Description

  The present invention relates to a discharge paper stacking device for stacking paper that is finally printed after being printed or laminated in a printing machine, various gloss machines (hereinafter simply referred to as a laminator), and the like.

Conventionally, in a printing machine, a laminator, and especially a laminator, a stack of sheets that are processed and discharged is manually collected on a simple plate. FIGS. 1A and 1B are a side view and a plan view of a paper take-up stand R provided at the final part of the laminator machine. The flow of the process in the drawing is from left to right, and the laminated paper is finally discharged to the paper take-up stand R installed obliquely on the right side. Then, the worker stands on the right side of the paper take-up stand R, hits the paper discharged randomly one by one against the paper stopper plate 7, and aligns it manually.
Issued by Masayoshi Araki, “All about Converting-From Past to Future-” Processing Technology Study Group, published on June 30, 1993, P629-633 See FIG. 1 and FIG.

In the simple paper take-up stand of the laminator, for example, when aligning papers laminated on both sides with a film (having static electricity), the papers that are randomly ejected to the paper take-up base from one to the next are arbitrary. At the moment of contact with each other, the films are brought into close contact with each other due to static electricity or the like, and overlap as they are. Sheets that are firmly adhered by static electricity cannot be easily arranged, and after all, manual operation cannot keep up with the speed of the continuously ejected sheets, and the sheets overlap each other and cannot be picked up.
Therefore, in order to avoid such a laborious and labor-intensive task, connection of a large-scale device such as a known down stacker that forcibly loads sheets one by one mechanically or a paper aligner that aligns sheets by vibration However, the working side would like to adopt a method in which discharged sheets are easily arranged without using such a large, complicated and expensive apparatus and without being affected by static electricity.

  Therefore, the present applicant has developed “Paper Loading Device” of Japanese Patent Application No. 2004-163883 after intensive research. This ground-breaking invention is a discharge paper stacking device for sequentially loading and storing paper discharged after processing by a paper processing machine such as a printing machine or laminator. A sheet stacking base provided with at least one guide for receiving the sheet, and a guide capable of providing an angle so as to bend the sheet on the side of the sheet stacking base that receives the discharged paper. It is a thing.

  FIG. 2 is a perspective view showing the outline of the invention, and FIGS. 3A and 3B show the operation. According to this, the sheet S to be processed and discharged is almost forcibly bent by the guides 1 and 2 set obliquely. Therefore, the paper S is in a state where the spine passes through the curved apex portion and is not easily bent, so that the paper S does not hang down even if the paper projects into the air. As a result, processing has been completed and contact with the sheets stacked below has been reduced as much as possible, enabling efficient loading.

  However, even in the above-described invention, it cannot be said that the contact between the sheets is completely lost, and the curved surface cannot be maintained in the latter half portion of the discharged paper, and the front surface of the paper is hung down and is already stacked below. It has been found that troubles such as contact with the surface due to static electricity occur.

  In view of such problems, the problem to be solved by the present invention is that the paper that is processed and discharged in a printing machine, laminator, or the like is not affected by static electricity or the like, and the known down stacker or paper aligner. Thus, it is an object of the present invention to provide a compact, simple and inexpensive stacker for discharged paper, which does not require a large, complicated and expensive apparatus.

  In order to achieve the above object, the stacking device of the present invention is a stacking device for discharged paper for sequentially loading and storing processed paper discharged after processing by a paper processing machine such as a printing machine or a laminator. A plurality of guides capable of changing the angle to bend the paper discharged after being processed are provided on the receiving side of the discharged paper at substantially the target position with respect to the center line in the paper discharge direction. A plurality of blowers are arranged at substantially target positions with respect to the center line in the paper discharge direction, and the blower blows air in a state where the lower surface side of the paper is blown up from below the discharged paper. .

  There are no special restrictions on the materials such as guides, paper stacking sections, and paper stop plates (multiple vertical and horizontal positions may be provided so that the paper can be easily aligned), and metals, resins, paper, ceramics, etc. can be preferably used. it can. Moreover, surface treatment by fluorine processing such as silicon or Teflon may be performed on the surface as a countermeasure against static electricity or the like, or an antistatic tape or sheet may be attached to the whole or a necessary portion.

  The guide may be formed by a single plate made of a curved surface, a flat surface, or a mixture thereof, and may be composed of a plurality of guides. Of course, the plurality of guides may also be formed by a curved surface, a straight line, or a surface made of a mixture thereof. The guide does not necessarily have to be a plate-like plane or curved surface, and may be formed by a single or a plurality of rollers so that the paper can move easily, or a slit or louver made of a plurality of fine materials. It doesn't matter.

  Each paper stopper plate may have a shape formed of a flat surface, a curved surface, or a mixture thereof, like the guide. However, this is not always necessary, and it may be formed by a single or a plurality of rollers, or may be a slit or louver made of a plurality of fine materials. Further, it is convenient to form the sheet stopper plate in various arrangements such as left and right, front and rear, top and bottom, and rotation according to the size of the sheet to be processed. Furthermore, a paper stopper plate may be provided to be able to rotate back and forth, left and right or rotate, and the paper stacking part can be extended so that it can handle various sizes of paper. The height of the discharge port of a paper processing machine such as a laminator can be adjusted. It may be formed so that it can be moved up and down so that it can be adjusted, or an angle adjustment function may be added so that slopes of various angles can be formed.

