Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a state in which, in a machine using a web such as an offset rotary press, when the web is sequentially fed and spliced, it can be conveniently inherited by the preceding paper. The present invention relates to an automatic trimming device for trimming the edge of a web of paper that is a subsequent paper.

(Prior art) There is no device that automatically prepares paper rolls, and it usually takes 2 to 3
At present, one or more workers manually prepare the paper rolls.

Therefore, the outline and necessity of this paper roll production work will be explained below.

In machines that use paper rolls, such as newspaper rotary presses, offset rotary presses, coating machines, and corrugated machines that produce corrugated paperboard sheets, it is necessary to sequentially feed (splice) the roll paper (coiled paper).

In order to carry out the paper splicing, it is necessary to form a g-end (paper splicing part) in advance and tailor the web paper so that it can be properly inherited by the preceding paper.

The paper rolls are packed and transported from paper storage etc. to the paper feeding section of the above-mentioned printing or production line, but during the transportation process after the paper rolls are manufactured, the ends of the rolls may become loose, droop, shift, wrinkle, scratch, etc. occurs. Therefore, the worker removed about 5 to 10 rolls of unusable paper on the floor using a paper towel, a bamboo spatula, a knife, etc., depending on the state of damage, and replaced the paper edge (paper splicing part) with the preceding paper. To make it easier to fit, cut it into a V-shape, secure the tip with a paper presser tab, and then apply glue with a brush or stick double-sided adhesive tape to the V-shaped paper edge on the outer circumferential side. This is all done by hand, and the tailoring work is done in preparation for paper splicing.

The paper rolls prepared in this manner are transported by a trolley to a predetermined position in an automatic paper splicing device such as a rotary press, and then automatically installed and automatically spliced.

As described above, in rotary presses, automatic splicing devices, automatic roll paper mounting devices, and other parts have been automated in the past, but the winding paper sewing operation is difficult to automate.
It was not automated, and the biggest challenge was how to automate it.

Therefore, currently, workers are forced to perform tailoring work manually at individual locations, and even if other locations were automated, it was not possible to significantly reduce the number of machine workers.

(Problems to be Solved by the Invention) The present invention requires the conventional paper roll making work to be carried out manually, making it impossible to reduce the number of machine workers, resulting in high lining costs, and further improving operability. This was done in order to solve problems such as difficulty in using the machine, and aims to reduce the number of workers and costs by automating the above-mentioned work.

(Means for Solving the Problems) For this reason, the present invention provides two or more pairs of chuck arms that are rotated by a main shaft and are slidable in the axial direction on the main shaft, and are mounted on a cart via an appropriate chucking means. a roll paper loading device for loading a roll of paper; an eccentric cutter device for cutting the surface paper and discharging the cut paper; a good paper feeding device for feeding good paper to a workbench; and a workbench for supporting the leading edge of good paper. ,
A means for solving the above-mentioned problems is provided by a tailoring device that performs tailoring operations such as pasting adhesive tape, cutting paper, pasting tabs, and cutting on the workbench.

(Function) In the device configured as described above, the web attached to the chuck arm is cut by an eccentric cutter, which consists of an eccentric mechanism attached toward the center of the web at the cutting position, and whose blade width is adjustable. , the surface paper and unusable paper are cut, and the defective paper is discharged by the surface paper conveyor through rotation of winding and feeding of the web.

After that, the good paper is sent out onto the workbench via the delivery belt by jet air blowing from the air tube, the edge of the paper is adsorbed with suction, and the automatic adhesive tape pasting device is used to apply double-sided paper in a 7-shape shape, for example. Apply adhesive tape and cut into a V-shape along the adhesive tape using an automatic traveling cutter.

After the V-shaped cutting is completed, a tab is attached to the tip of the tailored portion using a tab attaching device with a cutter, and the tip is cut. Subsequently, the edge of the paper is wound up, and the tab at the leading end of the paper roll adheres to the surface of the paper roll, thereby completing automatic tailoring.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

The drawings all show embodiments of the present invention, and FIG. 1 is an overall view of the automatic tailoring device, FIG. 2 is a view taken along the line X-X of the web loading device, FIG. The figure shows a schematic perspective view of the workbench, FIG. 5 shows a side view of the automatic adhesive tape application device, and FIG. 6 shows a perspective view of the same device.

A pedestal 1 for holding the entire automatic tailoring apparatus is erected on the floor surface, and a main shaft 3 connected to a main shaft driving device (not shown) via a bearing 2 is attached to the pedestal 1. Two or more pairs of symmetrically formed chuck arms 4 are attached to the main shaft 3 via a rack 5 and a pinion 6, and the pinion 6 is engaged with the rack 5 by a drive device 7.
When the chuck arm 4 rotates at the same circumferential speed in the opposite direction, the chuck arm 4 becomes
The outer peripheral surface of the main shaft 3 can be slidably moved according to the paper width of the web 8.

