As an embodiment of the invention described in claim 2, an air cylinder is used as the paper press plate 2 b and the push-up device 2 a for lifting the paper press plate 2 in the invention described in claim 1, and as a paper press plate positioning device. An embodiment in which a lock mechanism (not shown) is attached to the air cylinder is proposed. The lock mechanism is a mechanism for fixing the position of the paper pressing plate 2b by positioning the rod of the cylinder.
Also, as another push-up device and positioning device, the press-up plate is pushed up with a spring and fixed by pushing the press-up plate with a positioning cylinder, or the press-up plate is pushed up with a hydraulic cylinder and the valve is closed to any position It is also possible to use a structure in which the paper board is pushed up by attaching a spring with a sensor to the tip of an electric cylinder or jack, and a method of stopping at an arbitrary position.
In the above, the spring with the sensor is attached because the electric cylinder or jack is stopped when the sensor detects that the spring is deflected by a predetermined amount, and the reaction force by the spring is applied after the stop to position the top surface 1b of the sheet stack. Is to keep constant.
In addition, the paper stopper 3 has a structure in which a paper stopper plate 3b is supported by a frame 3c and is lifted and lowered by a lifting device 3a. As the lifting device 3a, an air cylinder, a hydraulic cylinder, an electric cylinder, a jack, or the like can be considered.

[0007]
According to a third aspect of the present invention, the paper discharge unit according to the second aspect is a roller paper discharge unit. An embodiment of the present invention will be described with reference to FIGS. The roller discharge unit 4 is composed of a pressing roller unit 5, a driving roller unit 6, and a backup unit 7.
The pressing roller unit 5 includes a shaft 5c, a pressing roller 5a fixed to the shaft 5c, and a chain wheel 5b. The shaft 5c is rotatably held by an arm 6f. The chain wheel 5b is connected to the chain wheel 6b of the drive roller unit 6 by a chain 6g.
The outer peripheral surface of the pressing roller 5a has a high friction coefficient. As the outer peripheral surface higher than the friction coefficient of the sheet, the force that the pressing roller 5a tries to feed the sheet as a frictional force is set to be larger than the force of the frictional resistance acting between the sheets.
The driving roller unit 6 is rotatably supported by a support column 6d, and is rotatably supported by a shaft 6c that is rotationally driven by a motor 6e, a driving roller 6a fixed to the shaft 6c, a chain wheel 6b, and a shaft 6c. It comprises an arm 6f.
The backup unit 7 includes a base 7d supported by a spring 7e, a shaft 7c rotatably held by a bearing 7b attached to the base 7d, and a backup roller 7a attached to the shaft 7c.
When the pressing roller 5 of the roller discharge unit 4 is placed on the upper surface 1b of the sheet stack, and the sheet is discharged, the motor 6e is rotated to rotate the shaft 6c and the drive roller 6a and the chain wheel. 6b rotates.
The rotational force of the chain wheel 6b rotationally drives the chain wheel 5b through the chain 6g, and the shaft 5c and the pressing roller 5a rotate together with the chain wheel 5b. Since the pressing roller 5a presses the upper surface of the sheet stack 1 by its own weight, a frictional force works, and the uppermost sheet is sent out with the rotation of the pressing roller 5a.
Since the backup roller 7a is pressed against the drive roller 6a by the force of the spring 7e, it rotates as the drive roller 6a rotates. The leading edge of the sheet is sandwiched between the driving roller 6a and the backup roller 7a and is discharged to the collecting unit 15 so as to be further pulled.
In the present embodiment, discarding is performed within a range where the high-viscosity fluid does not adhere to the stationary paper plate 3b and the pressing roller 5a. This is because if a high-viscosity fluid adheres to the paper stop plate 3b or the pressing roller 5a, the paper cannot be discharged.
In the above-described embodiment, the pressing roller is attached to the swingable arm 6f. However, the pressing roller can be attached to be movable up and down. Further, if the pressing roller is pushed by a spring or the like, the force for feeding out the paper can be increased.
Also, instead of using the drive roller unit and the backup unit to discharge the paper to the collecting unit, the chute is attached so that the paper slides down, or nothing is attached and the paper is collected by natural fall without any attachment. There is also a method of discharging to the part, and it does not stick to the above-described embodiment.

