Description

[0001]
[Industrial application fields]
The present invention is a roll that removes the outer skin including the packing material on the outer peripheral surface of a roll paper used for a rotary printing machine, a coater, and the like, and performs tailoring for paper splicing on the front end of the roll paper after the skin removal. The present invention relates to a paper unpacking tailoring apparatus. The term “paper” used in this specification is not limited to paper of a strict meaning, but also includes films, sheets, and the like.
[0002]
[Prior art]
In general, roll paper used in a rotary printing press is transported in a state in which a peripheral surface and an end surface are covered with a packaging material such as craft paper, paperboard, and a vinyl chloride resin sheet. In order to apply the packaged roll paper to a rotary printing machine, first, the packaging material on both end portions of the roll paper is removed, then the packaging material on the peripheral surface portion is removed, and then the main sheet of the surface layer is removed from the roll paper. Unrolling and removing defective parts, then cutting the leading edge of the paper into a suitable shape (for example, V-shaped) to form the paper edge, and sticking double-sided tape to the paper edge A layer is formed, and then the end of the paper is rewound onto the roll paper, and the paper is tailored on the surface of the roll paper using a loosening prevention tab. This operation was usually done manually.
[0003]
However, these operations are heavy labor, and automation and mechanization have been desired. Therefore, an apparatus in which some of these operations are automated is known. For example, for tailoring, the roll paper after removing the packing material is rotatably held by a chucking arm, the surface layer portion of the roll paper is cut in the axial direction, the roll paper is rotated, and the cut surface layer is cut The paper on the roll paper is fed out onto the table, and the defective part of the surface layer passes through the table and is discharged into the waste box. Then, the front end of the roll paper fed to the table is cut into a predetermined shape, and double-sided tape is attached to the front end. Have been developed (for example, “Newsprint Technology” 1987-I, NO119, page 12). To page 15, page 16 to page 18, etc.).
[0004]
In addition, as a device that automates the removal of the packing material on the outer peripheral surface and the tailoring operation, the roll paper after removing only the end face packing material is held rotatably by the chucking arm, and the packing material and surface layer of the roll paper are defective. Cut the skin including the main paper in the axial direction of the roll paper, rotate the roll paper, feed the cut skin onto the table, and pass it over the table to the waste box, and then send it to the table. Developed a device that cuts the leading edge of the rolled paper side into a predetermined shape, attaches double-sided tape to the leading edge, attaches a loosening prevention tab, and then rewinds the leading edge of the paper on the roll paper. (See, for example, JP-A-4-44940).
[0005]
[Problems to be solved by the invention]
However, in an apparatus that automates only the tailoring operation, the packaging material on the outer peripheral surface of the roll paper has to be removed manually, and there is a problem that the work load on the operator is heavy. On the other hand, in the apparatus disclosed in Japanese Patent Laid-Open No. 4-44940, the packing material removal and tailoring operation on the outer peripheral surface of the roll paper are automated, so the work load is reduced, but the skin is cut, removed, and tailored. Since it is carried out at the same position, there is a problem that the tailoring cannot be performed until the skin is cut and removed, resulting in poor productivity.
[0006]
In order to solve this problem, a roll paper unpacking device for removing the packing material and a tailoring device for tailoring may be provided separately, and the packing material removing operation and the tailoring operation may be performed in parallel. As the roll paper unpacking device for removing the packing material, it is considered that the portion for performing the tailoring operation from the device disclosed in Japanese Patent Laid-Open No. 4-44940 described above may be eliminated. However, in the roll paper unpacking apparatus configured as described above, the cut skin is fed from the upper end of the roll paper by rotating the roll paper, and the feed direction is the direction to feed out the roll paper under the skin. For this reason, even after finishing the feeding of the skin, the leading edge of the paper that was under the skin is continuously fed out, and the paper must be cut at an appropriate timing, requiring extra operations and time. The problem that it took.
