DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leading end process for splicing, which is a process used for a rotary press or the like, in which the end of a spliced sheet is formed by cutting the sheet into a predetermined shape. Attach adhesive tape (double-sided tape) to the paper edge,
The present invention relates to a winding and tailoring apparatus that automatically performs a tailoring process of fixing the paper end to a winding outer periphery with a tab for preventing loosening.

[0002]

2. Description of the Related Art Conventionally, there has been developed an apparatus for automatically performing a tailoring operation for splicing for winding.
It is disclosed in JP-A-3-295354 and JP-A-5-238610.

[0003] A tailoring device described in Japanese Patent Application Laid-Open No. 63-295354 discloses that a winding carried in by a bogie or the like is held by a chucking arm and lifted to a predetermined position, and a surface layer of the winding is cut in a width direction. Then, the paper (packing material and defective paper on the surface layer) of the surface layer is removed, and then the winding is rotated to send the leading end of the paper onto a substantially horizontal work table arranged adjacent to the winding. After adsorbing and holding on the work table, this paper is cut into a V-shape to form a V-shaped spliced paper end, and a double-sided tape is attached along the V-shaped side of the paper end. At the same time, a specially shaped tab for fixing the paper end is attached to the V-shaped tip, and then the winding is rotated in the paper end winding direction to rewind the paper end, and the paper end is wound using the tab. It was configured to be attached to the outer peripheral surface of the bird.

A tailoring device described in Japanese Patent Application Laid-Open No. 5-238610 is incorporated in a paper feed unit of a rotary press, and winds up a turret provided in the paper feed unit during paper feeding. Let the chuck on the side that does not hold the winding hold it,
The surface layer of the winding is cut in the axial direction (paper width direction), and then the winding is rotated to feed out the cut waste paper, and the leading end of the paper is also fed downward together with the waste paper. Is cut in the width direction of the paper to form a paper end for splicing.Attach the top of a plurality of strip-shaped winding paper tip fixing tabs to the end of the paper, and paste adhesive tape along the paper end. After that, the winding is rotated in the paper end winding direction to rewind the paper end, and the paper end is attached to the outer peripheral surface of the winding using the tab.

[0005]

However, all of the conventional tailoring apparatuses have problems. That is, in the tailoring device described in JP-A-63-295354, the take-up is handled by a chucking arm. It is necessary to retreat, the cycle time becomes longer, and the work of cutting the winding surface layer becomes necessary, so the cycle time becomes longer from this point. There is a problem that a large work table is required to hold the table and cut it into a V-shape, and that the size of the apparatus is large and a large installation space is required. In addition, there is a problem that running cost is high because an expensive tab having a special shape is used for fixing the paper edge.

On the other hand, the tailoring device described in Japanese Patent Application Laid-Open No. Hei 5-238610 is mounted on the paper feed section of a rotary press, and therefore requires the same number of tailors as the number of rotary presses. There was a problem that the cost was very high. In addition, since the waste surface is removed by cutting the winding surface layer, the amount of waste paper generated in the paper feed unit of each rotary press is large, and there is a problem that the work of discharging the waste paper requires a great deal of labor. Was.

The present invention has been made in view of the above-mentioned problems, and can be installed as a tailoring device separately from a rotary press, requires a small installation space, and requires the use of a specially shaped tab. It is an object of the present invention to provide a winding tailoring device that can reduce the cycle time without using the same.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the present invention comprises a pair of support rollers on which a winding is placed and held. A take-up support means is used in which the taker is positioned at a tailoring position of a predetermined height and can be rotated in both forward and reverse directions. By adopting the winding support means of this configuration, the winding to be processed is simply put on the supporting roller, and by raising the supporting roller, the winding can be positioned at a predetermined height for performing the tailoring processing on the winding. After the tailoring process, it is possible to discharge the winding simply by lowering the pair of support rollers, and the time required for winding handling can be reduced as compared with the case where a conventional chucking arm is used. Can be shortened.

