Description

The present invention relates to a sheet stacking device. More particularly, the present invention relates to a stacking apparatus capable of forming a stacked body without sheet-shaped bodies protruding upward from the stacked body when stacking a large number of sheet-shaped bodies.

For example, an apparatus for stacking a large number of sheets such as printed sheets to form a stack of sheets is well known, and is described, for example, in Japanese Patent Laid-Open Publication No. 2002-200012.

This apparatus 100A is as shown in FIG. 3. A sheet-like material s is sandwiched between two opposing conveying belts 21A and 22A, and these two opposing conveying belts 21A and 22A are tilted and moved upward. Thus, the surface of the sheet-like body s is set up so as to form a vertical plane. A stacking table 30A is arranged at the end of the transport belts 21A and 22A in the running direction, and one of the two opposing transport belts 21A and 22A, the transport belt 22A, and a presser arranged opposite to the transport belt 22A. The sheet-like bodies s are vertically stacked between the support plate 40A. In this stacking device 100A, the presser support plate 40A is lightly pressed by the pressurizing means 50A, and as the amount of the stacked sheet-like materials s increases, the presser support plate 40A retreats toward the left side of the drawing. It is Further, a backing plate 10A is arranged on the stacked body S so that the sheet-like body s does not protrude upward from the stacked body S. As shown in FIG.

Japanese Patent No. 2817384

As described above, in the stacking device 100A, the backing plate 10A is arranged to prevent the sheet-like body s from protruding upward. Moreover, since the sheet-like material s is pressurized, once the sheet-like material s protrudes from the stack S, it is impossible to return the sheet-like material s thus protruding.

The present invention has been made on the basis of such a technical background. Therefore, it is an object of the present invention to provide a stacking device capable of forming a stack without sheet-like members protruding upward from the stack.

That is, the invention according to claim 1 is an apparatus for forming an assembly by stacking a large number of sheet-like bodies in an upright state so that the surfaces thereof constitute a vertical plane,
a tidying device that abuts on the upper end surface of the stack and aligns the upper end surfaces of the plurality of sheet-like bodies;
The tidying device comprises an arm that abuts on the upper end surface of the stack and a shaft that supports the arm in a cantilevered state, and a vibrating device that vibrates the arm about the shaft. It is a sheet-like object stacking device characterized by having

The integrated device of the present invention may further include a sensor that senses the rotation angle of the arm.

In addition to this, the stacking device of the present invention can also comprise a vibrating device for vibrating the stack.

According to the present invention, since the arm is brought into contact with the upper end surface of the stack of many sheet-like materials and has a vibrating device for vibrating the arm, when the vibrating device is operated, the arm rotates its axis. oscillate as a center. Therefore, when there is a sheet-like object projecting upward from the stack, the vibration causes the arm to hit the tip of the sheet-like object projecting upward, and the sheet-like object can be returned into the stack. can. As a result, it is possible to form a stack without sheet-like bodies protruding upward.

If the stacking device is provided with a sensor for detecting the rotation angle of the arm, the sheet-like material protruding above the stack can be recognized by the change in the rotation angle of the arm that abuts on the upper end surface of the stack. can do. Then, the vibrating device can be operated only when the sheet-like body protruding upward in this way is recognized.

Further, when the stacking device is provided with a vibrating device for vibrating the stack, the vibration can loosen the close contact between the sheets. It will be easier to put it back inside.

FIG. 1 is a cross-sectional explanatory view of an integrated device according to an embodiment of the present invention. 2A and 2B are cross-sectional explanatory views of the main part for explaining the operation method of the stacking device according to the embodiment of the present invention. FIG. 2B shows a state in which the protruding sheet-like body is returned to the stack and the arm vibration device is stopped. FIG. 4 is a cross-sectional explanatory diagram of a main part; FIG. 3 is a cross-sectional explanatory view of a conventional integrated device.

The present invention will now be described with reference to the accompanying drawings. FIG. 1 is a cross-sectional explanatory view of an integrated device 100 according to an embodiment of the present invention. 2A and 2B are cross-sectional views of essential parts for explaining the operation method of the stacking device 100 according to the embodiment of the present invention. FIG. 2(b) shows a state in which the protruding sheet-like material is returned to the stack and the arm vibration apparatus is stopped. .