[0007]
Also, when setting the roll paper that should be removed from the packing material into the roll paper unpacking device, it is necessary to check the roll paper winding direction and set it in the correct direction. There is no way to do this, it is based on visual confirmation by the worker, and the roll paper is manually rotated 180 degrees to change the winding direction. It was.
[0008]
The present invention has been made in view of such conventional problems, and can perform unpacking and tailoring with high efficiency by performing unrolling operation and tailoring operation of roll paper in parallel. It is an object of the present invention to provide a roll paper unpacking tailoring device that can unpack and tailor without any trouble even if the paper winding direction is set incorrectly.
[0009]
[Means for Solving the Problems]
The present invention, which has been made to achieve the above object, is provided at an unpacking position for unpacking roll paper, and removes the skin including the packing material on the peripheral surface of the roll paper, and the unpacking position, Is provided at another tailoring position, and includes a tailoring device for performing a predetermined tailoring on the roll paper after removing the skin, and a roll paper transporting means for transporting the roll paper from the unpacking position to the tailoring position. A package tailoring device, wherein the skin removing device cuts the skin of the roll paper in the axial direction of the roll paper, and the roll paper so as to send out the skin cut from the lower side of the roll paper. From the roll paper holding and rotating device that holds and rotates, the transport device that transports the skin sent out from the roll paper, and the roll paper After the rear end of the delivered skin has passed a predetermined position on the transport device Roll paper From This paper is on the transport device At the predetermined position Rolled out Is A paper detection means for detecting whether or not the paper is fed from the roll paper. ing A paper cutting device for cutting the paper based on a paper detection signal from the paper detection means, and the roll paper conveying means is configured to open the paper based on the paper detection signal from the paper detection means. Turn the roll paper taken out of the packing position 180 degrees Reverse the winding direction The gist of the roll paper unpacking tailoring apparatus is characterized in that it is configured to be conveyed to a tailoring position.
[0010]
Here, the book paper detection means is configured to detect the skin and the paper transported on the transport device, and after the elapse of time required for the trailing edge of the skin sent out from the roll paper to pass through the light sensor, It is preferable to include a determination unit that checks a signal from the optical sensor and determines whether or not the paper is fed out.
[0011]
Moreover, it is preferable that the said roll paper conveyance means is set as the structure provided with the turntable arrange | positioned between the said unpacking position and a tailoring position.
[0012]
[Action]
Since the roll paper unpacking tailoring device according to the present invention has the above-described configuration, in the skin removing device, the skin incision device incises the skin containing the roll paper packing material, and then the roll paper holding and rotating device is the roll paper. The skin cut by rotating is fed from the lower side of the roll paper to the transport device, and the transport device transports the skin to a predetermined discharge position. At this time, the winding direction of the roll paper set in the skin removing device may be the correct direction or the reverse direction. If the roll paper is wound in the correct direction, only the skin is removed from the roll paper, and the main paper is not fed out. On the other hand, when the roll paper is set in the reverse direction, the leading edge of the underlying paper is also fed out at the same time when the skin is fed out and is continuously conveyed by the conveying device. The book sheet detecting means detects whether or not the book sheet has been fed out on the transport device. Therefore, when the roll paper is set in the reverse direction and the book sheet is fed out on the transport device, it detects it. A paper detection signal is output. The paper cutting device operates based on the paper detection signal and cuts the paper. Thereby, the skin including the peripheral surface packing material of the roll paper is removed, and preparation for tailoring is completed.
[0013]
The roll paper transporting means transports the roll paper after the skin is removed by the skin incision device to the tailoring device. During this transport, if the book paper detection means does not output a book paper detection signal (and therefore the roll paper is set in the correct direction), it is determined that the roll paper is set in the correct direction and the roll is detected. The paper is set in the tailoring device in that direction. On the other hand, when the book paper detection means outputs a book paper detection signal (and therefore when the roll paper is set in the reverse direction), it is determined that the roll paper is set in the reverse direction, and the roll paper is rotated 180 degrees. Turn it around and turn the winding direction Reverse Set it on the tailoring device. Thereby, the roll paper is always set in the tailoring device in the correct winding direction.
