Description

[Detailed description of the invention] [Industrial application field]

In the present invention, before applying to a printing machine or the like, wrapped sheets (wamps) wrapped in a predetermined number of sheets, or unwrapped sheets that are stacked as they are without being wrapped, are The present invention relates to a paper sorting device that automatically sorts each predetermined number of sheets and then stacks them again.

[Prior Art] Conventionally, sheets of paper (wrapping sheets) wrapped in wamps, which are packaging sheets, are stacked in multiple tiers, and the wamps are opened by pushing them out from the top layer (the top of the stack). As an apparatus for stacking opened sheets again, there is known, for example, the apparatus described in Japanese Patent Application Laid-open No. 11330/1983. This device cuts the wamp by pushing the topmost packaging sheet out of the packaging sheets loaded on the table lifter, and continues to vacuum and separate the cut wamp vertically. By pushing, the opened sheets are once transferred onto a roller conveyor, and then the roller conveyor is retracted forward and stacked again on another table lifter.

[Problem to be solved by the invention]

However, since this conventional device simply pushes the trailing edge of the uppermost packaging sheet to separate it from the lower packaging sheets, the separation cannot be performed smoothly. In addition, since the sheets of paper that have been opened are piled up without being separated, the sheets are fed overlapping each other when they are put through a printing machine, etc., so to prevent this, when putting them through a printing machine, etc. There are problems such as the need for a separate paper handling process. The purpose of the present invention is to solve these problems,
In addition to being able to smoothly separate the stacked packaging sheets from the top stacked packaging sheets from the packaging sheets below,
To automatically and efficiently separate opened sheets of paper when stacking them again.

[Means to solve the problem]

The present invention provides a lift table 4 that loads sheets of paper and raises them by a predetermined height, and a lift table 4 that
There is a pushing mechanism 9 which pushes the rear end of the topmost stacked sheet with a pushing body to move it forward, and a pushing mechanism 9 which cuts the left and right sides of the packaging sheet wrapping the sheets as it moves forward. A side cutter 23, a front cutter 26 that cuts the front surface of the packaging sheet after stopping its forward movement, and an upper and lower opening body that sucks the top and bottom surfaces of the cut packaging sheet in front of the lift table 4 and displaces them upward and downward, respectively. 30, 21
, a loading table 48 that is movable up and down in front of these opening bodies 30 and 21, and a loading table 48 that is installed between the loading table 48 and the upper and lower opening bodies 30 and 21, and a stacking table 48 that moves the topmost sheet of the stack forward. It is designed to run back and forth between the drawer mechanism 37, the upper and lower opening bodies 30, 21, and the loading table 48, and the sheets pulled out by the puller mechanism 37 are loaded onto the loading table 48. This is a sheet unsealing and stacking machine having a conveying table 38 that transfers the sheets onto the stacking table 48 by moving forward to a point where the sheet is moved forward and then moving backwards to transfer the sheets onto the stacking table 48. This machine is equipped with the following mechanism. The pushing mechanism 9 is provided with an air nozzle that moves together with the pushing body and injects air between the uppermost stacked sheet and the lower sheet. The above-mentioned lift table 4 and the above-mentioned upper and lower opening bodies 3
A hollow guide table 20 is installed between the guide table 20 and the guide table 20 for guiding the sheets pushed forward by the pushing body. The left and right air injection nozzles 47 are provided to inject air onto both the left and right sides of the sheets stacked on the stacking table 48 as the transport platform 38 retreats.
It is attached to both left and right sides of the front end of the conveyance table 48.

[Effect]