  As the blower, a known device such as a fan or blower can be applied. However, it is convenient if the air volume can be adjusted by the type of paper, the amount of haze, and the like. Further, in the air blowing direction, the paper is discharged in the direction in which the back side of the paper is pushed upward from the lower side of the paper toward the downstream side on the upstream side where the paper advances. A suitable angle of the air blow is about 25 ° (± 15 °) with respect to the vertical line of the paper stacking surface. By setting in such a manner, when the wind forcedly sent from the blower arranged at a substantially target position with respect to the center line in the paper discharge direction is a sheet curved in a U shape, Blowing smoothly passes from the center to both ends, and the entire paper blows up moderately and steadily floats up, so that it does not touch the paper already loaded downward until the end of the discharge operation, and loading is completed without stress Is done. In addition, since the reflected air blows to the end face of the paper that has already been processed and is discharged and stacked, air is sent between the stacked sheets, so that there is no adhesion due to stacking after discharging.

  According to the discharge paper stacking apparatus of the present invention, as described above, the blower device provided at a specific position below the discharge paper passes the air to the leading edge of the paper, and the surface of the paper already stacked below until the end of discharge. Loading without stress is done. In addition, since the reflected air blows to the end of the paper that has already been processed and is discharged and stacked, air is sent into the gap between the stacked paper, so that there is no close contact due to stacking after discharging. In particular, in the case of a U-shaped curved sheet, the air can be smoothly passed from the center of the sheet to both ends, and the entire sheet can be wrapped and can be lifted stably.

FIG. 8 is a side view showing a modified example of the angles of the guides 1 and 2.

  As shown in FIG. 4, the loading device K is provided with guides 1 and 2 that first receive a sheet S (represented by an alternate long and short dash line) pushed out from the direction of the upper right arrow in the drawing (shown in a broken view). Refer to the guides 1 and 2 in FIG. The guides 1 and 2 are attached in such a manner that the angle can be changed around the fulcrum 3 in the direction of the arrow in the figure, and on the lower upstream side of the guides 1 and 2 is approximately the center line X in the paper discharge direction indicated by the broken line in the figure Two fans F are mounted at symmetrical angles at an angle that blows obliquely upward from the bottom of the paper toward the downstream side in the paper transport direction. In addition, the paper stopper plates 5, 6, and 7 provided at the three vertical and horizontal edges on the edge side of the paper stacking portion 4 indicated by diagonal lines are attached so as to be movable left and right and up and down according to the size of the paper S to be processed. Yes. Further, the mounting portion of the guides 1 and 2 and the mounting portion of the rear paper retaining plate 7 can be slid by the slit 13 provided over the entire side of the main body by loosening the screw 12 (not limited to this method). A known sliding method may be adopted), and the front and rear can be extended according to the size of the paper. The stacking device K is connected to the moving unit 9 with the casters 8 and the back of the sheet stacking portion 4 so as to be swingable like a seesaw above the support column 10.

  As in FIGS. 3A and 3B, the loading device K of the present invention is installed with an arbitrary angle α adjusted by adjusting the height of the column according to the height of the discharge port of the laminator or the like. This angle α is arbitrarily set depending on the pass line of the paper S discharged from the laminator, the type and amount of paper S to be processed, the properties of the laminate film, the strength of the air blower, and the like. Then, the paper S discharged from the laminator hangs down by its own weight and is pushed out on the guides 1 and 2. At this time, since the guides 1 and 2 are inclined to the inside of the stacking device K, the sheet S pushed out along the guide advances to the sheet stacking portion 4 while being curved in a U shape. Since the curved sheet S is in a state where a single beam is formed, it does not hang down, and is further wrapped by the fan F from the lower side of the sheet S to both ends as shown in FIGS. 5 (A) and 5 (B). Since the blast passes through the symmetrical route, the air is sent to the end in a state of sliding in the air without contacting the surface of the paper already stacked below. The guides 1 and 2 receive the paper by setting the angle at which the paper S is bent in a U-shaped valley shape, but may be received in a flat state.

  The blower is not limited to a fan, and may blow out by air blow or the like, and a known blower can be selected. Further, if an antistatic measure is taken for the air blowing device, for example, a device capable of blowing ion wind is used, the stacked paper and the discharged paper are neutralized, so that the effect of preventing adhesion between the papers is improved. As shown in FIG. 6, the air blowing direction by these air blowers is a direction inclined by β from the vertical angle of the paper stacking portion 4. As described above, this angle β is preferably in the range of 30 ° ± 15 °.

  By the way, the paper S may land with momentum near the lower paper stopper plate 7. Accordingly, in order to firmly receive the front portion of the paper that hits the paper stopper plate 7 without losing momentum and getting over the paper stopper plate 7, a paper fixing device 11 as shown in FIGS. It is convenient to hang it on the plate 7. If this paper fixing device 11 is made of lightweight aluminum, paperboard, etc., the paper S landing with momentum sinks under the rounded curved surface of the paper fixing device 11 and is therefore automatic even if left alone. Thus, the sheet fixing device 11 is pushed up to the uppermost surface of the sheet S.

  Further, the guides 1 and 2 can be changed not only to change the angle inward and outward by the fulcrum 3 but also to bow before and after the paper traveling direction as shown in FIG.

  The discharge paper stacking apparatus of the present invention can be installed behind a machine that discharges processed paper. Therefore, it can be combined with machines in a wide range of fields such as printing machines and paper folding machines, not limited to the laminator of the embodiment.
