Abstract

PURPOSE:To automatically and efficiently carry out the work by man's labor by installing an air blowing-in mechanism onto a transport board in order to blow air into the side surfaces of the piled paper sheets. CONSTITUTION:Simultaneously with the start of retreat of a transport board 38, a pusher 54 lowers, and when no paper sheet 8' is unloaded from the front edge part, the right and left corner parts are pressed from the upper side by the pusher 54. Immediately after the start of pressing, air is jetted from the air nozzles 47 on the right and left sides of the transport board 38, and air is blown onto the right and left side surfaces of the paper sheet 8' unloaded from the transport board 38. The unloaded paper sheets 8' are bent by a step difference, and air is blown into the bent part on the right and left side surfaces from the air nozzle 47, and air blowing into the paper sheets 8' can be carried out smoothly. Since the bent part shifts rearward as the transport board 38 retreats, the air blowing is carried out over the whole length on the right and left side surfaces of the paper sheets 8'.

"Function" According to the device of the present invention, wrapped sheets or unwrapped sheets are stacked in multiple stages on a lift table, and the uppermost stage is pushed by a pushing mechanism while being blown with air to be unloaded. be done.

In the case of packaging sheets, the left and right sides of the packaging sheet are cut with a side cutter, and then the front side is cut with a front cutter that slides along the rail, and the opening is opened from the front edge by the upper and lower opening mechanisms. It will be opened. In this state, the sheets in the packaging sheet are held by clamps, extracted, and placed on a conveyance table.

On the other hand, in the case of unwrapped sheets, the sheets are held as they are with clamps, moved forward, and placed on a conveyance table.

Then, the sheets are conveyed onto the stacking table by the forward movement of the conveyance table, and stacked onto the stacking table by the backward movement of the conveyance table. At this time, air is introduced into the sheet from the side. The air inlet location moves along the side of the sheet as the conveyor moves backward.

"Example" An example of the present invention will be described below in detail with reference to the drawings.

The apparatus according to the present invention is roughly divided into a lifting/pushing section 1, an unsealing/conveying section 2, and a stacking/aligning section 3, as shown in Fig. 1.2.

A lift table 4 is suspended horizontally at its four corners by chains 5 on the lifting/pushing part 1.
is the sprocket wheel 6 that is meshing with the chain 5
When it is rotated by a motor, it is raised while remaining horizontal. Packaging sheets 8 wrapped in packaging sheets, for example, wamps 7 (FIG. 8), are loaded onto the lift table 4 by a forklift or the like while being stacked in multiple stages on a pallet. Even in the case of unwrapped sheets 8a (FIG. 7), they are loaded onto the lift table 4 while being stacked on the pallet.

The lifting/pushing section 1 also has a positioning mechanism on its upper part for positioning the uppermost packaging sheet 8 from side to side, and a positioning mechanism for pushing the positioned packaging sheet 8 toward the unsealing/conveying section 2. The pushing mechanism 9 that moves and the 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 that adjusts its position, a plurality of positioning pushing bodies 12 on the left side, and a positioning screw that propels it to the right. 13 and a positioning motor 13a that rotates the same, and a pushing body 12 pushes the left end of the uppermost packaging sheet 8, and the right end is moved to the ruler plate 11.
and position it.

The pushing mechanism 9 includes a pushing motor 9a as shown in FIG.
(FIGS. 1 and 2), a sliding plate 16 that is screwed onto the pushing screw 14 and slides back and forth along the guide rod 15 by the rotation of the pushing screw 14;
6 and a pair of pushing bodies 17 (FIG. 5) for unwrapped sheets. These pushing bodies 17 and 18 are detachable from the sliding plate 1G so that they can be replaced, and when the packaging sheets 8 are placed on the lift table 4, the pushing bodies 18 for packaging sheets are used. , when the unwrapped sheet 8a is loaded, the unwrapped sheet pushing body 7 is used.

As shown in FIGS. 4 and 6, the packaging sheet pusher 18 has a rod 18□ vertically slidably mounted on a mounting block 181, and a pusher 18 at the lower end of the rod 18□. This pusher 183 is urged downward by a spring 184 wound around the rod 18□. The front surface 18a of the pusher 183 is inclined backwardly, and a protrusion 18b is formed at the lower end of the inclination. In addition, the pusher 183 has an air nozzle 19 that injects air forward.
is attached, and air is supplied to the air nozzle 19 through a hose. This packaging sheet pushing body 18 is attached to its mounting block 18. is attached to the sliding plate 16 using bolts and nuts so as to be suspended therefrom.

