Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper handling method for handling a large number of stacked sheets of paper so that they can be easily peeled or separated, for example, before printing.

"Prior art" Conventionally, this type of paper handling method was disclosed in Japanese Patent Application Laid-open No. 58-193.
As disclosed in Publication No. 851, the stacked sheets are held by a fork and turned over vertically, and the fork is tilted while the sheets are in an upright position, causing air to flow in from below. It is known that it infuses

``Problems to be Solved by the Invention'' However, with this method, not only is it not possible to continuously handle a large number of sheets one after another, but also the method does not work on the side edges of the sheets, which are particularly sticky. Since it does not peel or separate by applying external force, it cannot be peeled or separated accurately, and it cannot be applied to wrapped sheets of paper.

It is an object of the present invention to be able to continuously handle a large number of sheets one after another, to peel or separate them accurately by actively applying an external force to the side edges, and to be able to handle wrapped sheets. The objective is to provide a novel paper handling method that can also be applied to paper.

"Problems to be Solved by the Invention" The paper handling method of the present invention basically involves stacking a large number of sheets on a lifter, raising them to a predetermined height, and then placing a predetermined number of sheets on the top shelf. One side edge of the sheet bundle is flipped up using a flip-up device, and both ends are lifted up using a lifting device and bent into a U-shape, thereby shifting the one side edge relative to each other, and in this state, both ends are lifted up. Particularly in the case of thin and so-called weak sheets, which are characterized by being held in the clamp hand by lowering the clamp hand and stretching again, after the sheet bundle is stretched again as described above, It is temporarily folded back from one end corner by a folding device.

In the case of wrapped sheets, they are stacked on a lifter in multiple tiers and raised one tier at a time, and one side edge of the top tier of wrapped sheets is pushed out by a pushing device to the lower tier. After extruding from the packaging sheet and removing the packaging sheet by adsorption with a suction device, perform the same operation as in Section 2.

"Function" According to the method of the present invention, the sheets stacked on the lifter are lifted up to a predetermined height by the lid, and the top stack of sheets is flipped up one side edge by the flip-up device. After being separated from the underlying sheet, it is lifted by a lifting device and bent into a U-shape, thereby shifting one side edge relative to the other. By holding both ends of one side edge that has shifted in this way and stretching it again, the sheets will be stretched to a different degree, and the center portions will curve with different curvatures, causing the paper to stretch between the sheets. A curved void is formed, allowing air to enter and loosen it.

After inflating in this way, if the stack of sheets is temporarily folded back from one end corner using a folding device, it is possible to accurately release the adhesion of the sheets at the side edges, and also to prevent the sheets from sticking at the side edges. Rigidity can be increased (so-called waist-fitting).

In the case of wrapped sheets, the wrapping sheet can be removed by suction using a suction device and then loosened in the same manner as described above.

The paper sorting device is constructed as described above, and the method of the present invention carried out using this device will now be described.

The sheet 6 wrapped in a packaging sheet is cut on the periphery of the packaging sheet in advance and placed in the upper and lower packaging sheets 91a, 91b (
The packages are stacked in multiple stages on the I-shipping side table lifter 7 in a separated state (Fig. 8.8), and are lifted one packaging stage at a time by the table lifter 7.

When raised by one packaging stage, the left and right portal frames 1.2
The traveling frame 19 on the right side is positioned outside the gap (solid line position in Figure 1) and is moved to between the left and right portal frames 1.2 by the operation of the rodless cylinder 27, and the pushing device 22 attached thereto is moved between the left and right portal frames 1.2. and the upper packaging sheet suction device 21 are located between the left and right portal frames 1.2.

At this position, as shown by the solid line in Figure 8, the extruded long plate 3
3 is lowered by the vertical movement cylinder 32 and then horizontally slid to the right by the horizontal sliding cylinder 29, so that the sheet bundle 6 for one package on the top tier is moved to the right by the push-out elongated plate 33. This causes the right long edge to protrude to the right from the stack of sheets 6 below. At the same time, the suction cup mounting frame 35 is lowered by the vertical movement cylinder 36, and the suction cup 37 attracts the upper packaging sheet 91a of the uppermost stack of sheets 6. After this, the extruded long plate 33
After the suction cup mounting frame 35 is raised and the traveling frame 19 is returned as shown by the chain line in the figure, the suction of the suction cup 37 is released, and the upper packaging sheet 91a falls into the dust basket 92. be done.

After the upper packaging sheet 91a is removed in this way or during the removal operation, the right lifting cylinder 24
The right lifting frame 11 is raised by
As shown by the chain line in FIG. 9, the suction cup 44 is raised by the cylinder 43 for vertical movement of the suction cup, and after this suction cup 44 has sucked the packaging sheet 9]b on the lower side of the uppermost stack of sheets 6, it is lowered again. As shown by the solid line in the figure, the right long edge of the lower packaging sheet 91b is pulled down.