According to the paper sorting device of the present invention, when pushing and separating the top packaging sheet or the top non-wrapping sheet among the stacked packaging sheets, the Since air is continuously injected between wrapped sheets or unwrapped sheets while being pushed,
The separation occurs smoothly. In addition, while being pushed in this way, it is slid on the guide table 20 and transferred onto the conveyor table 38 via this guide table 20, and at this time, the guide table 20 is made hollow and the inside of the guide table 20 is moved. Since air is injected through the air injection holes 20a on the top surface, the sheets can be pushed and separated even more smoothly, and the sheets can also be transferred smoothly onto the conveyor table 38. Further, when the sheets are unloaded from the conveyance table 38 and stacked again, air is injected from the left and right sides of the front end of the sheet onto both the left and right sides of the sheets by the air nozzle 47 while the conveyance table 38 is moved backward. Since air is blown between the sheets from both the left and right sides, the paper can be separated efficiently.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings. A sheet opening/loading machine equipped with a paper sorting device according to the present invention has a lifting/pushing section 1 as shown in FIGS.
It is roughly divided into an unpacking/conveying section 2 and a loading/aligning section 3. A lift table 4 is suspended horizontally at its four corners by a chain 5 on the lifting/pushing part 1, and a sprocket wheel 6 meshing with the chain 5 is connected to the lift table 4 by a motor. When rotated, it is raised while remaining horizontal. The packaging sheets 8 wrapped in the wrapper 7 (FIG. 8), which is a packaging sheet, are loaded onto the lift table 4 by a forklift or the like while being stacked in multiple stages on a pallet. Unwrapped sheet 8a (Figure 7)
In this case, the items are placed on the lift table 4 while remaining on the pallet. The lifting/pushing unit 1 also has a positioning mechanism on its upper part that positions the packaging sheets 8 in the uppermost stage (the top of the stack) from side to side, and a mechanism for opening and transporting the positioned packaging sheets 8. A pushing mechanism 9 that pushes toward the part 2 side and a wamp ejection mechanism 10 that ejects the wamp 7 after opening are arranged as follows. As shown in FIG. 3, the positioning mechanism includes a vertical ruler plate 11 on the right side, a ruler adjustment mechanism 11a for adjusting its position, and a plurality of positioning pushers 12 on the left side.
and a positioning screw 1 that propels it to the right.
3 and a positioning motor 13a that rotates this, and the pushing body 12 moves the top packaging sheet 8
The left end is pushed and the right end is brought into contact with the ruler plate 11 for positioning. As shown in FIG. 4, the pushing mechanism 9 includes a pushing screw 14 which is rotated by a pushing motor 9a (FIGS. 1 and 2), and which is screwed together and rotates along the guide rod 15. A sliding plate 16 that slides back and forth along the sliding plate 16, and a pair of pushing bodies 18 for wrapped sheets or a pair of pushing bodies 17 for unwrapped sheets (FIG. 5) that are vertically installed on the sliding plate 16. Consists of. These pushing bodies 17 and 18 are replaced by a sliding plate 16.
When a wrapped sheet 8 is placed on the lift table 4, a pushing body 18 for wrapping sheets is used, and when an unwrapped sheet 8a is placed on the lift table 4, a pushing body 18 is used. A pushing body 17 for packaging sheets is used. As shown in FIGS. 4 and 6, the packaging sheet pusher 18 has a rod ₁₈₂ vertically slidably vertically disposed on a mounting block ₁₈₁ , and a pusher ₁₈ is attached to the lower end of the rod 182. ₃ is fixed, and this pusher 18 ₃
is urged downward by a spring ₁₈₄ wound around the rod ₁₈₂ . The front surface 18a of the pusher ₁₈₃ is inclined backwardly, and a protrusion 18b is formed at the lower end of the inclination. Also, pusher 18 ₃
An air nozzle 19 that injects air forward is attached to the air nozzle 19, and air is supplied to the air nozzle 19 through a hose. This packaging sheet pushing body 18 has its mounting block ₁₈₁ mounted on a sliding plate 1.
6 by using bolts and nuts to hang it there. As shown in FIG. 5, the pusher 17 for unwrapped sheets has a rod 172 vertically vertically adjustable on a mounting block ₁₇₁ , and _{a pusher 173 is} fixed to the lower end of the rod ₁₇₂ . This is what I did. This pusher 17 ₃
has a U-shaped side surface, and a plurality of air injection holes 17b are provided at the front edge of the lower plate portion 17a, and an air passage communicating with the air injection holes 17b is provided inside. When the air is supplied, air is injected all at once from the air injection holes 17b. When the packaging sheets 8 are stacked in multiple stages on the lift table 4, the lift table 4 rises and the rear end of the packaging sheet 8 on the top tier is pushed by the packaging sheet pushing member 18. It collides with the front surface 18a of the child 18 ₃ and raises it slightly against the spring 18 ₄ .
