, and at the same time, the drying of the printing ink is promoted.

[0010]

As described above, according to the present invention, the sheet separating / drying apparatus 1 is configured by including the case 4, the receiving frame 3, and the air jetting member 5. A holding portion 6 for holding the receiving frame 3 is provided on the upper portion of the case 4, and the receiving frame 3 is
The sheet stack P can be attached to and detached from the holder 6 of the case 4 with the corners of the sheet stack P facing downward. The receiving frame 3 has two slopes 3c, 3 that are orthogonal to each other for holding the corners of the sheet stack P.
d is provided, and a ventilation port 3f is formed on any of the slopes so as to extend in the thickness direction of the sheet stack P. Air injection member 5
Is swingably provided in the case 4, and the ventilation port 3 of the receiving frame 3 is provided.
The ejection position was reciprocally moved along f so that the air was blown into between the paper sheets of the paper sheet stack P.