The pushing body 17 for unwrapped sheets is attached to a mounting block 17. as shown in FIG. A rod 172 is vertically disposed vertically so as to be adjustable, and a pusher 173 is fixed to the lower end of the rod 17□. This pusher 173 has a U-shaped side surface, and a plurality of air injection holes 17 are provided at the front edge of the lower plate portion 17a.
(b) An air passage communicating with the air injection hole 17b is provided inside, and when air is supplied to this air passage through a hose, air is injected all at once from the air injection hole 17b.

-'I- When the packaging sheets 8 are stacked on the lift table 4 in multiple stages, the lift table 4 rises and the rear end of the packaging sheet 8 on the top tier is pushed into the packaging sheet pushing body. 18 pushers 18
When the uppermost surface of the packaging sheet 8 rises to a predetermined position, this is detected by the sensor, and the lifting operation of the lift table 4 is stopped. Stop. 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, the pusher 183 has a front surface 18a inclined as described above, and a spring 18a.
Since the pusher 183 is urged downward by the pusher 4, even if the position of the rear end of the uppermost packaging sheet 8 is slightly shifted when it stops, or even if the thickness is different, the pusher 183 When moving forward, the protrusion 18b and the rear end of the packaging sheet 8 are accurately engaged, and 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 surface of the stack of 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 portion 17a of the pusher 173 A state in which a predetermined number of unwrapped sheets 8a are inserted into the rear end of the stacked upper end of the paper 8a, and a predetermined number of unwrapped sheets 8a above the insertion portion are held at their rear ends by a pusher 173 as shown in FIG. This pushes it forward.

At this time, air is being injected from the air injection hole 17b at the front end edge of the lower plate portion 17a of the pusher 173.
The lower plate part 17a smoothly enters the upper end of the stack of unwrapped sheets 8a, and the predetermined number of unwrapped sheets 8a, whose rear ends are held by the pushers 173, are placed under (Q+l).
The unwrapped sheets 8a are smoothly separated and advanced.

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, which has been pushed forward by the packaging sheet pusher 18 as described above, slides on the horizontal guide table 20 and reaches a horizontal state as shown in FIG. The user rides on the horizontally elongated lower opening plate 21, and stops when the front end collides with a front opening position stopper 22 (see FIG. 10) protruding from the tip of the lower opening plate 21. As shown in FIG. 8, the indoor table 20 is hollow and has a large number of air injection holes 20a on its upper surface and curved rear end surface, and the packaging sheet 8 is air-filled through the air injection holes 20a. Since it is sprayed, it slides smoothly on the guide table 20.

Then, while the packaging sheet 8 is moving forward until it collides with the front opening position stopper 22, the horizontally rotating disc-shaped left and right side cutters 23 automatically cut the left and right sides of the wamp 7 as it moves forward. disconnected. These side cutters 23 are individually rotated by a cutter motor 24, and their positions do not move back and forth, but they are pushed left and right by a mechanism 24a.
At the same time, the opening can be adjusted and the opening can be evacuated to a non-active position (right end or left end).

The packaging sheet 8, whose front end is positioned by the front opening position stopper 22, is rotated horizontally and moved to the canterail 25.
The entire length of the front surface of the wamp 7 is cut by a disk-shaped front cutter 26 that slides leftward or rightward along the wamp 7. A cutter motor 27 that rotates the front cutter 26 is attached to a cutter slide 28 mounted on the cutter rail 25, and the cutter slide 28 is slid by, for example, a chain drive. The front cutter 26 can also be retracted to an inactive position (right end or left end) where it does not perform the opening operation.

When the front ends of the right and left sides and the entire front length of the wamp 7 are cut in this way, the plurality of lower suction cups 29 attached to the lower opening plate 21 and the plurality of upper suction cups attached to the upper opening plate 30 are cut. Air suction by the suction cups 31 starts, and the lower and upper surfaces of the wamp 7 are attracted to the upper surface of the lower opening plate 21 and the upper suction cup 3I by suction by these suction cups 29 and 31. The lower suction cup 29 is attached to the lower side of the lower opening plate 21 and faces the suction hole 32 as shown in FIG. The upper suction cup 31 is provided to protrude from the lower surface of the upper opening plate 30.