When the top surface of the stack of packaging sheets 8 rises to a predetermined position, this is detected by the sensor and the lifting operation of the lift table 4 is stopped. Thereafter, when the screw 14 rotates and _{the sliding plate 16 and the pusher 183 are} propelled forward as shown in FIG. The packaging sheet 8 is pushed forward while being in contact with the rear end of the sheet 8. During this pushing, the top packaging sheet 8 and the packaging sheet 8 one stage below it
Since air is injected from the air nozzle 19 between the top and bottom packaging sheets 8, the top packaging sheet 8 smoothly slides over the packaging sheet 8 one stage below. Further, since the front surface 18a of the pusher ₁₈₃ is inclined as described above and is urged downward by the spring ₁₈₄ , when the pusher 183 is stopped, the rear end of the uppermost packaging sheet 8 Even if the position of the pusher 183 is slightly deviated or the thickness thereof is different, as long as the pusher ₁₈₃ moves forward, the engagement between the protrusion 18b and the rear end of the packaging sheet 8 will be achieved accurately. Moreover, the engagement will not come off during pushing. The positioning pusher 12 of the positioning mechanism is also mounted in the same manner as the packaging sheet pusher 18, and an air nozzle is also attached thereto, and the push operation for positioning is performed in the same manner as above. It will be done. When unwrapped sheets 8a are loaded on the lift table 4, a pushing body 17 for unwrapped sheets is attached to the sliding plate 16. In this case, when the uppermost loading area of the unwrapped sheets 8a reaches a predetermined position and the lifting of the lift table 4 stops, the pusher 17 moves forward and the lower plate part 17a of the pusher ₁₇₃ moves the unwrapped sheets. Cut into the rear end of the top end of the stack of sheets 8a,
A predetermined number of unwrapped sheets 8a above the interruption area are pushed forward with their rear ends held by the pusher ₁₇₃ as shown in FIG. . At this time, since air is injected from the air injection hole 17b at the front end edge of the lower plate part 17a of the pusher ₁₇₃ , the lower plate part 17
A smoothly enters the upper end of the stack of unwrapped sheets 8a, and a predetermined number of unwrapped sheets 8a whose rear ends are held by the pusher ₁₇₃ are inserted into the unwrapped sheets 8a below. 8a, it is smoothly separated and moved forward. The wamp discharge mechanism 10 operates in the final process when processing the packaging sheet 8, and its configuration will be described later. Next, the unsealing/conveying section 2 will be explained. The uppermost packaging sheet 8 has been pushed forward by the packaging sheet pusher 18 as described above.
is a horizontal guide table 20 as shown in FIG.
The user rides on the oblong lower opening body 21 which is in a horizontal state by sliding on the top, and the front end collides with the front opening position stopper 22 (see Fig. 10) provided protrudingly from the tip of the lower opening body 21. and stop. Information table 2
0 is hollow as shown in FIG. 8, and a large number of air injection holes 20a are provided on its upper surface and curved rear end surface, and air is ejected from the air injection holes 20a to the packaging sheet 8. Because of this, it slides smoothly on the guide table 20. While the packaging sheet 8 is moving forward until it collides with the front opening position stopper 22, the right and left sides of the wamp 7 are automatically cut by the horizontally rotating disk-shaped left and right side cutters 23 as it moves forward. be cut off. These side cutters 23 are individually rotated by a cutter motor 24, and their positions do not move back and forth, but they can be adjusted to the left and right at the same time by a screw mechanism 24a. It is designed so that it can be evacuated to the far left). The packaging sheet 8, whose front end has been positioned by the front opening position stopper 22, is moved to the wamp 7 by a disc-shaped front cutter 26 that slides leftward or rightward along the cutter rail 25 while rotating horizontally. The entire length of the front side is cut off. A cutter motor 27 for rotating the front cutter 26 is attached to a cutter slider 28 mounted on the cutter rail 25, and the cutter slider 28 is slid by, for example, a chain drive. This front cutter 26 can also be retracted to an inactive position (right end or left end) where it does not perform any opening operation. When the front ends of the right and left sides and the entire length of the front surface of the wamp 7 are cut in this way, the plurality of lower suction cups 29 attached to the lower opening body 21 and the plurality of upper suction cups attached to the upper opening body 30 are cut. Air suction by the suction cup 31 starts, and the lower surface and the upper surface of the wamp 7 are attracted to the upper surface of the lower opening body 21 and the upper suction cup 31 by the suction by these suction cups 29 and 31. The lower suction cup 29 is attached to the lower side of the lower opening body 21, and its suction hole 3 is attached as shown in FIG.