[0014]
The tailoring apparatus performs a tailoring operation in which the leading end of the main sheet is fed out from the roll paper, tailoring is performed for splicing the front end of the main sheet, and then the leading end of the main sheet is rewound onto the roll sheet. This tailoring operation is performed in parallel with the skin removing operation by the skin removing device, whereby the skin removal and the tailoring can be performed in a short time to improve the processing capability.

Next, the operation of the roll paper unpacking tailoring apparatus having the above configuration will be described. The following operations are automatically performed by a sequence control device (not shown).
[0035]
In FIG. 1, first, at the roll paper supply position, the roll paper 1 after removing the packing material on both end faces is placed on the first transport carriage 6, and the transport carriage 6 moves the roll paper 1 to the unpacking position P1. Carry and stop. The state at this time is the state shown in FIG. Here, the setting direction of the roll paper 1 placed on the transport carriage 6 is the right direction in which the winding direction of the main paper is left-handed (winding direction that becomes outward as it goes in the clockwise direction) as shown with exaggerated broken lines. And is usually set in the correct direction. However, it is not necessary to strictly regulate the set direction. It is assumed that the roll paper 1 is set on the transport cart 6 in the correct direction. When the transport carriage 6 carries the roll paper 1, the lifting table 12 holds the roll paper 1 at a position higher than the support roller 14, so that the roll paper 1 does not hit the support roller 14. Further, the mounting arm 23 holding the height determining sensor 22 for detecting the height of the roll paper 1 is in a vertical retracted position and does not interfere with the conveyance of the roll paper 1.
[0036]
When the transport cart 6 transports the roll paper 1 and stops at a predetermined position, the mounting arm 23 moves to a horizontal detection position as shown in FIG. 4B, and then the lifting table 12 of the transport cart 6 rises. The roll paper 1 is lifted to a predetermined height detected by the height determining sensor 22. Thus, positioning in the height direction of the roll paper 1 is performed by the elevating table 12 of the transport carriage 6 so that positioning can be performed in a shorter time than when using the chucking arm.
[0037]
When the positioning of the roll paper 1 is completed, as shown in FIG. 4C, the skin drop prevention plate 35 is pressed against the outer peripheral surface of the roll paper 1, and the skin incision device 16 is operated in this state, and a predetermined amount of Cut the skin 2 (packing material and several sheets of surface paper). At this time, the portion below the incision position of the epidermis 2 tries to drop immediately as the incision is made, but the epidermis fall prevention plate 35 holds the epidermis and therefore does not fall. Next, as shown in FIGS. 4D and 4E, the elevating table 12 is lowered, the roll paper 1 is placed on the pair of support rollers 14, and the skin fall prevention plate 35 is slowly retracted to complete the incision. Are placed on the belt conveyor 26 at the same time. In this way, by slowly placing the skin 2 incised by the skin fall prevention plate 35 on the belt conveyor 26 at the same time, the incised skin 2 is prevented from being irregularly folded or crumpled. The belt conveyor 26 can be satisfactorily conveyed in a flat state.
[0038]
After the roll paper 1 is placed on the pair of support rollers 14, the first transport carriage 6 returns to the original supply position and prepares for the next transport of the roll paper 1. On the other hand, at the unpacking position P1, as shown in FIG. 4 (f), the pair of support rollers 14 rotate to rotate the roll paper 1 in the direction indicated by the arrow A, and send the skin 2 out. At the same time, in FIG. 2, the belt conveyors 26 and 27 are also rotated to feed the skin 2 toward the skin storage device 40. At this time, the upper belt conveyor 28 is in a position indicated by a two-dot chain line. Further, the moving press plate 48 is stopped at a position lower than the inlet 45.