As shown in FIG. 1, this stacking device 100 is the same as the conventional stacking device 100A except that a tidying device 10 for aligning the upper end faces of the sheet-like bodies s is provided instead of the backing plate 10A. That is, in the stacking device 100 as well, the sheet-like material s is sandwiched between the two opposing conveying belts 21 and 22, and these two opposing conveying belts 21 and 22 are tilted and moved upward, whereby the sheet-like material is Assume that the body s is set up so that its surface constitutes a vertical plane. A stacking table 30 is disposed at the end of the transport belts 21 and 22 in the running direction, and one of the two opposing transport belts 21 and 22, the transport belt 22, and a presser arranged opposite to the transport belt 22 are arranged. The sheet-like bodies s are vertically stacked between the supporting plate 40 and the support plate 40 . The presser support plate 40 is lightly pressurized by the pressurizing means 50, and the presser support plate 40 retreats toward the left side in the drawing as the amount of the stacked sheet-like materials s increases.

A tidying device 10 for aligning the upper end faces of the sheet-like bodies s is arranged on the stack S. As shown in FIG.

As shown in FIG. 2, the tidying device 10 has a column 11 erected on a stacking table 30, and an arm 13 is fixed to a shaft 12 arranged on the column 11. As shown in FIG. The arm 13 is supported by a shaft 12 in a cantilevered state and can freely rotate around the shaft 12 . Therefore, the tip of the arm 13 is in contact with the upper end surface of the stack S. As shown in FIG. The shaft 12 can be moved vertically by sliding it along the column 11, and can be stopped at an arbitrary position to adjust the height of the arm 13. FIG.

A vibration device 14 is fixed to the tip of the arm 13 and also serves as a weight. By operating the vibration device 14, the arm 13 can be vibrated. The direction of vibration is the direction of rotation about the axis. In addition to the vibration device 14, it is also possible to fix another weight.

Further, the shaft 12 has a built-in sensor for sensing the rotation angle of the arm 13 . When there is a sheet-like body s protruding above the stack S, the rotation angle of the arm 13 in contact with the upper end surface of the stack S changes. , the presence of the sheet-like body s projecting upward from the stack S can be recognized. When the presence of the sheet-like body s protruding upward is recognized by this sensor, the vibrating device 14 is operated, and when such a sheet-like body s is not detected, the vibrating device 14 is stopped. can be done.

A stopper 15 is provided below the arm 13 so that the swing width of the arm 13 due to vibration does not become excessive.

As is clear from the above description, this integrated device 100 can be used as follows. That is, first, as shown in FIG. 2A, when the sensor recognizes the sheet-like body sx projecting above the stack S from the change in the rotation angle of the arm 13, the vibration device 14 is operated. The arm 13 is vibrated. Since the arm 13 vibrates about the shaft 12 in a rotating direction, the arm 13 repeatedly hits the projecting portion of the sheet-like material sx projecting upward in the direction of returning it to the inside of the stack S from the tip thereof.

Then, when this sheet-like body sx returns to the inside of the stack S and the upper end face of the stack S is aligned, the sensor does not recognize the sheet-like body sx projecting upward from the stack S, so the vibrating device. 14 stops and the arm 13 also stops vibrating (see FIG. 2(b)).

As described above, according to the stacking apparatus 100 of the present invention, when there is a sheet-like material sx projecting above the stack S, the arm 13 vibrates to return the sheet-like material sx to the inside of the stack S. As a result, it is possible to form the stack S without the sheet-like body projecting upward.

The stacking device 100 may further include a vibrating device (not shown) for vibrating the stack S. As shown in FIG. This vibrating device can vibrate the stack S indirectly by, for example, installing it on the stacking table 30 and vibrating the stacking table 30 . It is also possible to vibrate the stack S indirectly by scattering vibration devices on the pressing support plate 40 and vibrating the pressing support plate 40 . In any case, by vibrating the stacked body S, the close contact between the sheet-shaped body s and the adjacent sheet-shaped body s can be loosened at the moment of the vibration, so that the vibration of the arm 13 causes the stack to protrude upward. Returning the sheet-like body sx to the stacked body S becomes easier.