Further, the present invention omits the cutting operation of the surface layer portion of the winding in the paper width direction, and instead, the winding supporting means holds the winding at a tailoring position of a predetermined height and rotates the winding. At this time, there is provided a paper edge detecting means for detecting that the paper edge of the winding has reached a predetermined position in the circumferential direction. And
Further, a work table provided with a scraper for guiding the paper end away from the outer peripheral surface of the take-up when the take-up is rotated in the paper end pay-out direction, and a support surface capable of supporting the actual paper fed through the scraper. And running in a direction crossing the book paper supported on the support surface and facing the support surface of the work table, cutting the book paper to form a paper end for splicing, and a tab at the paper end. A tailoring unit for performing a tailoring operation such as sticking and sticking with an adhesive tape is provided. With this configuration, the take-up held by the take-up support means is rotated in the paper-end winding direction, and the paper-end detecting means detects that the paper end has passed through the scraper and has reached a position at a proper distance from the scraper. Detecting, then, by reversely rotating the winding, the paper end can be sent out onto the support surface of the work table through the scraper, and the paper sheet unwound from the winding and positioned on the support surface The tailoring unit can perform tailoring operations such as cutting, tab application, and adhesive tape application.

Embodiments of the present invention shown in the drawings will be described below. FIG. 1 is a schematic cross-sectional view of a winding tailoring device according to an embodiment of the present invention, and FIG. 2 is a schematic plan view thereof, with some parts omitted. Note that this tailoring device converts the winding 1 into the form shown in FIG.
Is a paper end 1c whose most part of the entire width is a straight line parallel to the winding axis, an adhesive tape 40 is attached to the paper end 1c, and a plurality of tabs 60 are provided on the winding surface.
In this case, a tailoring operation of tailoring is performed to the form that is pasted. The tab 60 used here is shown in FIG.
As shown in (b), it is simply strip-shaped and has a perforation 60a for separation formed at the center.

In FIGS. 1 and 2, reference numeral 1 denotes a winding to be tailored, which is shown as being held at a position where the tailoring process is performed. Reference numeral 2 denotes a carriage for supplying and discharging the winding 1, and runs on the rail 3 with the winding 1 placed on the upper surface 2a to convey the winding 1 in its axial direction. I have. In addition, the conveyance means of the winding 1 is not limited to the case where the carriage 2 is used, and other means such as a conveyor may be used. The winding 1 used in the present embodiment is obtained after a packaging material removing device (not shown) removes a packaging material on the outer periphery and a defective book paper on a surface layer.
The paper is supplied so that the winding direction of the paper is counterclockwise (the leading end 1a of the paper is clockwise).

Reference numeral 4 denotes a take-up support means, which is disposed at a position sandwiching the traveling path of the bogie 2 and is capable of holding the take-up 1 thereon and holding a pair of support rollers (hereinafter referred to as balers) 5.
Drive means (not shown) for rotating the baler 5 in both forward and reverse directions, and a lifting mechanism 6 for lifting and lowering the baler 5
Etc. are provided. The lifting mechanism 6 moves the baler 5 to a retracted position (a position indicated by a two-dot chain line in FIG. 1) in which the baler 5 is retracted so as not to interfere with the traveling of the winding 1 on the carriage 2, and a tailoring process. And a position (the position shown in FIG. 1) which is a tailoring position of a predetermined height for performing the above. Thus, the winding support means 4 can support the winding 1 with the pair of balers 5 to position the winding 1 at a tailoring position having a predetermined height, and rotate the winding 1 in both forward and reverse directions. In this embodiment, the tailoring position of the winding is determined with reference to the center axis of the winding. Therefore, if the outer diameter of the winding 1 held by the baler 5 is different, the height of the baler 5 is different. It will be. As a method of raising the winding 1 by the baler 5 and positioning the winding at the tailoring position of a predetermined height, a known technique may be appropriately adopted, for example, such that the paper tube at the center of the winding 1 has a predetermined height. A method of controlling, or a method of inputting the outer diameter of the winding in advance, calculating the ascending position of the baler 5 based on the information, and controlling the baler 5 to the height may be adopted.