According to a fourth aspect of the present invention, the paper discharge unit according to the second aspect of the present invention is a clipper discharge unit. An embodiment of the present invention will be described with reference to FIGS. 3, 4, and 5. FIG. The clipper paper discharge unit 17 is composed of a clipper 18 and a traveling device 19 supported by a vertical lifting device (not shown), a fixed guide 20 and a roller guide 21.
The clipper 18 connects the clipper surface 18a and the pressing surface 18d by a fixing portion 18b made of a spring material and a guide portion 18c, and opens and closes around a fulcrum 18e so as to give a spring force in the direction in which the clipper 18 opens.
Here, the clipper surface 18a is longer than the pressing surface 18d, and in the state where the paper is sandwiched between the clipper surface 18a and the pressing surface 18d (hereinafter this state is referred to as "closed state"), the tip of the clipper surface 18a is the pressing surface. The length is extended beyond the tip of 18d.
The clipper surface 18a has a high friction coefficient. The friction coefficient of the paper is higher than that of the paper, and the frictional force for sending the paper when the clipper surface presses and moves the paper is larger than the frictional resistance acting between the papers.
The traveling device 19 uses a so-called rodless cylinder, and a clipper fixing portion 18b is attached with the slider of the rodless cylinder as a traveling portion 19a. The traveling unit 19a is configured such that the clipper 18 is positioned on the sheet stack at the forward end and the recovery unit 15 at the backward end.
When the clipper 18 is opened at the position where the traveling device 19 is lifted by the up-and-down lifting device, when the clipper 18 travels from the retracted end to the advanced end, the tip of the clipper pressing surface 18d is fixed guide 20 or roller guide 21. The clipper surface 18a pushes the upper surface 1b of the sheet stack when the traveling device 19 is lowered at the forward end of the clipper 18.
The fixed guides 20 are two fixed guides 20 supported by a support (not shown), and the space between the two fixed guides is widened so that the sheet falls. The roller guide 21 is freely supported by a support (not shown).
When the traveling portion 19a is moved backward from the forward end position with the traveling device 19 lowered, the guide portion 18c comes into contact with the roller guide 21, and the clipper 18 starts to close. The portions 18c are arranged in a positional relationship guided by the fixed guide 20. Further, the fixed guide 20 releases the clipper 18 at the retracted end of the traveling portion 19a.
When the traveling device 19 is raised in the clipper discharge unit 17, the traveling unit 19 a is advanced and the clipper 18 is at the forward end and the traveling device is lowered 19, the clipper surface 18 a pushes the upper surface 1 b of the stack of sheets. . When the traveling portion 19a is moved backward in this state, the paper that contacts the clipper surface 18a moves together with the clipper 18, the guide portion 18c is guided by the roller guide 21, the clipper 18 is closed, and the paper is pinched by the clipper 18.
Since the clipper 18 is closed while the guide portion 18c is guided by the fixed guide 20, the paper moves while being sandwiched between the clippers 18 as the traveling portion 19a moves backward, and the clipper 18 is released at the backward end. Therefore, the paper falls and is collected by the collection unit 15.
In the present embodiment, discarding is performed within a range where the high-viscosity fluid does not adhere to the stationary paper plate 3b and the clipper surface 18a. This is to facilitate the discharge of the paper and the separation of the paper from the clipper surface 18a.
Unlike the above embodiment, the clipper can be made of a non-metal or metal other than the spring material and the clipper can be opened with a separate spring, or the clipper can be opened and closed by the rotational force of the motor or the force of the cylinder. .
As for the traveling device, there is a method in which a traveling unit guided by a guide pin or a traveling unit with wheels traveling on a rail is moved by a cylinder or a motor. As for the guide, the portion corresponding to the roller guide 21 described above can be configured with a smooth curved surface only as a fixed guide.
Accordingly, the configurations described or illustrated in the above embodiments are merely exemplary. Any configuration may be used as long as the upper surface of the stack of sheets is pushed by the clipper surface of the clipper, the uppermost sheet is pulled out, and the sheet is sandwiched and further moved.

The top sheet 1a of the sheet stack 1 is sucked to the suction pad 8a by being pressed and the air in the suction pad is pushed out.
When the push-up device 9a of the paper-pressing unit 9 is lowered to lower the paper-pressing plate 9b, the paper stack 1 is lowered together with the paper-pressing plate 9b, leaving only the uppermost paper 1a. Subsequently, when the traveling unit 8 c is moved backward and the traveling unit 8 c comes on the collection unit 15, the inside of the suction pad 8 a is released to the atmosphere, and the sheet 1 a falls and is collected by the collection unit 15.
In this embodiment, disposal is performed within a range in which the high-viscosity fluid does not adhere to the fixed paper-stop plate 10 and the suction pad 8a. This is for facilitating the discharge of the paper and the separation of the paper from the suction pad 8a.

The suction pad is preferably connected to a pressure reducing device to forcibly reduce the pressure, which increases the reliability of suction and is preferable. Also, there are two methods of releasing to the atmosphere: a method of simply opening and a method of forcibly introducing compressed air. Forcibly introducing compressed air has an effect of quickly separating the paper from the suction pad.
In the above embodiment, the lifting device 8b can be directly held by a cylinder or a method using a mechanism such as a pantograph or a telescope can be considered. As for the traveling unit 8c, there is a method in which a cart guided by a guide pin, a cart with wheels traveling on a rail, or the like is moved by a cylinder or a motor.
Accordingly, the configurations described or illustrated in the above embodiments are merely exemplary. Any structure may be used as long as the uppermost sheet of the sheet stack 1 is sucked by a suction pad having a lifting mechanism and is transported in the horizontal direction.