The lower opening vi21 has both left and right ends pivoted on a shaft 33,
It is rotated up and down by a motor or cylinder (not shown), and the upper opening plate 30 is rotated up and down by the cylinder. Air injection needles 34 are mounted at a plurality of left and right locations on the lower side of the lower opening plate 21 so as to be movable forward and backward by an injection needle operating cylinder 34a, and air is injected from these.

When the wamp 7 is attracted as described above, the lower opening plate 21 rotates downward as shown by the chain line in FIG. 8, and the upper opening plate 30 rotates upward, so that the front end has already been cut. The wamp 7 has cut parts 7a above and below the cut line.
, 7b, which are opened by turning both upward and downward, and the front end is opened, and the front end of the sheet 8' inside the wamp 7 is exposed. At this time, the injection needle operating cylinder 34a is activated and the air injection needle 34 is moved to the lower opening plate 2.
It protrudes forward from the small hole 1, pierces the cut portion 7b on the lower side of the wamp 7 at multiple places on the right and left from the rear side, and injects air toward the front. Further, as the lower opening plate 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 lifted up to a horizontal state by the L-shaped lifting piece 36 of the lifting mechanism 35. At this time, since air is being injected from the air injection needle 34 as described above, even if the front edge of some of the lower sheets 8' is cracked, it is not caused by air. The jet pushes up and lifts it all 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', which has been lifted by its front end, is pulled forward from the wamp 7 by the pull-out mechanism 37 as follows, and placed on a gondola-like conveyance table 38'2.

The pull-out mechanism 37 transmits the rotation of the pull-out/conveyance motor 39 to the pull-out screw 40 via the transmission mfM, and the rotation of the screw 40 causes the clamp sliding base 41 to be moved onto the clamp rail 42 (FIG. 11). Slide it back and forth. A pair of upper and lower clamps 43 operated by cylinders are mounted on this clamp sliding table 41 as is conventionally known.

As shown in FIG. 11, the conveyance table 38 consists of an upper frame portion 38a, left and right frame portions 38b hanging down from both left and right ends of the upper frame portion 38a, and horizontal left and right mounting portions 38c at the lower ends of the upper frame portion 38a. The clamp sliding base 41 of No. 37 is also mounted on the clamp 43 in the missing portion 38d between the left and right mounting portions 38c.
can pass through. The center portions of the two frame portions 38a of the conveyor table 38 are connected to a sleeve 45 propelled by a carry-out screw 44 parallel to the pull-out screw 40, and the left and right frame portions 38b are connected to the left and right conveyor rails 46. You will be guided. The left and right placing parts 38c
Air inlet nozzles 47 that inject air inwardly are attached to the front ends of the nozzles 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, when the front end of the sheet 8' is lifted by the lifting piece 36 as described above, the clamp 43
is moved backward by the sliding of the clamp sliding table 41, and after the sheet 8a is clamped vertically by the operation of the cylinder, the clamp 43 immediately moves forward. During this time, the upper and lower cut portions 7a, 7b of the wamp 7 are continuously sucked by the suction cups 31, 29 with their mouths open, so that the sheet 8' is extracted from the wamp 7. During this extraction, the air injection needle 34 is inserted between the cut portion 7h on the lower side of the wamp 7 and the sheet 8a as described above.
Since more air is blown in, these separations, that is, the ejection of the sheets 8', are carried out smoothly. The extracted sheet 8' is placed on the left and right RR sections 38c of the conveyance table 38, which are waiting at a predetermined position.

When the clamp 43 advances to a predetermined position midway, the rotation of the drawer/conveyance motor 39 is also transmitted to the forwarding screw 44, and the conveyance platform 38 advances at the same speed as the clamp 43.
Sheets 8a are 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'.
It is supported by the chain 49 in the same way as the lift table 4 of the lifting/pushing section 1, and is raised and lowered in the same manner. 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 tall sheet of paper 8'
When no paper is loaded, the height of the stacking table 48 itself is slightly lower than the height of the stacking table 48 so as to create a step between it and the loading section 38c of the transport platform 38.

In addition, at the boundary between the loading/aligning section 3 and the unpacking/conveying section 2,
A stopper 50 is rotatably mounted around a shaft 51. The pivot position of this stopper 50 corresponds to the missing portion 38d between the left and right placing portions 38c of the conveyance platform 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 loading/preparing section 3 also includes a left-right aligning plate 52 for pressing and aligning both left and right ends of sheets 8' newly stacked on the loading table 48, and a front aligning plate 53 for aligning the sheets 8' by pushing the front ends toward the stopper 50. are each mounted so as to be slid along the guide rod by a cylinder. Further, at the top of the stacking/aligning section 3, there are left and right pushers 54 (12th) that push the left and right corners of the front end of the newly stacked top sheet 8' from above, and are movable up and down. It is installed vertically. These buttons 54 are moved up and down by cylinders.