In FIG. 1 and FIG. 2, reference numeral 11 denotes a side frame, and 12 denotes a side frame of the winding frame 1 which is held horizontally and in a direction perpendicular to the axis of the winding 1 (arrow X-
This is a vertical moving table held so as to be movable (in the X direction). A work table 14 is attached to the tip of the vertical moving table 12. As shown in FIGS. 3 and 4 in an enlarged manner, the working table 14 has a support surface 14a that is substantially vertical and has a width larger than the width of the winding 1, and the winding 1 is placed on the supporting surface 14a. The unfolded book can be supported.
Further, a large number of small holes for vacuum suction are formed on the support surface 14a for sucking and holding the paper so as not to move, and are connected to a vacuum suction source (not shown). Further, a scraper 16 is attached to an upper end of the work table 14. The scraper 16 has a thin metal plate 16a and a plastic film 16b attached thereto. The scraper 16 is rotated in the direction of arrow A (the direction of feeding out the paper edge) with its tip lightly pressed against the outer periphery of the spool 1. At this time, the paper end 1a can be guided away from the winding outer peripheral surface, and can be guided on the support surface 14a of the work table 14.

Below the scraper 16 and the winding 1,
Air nozzle 17 that blows air over the entire width of winding 1
Is provided. The air nozzle 17 is provided so that when the take-up 1 is rotated in the direction of arrow A and the book is fed from the take-up 1, the book is reliably peeled and fed. The air nozzle 17 blows air from under the scraper 16, but since the tip of the scraper 16 is a soft plastic film 16b, the air nozzle 17 can be easily deformed and allow air to pass therethrough. The paper blown and fed out between the winding surface can be peeled off. If necessary, a number of grooves or holes may be formed at the tip of the scraper to allow air to pass through. The air nozzle 17 is provided over the entire width of the winding 1. The central portion of the air nozzle 17 is provided with a large amount of air blow, or another air nozzle is provided only at the central portion, and the paper end is provided as described later. At the time of detection, the paper edge is surely raised from the winding surface.

When the paper end 1a is lifted from the surface of the winding roll 1 by blowing air from the air nozzle 17, the paper end 1a is arranged to prevent the paper end 1a from being turned up. Also, the paper sensor 2
Reference numeral 2 denotes a state in which the actual paper on the winding surface is not detected when the distance from the winding 1 (for convenience, the distance between the portion pressed by the press roller and the paper sensor 22) is set to a predetermined value L, but the winding is not detected. The paper edge 1a can be detected when the paper edge 1a rises by an appropriate amount from the take-up surface, and a diffuse reflection type photoelectric sensor is usually used. Thus, as shown in FIG. 3, the interval between the paper sensor 22 and the take-up 1 is set to the predetermined value L,
When the winding 1 is rotated in the direction of arrow B in a state where the outer periphery of the winding is pressed by the holding roller 23 and air is blown out from the air nozzle 17, when the paper end 1 a passes the scraper 16, the paper end 1 a The paper sensor 22 detects the air rising from the winding surface due to the blowing of air from the printer, thereby detecting that the paper end 1a has reached a predetermined position in the circumferential direction of the winding. Therefore, the paper sensor 22 and the presser roller 23 together with the air nozzle 17 arranged at the center of the winding form a paper end detecting means for detecting that the paper end of the winding has reached a predetermined position in the circumferential direction. I do.

Both are mounted on the vertical moving table 12, and as shown in FIG. 3, when the distance between the paper sensor 22 and the outer circumference of the winding is set to a predetermined value L, the scraper 16 is positioned on the outer circumference of the winding 1. It is set to be pressed lightly. A moving mechanism (not shown) for moving the vertical moving table 12 in the XX direction of FIG. 1 is connected to the vertical moving table 12 holding the work table 14 and the support table 21. ,
The vertical moving table 12 is moved to the tailoring operation position where the interval between the take-up 1 and the paper sensor 22 becomes a predetermined value L and the scraper 16 is lightly in contact with the take-up 1, and the scraper 16 is separated from the take-up 1 and It is possible to move to a retreat position which does not interfere with elevating.

Here, the tailoring operation position of the vertical moving table 12 changes according to the diameter of the winding 1. Therefore, when the vertical moving table 12 is advanced from the retracted position to the tailoring operation position, the vertical moving table 1
Control means is provided for stopping 2 at a tailoring operation position corresponding to the diameter of winding 1. Although a known technique can be used for this control as appropriate, in this embodiment, the support rod 24 is used.