2 is on the way. The upper suction cup 31 is the upper opening body 3
0 protrudes from the bottom surface. The lower opening body 21 has its left and right ends pivoted on shafts 33, and is rotated up and down by a motor or cylinder (not shown), and the upper opening body 30 is rotated up and down by the cylinder. At multiple locations on the left and right of the lower side of the lower opening body 21,
The air injection needle 34 is a cylinder 34a for operating the injection needle.
It is attached so that it can be moved forward and backward by a screw, and air is injected from this. When the wamp 7 is attracted as described above, the lower opening body 21 rotates downward as shown by the chain line in FIG. 8, and the upper opening body 30 rotates upward, so that the front end has already been cut off. The wamp 7 is divided into upper and lower cut parts 7a and 7b along the cutting line, and is opened by turning both the upper and lower parts so that the front end is open and the sheets inside the wamp 7 are opened. The front end of 8' is exposed. At this time, the injection needle actuating cylinder 34a is activated, and the air injection needle 34 protrudes forward from the small hole of the lower opening body 21.
It pierces the lower cut portion 7b at multiple locations on the left and right from the rear side, and injects air toward the front. Further, as the lower opening body 21 rotates downward, the exposed front end of the sheet 8' is curved and hangs downward from the guide table 20, and the front end and the lower part of the wamp 7 Air is blown from the air injection needle 34 between the cut portion 7b and the cut portion 7b. The sheet 8' with its front end hanging down in this way is
Its front end is lifted to a horizontal state by an L-shaped lifting piece 36 of a lifting mechanism 35.
At this time, since air is injected from the air injection needle 34 as described above, even if the front end of the lower part of the sheets 8' is separated,
It is pushed up by an air jet and the whole thing is lifted up. The lifting pieces 36 are fixed to a plurality of positions on the left and right sides of a horizontal shaft 36a that is rotated by a motor or a cylinder. The sheet 8' whose front end has been lifted is moved to the pull-out mechanism 37 as follows.
is pulled out from the wamp 7 forward and placed on a gondola-shaped conveyance platform 38. The pull-out mechanism 37 transmits the rotation of the pull-out/conveyance motor 39 to the pull-out screw 40 via the transmission mechanism, and the rotation of the screw 40 causes the clamp slide table 41 to be moved onto the clamp rail 42 (FIG. 11). Slide it back and forth. This clamp sliding table 4
1 is fitted with a pair of upper and lower clamps 43 operated by a cylinder as is conventionally known. As shown in FIG.
8a and left and right frame portions 38b hanging from both left and right ends thereof.
and horizontal left and right placing parts 38c at the lower ends thereof, and the clamp sliding base 41 of the pull-out mechanism 37 is placed inside these, and the clamp 43 is placed in the missing part 38d between the left and right placing parts 38c. is now able to pass through. Upper frame portion 38a of this conveyance table 38
The central portion of the drawer screw 40 is connected to a sleeve 45 that is propelled by a carry-out screw 44 parallel to the pull-out screw 40, and the left and right frame portions 38b are guided by left and right conveyor rails 46. Air injection nozzles 47 that inject air toward each other inwardly are attached to the front ends of the left and right mounting portions 38c so that their positions can be adjusted. The rotation of the drawer/conveyance motor 39 is also transmitted to the unloading screw 44 via the transmission mechanism. In FIG. 9, lifting piece 36 is shown as above.
When the front end of sheet 8' is lifted by
After the clamp 43 is moved back by sliding of the clamp slide 41 and clamps the sheet 8a vertically by the operation of the cylinder, the clamp 43 immediately moves forward. During this time, the upper and lower cut parts 7a, 7 of the wamp 7
Since paper b continues to be sucked by the suction cups 31 and 29 with its mouth open, the sheet 8' is extracted from the wamp 7. During this extraction, the cut portion 7 on the lower side of the wamp 7