Note that this embodiment illustrates a case where there are three pairs of chuck arms as an example.

A core chuck 9 is also mounted near the tip of the chuck arm 4 via a rank 1o and a pinion 11, and a drive device 12 rotates the pinion 11 meshing with the rack 10 in the opposite direction to remove the web. 8 can be attached and detached, and the core chuck 9 on one side is connected to the chuck drive motor 13.
The roll paper 8 can be rotated.

On the other hand, a guide rail 14 is rotatably held between frames (not shown) parallel to the main shaft 3 and on the opposite side of the carriage 53 with the gantry 1 in between. A head cylinder 15 is attached to the guide rail 14, and the tip of the cylinder rod is, for example,
An eccentric cutter 16 as shown in Japanese Patent No. 9803 is attached so as to face the center of the web 8. This eccentric cutter 16 adopts an eccentric shaft mechanism so that the number of sheets to be cut can be adjusted, and the width of the crest of the cutter 17 can be finely adjusted. Cut the unrolled surface paper. The cutter 17 is a disc-shaped rotary type.

The eccentric cutter 16 runs along the guide rail 14 in the width direction of the web 8 by a traveling cylinder (not shown) to cut the defective paper on the surface layer of the web 8, and also rotates around the guide rail 14, It is possible to cut one sheet of good paper at the position indicated by the chain line in the figure.

A pair of surface paper conveyors 18a and 18 are provided below the eccentric cutter 16 for sandwiching and discharging the cut defective paper.
A delivery belt 19 for delivering one sheet of good paper to the workbench 20 is installed above the eccentric cutter 16 so as to be rotated in one direction by a drive device 52. Further, the delivery belt 19 can be moved from a standby position shown by a solid line to a working position shown by a dashed-dotted line by an appropriate means (not shown).

An air pipe 21 is provided between the delivery belt 19 and the eccentric cutter 16, which has a large number of nozzle holes oriented in a predetermined direction and can be rotated from a standby position to a large diameter position of the web and to the same (small diameter position). Jet air from each setting position of the air pipe 21 blows one sheet of good paper onto the lower surface of the transfer belt 19 in the working position, and the roll paper 8 is moved by the operation of the transfer belt 19 and the rotation of the core chuck 90. By rotating in the direction of arrow A, the end of the paper is sent out to the workbench 20.

There is a V-shaped groove 2 on the top surface of the workbench 20 shown in FIGS. 3 and 4.
3, and a large number of suction holes 24 are drilled around the working table 20. A pair of tension rolls 25 are provided near the lower end of the working table 20 for feeding and nipping the paper.

Further, above the workbench 20, a V-shaped frame 2G is provided parallel to the workbench 20 with a predetermined interval, and the frame 26 is provided with a automatic adhesive tape pasting device 27 and cutter 2
A plurality of rails 29 for 8 are provided in rows.

To briefly explain the automatic adhesive tape applicator 27 with reference to FIGS. 5 and 6, the tape applicator 30 is applied via a header 48 in which a concave member 31 is fitted into a rail 29 with inclined grooves cut on both sides. The tape applicator 30 moves up and down as shown by the dashed line through the arm 33 as the cylinder 32 expands and contracts, and when applying the tape,
The press provided at the lower end of the tape applicator 30 is such that the rolls 34,35 abut against the workbench 2o.

The double-sided adhesive tape 36 and the adhesive tape release paper 37 are attached to an adhesive tape spool mounting machine 38, and are fed out and the release paper is wound up.

Here, the roll 34 presses the rubber-like material that is in contact with the workbench 20 via the web 8, and rotates with the movement of the automatic adhesive tape applicator 27, which is moved by a drive device such as a traveling cylinder, and the tape applicator The O-ring belt 39 is suspended between a pulley (not shown) fixed to one shaft end protruding from the back side of the 0-ring belt 30 and a bobbin also fixed to one shaft end of the peeling abrasive spool mounting machine 38'. The release paper spool mounting machine 38' is also rotated through the release paper spool mounting machine 38'. Therefore, the release paper 37 is pressed and wound up by the rotation of the roll 34.

However, as shown by the one-dot chain line, as the release paper becomes thicker and its diameter changes, the above pressing is caused by the pulley of the roll 34.
It is necessary to change the rotation speed of the release paper spool,
Since the O-ring belt 39 slips, there is no need to control the rotational speed of the release paper spool mounting device 38' again.