The brush 77 presses the book paper 1b against the outer peripheral surface of the take-up 1,
Air is forced inside and the paper 1b is brought into close contact with the winding surface underneath, and then the tab holding roller 76 can hold down the tab 60 and adhere to the winding surface below. When the paper 1b is brought into close contact with the take-up surface with the brush 77, the take-up 1 is opposite to the arrow B when the take-up 1 is set in the paper feed unit of the printing press and the automatic splicing operation is performed. When rotated in the direction, air enters under the paper edge and the paper edge turns up,
This has the advantage that the occurrence of a splicing error can be prevented. The brush 77 may be provided so as to press the entire width of the winding 1. However, when the tab 77 is pressed by the brush 77, the portion may be wrinkled. It is preferable to adopt a configuration in which only the real paper between 60 is pressed.

Referring again to FIGS. 1 and 2, below the work table 14, there is provided a conveyor 80 for transporting the actual paper fed from the winding machine 1 as shown by a two-dot chain line 1d. A waste box 81 is provided downstream. The conveyor 80 used here is optional as long as the paper from the winding 1 can be discharged to a waste box 81 on the downstream side. In the present embodiment, however, the first belt conveyor 80a provided at a fixed position is provided. A belt sand conveyor having a second belt conveyor 80b for transporting the paper between the first belt conveyor 80a and the first belt conveyor 80a is used. When such a belt sand conveyor 80 is used, the paper can be reliably sandwiched and conveyed, and can be discharged to the waste box 81.

The tailoring operation of the winding tailoring device having the above configuration will be described below. The tailoring operation is automatically performed by a sequence control device (not shown) provided in the tailoring device.

First, in FIG.
Is retracted downward, and the vertical moving platform 12 is also retracted rearward, and the take-up 1 is carried in by the bogie 2, and when the bogie 2 stops at a predetermined position, the baler 5 rises and is put on the bogie 1. The winding 1 is lifted and held at a predetermined height for performing a tailoring operation. Here, the winding 1 is the one after the packaging material on the outer periphery and the defective real paper on the surface layer have been removed by a packaging material removing device (not shown), so that the winding direction of the real paper is counterclockwise. (The paper edge 1a faces clockwise) and is carried in the carriage 2.

Next, with the support rod 24 holding the holding roller 23 at the tip protruding from the support table 21, the vertical moving table 12 moves toward the winding 1 as shown in FIG. 13 (b). When the presser roller 23 hits the winding 1 and stops moving, and the support rod 24 is pushed to a predetermined position with respect to the support 21, a position sensor (not shown) detects this and a detection signal from the position sensor. The vertical moving base 12 stops.
As a result, the vertical moving table 12 stops at the tailoring operation position corresponding to the diameter of the winding 1, the distance between the paper sensor 22 and the winding 1 becomes a predetermined value L, and the scraper 16 is lightly pressed against the winding 1. It will be in the state that was done.

Next, the air nozzle 17 starts blowing air, and the baler 5 rotates to rotate the winding 1 in the direction of arrow B (paper end winding direction). During this rotation, the paper edge 1a of the book paper
When the paper passes the scraper 16, the paper edge 1 a rises due to the blowing of air from the air nozzle 17, and the paper sensor 22 detects this, and detects that the paper edge 1 a has arrived before the paper sensor 22. After this detection, as shown in FIG. 13C, the baler 5 rotates in the reverse direction, and the winding 1 is rotated in the paper end feeding direction indicated by the arrow A. Thereby, the paper end 1a is sent downward, is peeled off from the surface of the winding 1 by blowing air from the scraper 16 and the air nozzle 17, and is sent out to the lower belt sand conveyor 80 to be nipped. The paper end 1a is nipped by the belt sand conveyor 80, and the baler 5 stops when the paper edge 1a is slightly fed, and the winding 1 also stops. At this time, since the lower end of the paper unwound from the winding 1 is nipped by the belt sand conveyer 80, the paper is kept in a state of being appropriately tensioned.