Thereafter, as shown in FIG. 10.11, the flip-up plate 40 is immediately rotated upward by the flip-up cylinder 41, and the uppermost stack of sheets 6 is pushed out as described above.
Flip up the center part of the right long edge.

At the same time, the advancing/retracting cylinders 50 of the pair of lifting devices 15 are operated, and the pair of clamp hands 49 are advanced toward the sheet stack 6. At this time, both clamp hands 49 are located inside each other on the tilting rail 47, and as shown in the same figure, between the open upper and lower fingers 49a, the sheet bundle is flipped up as described above. The right long edge of 6 enters. Thereafter, the flip-up plate 40 returns downward and rotates, so that the right long side edge of the stack of sheets 6 is held in the flip-up position by the lower fingers 49a. In this state, both clamp hands 49 are slid outward from each other along the tilting rail 47 by the motor 51 with an electromagnetic brake. When both clamp hands 49 reach the outer ends of the tilting rails 47 and stop, both the movement cylinders 48 are operated simultaneously, and both the tilting rails 47 are tilted upward to form a V-shape with each other, as shown in FIG. become. As a result, both ends of the stack of sheets 6 are lifted as shown in FIG. 19, and the right long edges are bent in a U-shape, and the right long edges 6a of the sheets are slightly tilted. It shifts.

When the sheet stack 6 is held in this state, the left running frame 18 is moved by the drive of the running motor 25.
The stack of sheets 6 is moved to the right between the left and right portal frames 1.2, and the lower clamping plates 64 of the front and rear clamp arms 60 of the transfer device 20 are lifted up, as shown by the chain lines in FIG. , the upper and lower fingers 49a of both clamp hands 49 are closed, and both ends of the right long edge of the sheet stack 6 are moved between the upper and lower fingers 49a with the edge 6a shifted as described above. It is held between Immediately thereafter, both the tilting rails 47 are rotated downward, so that the right long edge of the stack of sheets 6 is held by both clamp hands 49.
It is stretched again while being held in the arms. Since the right long edges 6a of the sheets are stretched again while being held in a shifted state as described above, the degree of stretching is shifted, as shown in FIG. (the curvature gradually decreases from the lower side to the upper side), and a curved gap is formed between them, into which air enters and is removed.

When the sheet stack 6 is stretched out again in this way, the clamping by the upper and lower fingers 49a is released, and then the advancing/retracting cylinder 50 moves back the forward/backward sliding table 46, and both clamp hands 49 move the sheet stack 6 By being removed from the sheet stack 6, the front and rear short edges of the sheet bundle 6 are placed on the left and right lower holding plates 64.

Next, as shown in FIG. 13, the first stage cylinder of the front and rear two-stage bending cylinders 69,70 is operated, so that the frames 61 of both clamp arms 60 are
It is rotated by a step, and the front and rear short edges of the sheet stack 6 are flipped up by the front and rear lower holding plates 64. This causes a shift in the short edges 6b of the sheets.

Thereafter, the front and rear clamping cylinders 68 operate simultaneously, and the front and rear short edges of the stack of sheets 6 are clamped by the upper and lower clamping plates 65°64 with the short edges 6b shifted as described above. (same figure). In this state, the front and rear vertical sliding cylinders 59 operate to raise the front and rear vertical sliding frames 58 at the same time, so that the sheet stack 6 is lifted up to a predetermined height while being gently bent. 2
When the second stage cylinder of the step bending cylinders 69, 70 is activated and both the front and rear clamp arms 60 are further rotated in the same direction, the sheet stack 6 is bent as shown in FIG. is bent upward while holding both short edges thereof, and the whole is curved into a gentle M-shape.

As a result, the center portions of the sheets curve downward with different curvatures, and air enters the curved gaps.
mutually relaxed. Further, the sheet bundle 6 is curved into an M-shape and clamped by turning both clamp arms 60 diagonally upward, so that it is prevented from coming off from both clamp arms 60.

Next, the sheet stack 6 is curved into an M-shape and lifted, and as it travels to the left of the left traveling frame 18, it is fed 1 ull to above the folding device 12, where it As both the front and rear vertical sliding frames 58 are lowered, both the front and rear clamp arms 60 are rotated to return, and the upper clamping plate 65 is rotated to return to the upper position, whereby the stack of sheets 6 is released from clamping. It is unfolded and the left long edge is placed on the folding arms 54 of both sets of folding devices 12. With this development, the air that has been trapped between the central portions of the sheets is diffused and discharged toward both front and rear ends, so that the sheets are loosened over their entire surfaces.