Next, the double-sided adhesive tape spool mounting machine 38 is fed out, and the two presses are inverted T-shaped near the rolls 34 and 35.
A roll holder 40 having a shape of 40 is provided, and presser rolls 41 and 42 are held at both ends of the roll holder. Both presser rolls 41, 42 can be swung by actuation of the cylinder 43 to which they are attached.

Here, when the rod of the cylinder 43 is extended, the presser roll 41 is at the position 41' shown in the figure, and at this time, the double-sided adhesive tape 36 that is passed between the rolls is pasted onto the web 8. When cutting the double-sided adhesive tape 36 at a predetermined position, retract the cylinder rod and press the presser roll 41.
When it is returned to its original position, only the release adhesive tape 44 remains in the gap between the paper roll 8 and the roll.

A tape cutting knife 46 attached to the rod of the cylinder 45 is moved forward into the gap to cut the tape.

Reference numeral 47 indicates a cutting line of the paper by the paper cutting cutter 28.

A cutter 28 that runs and cuts along the ■-shaped groove 23 of the workbench 20 is provided above the workbench 20, and also cuts the V-shaped groove 23.
A horizontal groove intersecting with the ■-shaped groove 23 is cut out at the tip of the tip, and a tip tab pasting device 50 having another cutter 49 runs in the horizontal direction, and the cutter 28 cuts the tip into a ■-shape. Tab 5 on the back side of the paper that has been cut into a V shape.
After pasting 1, the tip is cut off.

The remaining paper after cutting is discharged to the waste paper collection vehicle 55 by 250 rotations of the tension roll.0 It takes some time to do the sewing work on the workbench 20, so in order to shorten the time even slightly, we The delivery belt 19 in the position is
The paper roll 8 slides to the standby position, and while the core chuck 9 rotates to feed out the paper, the main shaft 3 rotates to move from the cover stripping and sewing position 22b to the sewing position 22c, and the work is completed. Jet air is ejected from the air pipe 56 to minimize paper blurring up to the top of the table 20.
I'm trying to make the paper blow up.

When the sewing work on the workbench 20 is finished, the paper is wound up in the direction of arrow B by rotation of the core chuck 9 at the sewing position 22c, and at this time, the tab 51 at the tip is stuck to the web 8 by the presser roll 57. Ru. In this way, the plurality of chuck arms 4 are rotated by the rotation of the main shaft 3 to the rfIi lowering position 22a, the cover stripping and sewing position 22bJ r sewing position 22c, and the roll paper is sequentially loaded and the transition is repeated. Automatic tailoring operation is performed.

The paper roll 8 shown by the dashed dotted line has a small diameter, and a lift 54 is provided under the floor below the chuck arm loading/unloading position 22a.

It should be noted that the present invention is not limited only to the above embodiments,
Various changes may be made without departing from the spirit of the invention. For example, the paper edge trimming shape does not necessarily have to be V-shaped (it can be cut into any desired shape).

In the apparatus configured as described above, the operation thereof will be described. The paper roll 8 is carried by a cart 53, and is moved together with the cart 53 by a lift 54 to the chuck arm "unloading position 22a".
will be raised to

The device of the first web 8 has two symmetrically formed devices.
(Two or more chuck arms 4 are simultaneously slid to a predetermined position by rotation of a pinion 6 in the chuck arm 4 that is engaged with a rack 5 provided on the main shaft 3, depending on the paper width detected by the phototube.) The core chuck 9, which is in the FA position, is inserted into the core and takes the landing position by the above-described rank 10 and bin 1 f 11 mechanisms, and catches the web 8.

The chuck arm 4 to which the web 8 is attached is connected to the main idr 3
The rotation stops at the cover stripping/sewing position 22bJ.At this time, the delivery belt 19, which had been moved to the standby position to avoid interference with the device roll 8, is slid to the working position, and the presser roll The roll 8 is held down by the roll at the tip end, and then the eccentric cutter 16, which is adjusted to cut about 5 sheets of defective paper on the surface of the roll, is brought into contact with the roll 8 by extending the rod of the cylinder 15.
The travel cylinder is driven to run and cut, and the mouth and rad are contracted and returned to their original positions.

The cut defective paper falls and hangs on the opposite side of the paper roll 8 as indicated by the dotted line arrow, since the top roller of the delivery belt 19 presses the top of the paper roll 8. Here, when the web 8 is rotated in the direction of the arrow by rotating the corer handle 9, the poorly cut paper is rolled up and lowered to the opposite side, where it is sandwiched between the pair of surface paper conveyors 183° 18b. The paper is then conveyed and discharged to the waste paper collection vehicle 55. At this time, the leading edge of one good sheet of paper that has followed the bottom layer of the overlapping cut surface sheets is conveyed to cover conveyors a, b,
When the paper is stretched between 18a and 18b, the surface paper conveyor 18a.