Next, in FIG. 14A, a vacuum is supplied to the suction holes of the support surface 14a of the work table 14, and the book paper 1b is sucked and held. The newspaper 1b tailoring unit 30 in this state is moved in the arrow Y ₁ direction, the paper edge 1 for splicing paper
Cut to form c. That is, when the travel of the arrow Y ₁ direction tailoring unit 30, first, the main cutter 32 cuts from the left near the actual paper 1b to actual paper 1b, so on are cut in a straight line the actual paper 1b laterally left side cutter When 33A reaches the left end of the book sheet 1b, the tailoring unit 30 temporarily stops at that position, at which position the side cutter 33A cuts the left end of the book sheet 1b diagonally, and then the tailoring unit 30 again moves the arrow Y _1.
The main cutter 32 cuts the paper 1b in the horizontal direction, and when the right side cutter 33B reaches the right end of the paper 1b, the tailoring unit 30 temporarily stops, and at that position, the side cutter 33B 1b is cut obliquely at the right end, and then the tailoring unit 30 again moves the arrow Y
_After traveling in _one direction, the main cutter 32 cuts the main paper 1b in the horizontal direction. As described above, the paper splicing end 1c is formed. The separated paper is a belt sand conveyor 8
0 discharges to the waste box 81.

Next, in FIG. 14 (b), the tailoring unit 30 is moved in the arrow Y ₂ direction, tab bonding portion 35 located on the upstream side, Yuki paste one after another the tabs 60 on the paper edge 1c, The tape application section 34 on the downstream side attaches the adhesive tape 40 to the paper end 1c.

After the attachment of the tab 60 and the adhesive tape 40 is completed, as shown in FIG.
5 operates to wind up the tab holding roller 76 and the brush 77 1
And the vacuum suction of the support surface 14a is released. In this state, the baler 5 rotates the winding 1 in the direction of arrow B, and rewinds the paper end 1c located on the support surface 14a onto the outer periphery of the winding 1. At this time, the brush 77 is
b is pressed against the outer peripheral surface of the winding 1 to push air into the inside, and the book paper 1b is brought into close contact with the lower winding surface,
Next, the tab pressing roller 76 presses the tab 60 and affixes it to the winding surface below it. As described above, winding 1 is shown in FIG.
The state shown in FIG.

After that, the baler 5 descends to lower the tailored winding 1, puts it on the bogie 2 waiting below, and unloads the winding 1 with the bogie 2. Thus, one tailoring operation is completed.

In the above embodiment, as shown in FIG. 5A, the main paper 1b of the winding 1 is cut in parallel to the axis of the winding to form the paper end 1c for splicing. However, the cutting direction for forming the end of the paper for splicing is not necessarily required to be parallel to the axis of winding, and may be slightly inclined as long as it crosses the main paper. That is, as shown in FIG. 16, a paper end 1c cut diagonally may be adopted. In order to perform such an oblique cut, a configuration in which the tailoring unit 30 travels in an oblique direction as shown in FIG. 17 may be used.
Here, when the inclined paper end 1c as shown in FIG. 16 is employed, if the inclination angle is too large, the length of the support surface 1a supporting the main paper at the time of cutting in FIG. 17 is not preferable. Therefore, it is preferable that the inclination angle of the leading end of the paper end 1c be about 30 ° or less with respect to the winding axis.

[0044]

According to the present invention, the following effects can be obtained. As shown in FIG. 5 or FIG. 16, by adopting a method of cutting the leading end of the book paper in a straight line parallel or inclined to the winding axis, the length of the supporting surface for supporting the book paper for cutting the book paper is reduced. , Can be made shorter than in the case of cutting into a V-shape, and since the support surface is shortened, the support surface can be arranged vertically, so that the device can be made compact and the installation space is small. I'm done. Running cost is low because it is not necessary to use expensive tabs with special shapes. Since the winding is held by a pair of supporting rollers (balers) that move up and down, the cycle time can be reduced and productivity is improved as compared with the case where a chucking arm is used. Since one tailoring device can handle a plurality of printing presses, equipment costs can be reduced.