As shown in FIG. 15, the sheet bundles 6 placed on the folding devices 12 of both sets are rotated upward by the folding cylinders 55, starting from the outer one. As shown in FIG. 22, after the left long side edge is gradually folded upward from the both end corners, the folding arm 54 rotates back downward, thereby restoring itself and unfolding again. . This increases the rigidity of the sheet by leaving an upwardly curving warp or crease (so-called waisting), and also shifts its left long edge over almost its entire length, so that the sheet has a mutual relationship at its lateral edge. Adhesion is removed accurately. The number of folding devices 12 to be operated is determined depending on the length of the sheet.

Thereafter, the stack of sheets 6 is again held at its both short edges by the upper and lower clamping plates 65, 64 and lifted into a state similar to that shown in FIG. 14, again introducing air between the sheets. It will be done. As the left traveling frame 18 returns to its original position, the left long edge of the sheet bundle 6 changes as shown in FIG.
It is conveyed onto the transshipment side table lifter 7 until it comes into contact with the long side positioning ruler plate 75, and at this position, the upper clamping plate 65 returns upward and is released from the clamping, and then horizontally on both front and rear sides. When the sliding frames 56 are mutually slid outward and the lower clamping plate 64 is removed, the table lifter 7 on the transfer side is loaded.

In this way, the stack of sheets 6 is placed on the table lifter 7 on the transshipment side.
17, the vertical movement frame 78 is lowered by the vertical movement cylinder 79 of the long side alignment device 72, and then the alignment plate 81 is moved to the long side position by the alignment cylinder 79. By sliding toward the ruler plate 75, the right long edge of the stack of sheets 6 is pulled by the alignment plate 81, and both left and right long edges are aligned. Further, as shown by the chain line in FIG. 18, after the movable ruler plate 85 is advanced to a predetermined position by the short side positioning cylinder 84 of the short side positioning device 73, the pressing cylinder 87 of the short side pushing and aligning device 77 moves the movable ruler plate 85 forward to a predetermined position. The pushing and aligning plate 88 is advanced, and by pushing the front short edge of the stack of sheets 6, both the front and rear short edges of the sheets are aligned.

After that, the pulling and aligning plate 81 is retracted and raised and returned, the movable ruler plate 85 and the pushing and aligning plate 88 are retreated and returned, and the transshipment side table lifter is lowered by 7 months to produce one package of sheets. After the work on the sheet bundle 6 is completed, the same work is performed on the next stage sheet bundle 6 on the 1M entry side table lifter 3, and the same work is repeated thereafter.

Although the embodiment described in item 1 is a case of wrapped sheets, in the case of sheets stacked on the carry-in side table lifter 3 as is without being wrapped, the upper packaging sheet suction device 21
The extrusion device 22 is not used and is kept in the solid line position in FIG. 1, and the lower packaging sheet suction device 13 is also not used and its suction cup 44 is kept in the lower position.

Then, as shown in FIG. 23, after flipping up the central part of the right long edge of a predetermined number of sheets 6 in the uppermost stage by the flipping plate 40 of the flipping device 14, as shown in FIG. The lifting devices 15 are moved forward to position the raised right long edge between the upper and lower fingers 49a of the clamp hands 49, and the rest of the process is similar to that described above. In this case, if both short edges of the sheet 6 are flipped up at the same time, it is difficult to make the number of sheets flipped up on both sides the same, but if the central part of the long edge is flipped up, such a problem does not arise.

Note that in the case of relatively thick sheets, the folding device 12
You may omit the return work. Folding device 1
The sheets stiffened by the method 2 have increased rigidity and are left with a curvature on both sides, so that the curvature acts like a blade when feeding the paper to a printing machine, etc., and it is sent straight forward. be able to. In addition, sheet folding is done by holding the corners of the sheet with a clamping device and pulling it diagonally, gradually and gently folding it back, and pressing the top of the sheet intermittently with a device to further fold it. You may go.

Furthermore, the stack of sheets that have been inflated may be directly sent to a printing machine, etc., without being loaded on the table lifter 7 on the transfer side, and in the above embodiment, the stacking height of the sheets is Although we tried to adjust the height, you can also use other glue lids other than the table lifter.

"Effects of the Invention" As described above, according to the paper sorting method of the present invention, after flipping up one side edge of a large number of sheets stacked on a lifter to separate a predetermined number of sheets, the lifting device By lifting the paper sheet and curving it into a U-shape, one side edge is shifted from the other, and in this state, by holding both ends and stretching it again, the central part of the sheet is curved to have a different curvature. This allows air to be forced between the paper sheets, allowing a large number of sheets to be handled one after the other continuously and precisely.

According to the method of the present invention as set forth in claim 2, the side edges of a sheet of paper can be temporarily folded back, so that the side edges of even thin and so-called weak sheets of paper can be loosened accurately. In addition to being able to do so, you can also put it on your waist.

According to the method of the present invention as set forth in claim 3, even if a wrapped sheet of paper is used, after the wrapping sheet is automatically removed,
It can be handled.