Since air is blown between the sheet 8a and the paper sheet 8a from the air injection needle 34 as described above, separation thereof, that is, extraction of the sheet 8' is performed smoothly. The extracted sheet 8' is placed on the left and right loading sections 38 of the conveyor table 38, which is waiting at a predetermined position.
It is mounted on c. When the clamp 43 advances to a predetermined position in the middle, the rotation of the drawer/conveyance motor 39 is also transmitted to the conveyance screw 44, and the conveyance table 38 advances at the same speed as the clamp 43, and the sheet 8
a is transported from the unsealing/transporting section 2 to the stacking/aligning section 3. Next, to explain this stacking/aligning section 3, there is a stacking table 48 for stacking sheets 8' by a chain 49, similar to the lift table 4 of the lifting/pushing section 1. suspended,
It is lifted and lowered in the same way. This stacking table 48 detects the stacking height of the sheets 8' stacked on it with a sensor, and the height of the stacked top surface is always constant. will be lowered by that amount. This height (when no sheets 8' are stacked, the height of the stacking table 48 itself) is the height of the stacking section 3 of the transport table 38.
It is slightly lower than 8c so that there is a difference in level. Further, a stopper 50 is rotatably mounted around a shaft 51 at the boundary between the loading/aligning section 3 and the unsealing/conveying section 2. The pivot position of this stopper 50 corresponds to the cutout 38d between the left and right placing parts 38c of the conveyance table 38. The stopper 50 is raised and lowered by a cylinder (not shown), and is normally laid down, but when raised, its free end becomes higher than the height of the mounting portion 38c. The stacking/aligning section 3 also includes a left/right aligning plate 52 that presses and aligns both left and right ends of sheets 8' newly stacked on the stacking table 48, and a stopper 50 that aligns the front edge.
A front alignment plate 53, which is pushed toward the front and aligned, is mounted so as to be slid along the guide rod by a cylinder. Further, at the top of the stacking/aligning section 3, left and right pushers 54 (Fig. 12) that push the left and right corners of the front end of the newly loaded top sheet 8' from above are movable vertically. It is installed vertically. These pushers 54 are moved up and down by cylinders. When the conveyance platform 38 carrying one stage of sheets 8' moves forward to a predetermined position above the loading table 48 as described above, the clamp 43 releases its clamping position, and as shown in FIG. stoppa 50
stands up. After that, the conveyance table 38 immediately retreats, but the rear end of the sheets 8' on it collides with the stopper 50 and the following retreat is restricted, so that the sheets 8' are already loaded on the loading table 48. It is unloaded directly onto the sheet 8' from the front end. Almost at the same time as the conveyance table 38 begins to move backward, the pusher 54 descends, and when only the front end of the sheet 8' has been unloaded, the pusher 54 presses the left and right corners of the sheet 8' from above. Immediately after the pressing starts, air is injected from the air injection nozzles 47 on both the left and right sides of the conveyance table 38, and air is blown onto the left and right side surfaces of the sheet 8' being unloaded from the conveyance table 38. At this time, the mounting section 38c of the conveyance table 38
is slightly higher than the top surface of the loading table 48, and there is a step between them, so the sheet 8' to be unloaded is bent by this step, and air is applied to the bent portions of the left and right sides. Since air is ejected from the insertion nozzle 47, air can be properly introduced between the sheets 8'. The bent part is the transport platform 3
As the sheet 8 moves backward, the air is inflated over the entire length of both left and right sides of the sheet 8'. When the conveyor table 38 retreats to the unpacking/conveying section 2,
After the pusher 54 is raised, the front alignment plate 53 is propelled to align the newly loaded sheet 8' with the sheet slightly below it, and the left and right alignment plates 52 are also propelled. These align the left and right positions. Thereafter, the stopper 50 is laid down, and the clamp 43 is also returned to the unsealing/conveying section 2 and retreated. While the sheet 8' is stacked as described above, the air injection needle 34 is
is retreated and the lower cut portion 7a of the lower part of the wamp 7
As the wamp 7 is pulled out from the suction cup 29, 3, the air injection stops and the empty wamp 7 is pulled out from the suction cup 29, 3.
1 is released, the upper opening body 30 returns downward and the lower opening body 21 returns upward. After this, the empty wamp 7 is discharged from the raising/pushing section 1 by the wamp discharging mechanism 10. Next, this wamp discharging mechanism 10 will be explained. As shown in FIGS. 4 and 5, the pushing body 18 for wrapped sheets (or the pushing body 1 for unwrapped sheets)