As mentioned above, the conveyance table 38 carries one stage of sheets 8'.
advances to a predetermined position above the loading table 48,
When the clamp 43 releases its grip, the stopper 50 stands up as shown in the 12th episode.

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 right and left 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' to be unloaded from the conveyance table 3. At this time, the mounting section 38c of the conveyance table 38
The height is slightly higher than the top surface of the loading table 48,
Since there is a level difference between these, the sheet 8' to be unloaded is bent by this level difference, and air is injected from the air nozzle 47 to the bent part on the left and right sides, so that the sheet 8' is unloaded. The air is injected well.

Since the bent portion moves rearward as the conveyance table 38 moves backward, air is injected 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, the pusher 54 rises, and the front alignment plate 53 is propelled to move the newly loaded sheet 8' along with the sheet slightly below it to the front and rear positions. are aligned, and the left and right alignment plates 52 are pushed to align the left and right positions. After this, stopper 50
is laid down, and the clamp 43 also returns to the unsealing/conveying section 2 and retreats.

While the sheet 8' is being stacked as described above,
In the unsealing/conveying section 2, the air injection needle 34 retreats and is pulled out from the lower cut portion 7a of the lower part of the wamp 7, and the air injection thereby stops, and the empty wamp 7 is replaced with a suction cup. The suction by 29.31 is released, and the upper opening plate 30 returns downward and the lower opening plate 21 returns upward.

After this, the empty wamp 7 is discharged by the wamp discharge mechanism 10 in the lifting/pushing section 1. Next, this wamp discharge mechanism 10 will be explained.

As shown in Figures 4 and 5, the sliding plate 16 on which the pushing body 18 for wrapped sheets (or the pushing body 17 for unwrapped sheets) is mounted also has a pusher for returning the wamp. A suction cup 55 is provided vertically so as to be movable 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 an arm 60 rotated by a cylinder 59.
A driven roller 61 for discharging the wamp is pivotally supported. 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 cup 29, 31 as described above. Therefore, the wamp return suction cup 55 remains in the stopped position.
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. When this driven roller 61 is displaced downward and pressed against the driving roller 58, the empty wamp 7 rises.
It is discharged to the right of the pushing part l.

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 sheet paper 8a, the lift table 4
As shown in FIG. 7, a predetermined number of the upper stacked sheets are separated and pushed by the pusher 17 for unwrapped sheets, and advanced to the lower opening plate 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 are retracted.

When the unwrapped sheet 8a stops at the lower opening plate 21'',
After the clamp 43 clamps the unwrapped sheet 8a at the recessed notch 21a (FIG. 10) provided at the center of the front side of the lower opening plate 21, it moves forward and unwraps the unwrapped sheet 8a as described above. Similarly, it is placed on the left and right placing portions 38c of the conveyance table 38.

Thereafter, the unwrapped sheet 8a is conveyed by the conveyance table 38 to the top of the loading table 48, in the same way as the sheet 8' extracted from the wamp 7. Accordingly, air is introduced from both the left and right sides from the air nozzle 47, and the products are loaded on the loading table 48. Then,
Conveyance platform 38, clamp 43, and pushing body 1 for unwrapped sheets
When the lift table 7 moves back and returns, the lift table 4 is raised to a predetermined height, and then the series of operations is repeated.

``Effects of the Invention'' As described below, according to the apparatus of the present invention, wrapped sheets and unwrapped sheets can be handled in the same manner with a single device.

In the case of packaging sheets, the left and right sides of the packaging sheets are automatically cut while the packaging sheets are stacked in multiple stages and are advanced one stage at a time, as if unloading.
Also, after stopping its advance and automatically cutting the front side, the packaging sear! Since the paper is opened by suctioning the paper and the sheet inside is extracted in that state, the paper can be extracted efficiently. moreover,
At the same time as the sheet is extracted, it is placed on the conveyor, and after the first general feeder is advanced to the stacking position, it is moved backward and stacked while unloading the sheet, and at this time, air is blown into the side of the sheet. Therefore, loading and air handling can be carried out efficiently, and the same is true for unwrapped sheets.