The drive of the eccentric cutter 18b is stopped, and the guide rail 14 on which the eccentric cutter 16 is mounted is rotated to bring the eccentric cutter 16 to the chain line position, and the eccentric cutter 16 is moved and returned to cut one sheet of good paper.

The eccentric cutter 16 returns to its original position, the cut good paper is discharged by cover conveyors 18a and 18b, the web 8 is rotated approximately 90 degrees in the direction of arrow B by the rotation of the core chuck 9, and then stopped, and the attached web is removed. The air tube 21, which had been moved to the standby position to avoid being in the same phase as 8, is rotated from the ``standby position'' to the ``roll paper, large diameter position'', and the jet air is transferred from the nozzle to 1 on the side of the roll 8. When the paper is ejected to the width of the cut paper, the paper is sprayed onto the lower surface of the delivery belt 19 in the working position, and as the core chuck 90 rotates and the paper roll 8 rotates in the direction of arrow A and the delivery belt 19 runs,
A sheet of good paper is sent to the workbench 20, slides down the slope of the workbench 20, and the edge of the paper is held between the tension rolls 25 and stretched. At the same time, the scratch detector 58
Detects scratches on paper.

The good paper on the workbench 20 receives suction from the suction hole 24, and the edges of the paper are trimmed as described below. First, the automatic adhesive tape applicator 27 applies the release adhesive tape 44 in a V-shape as described above, returns it to the original position and waits, and then the cutter 28 uses the traveling cylinder to cut the outside of the adhesive tape 44 as shown in FIG. It is cut along the cuckoo cutting line 47 shown in FIG.

Note that the application of the adhesive tape and the cutting and folding using the cutter 28 may be performed simultaneously by means such as providing a cutter in conjunction with the tape applicator 30.

After cutting into a V-shape leaving the tip, the tip tab pasting device 50 having another cutter 49 runs horizontally over the cutting groove, and after pasting the tab 51 on the back side of the V-shaped tip, the tip disconnect and return. This completes each operation on the upper surface of the workbench 20, and the remaining paper after cutting is discharged to the waste paper collection vehicle 55 by the rotation of the tension roll 25.

As mentioned above, the sewing work on the workbench 20 takes some time, so during that time the delivery belt 19 in the working position
slides to the standby position, and the web 8 is fed out by the rotation of the core chuck 9, and at the same time, by the rotation of the main shaft 3, it is moved from the ``cover peeling and sewing position 22b'' to the ``tailoring position 22C.'' Moving. When the sewing work on the workbench 20 is finished, the core chuck 9 rotates, and the paper enters between the presser roll 57 and the workbench 20 and is rolled up by the air from the air pipe 56. At this time, the tip tab 51 is stuck to the web 8 by a presser roll 57 coated with silicon to prevent the release adhesive tape 44 from sticking when passing through the roll section.

The core chuck drive device, whose rotation is controlled by a phase angle detector such as a rotary encoder, is positioned at a predetermined position so that the adhesive tape attached to the cover of the paper roll 8 does not come off from the upper surface of the cart 53. Stop, then spindle 3
The core chuck 9 is then removed from the core by the operation of the rack 10 and bini-off 11 mechanism and placed in the unloading position. , remove the tailoring web 8.

When the removal of the tailored web is completed, the lift 54 is lowered, the cart 53 is moved outside the apparatus, and the next web 8 that has been waiting outside is carried in and loaded. These operations are performed in sequence and automatically controlled.

(Effects of the Invention) As described in detail above, according to the present invention, in addition to automating the conventional automatic paper splicing device and automatic roll paper attachment in rotary presses, etc., the tailoring of the roll paper is automated. This made it possible to significantly reduce the number of aircraft personnel.

In addition, in the present invention, in particular, a series of tailoring operations are carried out by multiple chuck arm companies, such as mounting work from a trolley, return to the trolley,
The work is divided into unloading work, surface paper cutting, delivery work to the workbench, tailoring work, etc., and is carried out sequentially, making it possible to further speed up the work and shorten the tailoring work time, as well as improve the quality of tailoring. Product yield can be improved due to stability.

Furthermore, since the "automatic roll paper tailoring device" according to the present invention can be installed at one desired location, such as near the paper warehouse, automatic tailoring can be carried out in a centralized manner, and this can be transported to several rotary presses, etc., resulting in significantly improved This makes it possible to save labor and significantly reduce costs.

Since automatic tailoring can be performed in one place in this way, it is easier to dispose of waste paper, improve environmental friendliness, and improve the factory layout.
Coating machines, corrugating machines, etc. can be used in a wide range of applications, and their synergistic effects are also large.