[0039]
In FIG. 2, the front end of the skin 2 sent by the belt conveyor 27 is guided by the belt conveyors 27 and 28, enters the nip portion of the rollers 32 and 33, is nipped by the rollers 32 and 33, and is conveyed. In addition, when it is difficult for the front end of the skin to enter the nip portion of the rollers 32 and 33, the roller 33 is separated upward, and when the front end of the skin 2 passes, the roller 33 is lowered to nip the skin 2. You may operate. After the front end of the skin 2 is nipped by the rollers 32 and 33, the rollers 32 and 33 nip and transport the skin 2 and push it into the storage space 41. The pushed skin is forcibly pushed into the storage space 41 and stored. In this way, the rollers 32 and 33 arranged at the entrance of the storage space 41 nip the outer skin 2 and push it into the storage space 41, so that the outer skin is pushed into the storage space 41 and a paper jam occurs. And the skin 2 delivered from the roll paper 1 is reliably fed into the storage space 41 up to the rear end.
[0040]
On the other hand, in the roll paper 1, as shown in FIG. 4 (g), the rear end of the cut skin 2 is sent out, thereby removing the packing material and the defective surface paper on the peripheral surface of the roll paper 1. Is done. Further, the leading edge of the main paper 1b remaining on the roll paper 1 side is exposed. By the way, the winding direction of the main paper 1b is the direction in which the main paper 1b is wound when the roll paper 1 is rotated in the direction of arrow A for sending out the skin 2, so that the leading edge of the main paper 1b is not sent out. . Accordingly, only the cut skin 2 is fed out, and the fed skin 2 is pushed into the storage space 41 as described above. After the skin 2 is sent out from the roll paper 1, the rotation of the support roller 14 is stopped. By this time, the second transport carriage 8 has come between the pair of support rollers 14 at the unpacking position P1, and is waiting at that position. When the rotation of the support roller 14 stops, as shown in FIG. 4 (h), the lifting table 12 of the transport carriage 8 rises to hold the roll paper 1, and then the transport carriage 8 moves to the roll paper 1. The paper travels to the tailoring position P2 (see FIG. 1) without changing the winding direction, and the roll paper 1 is supplied to the tailoring device 7.
[0041]
On the other hand, at the unpacking position P1, after the second transport carriage 8 carries out the unrolled roll paper 1, the first transport carriage 6 on which the next roll paper 1 is loaded moves, and the above procedure is performed. The unpacking operation for the next roll paper 1 is repeated. The above operation is repeated for a plurality of roll papers, and many skins are pushed into the storage space 41. Then, after an appropriate amount of skin is fed into the storage space 41, in FIG. 2, the moving press plate 48 rises, and the skin on it is crushed between the fixed press plate 47 and made smaller. Thereafter, the dispensing pawl 53 of the dispensing device 52 moves horizontally, and the crushed skin is discharged from the outlet 58 and is put into the waste bin 60 that is waiting below the outlet. As described above, the epidermis can be crushed and discharged into the waste box 60.
[0042]
When the roll paper unpacking operation according to the above procedure is performed in the skin removing device 5 provided at the unpacking position P1, the tailoring operation is performed in the tailoring device 7 in parallel. That is, as shown in FIG. 9 (a), when the second transport carriage 8 carries the unrolled roll paper 1 and moves to the tailored position, it waits at the position indicated by the upper two-dot chain line 70A. The chucking arm 70, which has been turned, holds the roll paper 1 placed on the transport carriage 8 and then moves up to a predetermined height position for tailoring as shown in FIG. 9B. . By the way, the winding direction of the roll paper 1 set in the skin removing device 5 is left-handed (winding direction that goes outward as it goes in the clockwise direction) as shown in FIGS. Since the roll paper 1 is set in the tailoring apparatus 7 while maintaining the winding direction, the roll paper 1 held on the chucking arm 70 is also wound leftward.