7) is further provided vertically with a suction cup 55 for returning the wamp so that it can be moved up and down by a cylinder 55a. Further, on the upper right side of the lifting/pushing part 1, as shown in FIG. Discharge suction cups 57 are vertically disposed at predetermined intervals in the front and rear. This sliding table 56 is also propelled left and right by the rotation of the motor. Furthermore, a lower wamp discharge drive roller 58 rotated by a motor is pivotally supported at the right end of the lifting/pushing part 1, and a cylinder 59
A driven roller 61 for discharging the wamp is pivotally supported by an arm 60 that is rotated by the arm 60 . When the arm 60 is rotated downward by the cylinder, the driven roller 61 comes into pressure contact with the driving roller 58 and rotates as a result of this. A wamp discharge guide plate 62 is installed slightly below the drive roller 58. The packaging sheet pushing body 18, which has pushed the packaging sheet 8 toward the unsealing/conveying section 2 as described above, moves forward until the empty wamp 7 is released from the suction cups 29, 31 as described above. Therefore, the pump return suction cup 55 is also in this position.
The wamp return suction cup 55 descends at this position and sucks the upper surface of the empty wamp 7, and then rises to lift the wamp 7 a little. Thereafter, the pushing body 18 retreats, and the empty wamp 7 is returned while being attracted to the return suction cup 55. When the pushing body 18 retreats to the original position and stops, the empty wamp 7 is attracted to the sucker 57 for discharging the wamp, and is released from the sucker 55 for returning the wamp, and the sliding base 56 for discharging the wamp slides to the right. By moving, it is sent between the wamp discharge drive roller 58 and the driven roller 61. This driven roller 6
When the wamp 1 is displaced downward and pressed against the drive roller 58, the empty wamp 7 is discharged to the right of the lifting/pushing section 1. When the discharge is completed, the lift table 4 is raised by one stage of the packaging sheets 8 loaded thereon, and then the above series of operations is repeated. On the other hand, in the case of unwrapped sheets 8a, a predetermined number of sheets at the top of the stack on the lift table 4 are separated and pushed by the unwrapped sheet pusher 17 as shown in FIG. It is advanced to above the lower opening body 21 which is horizontal. When the unwrapped sheet 8a is being advanced in this way, the left and right side cutters 23
And the front cutter 26 is retracted. When the unwrapped sheet 8a stops on the lower opening body 21, the clamp 43 moves the unwrapped sheet 8a at the recessed notch 21a (FIG. 10) provided at the center of the front side of the lower opening body 21. After pinching, the unwrapped sheet 8a is moved forward and placed on the left and right placing portions 38c of the conveyance table 38 in the same manner as described above. After this, the unwrapped sheet 8a is removed from the wamp 7 and the sheet 8'
As in the case of , the material is transported to the top of the loading table 48 by the transportation platform 38, and as the transportation platform 38 retreats, air is injected from both left and right sides from the air injection nozzle 47, and the material is loaded onto the loading table 48. Ru. Then, when the conveyor table 38, the clamp 43, and the pushing body 17 for unwrapped sheets move back and return, the lift table 4 is raised to a predetermined height, and then the series of operations is repeated.

【Effect of the invention】

As described above, the paper sorting device of the present invention has the following effects. A When pushing and separating the topmost packaged sheet or the topmost unwrapped sheet among the stacked packaging sheets, the wrapped or unwrapped sheet below it is removed. Air is continuously injected between the paper and the paper while it is being pushed, allowing for smooth separation. B While pushing as described above, the guide table is slid and transferred onto the conveyor table via this guide table, and at this time, the guide table is made hollow and air is injected from the inside of the top surface of the guide table. To inject air through the holes,
Together with the air injection from the rear end as described above,
Sheets can be pushed and separated even more smoothly, and can also be transferred to a conveyor table more smoothly. C: When unloading sheets from the conveyor table and stacking them again, air is injected from both left and right sides of the front end of the sheet while retracting the conveyor table, and air is injected from both left and right sides between the sheets. Since the paper is blown in and unloaded, the paper can be efficiently separated over the entire length of the paper on both the left and right sides.