[0043]
Next, as shown in FIG. 9 (b), the roll paper 1 is rotated in the direction of arrow A so that the leading edge of the main paper 1b faces the tailoring table 71, and then shown in FIGS. 9 (c) and 9 (d). In this manner, the roll paper 1 is rotated in the direction of arrow B, and the leading edge of the main paper 1b is sent out on the tailoring table 71. Thereafter, the tailoring tool 72 cuts the main paper 1b on the tailoring table 71 into a substantially V shape, affixes a double-sided tape along the leading edge thereof, affixes a loosening prevention tab to the leading edge, and then FIG. ), The roll paper 1 is rotated in the direction of arrow A to rewind the main paper 1b on the tailoring table 71, and the leading end thereof is attached to the surface of the roll paper 1 with a loosening prevention tab. As a result, a predetermined tailoring is performed on the roll paper 1.
[0044]
On the other hand, in parallel with these operations, as shown in FIG. 9B, the transport carriage 8 lowers the lifting table 12, and goes to receive the next roll paper 1 at the unpacking position P1. Next, as shown in FIG. 9 (e), the third transport cart 75 comes under the roll paper 1 held by the chucking arm 70 and stands by. Then, as shown in FIG. 9 (f), when the tailoring operation for the roll paper 1 is completed, the chucking arm 70 is lowered and the lifting table 12 of the transport carriage 75 is raised to receive the roll paper 1. After that, the chucking arm 70 releases the holding of the roll paper 1 and retreats upward as shown in FIG. 9G, and the transport cart 75 discharges the roll paper 1. Next, the second transport carriage 8 carries the next roll paper 1 again, and the tailoring operation according to the above procedure is performed.
[0045]
As described above, the skin removing device 5 and the tailoring device 7 perform the skin removal and tailoring of the roll paper in parallel. For this reason, the skin removal and the tailoring are performed by the same device as in the prior art. It is possible to improve the processing capacity compared to the above. Moreover, in the skin removal apparatus 5, since the positioning of the roll paper in the height direction is performed by the first transporting carriage 6 that has transported the roll paper, the time required for positioning compared with the case where the swiveling chucking arm is used. The processing time of one cycle is shortened and the processing capacity is increased. The tailoring device 7 uses the chucking arm 70 to hold the roll paper 1, but the processing time for one cycle in the tailoring device 7 is shorter than the processing time in the skin removing device 5. There is no reduction in ability. Further, since the winding direction of the roll paper 1 correctly set in the skin removal device 5 and the winding direction of the roll paper 1 set in the tailoring device 7 are the same, the roll paper 1 is correctly set in the skin removal device 5. In this case, it is not necessary to change the direction of the roll paper 1 when taking it out and carrying it to the tailoring device 7, so that the transport from the unpacking position P1 to the tailoring position P2 can be performed in a short time.
[0046]
By the way, the above operation | movement is a thing when the winding direction was left-handed as shown to Fig.4 (a), when putting the first roll paper 1 on the 1st conveyance cart | bogie 6. As shown in FIG. If set in this state, the skin removal and tailoring operations can be performed in accordance with the above procedure. However, the winding direction of the roll paper 1 when it is put on the first transport cart 6 may be reversed. The roll paper unpacking tailoring apparatus of the present embodiment can cope with such a case, and the corresponding operation will be described below.
[0047]
In the skin removing device 5, as shown in FIG. 10A, when the skin 2 cut out from the roll paper 1 is sent out and passes under the optical sensor 39, the optical sensor 39 detects the tip, and a timer ( (Not shown) starts counting. Then, when the predetermined time set longer than the time required for the rear end of the skin 2 to pass under the optical sensor 39 is counted up, the determination unit checks the output of the optical sensor 39. If the roll paper 1 is set correctly, as shown in FIG. 10B, the skin 2 and the leading edge 1b of the paper do not exist below the optical sensor 39, so the optical sensor 39 outputs an off signal. It is determined that the roll paper 1 has been set correctly. At this time, the rotation of the support roller 14 is stopped, the roll paper 1 is placed on the transport carriage 8, and the process proceeds to the next step. Further, at that time, the turntable 10 does not operate at all, so that the roll paper 1 is supplied to the tailoring device 7 while maintaining the same direction.
[0048]
On the other hand, when the roll paper 1 is not set correctly, as shown in FIG. 10C, the main paper 1 c is fed out by the rotation of the roll paper 1, and the main paper 1 c passes under the optical sensor 39. is doing. For this reason, the optical sensor 39 outputs an ON signal that detects the main paper 1c, thereby determining that the roll paper setting direction is reversed. In this case, as shown in FIG. 10D, the support roller 14 stops rotating, and then the book paper cutting device 38 cuts and separates the book paper 1c, and then the support roller 14 rotates in the reverse direction to roll paper. 1 is rotated in the reverse direction, and the leading end 1b of the paper is rewound to the state shown in FIG. Thereafter, the roll paper 1 is placed on the transport carriage 8 and sent out. Further, information indicating that the roll paper setting direction is reversed is transmitted to the control device of the turntable 10 (see FIG. 1).
[0049]
The transport carriage 8 on which the roll paper 1 is placed stops on the turntable 10, and then the turntable 10 rotates 180 degrees. As a result, the transport carriage 8 and the roll paper 1 are turned 180 degrees, and the direction of the roll paper 1 is reversed, so that the winding direction of the roll paper 1 is corrected to the correct direction. Thereafter, the transport cart 8 moves to the tailoring position P2, and tailoring is performed according to the procedure described above. As described above, the skin removal and tailoring operations can be performed without hindrance regardless of whether the winding direction when the roll paper 1 is loaded on the first transport carriage 6 is normal or reverse. There is no need to monitor and correct the winding direction.
[0050]
In the above embodiment, the turntable 10 is used to change the setting direction of the roll paper 1. However, the present invention is not necessarily limited to the case where the turntable is used, and the transport carriage 8 is oriented at an appropriate position. It is good also as a structure to convert. However, it is preferable to use the turntable 10 as in the illustrated embodiment because the direction can be easily changed in a narrow place. Moreover, it is good also as a structure which turns only the raising / lowering table 12 holding the roll paper 1 180 degree | times instead of turning the conveyance carriage 8 as a whole and changing the winding direction of the roll paper 1 hold | maintained. In this case, the turntable 10 becomes unnecessary.
[0051]
Further, in the above embodiment, when the skin of the roll paper 1 is incised by the skin removal device 5, the roll paper 1 is lifted and positioned by the lifting table 12 of the transport carriage 6. The roll paper 1 may be held and positioned by a chucking arm as used in the above. Furthermore, in the said Example, although the conveyance trolley is used for conveyance of the roll paper 1, it replaces with a conveyance trolley and an appropriate conveyor, for example, a slat conveyor, may be used. In this case, however, a turntable is provided in the middle of the path from the unpacking position P1 to the tailoring position P2, and the roll paper 1 can be turned 180 degrees.
[0052]

Since the apparatus is provided separately, the skin removal operation and the tailoring operation can be performed in parallel, and the skin removal and tailoring can be performed in a short time to improve the processing capacity. ing. Furthermore, since the skin removal device used here is configured to feed out the cut skin from the lower side of the roll paper, when the roll paper is set in the correct direction, when the cut skin is sent out from the roll paper The paper is not fed out. Therefore, the operation of cutting or rewinding the fed paper is unnecessary, the skin can be removed quickly, and the roll paper taken out from the skin removing device remains in that direction. Therefore, the time required to move the roll paper from the skin removing device to the tailoring device can be shortened, and the effect that the processing capability can be increased from these points can be obtained.
[0053]
In addition, the epidermis removal device sent out the epidermis Later The paper is fed onto the transport device ing The paper detection means capable of detecting this and the paper cutting device for cutting the paper are provided, so that even when the roll paper is set in the reverse direction and the paper is fed out, it can be detected and cut. It is possible to remove the epidermis without hindrance. Moreover, when the roll paper after removal of the skin is transported to the tailoring device, the roll paper transport means turns the roll paper 180 degrees. Reverse the winding direction Therefore, the tailoring device can be set in the correct direction. Thus, in the apparatus of the present invention, there is no need for the operator to accurately monitor and set the roll paper correctly or to change the setting direction, which greatly increases the work load on the operator.
